This book, first published in 1984, deals authoritatively with the nature and management of slope failures and sediment movement and their impact on the hazardous landscape of Los Angeles county. Bringing together for the first time a wide range of information derived from field observations, interviews, manuscript records, local agency reports and published sources, the book presents an analysis of the ways in which a rapidly developing metropolis has come to terms with complex geomorphological hazards. In particular, the events accompanying the major storms of 1914, 1934, 1969 and 1978 are reconstructed in detail.
