Nitrate Runoff Contributing From The Agriculturally Intensive San Joaquin River Watershed To Bay-Delta In California, Ruoyu Wang

Nitrogen loading from agricultural landscapes can trigger a cascade of detrimental e#11;ects on
aquatic ecosystems. Recently, the spread of aquatic weed infestations (Eichhornia crassipes, Egeria densa,
Ludwigia spp., and Onagraceae) in the Sacramento-San Joaquin Delta of northern California has raised
concerns, and nitrogen loading from California’s intensive farming regions is considered as one of
the major contributors. In this study, we employed the Soil andWater Assessment Tool (SWAT) to
simulate nitrogen exports from the agriculturally intensive San Joaquin River watershed to the Delta.
The alternate tile drainage routine in SWAT was tested against monitoring data in the tile-drained area
