Document Summary
Gg101 week 9 lecture 2: water balance. Precipitation: measure using rain gauges, lysimeter, potential evapotranspiration (pe) latitudinal pattern, as we move northward we have less potential evapotranspiration, where there is a soil moisture deficit. Withdrawing water faster than receiving it: plot a soil water balance (fig 9. 10) Allows us to see how much moisture we are utilizing and when the recharge to the soils occur. Recharge: soil moisture budgets (fig 9. 10) Slope hydrology and groundwater (chapter 9 and 14 pages 234-236, 246-254, 447-449) Slope hydrology: fig 9. 2, p precipitation infiltrates ground. Some moisture going to evaporate from tree canopy - evapotransporation. Moisture can run off the surface directly (of) Percolation can happen - water moving down into the soil itself. Th can happen - lateral movement of water, forced to migrate laterally down slope. Some will percolate down to the water table. 4 routes water can take to get to the channel.
