Description
In the face of increasing demands from urban areas, irrigation and environmental concerns, water management in semi-arid areas is difficult. In the Southwestern US, a critical unbalance between water supply and demand is prompting water conflicts between multiple water stakeholders. The NSF STC Center for the Sustainability of semi-Arid Hydrology and Riparian Areas (SAHRA) is a multi-institutional effort to accelerate the state of scientific knowledge and water management in semi-arid areas. In light of climate variations, the scientific community has an urgent need to deliver predictions of potential hydrologic stress in regional semi-arid basins. The primary goal of this proposal is to provide SAHRA the capability to perform fine-resolution hydrologic simulations with an efficient distributed model that captures spatial heterogeneities in basin properties and meteorological forcing. The project focuses on coupled rainfall-runoff modeling in order to : (a) represent the spatial-temporal distribution of surface-subsurface processes at multiple scales over the Rio Grande, and (b) simulate the effect of climate and land-use change. The TIN-based Real-time Integrated Basin Simulator is the proposed model to account for the spatial variability of the rainfall-runoff process. Through integration into a high performance computing environment, the proposed model will improve the surface hydrology in the Los Alamos National Laboratory fine-resolution model. In addition, the triangulated irregular network model will allow computational savings as compared to grid-based models through the multi-resolution, multi-scale domain representation.
