Opis:
Groundwater resources remain still in many locations the primary source of supply of drinking water for the population. This applies, in particular, to agricultural areas. That is why determination of conditions for transport of pollutants to groundwater and identification of the areas featuring the highest susceptibility to movement of these pollutants through the aeration zone is an especially significant task. The paper presents the characteristics of conditions of migration of pollutants to underground waters and the assessment of susceptibility of the aquifers to pollution of agricultural origin in the lowland basin of upper Wilga river. Resulting from classification, performed with application of methods of numerical taxonomy, four types (typological classes) were distinguished as to the conditions of pollutant migration to groundwater. These types correspond to, respectively, the least advantageous, moderate, advantageous and highly advantageous conditions for migration of pollutants to groundwater. The results obtained were compared to the results of chemical analyses of groundwater, carried out in the selected locations of the basin. High degree of agreement with PO₄⁻ measurements was observed. Significant local pollution level of the groundwater was noted in some locations. These pollutants are mainly of organic origin, resulting from the leaking septic tanks, or their lack altogether, the improper storage of manure, as well as the storage of faecal and livestock wastewater.

Opis:
The suscepcibility of the aquifers to pollution depends upon numerous factors, including hydrogeological conditions and the nature of polluting substances. The paper presents the procedure for the establishment of the optimum set of physically justified and uncorrelated diagnostic variables, describing the process of pollution transport through the zone of aeration to underground water. On the basis of the existing methods and models, as well as equations used to describe the process of transport of humidity and pollution in the soil, the set of six physically justified variables was selected, characterising the best the movement of pollutants in the aeration zone (in-field water capacity of soil, soil humidity at the point of persistent withering of plants, filtration coefficient, depth of the groundwater table level, root zone depth, terrain gradient). The variables, represented through the form of numerical maps, were identified within the grid of uniform cells overlaid on the catchment area. The study was carried out in the basin of upper Wilga- the right-hand tributary of Vistula, representing the conditions of the environment of the Middle Polish Lowlands. The matrices of spatial information, prepared in this manner, were reduced with the aid of the principal component analysis. Consequently, the original set of diagnostic variables was replaced by three new synthetic variables, not correlated among themselves (the principal components), namely the indicator of sorption conditions (associating filtration coefficient, in-field water capacity and humidity of persistent withering), the indicator of infiltration distance (linked with the depth to groundwater level and the thickness of the root zone), and the terrain slope indicator. The new iagnostic variables, established in this manner (the principal components) may be made use of in determination of susceptibility of the aquifers to pollution and in classification of the catchment area with respect to conditions for migration of substances to underground waters.

Opis:
Wetlands are important component of the natural environment. This work presents the characteristics of selected wetlands in the Gorce National Park. During the field studies physical and chemical characteristics of the wetlands were measured and plant species were indicated. On this basis, the wetlands have been classified on the hydrological, trophic and peat bogs criteria. The study shows a great wetlands diversity in the small area of the National Park. Peat bogs and associated wetlands in the Gorce Mountains are complex of multiple natural communities. The bogs are often small, dispersed, and hydrologic regimes are quite differentiated from site to site. Most often they are fed by seepage or springs, however some are associated with impoundment of surface waters. Some are permanently wet, some intermittently dry, and still others contain both wetter and dryer areas. Generally, they are underlain by wet organic or mucky mineral soils, which are very acidic, though a few can be relatively basic. Wetlands in the Gorce Mountains contain a very diverse mix of herbaceous and arborescent vegetation. Other types of mountain wetlands are dominated by herbaceous vegetation only. The composition of vegetation is dependent upon numerous factors including: hydrology, soils, geographic location, disturbance history, current land use activities, and other factors. In fact, the hydrology and current land use of particular sites may be the most important factors that determine the current vegetation composition and structure of the mountain bogs. Human activities such as sheep grazing play a major role in the current vegetation makeup of the wetlands. For some, natural hydrologic factors result in what appears to be a relatively stable plant community dominated by sphagnum. Others seem to be more subject to natural successional processes that may, over time, shift the communities from open, herbaceous dominated areas towards more arborescent communities. The conditions of the Gorce wetlands is quite diversified. Significant amounts of the mountain bog habitats have been transformed and degraded. Further surveys are required in order to gather more information on the distribution and status of the wetlands and their vegetation.

Opis:
W artykule dokonano analizy wyników obserwacji przebiegu zjawisk lodowych na Bugu, prowadzonych w latach 1903–1960 oraz 2001–2012 w przekrojach wodowskazowych Dorohusk, Włodawa, Frankopol i Wyszków. Ustalono, że czas trwania zjawisk lodowych uległ skróceniu. Wyraźne są fluktuacje czasu trwania zjawisk lodowych i zlodzenia rzeki związane przede wszystkim ze zróżnicowaniem warunków termicznych w sezonach zimowych. Artykuł jest wprowadzeniem do tematyki zjawisk lodowych występujących na rzekach we wschodniej części Polski, a także przyczynkiem do prowadzenia dalszych badań związanych ze zlodzeniem rzek oraz do poznawania procesów je kształtujących.
The article describes an analysis of observations of ice phenomena on the Bug River, conducted between 1903– 1960 and 2001–2012, on representative gauge stations – Dorohusk, Włodawa, Frankopol and Włodawa. It has been concluded that the length of the period of ice phenomena has decreased. Fluctuations of duration of ice phenomena and ice cover, which are related to differentiation of temperature conditions in winter season, are well-marked. The article is an introduction to the subject of ice phenomena on the rivers in eastern part of Poland, as well as, the cause to pursue further research related to the ice cover of rivers and to explore the processes shaping them.

Opis:
The purpose of this study was to obtain and prove the methods of catchment regionalization in case of annual maximum floods. Identification of Polish rivers was hold on the basis of regional frequency analyses including recognition of homogenous regions in their physical properties and river flow parameters. Results indicate the division on two regional groups: mountain and lowland catchments. Statistical tests prove the obtained regionalization and allow calculating the regional probability curves for these two catchment groups. Obtained results may be helpful in the analysis of floods in ungauged catchments and these where hydrological observations were held in a short period especially when dependency of the maximum probable flows in analysed catchments from their physico-geographical features was proved.
