1. FIRST REPORT TEAM 1: ANA CAROLINE PITZER JACOB JAIME TORRICO ACHA JONATAN ROBERTO VANESA LUCANA BARRAL TEAM 1 STUDY OF THE DRAINAGE NETWORK OF AN URBAN CATCHMENT LA RIERETA, SANT BOI DE LLOBREGAT SPAIN Thursday, july 14th 2011

2. 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

3. Basin Characterists Urban basin 16,07 ha Highly impervious area TEAM 1

4. 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 TEAM 1

5. DEFINITION AND INPUT OF HYDROLOGICAL PARAMETERS Variables % Slope = Terrain % Imperv = 90 % Zero- Imperv = 50 Drying Time= 0.3 N-Imperv = 0.017 N-Perv = 0.025 TEAM 1 Ven T. Chow

6. Determination of Width"W" TEAM 1 EQUATIONS S k = (A 2 – A 1 ) / A W = (2 – S k ) * l
