Analysis of the effect of drainage systems for water catchment system
NOCAROVÁ, Hana
In this diploma thesis I follow my bachelor thesis and generally deal with drainage systems and their influence on a water regime of a river basin. In the theoretical part, I describe issues associated with the drainage systems, whether their impact on the landscape or generally how they affect the water regime. Further I explain the water runoff in the landscape from its sorting and description of various runoff types up to the methods of its separation. Basic methods of the separation are described here, as well as separation with the use of digital filters. In the last part, these methods are used for separations of the runoff at selected river basins which are described in detail in the chapter named "material". For further comparison and results, the calculation of the runoff coefficient, analysis of precipitation and runoff events and analysis of subsidence branches were used. The chapter "results and discussion" where all results of this thesis are explained has been placed at the end.
Influence of drainage systems in the basin water regime
NOCAROVÁ, Hana
In this thesis I generally address draining systems and their influences on the water regime of a river basin. In the first part I describe the history from ancient times to the present, development in the world and in the Czech Republic at the range from 2000 years before Christ to the current systems. The thesis also explains basic terms, such as the content of agricultural ameliorations, terms relating to dewatering, purposes and division of draining systems, methods of dewatering actions, effects of water-logging and their consequences. At the end the thesis describes the impacts of building drains for draining off, dewatering and floods and the impact on the environment. The objective of the thesis is to describe the impacts and influences of drainage on the water regime of a river basin and the associated problems.
