STUDY OF THE DRAINAGE NETWORK OF AN URBAN CATCHMENT
LA RIERETA, SANT BOI DE LLOBREGATSPAIN
Thursday, july 14th 2011
OBJECTIVES
• Discretization of the basin (physical parameters);• Determination of hydraulic parameters of the basin;•Determination of effective rainfall;•Calibration and validation of hydrological-hydraulic model of Riereta basin;•Modeling with the design rain and diagnosis of hydraulic operation according to the results;•Changes and/or alterations of drainage network in accordance with operational hydraulics criteria, maintaining the current network.
TEAM 1
Basin Characterists
•Urban basin•16,07 ha•Highly impervious area
TEAM 1
SUBCATCHMENTS DISCRETIZATION
•Generation of contour map•Obtaining coordinates and elevations (interpolation)•Location and delimitation of the basin
•Definition of the subcatchments•Obtaining lengths of pipes
