Opis:: The study covered water resources of two mountain streams in the Polish Carpathians. These were the Biała Woda and Czarna Woda streams, the catchments of which are adjacent to each other. Water flows in both streams were measured during the hydrological years from 2006 to 2020. Next, water outflows from the catchments were calculated. The study aimed to determine differences in the water resources of those catchments in a very small mountainous area. The study showed quantitative similarity in water resources in the entire multi-annual period but at the same time large differences in shorter periods. Instantaneous and daily outflows showed the largest differences, but differences in annual outflows of up to 20% were also recorded. Therefore, hydrological data from operational cross-sections to assess water resources of neighbouring uncontrolled watercourses should cover multi-annual mean values. It was found that during periods of increased runoff (from melting snow or precipitation), the outflow from the Biała Woda catchment was much larger, while during rain-free periods, the outflow from the Czarna Woda catchment prevailed. All short-term flood like outflows were at least several tens of per cent higher in the Biała Woda catchment. The higher retention capacity of the Czarna Woda catchment can be attributed to the land use (mainly forest areas). The results can be used for modelling catchments of similar parameters and determining their retention capacity.

Opis:: The article describes the research on the retention capacity of two mountain catchments in the Polish Carpathian Mts. These are the catchments of the Czarna Woda and Biała Woda streams. These catchments are adjacent, have a similar area (about 11 km2 each), but are geographically diverse. Their geomorphology, hydrographic network, soil water permeability and land use were analyzed. The Czarna Woda catchment is a forest catchment, and the Biała Woda catchment is a forest and agricultural catchment with pasture areas. The geographical analysis of the catchment showed that the Czarna Woda catchment most likely has greater retention capacity. Theoretical analyzes were verified on the basis of long-term measurements of flows in both streams. Outflows were calculated for the entire study period (2006-2022), as well as annual, monthly and daily outflows. The measurements were carried out using the overflow method in permanent measurement cross-sections. The total outflow from both catchments was simi-lar, so they had similar water resources. In particular years, months and days, outflow often differed significantly between catchments. It was found that during the periods of increased water runoff (from precipitation, from snowmelt) the outflow from the Biała Woda catchment was higher, while in the periods without precipitation the outflow from the Czarna Woda catchment prevailed. Short-term flood outflows were at least several dozen percent higher in the Biała Woda catchment. The measurement data confirmed that water was better retained in the Czarna Woda catchment and the outflow was slower. Water retention processes in the Czarna Woda catchment allowed to maintain minimum outflows at a level several times higher than in the Biała Woda catchment. The studies have shown that in a very small mountain area there can be a large variation in outflow in individual streams. Retention capacity of the catchment depends on environmental conditions and human activity.

Opis:: W artykule omówiono problemy rolnictwa górskiego, które powinny być uwzględniane w działalności informacyjno-szkoleniowej służb doradztwa rolniczego. Są one związane z ochroną powstających w zlewniach górskich zasobów wodnych. Zwrócono uwagę na konieczność transformacji struktury użytkowania ziemi, w tym utrzymywania trwałych użytków zielonych. Wspomniano o metodach zapobiegania spływowi powierzchniowemu i jednocześnie erozji, a także warunkach stosowania nawozów i środków ochrony roślin. Potrzebę rozpowszechniania wiedzy uzasadniono na przykładzie obszaru zlewni kaskady Soły. Prowadzenie gospodarstw zgodnie z wymogami ochrony środowiska jest obecnie warunkiem uzyskiwania dopłat do działalności rolniczej.
This article reviews the problems of mountain farming, which should be included in the information and training activity of the agricultural advisory services. They are related to the protection of water resources in mountain catchments. The attention has been paid to the need of transformation of the structure of land use, including the maintenance of the land permanent meadow-pasture. The methods of preventing surface runoff and erosion, as well as conditions of fertilizers application and plant protection products, were mentioned. The necessity for popularization of the knowledge was proved on the example of the area of the Soła River dam cascade. Running a farm in accordance with environmental protection requirements is now a condition for obtaining subsidies for agricultural activities.
