The proposed research aims to develop a process-based, watershed-scale numerical model that may be used to assess and predict mercury loading to streams and reservoirs. It will answer the following research questions: (1) Can a reliable and accurate process-based, watershed-scale mercury loading model be developed that will allow Reclamation to assess the feasibility and effectiveness of mercury management measures in its facilities such as reservoirs? (2) What are the key physical and biochemical processes, among many possibilities, that should be simulated more accurately than others for a reliable mercury delivery simulation? (3) Can we develop novel numerical methods to simulate mercury delivery more efficiently and reliably than existing models?
