Opis:
The most worldwide method of liquidating underground hard coal mines is by spontaneous flooding as the result of the discontinuation of the rock mass drainage. Due to the hydrological reconstruction of the previously disturbed water system by mining operations, the movements of the rock mass with the opposite direction than subsidence appear. These movements are called rock mass uplift. This paper aims to present possible hazards related to land surface objects and the environment, which can appear during the flooding of the underground mine. The issue of proper forecasting of this phenomenon has so far been marginal in world literature. To date, only a few analytical methods have been used to predict the possible effects of surface deformation. Nowadays, the most common analytical method of forecasting surface deformation caused by the liquidation of underground workings by flooding is Sroka’s method. In this paper, the authors have presented analyses of flooding scenarios developed for a Polish mine and their impact on the land surface as well as the environment. The scenarios presented in the manuscript were selected for analysis as the most probable concerning the mine and the future plans of the mining enterprise. The process of flooding coal mines results in several risks for surface objects and underground infrastructure. This is why the uplift caused by the flooding of the mine should be predicted. The resulting uplifting movements can also, apart continuous deformation lead to the creation of much more dangerous phenomena involving discontinuous deformations.
Najbardziej znaną na świecie metodą likwidacji podziemnych kopalń węgla kamiennego jest sa- moistne zatopienie jej w wyniku zaprzestania odwadniania górotworu. W związku z hydrologiczną odbudową zaburzonego wcześniej systemu wodnego przez eksploatację górniczą, pojawiają się ruchy górotworu o kierunku przeciwnym do osiadania. Ruchy nazywane są wypiętrzaniem masywu skalnego. Celem artykułu jest przedsta- wienie możliwych zagrożeń związanych z obiektami budowlanymi zlokalizowanych na powierzchni terenu oraz środowiskiem, jakie mogą wystąpić podczas zatapiania kopalni podziemnej. Kwestia prawidłowego prognozo- wania tego zjawiska była dotychczas w literaturze światowej marginalna. Do tej pory wykorzystano tylko kilka metod analitycznych do przewidywania możliwych skutków deformacji powierzchni ziemi. Obecnie najbardziej docenianą analityczną metodą prognozowania deformacji powierzchni spowodowanych likwidacją podziemnych wyrobisk przez zatapianie jest metoda Sroki. W artykule autorzy przedstawili analizę scenariuszy likwidacji opra- cowanych dla polskiej kopalni i ich wpływu na powierzchnię terenu oraz środowisko. Przedstawione w rękopisie scenariusze zostały wybrane do analizy jako najbardziej prawdopodobne ze względu na działalność kopalni i przy- szłych planów przedsiębiorstwa górniczego. Proces zatapiania kopalń podziemnych powoduje szereg zagrożeń dla obiektów naziemnych i infrastruktury podziemnej. Dlatego należy prognozować wypiętrzenie spowodowane likwidacją kopalni przez zatapianie. Powstające ruchy podnoszące mogą również, poza ciągłą deformacją, prowa- dzić do powstania znacznie groźniejszych zjawisk związanych z deformacjami nieciągłymi.

Opis:
The study involves a preliminary analysis of short-duration high-intensity rainfall events in the area of Cracow. The events were selected from a 2-year data record from the MPWiK (Miejskie Przedsiębiorstwo Wodociągów i Kanalizacji [Municipal Water and Sewage Company]) in Cracow. A spatial analysis was carried out by comparing rainfall events with highest single totals which occurred at the same time at all observed precipitation stations. Extracted were nine cases from the data record of 2013 and ten from the data record of 2014. Each of the analysed events was classified according to the Chomicz scale for rainfall intensity in order to distinguish maximum rainfalls, in particular of the following types: heavy rainfalls, rainstorms and torrential rains. Additionally, observed were cases of the most unfavourable rainfall events, i.e. ones with the highest totals in the observed year. In both 2013 and 2014, certain areas in Cracow were observed to be characterised by a pattern of repeating rainfall types. Also, a change in the rainfall category was observed from lower into higher and reverse in certain areas represented by the same gauging stations. At the stations located in varying distances within one urban area of Cracow, the intensity of rainfall varied from rainstorm A1 to torrential rain B1.

