Opis:: Rainfall in the Lake Tana basin is highly seasonal and the base flow contribution is also low resulting in the need for reservoirs to meet the agricultural demand during the dry season. Water demand competition is increasing because of intense agricultural production. The objective of this study is to develop water balance models. The Mike Basin model has been selected for water allocation modelling and identifying potential changes needed to the existing water allocation scheme to reduce the stress due to increased water demand. The study considers baseline and future development scenarios. The construction of new dams results in two competing effects with respect to evaporation loss. The first effect is increased evaporation from new reservoirs, while the other is reduced evaporation from the Lake Tana as a result of a decreased surface area of the lake and reduced inflow of water to the lake. Once a dam is built, there will be an additional free water surface area and more evaporation loss. In dry months from January to May, the irrigation water demand deficit is up to 16 Mm3. It is caused by reservoirs built in the basin, which reduce the inflow to the Lake Tana. The inflow varies between wet and dry months, and there is more water flow in wet months (July, August and September) and reduced flow in dry months because of the regulatory effects produced by the reservoirs.

Opis:: MIKE SHE software was used to estimate recharge into the aquifers of Ogun and Oshun Basins. Abeokuta within the Ogun Basin and Oshogbo in the Oshun Basin are sub-divided vertically into two components: atmosphere, and unsaturated zone. The atmosphere zone comprises of rainfall and potential evapotranspiration, while the unsaturated zones, comprises of the Basement Complex and Sedimentary rock. Daily records from two rainfall stations, Oshogbo station (2008–2011) and Abeokuta station (2010–2014) water years were obtained for simulation of groundwater recharge processes using MIKE SHE model. The simulation results showed that daily groundwater recharge is influenced by rainfall and ranges from 0 mm∙day^–1 in January when there was an insufficient rainfall in the two stations to 10.89 mm∙day^–1 in Abeokuta and 29.85 mm∙day^–1 in Oshogbo in the month of August when the soils had attained field capacity. The study found out that there are more daily groundwater recharge in Oshun basin compared to that of Ogun basin. This was alluded to more rain-fall and less evapotranspiration recorded at Oshun basin as compared to Ogun basin coupled with the sedimentary soil which allows more movement of water into the aquifer of the basin. It is recommended MIKE SHE model should be used to estimate recharge in other basins in Nigeria and Africa for quick and effective daily recharge calculations to permit better and scientific decision making in these areas.

Opis:: W artykule przedstawiono metodykę wyznaczania stref zalewowych na przykładzie górnej części zlewni rzeki Kłodnicy. Na obszarze tym prowadzi się wieloletnią działalność wydobywczą w kopalniach węgla kamiennego, co doprowadziło do osiadań powierzchni terenu, utworzenia zalewisk w nieckach osiadania, zaburzeń grawitacyjnego spływu wód i w konsekwencji do zwiększenia zagrożenia powodziowego w zlewni. Do określenia wzajemnego oddziaływania rzeki i terenów zalewowych wykorzystano oprogramowanie Duńskiego Instytutu Hydrauliki (DHI) – Mike FLOOD. Pakiet MIKE FLOOD składa się z MIKE 11, umożliwiającego opracowanie modelu jednowymiarowego oraz MIKE 21, który służył do opracowania modelu dwuwymiarowego. Wykonano obliczenia modelowe dla fali hipotetycznej o kulminacji odpowiadającej przepływowi o prawdopodobieństwie przewyższenia p = 0,2%. W efekcie przeprowadzonych obliczeń określono potencjalne miejsca wystąpienia terenów zalewowych w zlewni.
This paper presents the methodology of determining flood hazard zones illustrated with the example of the upper part of Kłodnica river basin. This is the area where mining activities in coal mines are conducted what have led to ground subsidence, formation of ponds in subsidence troughs, disturbance of gravitational flow of water, resulting in consequence in higher flood hazard within the river basin. The interactions between the river and the floodplains were studied with the help of MIKE FLOOD by DHI computer software. MIKE FLOOD package contains MIKE 11 tool which enables to create a one-dimensional model and MIKE 21 tool which was used to prepare a two-dimensional model. Model calculations were made for a hypothetical flood-wave with its culmination corresponding to a flow of exceedance probability p = 0,2%. As a result of these calculations potential flooded areas within the river basin were determined.
