3D view. HEC-RAS is simulation software used in computational fluid dynamics – specifically, to model the hydraulics of water flow through natural rivers and other channels.. The program was developed by the United States Army Corps of Engineers in order to manage the rivers, harbors, and other public works under their jurisdiction; it has found wide acceptance by many others since its ...
Hydrology in Practice has been described by CRC Press as "likely to be the course text for every undergraduate/MSc hydrology course in the UK". [3]The book has been reviewed by the Quarterly Journal of the Royal Meteorological Society, [4] the Journal of the American Water Resources Association, [5] the Hydrological Sciences Journal, [6] and the Journal of Hydrology, [7] along with being cited ...

A WRS, such as a river, an aquifer or a lake, must obey water balance. For example, the volume of water that goes into an aquifer must be equal to the amount that leaves it plus its change in storage. Under various drivers, such as, climate change, population increase, and bad management, water storage of many WRS is decreasing, say per decade ...
Note the location of critical flow, subcritical flow, and supercritical flow. The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation (See Bernoulli Principle), which takes into account pressure head, elevation head, and velocity head. (Note, energy and head are synonymous in Fluid Dynamics.
Each mathematical model included in the program is suitable in different environments and under different conditions. Making the correct choice requires knowledge of the watershed, the goals of the hydrologic study, and engineering judgement. HEC-HMS is a product of the Hydrologic Engineering Center within the U.S. Army Corps of Engineers.
The Journal of Hydrologic Engineering is a monthly engineering journal, first published by the American Society of Civil Engineers in 1996. [1] The journal provides information on the development of new hydrologic methods, theories, and applications to current engineering problems. It publishes papers on analytical, experimental, and numerical ...
In hydrology, there are two similar but distinct definitions in use for the word drawdown: . In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test.
