3. Changing surface hydraulic conductivity by a factor of 2: Does not significantly change evaporation or transpiration Does not significantly change total streamflow Does significantly change proportion of flow that occurs as base flow vs return flow. For smaller k larger proportion as return flow. Changing m by a factor of 10: Does significantly change evaporation and transpiration. For small m (rapid decay of k and less variability in saturation deficit) higher E, T. For large m (slow decay of k and more variability in saturation deficit) smaller E,T. Does significantly change total streamflow. For small m higher E, T is accompanied by higher streamflow. For large m lower E,T is accompanied by lower streamflow. Does significantly change proportion of flow that occurs as base flow vs return flow. For small m most of streamflow is from return flow. For large m all of stream flow is from baseflow. 2000-2003 Basin Totals
