Document Summary
Potential evaporation (pe): evaporation under unlimited supply of water such as a lake. Actual evaporation (ae): evaporation from a soil surface which is typically limited by moisture/water availability. Transpiration: the e(cid:448)apo(cid:396)atio(cid:374) of (cid:449)ate(cid:396) f(cid:396)o(cid:373) pla(cid:374)t"s (cid:449)ate(cid:396) (cid:449)he(cid:374) the(cid:455) ope(cid:374) thei(cid:396) sto(cid:373)ata to take i(cid:374) co2 for photosynthesis. Water flows from the roots to the leaves. Discharge (q): volume of water that flows past a gauging station in a unit time interval (m3/s). Baseflow: steady input of groundwater that sustains streamflow over long time periods. Stormflow: runoff of rainfall and snow melt that causes high discharge, lasting days to weeks. Watershed: a watershed, catchment area or drainage basin all refer to an area over which water falling on the surface will drain into a river or a lake. It is based on the topography of the area. Effective porosity: interconnected pores that control groundwater flow, ne.
