In hydrology , the inflow of a body of water is the source of the water in the body of water. It can also refer to the average volume of incoming water in unit time . It is contrasted with outflow hydrology outflow . All bodies of water have multiple inflows, but often, one inflow may predominate and be the largest source of water. However, in many cases, no single inflow will predominate and there will be multiple primary inflows. For a lake , the inflow may be a river or stream that literally flows into the lake. Inflow may also be, strictly speaking, not flows, but rather precipitation meteorology precipitation , like rain . Category Hydrology geo term stub hi ... more details

Unreferenced date December 2009 In water related science and engineering there are two similar but distinct definitions in use for drawdown . In subsurface hydrogeology , drawdown is the change in hydraulic head observed at a water well well in an aquifer , typically due to pumping a well as part of an aquifer test or well test . In surface water hydrology and civil engineering , drawdown refers to the lowering of the water level in a man made reservoir water reservoir or tank. In either case, drawdown is the change in head or water level relative to background condition, indicating the difference in head which has occurred at a given location relative an initial time at the same location. A record of hydraulic head through time is more generally called a hydrograph in both groundwater and surface water . Effects Aquifer drawdown or overdrafting and the pumping of fossil water increases the total amount of water in the hydrosphere that is subject to transpiration and evaporation thereby causing accretion in water vapour and cloud cover which are the primary absorbers of infrared radiation in the earth s atmosphere . Adding water to the system has a global warming forcing effect on the gaia whole earth system , an accurate estimate of which hydrogeological fact is yet to be quantified.

Unreferenced date December 2009 Chemical hydrology or hydrochemistry is the subdivision of hydrogeology that deals with the chemistry chemical characteristics of water . Water H sub 2 sub O is a unique solvent for inorganic components which can be negatively charged anions, positively charged cations or uncharged species. One reason water is a universal solvent is that water dissociates into H sup sup and OH sup sup . The pH of water is one of the key parameters, defined as the negative decadic logarithm of H sup sup activity. Further key parameters include temperature, redox potential, and electrical conductivity . However, to characterize the water quality one has to determine the major, minor, and trace elements and the formation of complexes between the constituents and organic compounds. Knowledge of water chemistry is essential for making use of water as drinking water , irrigation water, or industrial purposes.

Armor , in hydrology and geography is the association of surface pebble s, rocks or boulder s with stream bed s or beach es. Most commonly hydrology hydrological armor occurs naturally however, a man made form is usually called riprap , when shoreline s or stream banks are fortified for erosion protection with large boulders or sizable manufactured concrete objects. When armor is associated with beach es in the form of pebbles to medium sized stones grading from two to 200 millimeters across, the resulting landform is often termed a shingle beach . Hydrological modeling indicates that stream armor typically persists in a flood stage environment. ref name Wilcock Cite journal last Wilcock first Peter R. coauthors DeTemple, Brendan T. date April 2005 title Persistence of armor layers in gravel bed streams journal Geophysical Research Letters volume 32 issue 8 bibcode 2005GeoRL..3208402W doi 10.1029 2004GL021772 pages L08402 ref Page needed date October 2008 See also Storm tide Bridge scour References Reflist DEFAULTSORT Armor Hydrology Category Geology Geology stub nl Armour waterbouwkunde ... more details

Isotope hydrology is a field of hydrology that uses isotope isotopic dating to estimate the age and origins of water and of movement within the hydrologic cycle . The techniques are used for water use policy , map ping aquifer s, conserving water supplies, and controlling pollution . It replaces or supplements past methods of measuring rain , river levels and other water body bodies of water over many decades. Details Water molecule Water molecules carry unique fingerprints, based in part on differing proportions of the oxygen and hydrogen isotopes that constitute all water. Isotopes are forms of the same element that have variable numbers of neutron s in their nuclei. Air , soil and water contain mostly oxygen 16 sup 16 sup O . Oxygen 18 sup 18 sup O occurs in approximately one oxygen atom in every five hundred and is a bit heavier than oxygen 16, as it has two extra neutrons. From a simple energy standpoint this results in a preference for evaporation evaporating the lighter sup 16 sup O containing water and leaving more of the sup 18 sup O water behind in the liquid state called fractionation . Thus seawater tends to be richer in sup 18 sup O and rain and snow relatively depleted in sup 18 sup O. Radiocarbon dating Carbon 14 dating is also used as part of isotope hydrology as all natural water contains dissolved carbon dioxide .

For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow , whereas an engineer operating a reservoir system might define discharge as outflow , which is contrasted with inflow hydrology inflow . The units of measurement units that are typically used to express discharge include m s cubic meters per second , ft s cubic feet per second or cfs and or acre feet per day. ref Dunne, T., and Leopold, L.B., 1978, Water in Environmental Planning San Francisco, Calif., W.H.

Geographic Information Systems GIS has become a particularly useful and important tool in hydrology and to hydrologists in the scientific study and management of water resources . Climate change and greater demands on water resources require a more knowledgeable disposition of arguably one of our most vital resources. As every hydrologist knows, water is constantly in motion. Because water in its occurrence varies spatially and temporally throughout the hydrologic cycle , its study using GIS is especially practical. GIS systems previously were mostly static in their geospatial representation of hydrologic features. Today, GIS platforms have become increasingly dynamic, narrowing the gap between historical data and current hydrologic reality. The elementary water cycle has inputs equal to outputs plus or minus change in storage. Hydrologists make use of a hydrologic budget when they study a Drainage basin watershed . A watershed is a spatial area, and the occurrence of water throughout its space varies by time. In the hydrologic budget are inputs such as Precipitation meteorology precipitation , surface flows in, and groundwater flows in. Outputs are evapotranspiration , infiltration hydrology infiltration , surface runoff , and surface groundwater flows out. All of these quantities, including storage, can be measured or estimated, and their characteristics can be graphically displayed in GIS and studied. As a subset of hydrology, hydrogeology is concerned with the occurrence, distribution, and movement of groundwater . Moreover, hydrogeology is concerned with the manner in which groundwater is stored and its availability for use. The characteristics of groundwater can readily be input into GIS for further study and management of water resources.

nowiki nowiki In hydrology , behavioral modeling is a Scientific modelling modeling approach that focuses on the modeling of the behavior of hydrological system s. The behavioral modeling approach makes the main assumption that every system, given its environment, has a most probability probable behavior. This most probable behavior can be either determined directly based on observable system characteristics and expert knowledge or, the most frequent case, has to be inferred from the available information and a likelihood function that encodes the probability of some assumed behaviors. This modeling approach has been proposed recently by Sivapalan et al. 2006 in Drainage basin watershed hydrology.
