I am Sachin Kumar
M.Tech student

My thesis topic is hydrological modelling in which i want do rainfall-runoff modelling and also water planning of river basin, hence I want to know that what is the minimum requirement of the data and which type of the data (daily or monthly) is required for rainfall-runoff modelling. I want to know the process of calibration and validation of WEAP model.

Dear Sachin,
