Fig. 8. The unit hydrograph estimated from radar data and pluviographs.
Additionally, in order to obtain a methodology to determine the distributed parameter
hydrologic model in other watersheds, the experimental basin of the river Mixcoac and the
technique Distributed Unit Hydrograph (Clark, 1943) is used. The conceptual model
obtained (Fig. 9) is similar to Maidment model (Maidment, 1993). The model obtains the
isochrones to Mixcoac River Basin (Fig. 10), which is then used to estimate the outflow
hydrograph of the basin. The comparison between the observed and estimated with the
distributed hydrological model fed with precipitation data obtained from the radar is
showed in the figure 11.

(Source: Kull & Feldman, 1998).
