The Role of Hydrotechnical Facilities in Flood Protection – Case Study: the Upper Basin and the Corridor of the Someşul Mic River

Abstract

The complex management of the catchment area proved to be the only effective way to cope with the extreme hydrologic phenomena and their effects. The watercourses controlled by artificial lakes have a quasi-total protection, water-flooding volumes being often fully retained in the man-made water accumulations. Therefore, both the Someşul Cald Valley and the Someşul Mic stream sector, downstream of Gilău have been protected from flooding, except for several outbursts of side tributaries of the Someşul Mic, with low socio-economic losses. In addition, the watercourses controlled by small dams with water adduction pipes have a minimal effect on maximum flow and especially during flooding periods. In the past, violent effects on the Someşul Rece catchment area were recorded in its meadow sector and in the locality bearing the same name, expressed by the destruction of several civilian targets and of the road that accompanies the river.
