Resumen
Urban stormwater can be considered as potential water resources as well
as problems for the proper functioning of the manifold activities of the city,
resulting from inappropriate use and occupation of the soil, usually due to poor
planning of the occupation of the development areas, with little care for the
environmental aspects of the drainage of surface runoff.
As a basic premise, we must seek mechanisms to preserve the natural
flow in all stages of development of an urban area, preserving the soil infiltration
capacity in the scale of the urban area, comprising the mechanisms of natural
drainage, and noting preserving natural areas of dynamic water courses, both in
the main channel and in the secondary. They are challenges for a sustainable
urban development in a harmonious coexistence of modern developmental,
which are consistent with the authoritative economic environmental and social
quality.
Integrated studies involving the quantity and quality of rainwater are
absolutely necessary to achieve understanding and obtaining appropriate
technologies, involving both aspects of the drainage problems and aspects of
use of water when subjected to an adequate management of surface runoff , for
example, the accumulation of these reservoirs in detention with the possibility of
use for other purposes.
The purpose of this study aims to develop a computer model, adjusted to
prevailing conditions of an experimental urban watershed in order to enable the
implementation of management practices for water resources, hydrological
simulations of quantity and, in a preliminary way, the quality of stormwater that
flow to a pond located at the downstream end of the basin. To this end, we used
in parallel with the distributed model SWMM data raised the basin with the
highest possible resolution to allow the simulation of diffuse loads,
heterogeneous characteristics of the basin both in terms of hydrological and
hydraulic parameters on the use and occupation soil. The parallel work should
improve the degree of understanding of the phenomena simulated in the basin
as well as the activity of the calibration models, and this is supported by
monitoring data acquired during the duration of the project MAPLU (Urban
Stormwater Management) belonging to the network PROSAB (Research
Program in Basic Sanitation) in the years 2006 to 2008
