'Surface water
hydrology' describes the relation between rainfall and
surface runoff; this relationship is an important aspect of
water resources for
sewerage (
wastewater) or (
sewage),
drinking water, agriculture (
irrigation) environmental protection, and for
flood control.
Surface water hydrology relates to the dynamics of flow in surface water systems (
rivers,
canals,
streams,
lakes,
ponds,
wetlands,
marshes,
arroyos, etc.). This includes the field measurement of
flow (discharge) and subsurface water levels in
wells; the relationships between
groundwater and
surface water, the statistical variability at each setting, and then development of the levels of risk. Examples include
baseflow needs for instream flow, drought susceptibility, and flood levels.
In-depth analysis of surface water components of the hydrologic cycle: hydrometeorology, evaporation/transpiration,
rainfall-runoff relationships, open-channel flow, flood hydrology, and statistical and probabilistic methods in hydrology.
