Transient drainage processes in storage reservoirs: Demonstration of the function of a rainwater retention basin and a storage lake:Features, investigation of transient drainage processes in storage reservoirs, simulation of rainwater retention basin and storage lakes, transparent surge chamber for observing oscillations after a water hammer, software for displaying the water levels. Learning objectives/experiments,  demonstrating transient drainage processes in two rainwater retention basins located one behind the other, demonstrating transient drainage processes in two storage lakes located one behind the other,recording oscillations of the water level in a surge chamber after water hammer ,recording and displaying water level fluctuations.

Specification:

• transient drainage processes in storage reservoirs

• functioning of a surge chamber

• "rainwater retention basin" experiment: basin A and basin B as short-term storage reservoirs, rectangular weir as gate

• "storage lakes" experiment: basin A and basin B are used as long-term storage reservoirs, rectangular weir as overfall weir

• "surge chamber" experiment: transparent pipe as surge chamber in drainage line of basin B

• gate in the drainage line for generating water hammer

• pressure sensors at both basins and the surge chamber capture the water level fluctuations

• representation of the variation in the water levels with software

• software for data acquisition via USB under Windows 8.1, 10. Technical data, Basin A: LxWxH: 900x900x300mm,material: stainless steel, rectangular weir according to Rehbock, adjustable, as gate, gate opening: 0...200mm, as weir, weir height: 0...200mm, overflowed width:
