Groundwater and Soil Water Resources Experimental Hall
The experimental hall of groundwater and soil water resources has an experimental space of 800m2 equipped with a long soil tank in a length of 16m and the height of 1.8m, a saturated and unsaturated soil tank in the length of 4m, height of 3, and width of 0.3m, and some other soil tanks for the determination of soil parameters and seepage experiment. The apparatus for the measurement of water content and the determination of soil parameters include Mini Trase, Time Domain Reflectometry, Gaulph meter, DL2e data logger, automatic monitoring and controlling system for the irrigation and drainage. Some soft wares are equipped in the lab for analysis of performance of irrigation and drainage system, management of agricultural water resources, simulation and analysis of groundwater flow and solute transport.
The experiments conducted in the hall include water and solute movement in soils, drainage by trench, pipe drainage, infiltration into and evaporation from soils, the affect of river stage on the soil water content under irrigation and drainage conditions, determination of soil parameters under saturated or unsaturated conditions, performance test of sprinkler or drip irrigation, experimental studies of water saving techniqu
