Description
Technical Specification
Media
This apparatus can be used to study seepage and groundwater flows after precipitation, sediment transport in courses of rivers in presence of flow obstacles. Variable precipitation density and areas and different groundwater supply and drain possibilities allow a wide variety of experiments.
The equipment contains a closed water circuit with storage tank and pump. Stainless steel tank with adjustable inclination provides the space for performing the experiment. A precipitation device equipped with a timer is provided to define the times of precipitation. It consists of two groups of four nozzles. Water can flow in (groundwater) or out (drainage) via two chambers on the side. The experiment tank is separated from the chambers by fine mesh screens. To study the lowering of groundwater, two wells with open seam tubes are available. By means of a small weir in the supply and drain, a course of a river can be generated. Water supply and water drain can be opened and closed, thus allowing a wide variety of experimental conditions. In addition, three different models make it possible to study the flow around obstacles and the resulting sediment transport in the river bed.
19 tube manometers are installed at the bottom of the tank to detect groundwater level. Two flow meters with different measuring ranges indicate the supply to the experiment tank. A measuring tank at the drain contains a measuring weir for determining the water level and a force sensor for determining the amount of sediment.
The measured values are indicated at the apparatus. At the same time, the measured values can also be transmitted directly to a PC through and optional data acquisition software.
