ASSESSMENT OF SEDIMENT INPUT INTO THE MODRAC ACCUMULATION WITH DETERMINATION OF EROSION CHARACTERISTICS OF THE MODRAC ACCUMULATION CATCHMENT AREA
Determining the erosion characteristics of a catchment area is very important in managing the catchment area itself, as well as in managing water resources, especially if it is a multipurpose reservoir. Factors that determine the erosion process in a watercourse catchment area, or the sediment regime of a watercourse, could be divided into those that practically do not change or those that do not change significantly over a period of several years, and factors that are subject to change during the year, depending on meteorological and climatic changes over the catchment area. For preventive action and prevention of erosion, and thus flash floods, and filling of reservoirs, it is necessary to analyze and determine precisely the erosion coefficient of the catchment area. On the other hand, water resources management includes a number of activities such as planning, design, construction, management, maintenance, monitoring and control of constructed facilities, in order to assess and increase their efficiency. Accordingly, it is necessary to specifically plan all activities in relation to reservoirs as key facilities for managing the water regime of a catchment area and processes within the catchment area.
