Water Resource Evaluation Flashcards
key components for water resource evaluation
P = ET + R + ΔS
P- precipitation
ET - evapotranspiration
R - Runoff
S - storage /change in storage
equipment for precipitation measurement
rain gauge
equipment for evapotranspiration measurement
lysimeter
______ determine storage
watershed area ; groundwater basin volume
water in the atmosphere returning to earth as liquid or solid
precipitation
most precipitation is a result of ________ over oceans
evapotranspiration
t or f: precipitation ahs extreme variability around the world
t
process converting water to water vapor
evapotranspiration
evaporation from soil surface and transpiration from plants
evapotranspiration
water flowing across land surface as streams, rivers, and drains after rain storm or melting snow
runoff
water flowing beneath land surface through sediments and rocks
subsurface (groundwater) runoff
t or f: runoff constitute both surface and ground waters
t
water collected in naturally occurring or man-made bodies along hydrologic cycle
water storage
storage bodies include:
lakes, reservoirs, wetlands, aquifers, ice caps
measurement approach for changes in surface water storage
