This paper presents a method to evaluate the hydrologic inconsistencies in terrain represented by digital elevation model. The method compares the drainage network automatically obtained from the terrain with a reference network. The differences obtained are quantified to determine the difference between the two networks. Basically, the network evaluation consists in comparing the corresponding rivers to compute the differences in the river length, direction, mouth, etc. The rivers correspondence is determined based on the otto codification which classifies the rivers using numeric codes based on some characteristics such as the drainage area, the river length, etc.Pages: 5225-523
