Combined dimensional drainage model and surface model (1D-1D)

It is possible to carry out very accurate risk identification by combining a surface model with a drainage model. When performing a digital analysis of surface flow patterns, it is possible to reduce the surface area so that it consists of a number of depressions and channels corresponding to the calculation methods implemented in dynamic 1D drainage models. This makes it possible to combine the surface model directly with the drainage model, providing a 1D-1D system.
