| Lessons from other similar projects
tell us that dam proponents
have suffered from: |
| AN INABILITY TO ACCURATELY ANALYSE HYDROLOGY; |
| ASSUMPTION OF UNCHANGING CLIMATOLOGY; |
| UNDERESTIMATION OF FLOOD PEAKS; |
| FAILURE TO CARRY OUT COMPREHENSIVE RISK ASSESSMENTS |
| DISCOUNTING OF RESERVOIR-INDUCED SEISMICITY |
| UNDERESTIMATION OF RISK OF CATASTROPHIC LANDSLIDING; |
| FAILURE TO ASSESS RISKS OF SABOTAGE OR WAR; |
| FAILURE TO ASSESS RISKS DUE TO OPERATIONAL ERRORS; |
| UNDERESTIMATION OF RATES OF RESERVOIR SILTATION; |
| DISCOUNTING OF EFFECTS ON RIVER BED AND BANK EROSION DOWNSTREAM; |
| IGNORING EFFECTS ON SEDIMENT SUPPLY TO DOWNSTREAM ESTUARIES AND COAST; |
| DISCOUNTING ANOXIC POLLUTION IN RESERVOIR AND DOWNSTREAM; |
| IGNORING EFFECTS OF HYDROLOGY CHANGES ON WATER QUALITY AND DRINKING WATER DOWNSTREAM; |
| FAILURE TO TAKE INTO ACCOUNT AGING OF DAM STRUCTURES; FAILURE TO DESIGN FOR DECOMMISSIONING OF THE DAM; AND |
| AN ASSUMPTION OF 'PERFECT' OPERATION THROUGHOUT LIFE OF THE DAM. |
