Rain Fall Hydrograph

The Rainfall Hydrograph Apparatus is designed to study the relationship between rainfall and surface runoff in a controlled environment. This compact unit simulates rainfall over a model catchment area, allowing observation and analysis of hydrograph development. It includes an adjustable rainfall simulator, a catchment tray with variable slope, and a calibrated tank to measure runoff. The system enables the study of rainfall intensity, catchment response, infiltration, lag time, peak flow, and baseflow separation. Complete with sensors or gauges for monitoring rainfall depth and runoff rate, this apparatus provides essential hands-on learning for hydrology and water resources engineering.
