The New Zealand minerals sector proudly welcomes mine water specialists from around the globe to participate in the 2022 conference of the International Mine Water Association (IMWA 2022). The program will include the broad water management themes typical of an IMWA congress and will be showcasing world leading research and deployment of innovative passive treatment technologies, excellence in waste rock and tailings storage, world class surface water and groundwater prediction and monitoring along with spectacular geochemistry. The New Zealand minerals sector embraces operating in diverse natural conditions, a sensitive environment and with a watchful community of stakeholders.
Development of a Streamflow Model Incorporating Stochastic Daily Climate, Climate Change and El Nino/La Nina effects
Session: Climate Change | 3:20pm - 5:00pm | Christchurch Town Hall Room 2
Integrated Mine Water Management (MWM) is an essential component in selecting the planning strategy and operational management for a mine. A MWM tool simulates the uncertainty of predicting future climate and models the response of hydrological processes. For a copper-gold porphyry mine in the high Cordillera de Los Andes, SRK Consulting Inc. (SRK) developed a tool incorporating stochastic daily precipitation, snowpack, runoff, and temperature, including corrections for climate change and El Niño La Niña effects, into a single model. This record drove a numerical hydrologic lumped basin parameter runoff model, calibrated to the regional and local stream gauge records to produce streamflow under simulated climate conditions.
