Changes of water regime due to land use change
Buchtele, Josef ; Buchtelová, Marie ; Košková, Romana
Tendencies in water regime resulting from land-use change represent an important and actual subject for research on global scale as well as urgent problem from the local viewpoint.The assessment of deforestation, urbanisation and intense farming effects on flood regime on local or regional scale represent an important and integral part of such intentions and projects. Gradual deforestation, then overgrowing of deforested areas with grass or reforestation of some parts of catchments indicate that the change of vegetation cover did not occur as an abrupt change, but often even random phenomena took place, such as damage in woods inflicted by bark beetle, etc. In order to compare consequences of all these phenomena in different natural conditions simulations in relatively undisturbed areas, i.e. in the Šumava Mts in southern Bohemia were incorporated into the studies. The Vltava catchment down the river to Lenora village and Otava catchment down to Modrava are used for such comparisons.
