Opis:: W pracy przedstawiono 4-letnie wyniki badań z lat 2002-2006 nad bilansem wodnym nawadnianego obiektu melioracyjnego. Badania prowadzono na obiekcie Wir, stanowiącym fragment doliny Wiązownicy, w gminie Potworów, w województwie mazowieckim. Pomiary składników bilansu wodnego: dopływu i odpływu powierzchniowego, opadów, retencji glebowej i powierzchniowej oraz wyniki obliczeń ewapotranspiracji, uzyskane na podstawie danych meteorologicznych i pomiarów plonowania użytków zielonych na obiekcie, umożliwiają oszacowanie dopływu gruntowego do doliny. Wyniki badań świadczą, że w małej dolinie rzecznej jest on bardzo zróżnicowany w poszczególnych latach i występuje głównie w pierwszym odroście traw.
Results of a 4 years long (2002-2006) study on water balance in an irrigated reclamation object are presented in this paper. Studies were carried out in the Wir object - part of the Wiązownica River valley, Potworów commune, Masovian Province. Measurements of water balance elements like surface in- and outflow, precipitation, soil and surface water retention and the results of calculation of evapotranspiration based on meteorological data and measured grassland yielding allowed for estimating groundwater input to the valley. Results of this study show that the groundwater input varies between years and occurs mainly during the first grass regrowth.

Opis:: The paper reports on a study of the impact of morphology and lithology of small catchments on episodic river channel development in the southern High Atlas Mountains in Morocco. A detailed analysis focused on three catchments of small wadis featuring different relief and lithology along the upper, middle and lower course of the Dades River. The fieldwork combined with an analysis of topographic and geological maps and of satellite images concluded that the development of the river valley and channel structures was related to the main stages in the development of the landform in this part of the High Atlas. The channel dynamics were found to be typical of arid mountains, which was particularly apparent within a denudational-and-fluvial zone that reached up to 3,000 m a.s.l. The dominant morphodynamic system of this zone was pluvio-gravitational where episodic heavy rainfall events triggered fast displacement of stone mantle covers down the slopes and into the river channels. An analysis of the deposition zones in the lower channel reaches and on alluvial fans at the confluence of the side valleys and the main valley leads to the conclusion that the main factor, which determines the channel morphology is the impact of debris flows and heavily loaded streams and rivers. The deposited material is then transported outside the mountain zone and deposited within broad river channels. The development of the river channels in the three catchments depends on their order, morphometric property, slope lithology and the amount of material received from the slopes.

Opis:: The paper refers to spatial diversity and lability of outflow from Flysh type drainage basins. It also shows dynamics of mean and high discharge by defining the trend, the variability index and the periodicity of the hydrological parameters mentioned. The research has been taken in the partial drainage basins located in the upper drainage basin of Skawica (the streams of Czatożanka, Marków Potok, Rybny Potok, Jaworzyna) and in the upper drainage basin of Czarna Orawa (Kiczorka) at the Babia Góra slopes. The analyzed two-year period (2012–2013) has been characterized comparing to the multiannual period of 1973–2014. The hydrological and meteorological data have been obtained due to monitoring of the hydrological environment of Babiogórski National Park. The database includes the data gained from The Institute of Meteorology and Water Management research. Poland is the one of the less water-rich European countries. The unit outflow is only 5.5 dm3·s-1·km-2 (Fall 1997). The water outflow is very space and time varied through the whole country. The outflow from drainage basins of Babia Góra area is one of the biggest in Poland (about 30 dm3·s-1·km-2). The outflow index (rate of outflow?) from Babia Góra area is 88% per annum, which distinguishes this area from the Beskidy Mountains. During the winter semester the outflow index is 12.7% and during the summer semester it is 70% (Łajczak).The outflow index and the seasonal lability of the outflow from the particular Babia Góra drainage basins are very varied which is the most noticeable between the northern and southern slopes located drainage basins, however the variety is also very clear to observe from the east to the west direction. The analyzed cycle were a general low-flow period including one thaw flood within this period (2012s) and several minor floods caused by severe rainfalls (2013s). The maximum unit outflow during the flood has been noticed in Czatożanka drainage basin and the minimum unit outflow has been noticed in Kiczorka drainage basin. The highest annual average unit outflow occurred within Marków Potok, and the lowest annual average unit outflow occurred within Czatożanka. The drainage basins located at the northern slopes of Babia Góra were characterized by big seasonal outflow fluctuation between winter and summer semesters. Only at the southern slopes in the Kiczorka drainage basin the outflow was not much varied comparing the particular semesters.
