Abstract: Rapid population growth and the concentration of almost 40% of the total population (1981 Census) in the narrow valleys of the northern mountain ranges, a tropical climate with a very intense wet season that last seven months on the average, has made the question of urban hydrology in Venezuela a very important one with the emphasis being on urban drainage rather then on hydrologic research. The initial investment needed for the major system of drainage has required an approach to urban drainage that puts forward its objectives and functions in order to prepare the conceptual design for the major drainage under the format of a master plan. This approach has been applied to new towns and expansions of existing ones, relating city planning to the drainage master plan and defining both preventive and corrective measures for more rational urban use of the relatively narrow plains that are subjected to flash floods or the wide river plains and deltas.
