Landscape fragmentation for flood prevention: GIS and hydrological modelling approach assessing forested labscape.

Popis výsledku v původním jazyce

This paper assesses the influence of landscape patterns and intensity of land use on the retention capacity of small catchments (20-40 km2) in a forested landscape. A combination of geographical information systems with remote sensing and hydrological modelling was used to achieve the aim. An evaluation of the relationships between rainfall-runoff rates and some landscape pattern characteristics in three catchments led to the following findings: A reduction of landscape fragmentation between 1963 and 1997 to one tenth of the former level resulted in an increase in runoff coefficients in 1997, even though more than half of the area of arable land in 1963 had been turned into meadows by 1997.Higher presence of forest cover classes in a catchment did notresult in a higher retention capacity of the catchment compared to a less forested one. Catchments with a low degree of fragmentation and an extensive arable land class display the highest runoff coefficients among the three analysed catc
