2. The Water Balance Model: typical for Cascadia Water Quantity Before 16.5” interflow (infiltration) 26” evapo- transpiration 0.2” runoff 65” rainfall yearly avg 22” groundwater (infiltration)

3. The Water Balance Model Water Quantity After 0” baseflow (infiltration) reduced evapo- transpiration 63” runoff 65” rainfall yearly avg 2” evapo- transpiration Reduced infiltration

4. Impervious Surfaces A Watershed Perspective

5. The Water Balance Model Water Quality Before Some sediment

6. The Water Balance Model Water Quality After Sediment (air particulates), dissolved pollutants (nitrogen, zinc), heavy metals, Feces, Temperature, other debris Sediment/turbidity, Hydrocarbons, Heavy metals, temp, feces, other chemicals Sediment/turbidity fertilizers, pesticides herbicides, feces, heavy metals
