Ground Water Flow Apparatus

The Present apparatus is used for three dimensional investigations of ground water flows. The apparatus consists of a tank in which sand can be filled, and various models such as cylindrical and rectangular rings can be placed on the sand bed. The front wall of the tank is transparent for the visualization of various processes. The tank consists of two horizontal perforated tubes connected to supply line via two valves and have the provision to be operated separately via valves. The tank also have two open seam tubes which acts as wells for the investigations of various extractions and these walls have the provision to be activated separately via valves. Different models are provided for the study of excavation pits. At the bottom of the tank there are 19 tappings in the base of the tank arranged in a cruciform configuration and are connected to a multi-tube piezometer on the side of the tank. These indicate the profile of the water table in the sand.
