APPLICATION OF WASIM-ETH
APPLICATION OF WASIM-ETH
1. Technical Problem
Application of WASIM-ETH (Maule basin, Chile) using 100m * 100m grid
resolution (Richards Equation) is too slow for calibration.
Calibration and validation of WASIM-ETH using a 1000m * 1000m grid resolution.
Validation of the adaptability of the calibrated parameters on the final 100m * 100m
resolution WASIM run.

2. Technical Problem
One important inflow (sub-catchment) in the western part of the catchment
is missing.
Extension of the dgm in the western part of the basin to calculate the sub-basin.
Simulating the missing inflow by an external inflow of a smaller sub-basin in the
western part of the catchment
