Abstract

The paper presents the results of sediment monitoring in a small experimental agricultural Rybárik basin near Považská Bystrica (Western Slovakia). In compare with rainfall-runoff events, during which suspended sediment concentrations increase with the flow, there is no significant relationship between discharge and suspended sediment concentrations measured during the base flow. These concentrations are considerably lower than those measured during rainfall-runoff events. It is clear, that the behaviour of suspended sediment in the small Rybárik basin is not only a function of flow energy conditions. Sediment transport rates are also a function of sediment availability. Based on suspended sediment concentrations and discharge values measured during the base flow for the hydrological year 1986/87 (1–3 day sampling interval) the annual value of suspended sediment load was calculated. The calculated load for the year 1986/87 is 2106 kg year-1 (17.6 t km-2 year-1) for the Rybárik basin. Due to missing data in the rest of the monitoring period, it was not possible to compute sediment load for other years. However, comparison of suspended sediment concentrations measured on infrequent sampling basis (7 day sampling interval approximately) over a period from April 2001 to October 2001 with concentrations measured for the same period in the year 1987 suggests weak changes in suspended sediment loads for the individual hydrological years.
