Management of small retention ponds and their impact on flood hazard prevention in the Slovenske Gorice Hills

Abstract

One of the methods of water resource management is to construct small retention ponds. Within the framework of the “Possible ecological control of flood hazard in the hilly regions of Hungary and Slovenia“ project the management of small ponds and their impact on flood prevention were studied in selected catchments. Data on pond management were gathered from interviews with pond owners. In a pilot study, we conducted an inventarisation and classification of all retention ponds. Primarily they were constructed for more specific use: fishing, irrigation, watering livestock. These functions have been gradually replaced by leisure-time activities, aesthetics, and tourism. Spring, stream and rainfall-fed ponds prevail in the pilot area and reduce the flood risk. Due to the increased variability of precipitation patterns ponds are also becoming an important measure to limit drought consequences at a local level.
