Modelling of the Water Retention Capacity of the Landscape
Original language description
The most frequent natural hazards which have affected the area of the Czech Republic over the last decades have been floods. The floods arise as a result of the accelerated surface runoff from the land use segments which are caused by the increasingly higher occurrence of patches with low or even critically low retention ability. The number of extreme hydrological events has rapidly increased in the last hundred decades. The accrual of floods has been a consequence of increased runoff from the landscape, and this runoff has been caused by a decrease in flood storage capabilities. The areas with low flood control capability have increased more and more frequently in the watersheds because the diversity of the landscape has been reduced and the total ecological stability has been weakened. The key element for localization of patches with critically low rainfall retention is to determinate the current spatially specified surface runoff. These patches are predetermined for application of suitable arrangements aiming at increasing their retention ability. The proposed procedure for calculation of spatial specification surface runoff is based on a combination of specific functions of the geographic information system which is enabled by runoff curve number method. The formulated LOREP model represents an application of a solution using a methodical approach for the identification and localization of areas with low flood storage capability. This enables a comparison of the projected scenarios. The structured catalogue of non-technical measures in the landscape is a part of the model. The procedure of computation of territorial-specific surface runoff is based on a combination of specific functions in GIS as fuzzy sets, hydrological equations of the runoff curve number method and spatially distributed unit hydrographs.
