Simulating DBP Precursor Transport in Sacramento Delta

Document Type: Proceeding Paper

Part of: North American Water and Environment Congress & Destructive Water

Abstract:

Fate and movement of disinfection by-product organic precursors in California's Sacramento-San Joaquin Delta was simulated for a 365-thy period with a hydrodynamics and transport model using historically-observed tidal, inflow and water quality boundary conditions. Predicted transport of dissolved organic carbon and ultraviolet absorbance at 254 nm compare favorably with observed data. A trihalomethane (THM) predictor developed in a companion paper was applied to compute formation potential concentrations at the diversion to California's State Water Project throughout the simulation period. THM predictions matched very well with limited available data.
