Water Resources

CHRS activities in water resources mainly focus on the fresh water quantity analysis in California. California has a unique situation in that its water supply regions and water demand regions are geographically dislocated such that approximately 75% of the precipitation happens in Northern California and around 65% of the demand comes from Central and Southern California. The importance of efficient water resources management is obvious. With regard to the characteristics of California’s water supply and demand, several water transferring projects -- including federal, state water, and local -- have been built to store, convey, and deliver fresh water to users.

The Federal, State and Local Projects in California.


Our activities include

  1. Global optimization algorithm development with the purpose of producing optimal water transferring strategies for the complex reservoir-system in California [Fig 1 & 2]
  2. Reservoir modelling and release forecasts using data-mining techniques for water resources planning
  3. Retrieving Cloud-free snow coverage information from remote sensing data [Fig 3]
  4. Evapotranspiration estimation considering the application of irrigation water in the Central Valley area of California [Fig 4]
  5. Object-based (event-based) precipitation database development (PERSIANN-CONNECT) for studying the impact of Atmospheric Rivers and extreme hydroclimate events
  6. Figure (1). Global Optimization Algorithms for rainfall-runoff model calibration.
