DATA LIMITED REGIONS AND UNIQUE CHALLENGES-PMP ESTIMATION PRACTICES AND METEOROLOGICAL PARAMETER DEVELOPMENT FOR MINE TAILINGS DAMS

摘要

AWA utilized the storm-based approach to development PMP values and other meteorological data for two unique mine locations, one in Papua, Indonesia and the other in the high mountains of north central Peru. Data supplied by the client/mining companies, local governmental entities, internal AWA database, and remote sensing observations was investigated to develop the information needed to calculate the results. PMP results and annual exceedance probability of precipitation accumulations were developed. Changes in climate were included in the analysis by utilizing data from the entire period of record (50-100 years) and applying appropriate storm adjustments to derive the final PMP values. Each of these studies demonstrated that development of accurate and scientifically defensible PMP depths and other meteorological data are possible even in the most remote locations in the world. This is achieved through coordination and communication with the mine operations personnel and AWA experience and knowledge.
