HM 165

Basic Hydrology System

Technical Description

The HM 165 test stand facilitates basic experiments in the areas of percolation action on rain and in ground water flows. In particular, the permeability and storage capacity of soil can be very clearly observed. The experiments are performed in a stainless steel tank filled with sand. This tank is equipped with a sprinkler system so that rain can be simulated. In addition, there are 2 wells for lowering the ground water. Measuring points are fitted over the entire underside of the tank. The water levels in the sand bed can be read on a multiple tube manometer. The tank is equipped with several methods of filling and draining, the water supply is provided using a supply tank and a circulating pump.

Learning Objectives / Experiments

· Investigation of the effect of rainfall of varying duration on soil of varying saturation
· Investigation of percolation flows
· Investigation of capacity of soil to store water
· Investigation of the effects of wells on the flow of ground water

Features

· Closed loop test stand for investigating drainage and percolation processes in ground
· Fitted to laboratory trolley
· Experiment tank with adjustable tilt
· Large number of experiments possible
