Abstract:

The research in urban hydrology in Switzerland does not result from a national organized and planned will, to solve hydrological problems (quantity and quality) due to urbanization. In that case, we understand by urban hydrology the study of the runoff directly related with the precipitations, excluding the study of domestic and industrial waters. The urban hydrology is not only studied for cities. In fact, if the main urbanization's factor is the soil's imperviousness, then, there is urbanization in the rural zones brought about by the simple fact of a fast evolution in the cultural practices and of a high density in the construction of rural roads and works against erosion. Due to the scale of Switzerland, which is a very small country, the study of the small rural watersheds presents a very great analogy with the study of the urban watersheds.
