Abstract:

In southern California, the Tatum method and the Los Angeles County Flood Control District procedures have been widely used to estimation debris production rates. To evaluate the applicability of these procedures to other local areas, specifically to the northeast aspect of the Santa Ana Mountains, a study of the geology, soils, precipitation, vegetation and physiographic factors of the two areas was completed. Additionally, results from the Tatum and Los Angeles County procedures were compared with other techniques for estimating debris production to arrive at the best estimate of potential loading to three proposed debris basins.
