Water shed hydrology is determined by the state of soil surface. Different degrees of soil covering as well as soil exploitation can cause different processes of weather precipitation division into the watershed area. The anthropologic evolution due to the expansion of urban areas is having a significant impact on the hydrological responses within the catchment area. In addition to that, the change in precipitations intensity can affect the formation of flood discharge. Urbanization diminishes the capacity of soils to absorb precipitation, and as a consequence of that, unless proper “countermeasures are taken” throughout the catchment area, an increase in discharge volumes and a decrease in hydrological response time all over the area will ensue. Such a concurrence of events would lead to more frequent flood episodes for equal peak flows or, conversely, to higher flows and volumes for equal expected frequency. Land Use Planning can be therefore considered as an important tool in catchment hydrology.
