Hydromorphological and landscape valorization of the Poprad river valley. The paper presents the results of hydromorphological and landscape valorization. The research was carried out in the Valley of the Poprad River, in the section from Piwniczna-Zdrój to Rytro (Małopolska voivodship). The hydromorphological valorization was made using the method of the evaluation of hydromorphological quality of the river. ECOVAST method was used for landscape valorization. On the basis of the research, Authors concluded that the research area is characterized by considerable hydromorphological variability, in particular in relation to the floodplains terraces and their connectivity with the main channel of the river. At the same time the valley of the Poprad river is characterized by the landscape of regional significance, with a very large tourist potential.

Spatial distribution of bottom sediment deposits in water reservoirs at Zesławice: Spatial distributions of bottom sediment deposits in two small water reservoirs located on the River Dłubnia at Zesławice is presented in this paper. The distribution was elaborated according to Dendy's method on the basis of results of silting measurements performed in the 2005. Horizontal and vertical distribution of sediment deposits was shown as relation between the relative volume of deposited sediments (S_h/S) and relative storage capacity of the reservoir (V_h/V); the vertical distribution of sediment deposits was presented as relation between the relative volume of deposited sediments (S_v/S) and relative reservoir depth (D/D_m). On the basis of performed analysis of horizontal distributions of sediment deposits it was stated that in the main reservoir at Zesławice 58% of the sediment trapped in the reservoir was accumulated in the inflow (upstream part of the reservoir, whose relative volume is 0.25). In the inflow section of the assistant reservoir of relative storage capacity equal 0.22 only 29% of the sediment was deposited. Comparing curves of horizontal sediment deposits distribution in the main reservoir in its inflow part according to measurement data from the 2005 and 1986 i.e. from a comparable period of operation before desilting and building of an assistant reservoir it was stated that relative volumes of sediment trapped after desilting are over 40% higher than before desilting. In a comparable period of operation before desilting (measurement in the 1983) and after desilting (measurements in the 2005) i.e. after seventeen and sixteen years respectively in the main reservoir the accumulated sediments formed an isle - the value S_v/S equaling 0.09 for D/D_m equal 0 in consequence of a change of hydraulic conditions of water and sediment flow - due to a part of inflowing water of the River Dłubnia being directed to the assistant reservoir.

Cel pracy: W pracy podjęto próbę określania warunków przepływu rumowiska w systemie odwodnieniowym stopnia wodnego w Łączanach na Wiśle. W tym celu opracowano rozkład koncentracji rumowiska unoszonego w przekrojach poprzecznych rowów systemu odwadniającego, opracowano profile...
