The evaluation of the hydromorphological structure of surface water is made in two steps: First the method for the surface water development ability is applied. For this method the current structure of the surface water is analyzed for the different surface water sections. Constructing on the section-referred evaluation a total evaluation of the surface water development ability per surface water body takes place.
