Opis:
The protection and preservation of good groundwater quality is of critical importance worldwide, nowadays. Increasing urbanization, economic development and agricultural activities, combined with limited precipitation contribute to the quantitative and qualitative degradation of groundwater resources, especially in the eastern Mediterranean region. For this purpose, a series of actions are implemented including groundwater vulnerability mapping that can depict prone to pollution aquifers which need protection and/or restoration measures. In this study, the efficiency of two well-known methodologies (COP and DRASTIC) for groundwater vulnerability and pollution risk mapping was assessed in the Sperchios river basin. The vulnerability and pollution risk maps of the two methodologies were spatially compared to each other and the observed similarities and differences were discussed and explained. The output of the study shows that in the particular geoenvironmental conditions DRASTIC method performs better than the COP, particularly in the lowland, porous media aquifer.

Opis:
Groundwater is a vital resource for domestic, agricultural, and industrial activities, as well as for ecosystem services. Despite this, the resource is under significant threat, due to increasing contamination from anthropogenic activities. Therefore, to ensure its reliability for present and future use, effective management of groundwater is important not only in terms of quantity (i.e. abstraction) but also quality. This can be achieved by identifying areas that are more vulnerable to contamination and by implementing protective measures. To identify the risk and delineate areas that are more exposed to pollution, various groundwater vulnerability assessment techniques have been developed across the globe. This paper presents an overview of some of the commonly used groundwater vulnerability assessment models in terms of their unique features and their application. Special emphasis is placed on statistical methods and overlay-index techniques. The assessment of the literature shows that statistical methods are limited in application to the assessment of groundwater vulnerability to pollution because they rely heavily on the availability of sufficient and quality data. However, in areas where extensive monitoring data are available, these methods estimate groundwater vulnerability more realistically in quantitative terms. Many works of research indicate that index-overlay methods are used extensively and frequently in groundwater vulnerability assessments. Due to the qualitative nature of these models, however, they are still subject to modification. This study offers an overview of a selection of relevant groundwater vulnerability assessment techniques under a specific set of hydro-climatic and hydrogeological conditions.

Przedstawiono monitorowanie plonu roślin kukurydzy przez pomiar zapotrzebowania mocy efektywnej bazy sieczkarni (I), grubości warstwy roślin między tylną parą walców wciągająco-zgniatających (II) i siły naporu dynamicznego strumienia masy w kanale wyrzutowym (III) z uwzględnieniem ciągłego pomiaru wilgotności. Na bazie tych metod sporządzono mapy plonów kukurydzy z wykorzystaniem DGPS. Błąd pomiaru plonu w stosunku do plonu rzeczywistego, wyznaczony w odniesieniu do całkowitej masy zebranych roślin kukurydzy wynosił dla metody I - 2-4%, II - 0,5-2% i III - 0,4-2%.
The were presented the yield monitoring methods for green maize, based on efficient power requirement measurements of silage harvester base (I), plant material layer thickness between the couple of rear feeding rolls (II), and mass flow rate impact force in the spout (III). The moisture content of silage being harvested was considered too. Using DGPS, the silage corn yield maps based on these methods were created. The yield error calculated between measurements values and real yield was related to the whole mass of green maize harvested and amounted for particular methods to: method I - 2-4%, method II - 0,5-2% and method III - 0,4-2%.

Opis:
This paper is about a new methodical approach of the joint and simultaneous application of Value Stream Mapping and Methods-Time Measurement (MTM). The focus of Value Stream Mapping is the alignment and combination of individual processes to form a continuous, efficient value stream through the organisation (macro consideration). MTM provide an exact determination of times and focuses on executions of individual tasks and working places (micro consideration). A hybrid optimisation of added value originates from the reasonable and useful combination of Value Stream Mapping and Methods-Time Measurement for increasing productivity, reducing lead time and exact determination of times.

Opis:
Aerial photographs are a source of geological information that may be unobtainable elsewhere. If the fullest use is to be made of this information for the purpose of geological mapping, there must be a planned integration of the photogeological work with the field and laboratory investigations. The appearance of the first satellites for civil purposes on the beginning of the 1970s (such as ERTS – Landsat series), of most land areas of the Earth has provided new opportunity for photogeologists. Many areas can now be studied and mapped geologically for which neither adequate maps nor vertical aerial photograps were available. The advantages of the present satellite systems and examples of their application by specialists of the Polish Geological Institute are presented in this paper. Nowadays, it is practically impossible to imagine performing geological mapping without application of remote sensing data and analysis. Development of new technologies is very fast and new borne techniques are coming like permanent scatter interferometry, laser scanning etc. However, we should always remember, that they are only very useful tools to help geologists in their field mapping art and practise.

We review main small area estimation methods for the estimation of general nonlinear parameters focusing on FGT family of poverty indicators introduced by Foster, Greer and Thorbecke (1984). In particular, we consider direct estimation, the Fay-Herriot area level model (Fay and Herriot, 1979), the method of Elbers, Lanjouw and Lanjouw (2003) used by the World Bank, the empirical Best/Bayes (EB) method of Molina and Rao (2010) and its extension, the Census EB, and finally the hierarchical Bayes proposal of Molina, Nandram and Rao (2014). We put ourselves in the point of view of a practitioner and discuss, as objectively as possible, the benefits and drawbacks of each method, illustrating some of them through simulation studies.

Opis:
Land cover mapping of marshland areas from satellite images data is not a simple process, due to the similarity of the spectral characteristics of the land cover. This leads to challenges being encountered with some land covers classes, especially in wetlands classes. In this study, satellite images from the Sentinel 2B by ESA (European Space Agency) were used to classify the land cover of Al Hawizeh marsh/Iraq Iran border. Three classification methods were used aimed at comparing their accuracy, using multispectral satellite images with a spatial resolution of 10 m. The classification process was performed using three different algorithms, namely: Maximum Likelihood Classification (MLC), Artificial Neural Networks (ANN), and Support Vector Machine (SVM). The classification algorithms were carried out using ENVI 5.1 software to detect six land cover classes: deep water marsh, shallow water marsh, marsh vegetation (aquatic vegetation), urban area (built up area), agriculture area, and barren soil. The results showed that the MLC method applied to Sentinel 2B images provides a higher overall accuracy and the kappa coefficient compared to the ANN and SVM methods. Overall accuracy values for MLC, ANN, and SVM methods were 85.32%, 70.64%, and 77.01% respectively.

The study provides a systematic description of various geometries of underground structures, giving examples of traditional and computer-assisted methods used for recording the geometry of underground structures. The methods enable the reconstruction of the structures' geometry and development of detailed drawings, a prerequisite for effective revitalisation and stabilisation old underground structures. Underlying the selection of mapping method is the analysis of the current conditions on the site, definition of potential hazards and the objectives of the restructuring programme.
