  2. Community Hydrologic Modeling ProjectCHyMP • Objective: Advance hydrologic sciences by enabling community modeling. • 3 workshops • Scoping. 20+ participants; Academics, Fed. Agency, Private Sector March 2008 [Famiglietti et al., 2008]. • Blueprint. 50+ participants, March 2009 [Famiglietti et al., 2009]. • Implementation. 30+ participants, March 2011. [Famiglietti et al., in prep]. • Outcomes • Agree on importance • Recognize ongoing work • Identify next steps Status of the Community Hydrologic Modeling Project (CHyMP), Larry Murdoch, HIS User’s Conference, Logan, Utah; June 2011

  3. MotivationGrand Challenges in Hydrology • “The challenge is to predict changes in freshwater resources and the environment caused by floods, droughts, sedimentation, and contamination in a context of growing demand on water resources.” NRC Report (2001) • Predict changes in connections throughout the global fresh water system Alcamo et al (2008) • Predict • Effects of human activities and natural perturbations • Patterns and variability of processes affecting quantity and quality • Optimal management for sustainability of water resources WATERS Network. Minsker (2007) • Climate change, land use change, water sustainability…. • Multiple processes important at small scale • Societal implications and couplings at large scale • Simulation is key to spanning scales, transferability Status of the Community Hydrologic Modeling Project (CHyMP), Larry Murdoch, HIS User’s Conference, Logan, Utah; June 2011

  4. Ground Water Surface Water U.S. wetlands subsidence • Sustainability • gw-sw, a single resource [Winter, 1999] • Climate • How deep is water table? [Fan et al., 2007; Maxwell et al. 2007; Ek and Holstag, 2004 Anyah et al., 2008; Fan and Miguez-Macho, 2010] • Water balance • Basins as importer/exporter?