Flat-bottomed propeller boats are vessels which have been well-known for more than a hundred years. However, in Poland they are less popular and are used only for recreational purposes. The project implemented by a consortium of Polish research centers and companies within the limits of the competition for the Applied Research Program (financed by The National Centre for Research and Development, NCBR) led to the creation of the first dedicated rescue unit in Poland. The Main School of Fire Service (SGSP) together with the Automotive Industry Institute (PIMOT) carried out practical tests on both: flowing water (the Narew river) and standing water (the Zegrze Lake).
Płaskodenne łodzie z napędem śmigłowym są jednostkami pływającymi znanymi od ponad stu lat. W Polsce jednak są mało popularne i jeżeli są wykorzystywane, to jedynie w celach rekreacyjnych.

Opis:
The paper provides an overview analysis concerning the major elements of the environment of mining areas, described based on research to develop a method for the assessment of flooding threat in mining areas. The mechanism of flooding-induced changes in the surface of mining areas under conditions of restoring natural water flows in the USCB is analyzed. The state-of-the-art has been discussed in the context of environmental elements used to evaluate water invasion in mining and post-mining areas, taken from hydrogeology, hydrology, mining, and environmental protection studies. The selected features of the mining environment are characterized, in particular: the area limiting the flow of water, including the surface of the mining area and the aquifer base, local outflow bases and local water drainage basins, depression funnel, hydraulic connections between mines, surface waterways and natural lakes and ponds as well as inundated areas, floods, morphological troughs, depression and non-flood basins.

Opis:
Bajocian (Middle Jurassic) transgressive-regressive sequences (TRS), outcropping in the Rosario Nuevo Creek (Tezoatlán Basin, Tecocoyunca Group) in Oaxaca State, Mexico, represent one of the Jurassic phases of opening and widening of a trans-Pangaean marine corridor (called also the Hispanic Corridor) and show a retrogradational-progradational set of sedimentary successions with decipherable and diverse facies. Two TRSs have been distinguished. The lower one starts with fluvio-deltaic sandstones including pedogenic horizons. Drowning of the deltaic plain and gradual rising of the water table is marked by change in vegetation: from large trees to low-rise vegetation with characteristic clumps of dense roots cemented by siderite. The delta plain succession is topped by a thin coal seam, followed by a transgressive surface. Ensuing laminated mudstones of restricted marine origin pass into open marine deposits, represented by bioturbated heterolithic strata with ammonites followed by nearshore sandstones, deposited in a storm-dominated basin. A similar succession, although without the deltaic part, is repeated in the next TRS. Of note are two thin (15-20 cm) continuous beds with Thalassinoides isp. networks, present within open marine deposits. Although large Thalassinoides networks are mostly known from shallow-marine and coastal environments, the case from Mexico represents less common occurrences from a deeper marine (offshore) setting, associated with maximum flooding surfaces, sediment starvation and firmgrounds (Glossifungites ichnofacies). Occurrences of Thalassinoides meshes, precisely marking maximum flooding surfaces, are helpful in defining the hierarchy of sequence stratigraphic cycles.

Opis:
The major objective of this study is to identify the flood severity level of the study area using GIS applications. By employing this map, safer habitation zones were established. Direct personal observation and face-to-face interview was done to gather the primary data and Disaster Management center reports, Census reports of Sri Lanka, images and published research reports were used as secondary data. The severity level of flooding in this area was analyzed using SRTM imagery in ArcGIS and overlaid on a Google Earth pro map. The findings of the study established that the highly affected area consisted of around 8.953003 sq·km, the moderately affected area was around 9.190781 sq·km and the lowly affected area was approximately 9.31039 sq·km within the study area. The major causes for flood disaster in this area are the lack of drainage systems in some potential flood regions, the low landscape, poorly maintained drainage systems and the geographical arrangement of the road network. By creating this map, the inhabitants will be aware of danger areas and can relocate accordingly [3, 5-9].

