Because of the complexities of the hydrological cycle, the components of hydrology are typically separated and measured.
SWHL can install and maintain instrumentation, and provide interpretations to measure all components of the hydrological cycle, using scientific standards equivalent to the U.S. Geological Survey.
Components of the hydrological cycle and methods to quantify include:
-Weir, flume, open-channel gaging station
-Wells are small "windows" into the aquifer
-Water table defined by water levels in wells
-Water from springs can come from many miles away
-Tracers can be used to determine recharge areas
and discharge areas
-Raingage, snow gage, atmospheric precipitation sampler
-Pollution from hundreds or thousands of miles away can
be deposited in precipitation
-1999-current drought in Southwest US is similar to when
Ancestral Puebloans expierienced drought during 1100-1250.
-Historical satellite images reveal human's impacts on hydrology
-Early groundwater models used electrical resistors to simulate groundwater flow
-Early laboratory scale models were used for streams and estuaries
-Computer models are now used to simulate groundwater, streams,
lakes, estuaries, oceans, weather, climate, and atmospheric transport
