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

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 systemAlcamo 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)
• Multiple processes important at small scale• Societal implications and couplings at large scale
Simulation is key to spanning scales, transferability
• Climate change, land use change, water sustainability….

Ground Water Surface Water
• 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, 2004Anyah et al., 2008; Fan and Miguez-Macho, 2010]
• Water balance– Basins as importer/exporter?
[Toth, 1963; Schaller and Fan, 2009]
• Water quality– Flow paths, redox, residence time?
[Nolan et al., 2006; Shabaga and Hill, 2011; Carle et al. 2006; Sudicky, 2008; Kollet and Maxwell, 2008]
• Flooding– Depth of water table?
[Jourde et al. 2007; Finch et al. 2004; Kreibich andThieken, 2008]
Effect of soil moisture on cloud development
Shallow gw and atm boundary layer
Groundwater exchange
Nitrate in gw risk Flow paths and travel times
U.S. wetlands
Standard climate models
subsidence
