Abstract
In Chile, due to very steep mountainous areas near urban zones, it is almost
impossible to establish forecasting hydrological models with enough lead-time to
take non-structural measures to mitigate the effects of floods. During
construction of a highway inside the Mapocho River, a meteorological model
was performed to forecast the magnitude of rainfall and temperature three days
in advance, making possible an improvement in the lead-time of predictions.
This paper analyses the use of these results in a basin, near Santiago, the
country's capital city, which is characterized by having a variable snowfall area
depending on prevailing temperature. Two gage stations situated in tributaries,
located a certain distance upstream from the highway works, cont
