Continuous Sediment transfer is successfully being applied e.g. at Olsberg Reservoir of operator RWE since 2011. An automated vessel provides year round sediment transfer, except during ice coverage. Over time the vessel strikes the complete reservoir ground to transfer incoming sediment which deposited on the reservoirs floor. The sucked sediment is pumped to the aligned hydro power plant where the sediment is dropped in front of the turbine inlet and transferred through the turbine to the downstream river. The turbine ensures a good mixing with the outflow. Turbine components are not affected at the given sediment ratio.<br />

A scaling instrument aboard the vessel allows for automatically adjusting a sediment transfer volume which suits to the actual plant/reservoir outflow and downstream compatibility. Transfer capacity at this application is up to 20 t/day, depending on the reservoirs outflow. The downstream river as well as the reservoir itself experienced a significant increase in ecological condition assessment within only weeks.<br />