Opis:
The flooding process is one of the main concerns of damaged ship stability. This paper combines the volume of fluid (VOF) method incorporated in the Navier-Stokes (NS) solver with dynamic mesh techniques to simulate the flooding of a damaged ship. The VOF method is used to capture the fluid interface, while the dynamic mesh techniques are applied to update the mesh as a result of transient ship motions. The time-domain flooding processes of a damaged barge and a rectangular cabin model are carried out based on the abovementioned method, and the computational results appear compatible with the experimental data. During the flooding process, the motion of the flooding flow at different stages is observed and compared with that observed in real conditions. The time-domain research of the flooding process is the starting point for subsequent establishment of damaged ship’s roll movement and capsizing the mechanism of dead ship condition in wave.

Opis:
Stomata begin to close within 24 h of imposing soil flooding. We investigated whether the stomatal response was triggered by reduced photosynthetic efficiency in young, fully expanded leaves of flooded plants. Chlorophyll fluorescence measurements indicated that ФpsII the effective quantum yield of PS II,decreased after stomata began to close in flooded plants. Changes in qP mirrored those of ФpsII, ФpsII was not affected by daytime patterns of stomatal conductance in well-drained plants but was reduced by stomatal closure in flooded plants. Fv/Fm a measure of the overall photosynthetic efficiency of dark- adapted plants, decreased after 57 h of flooding. Therefore, prolonged soil flooding adversely affected the thylakoid membranes. QN, a measure of the amount of captured energy dissipated as heat and therefore, unused by the photosynthetic machinery, began to increase after 32 h of flooding and continued to rise thereafter. The interdependence of the changes in chlorophyll fluorescence parameters and the flooding-induced closure of stomata is discussed.
W warunkach nadmiaru wody w glebie szparki u roślin pomidora zamykają się w czasie 24 h. W prezentowanych eksperymentach badano czy ta reakcja szparek była inicjowana przez spadek fotosyntetycznej wydajności młodych, rozwiniętych liści pomidora. Pomiary fluorescencji chlorofilu wykazały, że ФpsII, efektywna wydajność transportu elektronów PSII, spadała dopiero po rozpoczęciu zamykania szparek u zalewanych roślin. Zmiany qP, fotochemicznego wygaszania fluorescencji, odzwierciedlały przebieg ФpsII Na ФpsII nie wpływał okołodobowy rytm szparek u roślin kontrolnych. Natomiast, u roślin zalewanych, ÖpsII spadało wskutek zamykania szparek. Fv/Fm, miara całkowitej wydajności fotosyntetycznej roślin zaadaptowanych do ciemności, spadał po 57 h zalewania roślin. Wskazuje to na niekorzystny wpływ wydłużonego stresu zalewania na membrany tylakoidowe. Niefotochemiczne wygaszanie fluorescencji (NQ), która jest miarą rozpraszania niewykorzystanej energii w postaci ciepła, wzrastała po 32 h od rozpoczęcia stresu zalewania. W pracy dyskutowana jest niezależność zmian parametrów fluorescencji chlorofilu a i indukowanego stresem zalewania zamykania się szparek.

Opis:
The paper presents some results on investigations concerning development of a hybrid model for assessment of performance of the ro-ro ships in damaged conditions. The model is devoted towards assessing the performance of the damaged ro-ro ships at the preliminary stage of design. The key problems associated with preparing of such the model are associated with working out a method of assessment of the damaged ro-ro ships performance, investigating all the phenomena which associated with the flooding process of the damaged ro-ro ships and preparing the model itself. Introducing the method of assessment of the damaged ro-ro ships performance it has been assumed that there is a dependence between the arrangement of internal spaces of a ro-ro ship and flooding process. The major phenomena which have been decided to take into account when considering flooding of the ro-ro ships are the flooding understood as the flow of external water into the data damaged compartment, impact of the flooding water on the ship structure and damaged ro-ro ship motion. Knowing the damaged ro-ro ship motion characteristics in time domain it is relatively easy to assess the damaged ro-ro ship performance according to the heeling angle and assess the ro-ro ship design according to the data arrangement of internal spaces. The last research issue is to investigate if the proposed model may be appropriate tool for assessing the performance of the ro-ro ships in damaged conditions at the preliminary stage of design. The aim of this paper is to show how to incorporate the dynamics of the damaged ro-ro ships when assessing the ship performance and safety at the preliminary stage of design. The basic information on the model for estimation of the damaged ro-ro ship behavior during the flooding process is presented. The complexity of this model is shown depending on the approach applied to consider the flooding process itself. The model is devoted towards assessment of performance of the damaged ro-ro ships and it is still under the development according to a Ph.D. research at the Faculty of Mechanical Engineering Gdańsk University of Technology.

