Panorama of the Experiment Hall

The Experiment Hall is mainly composed of four parts: the test hall, the subsidiary building, the outdoor test field and the water treatment facility. It covers an area of 7455 m², of which the indoor building area is 4655 m² and the outdoor test field is 2800 m². It mainly consists of six test areas: indoor small watershed and urban hydrological test area, indoor variable slope water and sand process test area, indoor slope thin-layer water flow process test area, outdoor plain area binary water cycle test area, outm2door fixed slope water and soil conservation test area, and water resources comprehensive lab.

The Experiment Hall has more than 150 sets of instruments and equipment of 67 categories, including artificial rainfall simulation systems; groundwater level control equipment in test areas; test simulation, monitoring, control, and physical and chemical analysis instruments such as laser particle size analyzers, liquid water isotope analyzers, and continuous flow analyzers; as well as test auxiliary equipment for the purification and reuse of experimental waste water, etc., with a total value of more than 16 million yuan.
