Abstract:

Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has been designed that would be invisible during the summer months yet function effectively during wet periods in the winter. Brush fires during the dry summer months are inevitable in Los Angeles County and major floods generally follow the fires. The hydrologic characteristics of burned watersheds has been analyzed and the extreme floods resulting from the occurrence of historical storms following the brush fires are simulated by the Stanford Watershed Model.