It is considered in the context of a report of Cassius Dio (LXVI 8, 1) who associated that ruler’s entry into Alexandria with an exceptional rise of flooding waters and also in view of the connection of that report with the Egyptian royal ideology which identified the king with the Nile and its flooding. The Vespasian’s decoration of the Temple of Osiris Nesmeti is analyzed in the light of representations of Nilus on the monumental staircase leading to the temple and of the stele of Florence (no. 4021).

The present research investigated the perception of the flood threat and willingness of inhabitants of regions experiencing regular severe floods to take preventive actions.Residents of two type of regions were compared: those living in a region protected by flood levees vs. residents living unprotected regions. Inhabitants of the area protected by the levees resulting in the rare experience of flood, perceived probability of flood as lower and  reported higher willingness to take preventive actions than inhabitants of the area unprotected by levees. Similarly as in many previous studies personal experience and social norms turned out to be crucial factors in determining self-protective behavior. On the other hand unlike in other studies, we found no relationship between decision makers’ willingness to take preventive actions and factors related to threat appraisal, such as the perceived magnitude of loss and the perceived probability of damage. Finally, we found that the impact of a given factor on willingness to protect oneself against a hazard may depend on the kind of measure of the protective behavior

Opis:
This research examines the relationship between urban planning and environmental conditions. As urbanisation processes increase the density of the built-up tissue of cities, this process puts a lot of pressure on land and natural resources such as rivers and soil. This article aims to verify whether environmental risks (e.g. flooding) and land protection from them is sufficiently addressed in the examined spatial policies and strategies. This problem can be observed in the Powiśle district of Warsaw where buildings are constructed in the proximity of the unregulated Vistula River and that is why there is the direct risk of flooding. It is done despite the lack of legally binding Master plans which would consider the natural risk. The literature research on the Municipality-led spatial planning policies and documents was completed with qualitative interviews with key actors in this process (planners: the authors of Master plans under construction, regarding the area of Powiśle South and North). Main designers and team members were asked about the priorities of these plans as well as their dynamics (taking more than ten years to establish those plans). An environmental analysis was conducted in the GIS mapping system of many databases. The comparison of both aspects of current development, formal urban planning and environmental protection was made in an interdisciplinary approach. The study presents an analysis of the situation for urban planning along with flood maps and other environmental conditions. The results show the lack of necessary alignment of environmental issues with the planning documentation and strategies.

Opis:
Risks relating to external hazards, either natural or man-made, have to be taken into consideration in the design of nuclear and other industrial facilities. These risks have to be studied to guarantee the availability and efficiency of safety functions which, e.g. in the case of power reactors, enable a safe shutdown, maintain the reactor in a safe shutdown state, ensure the residual heat removal and the containment of radioactive products. With a view to design protection against risks related to external hazards, these hazards have to be assessed in an appropriate manner. The methods used can be either deterministic or probabilistic. In both cases, the method strongly relies on observations (e.g. flood records) that are processed to define a maximum event for the respective facility design. Moreover, the validity of these records over a certain time frame like 100 years has to be checked. Coping with external hazards such as flooding in the future requires an in-depth assessment taking into account new data, further developed methodologies and criteria. Some of these ideas, developments and applications are provided.
