Human impact on the hydrological regimen and fluvial processes of the River Wda
Summary: The Wda River drainage basin is characterised by relatively stable hydrological processes, water level and discharge. This natural annual discharge pattern is modified by varied land uses throughout the drainage basin and by the use of the River Wda for irrigation and hydropower. In the case of the land use, anthropopressure involves a retention of some of the water in the meadows during the vegetation period resulting in a lowering of water levels in watercourses. The utilisation of river water causes an increased intensity and degree of fluctuation of the water level of the River Wda downstream from the hydropower plant. In the past, this had an effect on channel processes, but with the recent reduction of human intervention in the water environment a trend towards re-naturalisation of the channel has been observed. This study showed that in order to maintain stable morphodynamic conditions in the river channel while utilising outwash plain rivers, there is a need to keep discharge fluctuation at a low level.
