Description :
Surface depression storage is an important factor in preventing runoff and erosion in agricultural fields. The most reliable way of estimating maximum depression storage (MDS) is generally estimated from roughness indices derived from 2D transects, but these MDS estimations have a high uncertainty. The most reliable way of estimating MDS is by simulating the filling of a digital elevation model (DEM) of the soil surface using an algorithm. The aim of this study was to produce 3D DEMs with correct storage characteristics, using a simulation model that uses common 2D field elevation measurements as input.
