Infographic explaining the hierarchy of the United States hydrologic unit system. Originally a four-tier system divided into regions, sub-regions, accounting units, and cataloging units, each unit was assigned a unique Hydrologic Unit Code (HUC). As first implemented the system had 21 regions, 221 subregions, 378 accounting units, and 2,264 ...
The following outline is provided as an overview of and topical guide to hydrology: Hydrology – study of the movement, distribution, and quality of water on Earth and other planets, including the hydrologic cycle , water resources and environmental watershed sustainability.
Static level is the level of water in the well when no water is being removed from the well by pumping. [8] Water table is the upper level of the zone of saturation, an underground surface in which the soil or rock is permanently saturated with water. [9] Well yield is the volume of water per unit time that is produced by the well from pumping. [8]
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 ...
Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) ' water ' and -λογία () ' study of ') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources ...
A hydrological code or hydrologic unit code is a sequence of numbers or letters (a geocode) that identify a hydrological unit or feature, such as a river, river reach, lake, or area like a drainage basin (also called watershed in North America) or catchment.
A water resource region is the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units as part of the U.S. hydrologic unit system. This first level of classification divides the United States into 21 major geographic areas, or regions.
Subsurface water may return to the surface in groundwater flow, such as from a spring, seep, or a water well, or subsurface return to streams, rivers, and oceans.Water returns to the land surface at a lower elevation than where infiltration occurred, under the force of gravity or gravity induced pressures.
