Research Facilities:

Hydrology Laboratory
A 900 m2 hydrology laboratory has been established on the roof of George Vari Engineering and Computing Building. It is equipped with a weather station and a precipitation gauge, soil temperature and moisture sensors, water level meters, data loggers, and wireless modems for real time monitoring.

Hydraulic Laboratory
A hydraulic laboratory is being developed which includes hydraulic flume, vortex tank, and closed conduits. It will be equipped with magnetic flow meters, pressure transducers, velocity meters, etc.

Field Research Equipment

1. Automatic wastewater samplers
2. Telog water level meters
3. ISCO flow loggers
4. Tipping bucket rain gauges
