Hydrological Modeling

2010-2011

Research Activities
DCDC II also supports Enrique Vivoni’s team from the School of Earth and Space Exploration and School of Sustainable Engineering to apply a distributed hydrological model of the Beaver Creek Basin in Arizona using the Triangulated Irregular Network (TIN)-based Real-time Integrated Basin Simulator (tRIBS). These model applications will help us detect and predict the consequences of land-use change and climate change on watershed hydrology. Activities to date include the development of full-scale model simulations of the Beaver Creek Basin for June through September 2006. Vivoni has processed model forcing for additional summer periods (2007–2009) and will examine that period in the future. Model calibration with respect to the observed streamflow at three gauging stations is underway and will add confidence to the model’s predictive ability when applied to future scenarios. These simulations use high-resolution parameter fields that describe the watershed topography, soils distribution, land cover/use, and meteorological forcing.
