8. Land Use/Land Cover

9. LULC Most: Row crops Pasture/Hay Grasslands Orchards/Vineyards Forests
Fertilizer

10. Watershed Exports and Storm Events
Calculate Runoff
* to be completed
Compare Runoff and Precipitation data
Storm Events and LULC
Possible increase N in estuary

11. Next year at UTMSI… Surface water samples Analyze water chemistry
Focus on Storm Events
Non-point source pollution

12. Questions??
