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
