EARTH MOVEMENT AT BALDWIN HILLS RESERVOIR-CLOSURE

SOME OF THE MOST SIGNIFICANT LESSONS ARE LEARNED FROM DISASTERS. INVESTIGATORS OF FAILURES HAVE AN IMPORTANT OBLIGATION TO SHARE THEIR FINDINGS. DISCUSSIONS OF OTHER FAILURES WOULD HAVE BEEN WELCOME SUPPLEMENTS TO THE WRITERS' PAPER. RECENT CATASTROPHES AT MALPASSET AND VAIONT DAMS, AND THE EVENTS AT FONTENELLE AND HEBREB DAMS PROVIDE SOBER THOUGHT FOR THOSE WHO STRIVE TO IMPROVE THE PRACTICE OF ENGINEERING OF DAMS. IN RESPONSE TO MOUNTING PUBLIC CONCERN ABOUT SAFETY OF DAMS AND RESERVOIRS, THE STATE OF CALIFORNIA ENACTED LEGISLATION IN 1965 BROADENING REQUIREMENTS FOR SUPERVISION OF WATER STORAGE FACILITIES. RESPONSIBLE AGENCIES ARE CONDUCTING VIGOROUS PROGRAMS TO ASSURE THE SAFETY OF THEIR STRUCTURES. THERE IS A GROWING APPRECIATION OF THE VALUE OF CAREFUL WATCHING OF PERFORMANCE. OPERATING RESERVOIRS REQUIRE PROFESSIONAL ENGINEERING SCRUTINY THROUGH A SYSTEMATIC, PROGRAMMED EFFORT. CHANGES IN THE CONDITION OF A DAM CAN BE SUBTLE AND DIFFICULT TO DETECT, BUT IMPROVED INSTRUMENTATION AND MONITORING TECHNIQUES PROMISE EARLIER DISCOVERY OF DEFECTS. HEAVY EMPHASIS MUST BE PLACED UPON PERCEPTIVE DATA ANALYSIS-THE CORNERSTONE OF ANY EFFECTIVE SURVEILLANCE SYSTEM. /ARTICLE/ REFERENCES: ROBERT B. JANSEN, GORDON W. DUKLETH, BERNARD B.
