Advanced Hydrology Apparatus (SMT-FM-47)
Investigation of precipitation-discharge
relationships, storage capacity of soils, seepage
flows, groundwater flows and sediment transport.
Closed water circuit.
Inclinable stainless steel experiment tank contains
12 measuring connections to detect groundwater
levels, transparent splash guard and screens for
separating the chambers.
2 wells with open seam tubes in the experiment
Precipitation device with 8 nozzles, adjustable.
SMT-FM-47 can be used to study seepage and groundwater flows after precipitation.
Furthermore, sediment transport in courses of rivers is also presented in the context of flow
obstacles. Variable precipitation density and areas and different groundwater supply and
drain possibilities allow a wide variety of experiments. SMT-FM-47 contains a closed water
circuit with storage tank and pump. The core element is a sand-filled, stainless steel
experiment tank with inclination adjustment. To study precipitation, a precipitation device is
available, which is equipped with a timer to define the times of precipitation. The
precipitation device 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. Different water levels 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. At the bottom of the experiment tank there are
measuring connections to detect groundwater levels, which are displayed on 12 tube
manometers. 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 trainer.
