ABSTRACT

Nowadays, after intervals of time without rainfall, heavy rain with very high flow rates in very short time are increasingly more often. If extreme rainfall events, storm sewer networks can not take storm water flows, which frequently occurs with flood damage large, often with loss of life. Duet o the fact that rainwater flows to the emissaries in time, the water table drops. Analyzing the frequency of extreme phenomena rainfall and using climate scenarios we can adapt technical regulations related to sizing collectors drainage, so the excess rainfall rates can be collected and stored in underground tanks and used for services utilities, agriculture or infiltrated into the ground. Incidentally land development has damaged the ground in most large cities, such water return to nature is affected by rainwater. In this paper we present solutions to prevent floods and to retain as much water in the ground as we can, in order to avoid droughts. Some of these solutions are the result of interdisciplinary cooperation with architects and roads and bridges engineers.
