CAMPO, Alicia María; ALDALUR, Nélida Beatriz e FERNANDEZ, Sandra Noemí. Fluvial morphometry applied to an urban watershed in Ingeniero White, República Argentina. Invest. Geog [online]. 2012, n.77, pp. 7-17. ISSN 0188-4611.
The fluvial morphometry studies several variables that characterize the form of a drainage basin. The aim of this paper is to apply the natural watershed morphometric method to an urban watershed. The study area (6 km2) drains its waters into the waterfront and includes the town of Ingeniero White, República Argentina. Hierarchical organization of the drainage network was done. Three sub-basins that have low-gradient flood events, most dangerous extreme rainfall, were identified. The length relationship values showed greater concentration of power in event of major avenues. The elongation relationship values showed that one of the sub-basins is circular and has more speed in the avenues of runoff. The two elongated basins have greater delay in the avenues. The increased flow of the study area flows through the basin that has the largest number of order and the largest area. The other two basins are subject to increasing surface snapshot and immediate response. The slope and area values applied to hydrologic and hydraulic models determined the section of the ducts and channels. The calculated flow for the area drained was 22.41 m3/s.
