Multiple issues expert subject August 2009 refimprove August 2009 context August 2009 Catchment hydrology , is the study of the hydrology regarding drainage basin catchments . Water balance Catchment hydrology is based on the principal of continuity, which is used to perform a water balance on a catchment math I O dS dt math , where math I math inputs P, precipitation meteorology precipitation OW, occult water , math O math outputs ET, evapotranspiration R, Surface runoff runoff , and math dS dt math the change in catchment storage over time. Neglecting the minor inputs of occult water, the water balance can be revised to math P R ET dS dt math . Finally, considering a catchment on a long time scale, typically a year or more, removes the storage component from the equation math P R ET math . ref Kendall and McDonnell, 1998.

unreferenced date March 2012 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 . Outflow is the amount of water that leaves the country. Inflow is mostly used when referring to rivers, and the amount of water in units that enters the country. 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 . Inflow can also be used to refer to groundwater recharge .

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 may be a contributing factor to sea level rise. ref cite web url http www.uu.nl EN Current Pages Wereldwijdonttrekkenvangrondwaterleidttotzeespiegelstijging.aspx title Rising sea levels attributed to global groundwater extraction publisher University of Utrecht accessdate February 8, 2011 ref References reflist DEFAULTSORT Drawdown Hydrology Category Hydrology Category Aquifers Category Water Category Water wells Category Hydraulic engineering ht Rabatman ... more details
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 Category Geomorphology Category Sediments geomorph 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 . GH Dury and Bradshaw model MJ Bradshaw are two hydrologists who devised models showing the relationship between discharge and other variables in a river.

Description Seeps are usually not of sufficient volume to be flowing beyond their above ground location. They are part of the limnology geomorphology system. Like a higher volume spring hydrosphere spring , the water is only from underground sources. Seeps often form a puddle , and are important for small wildlife , bird , and butterfly habitat and moisture needs. When they support mud puddling many butterfly Lepidoptera species can obtain nutrient s such as salt s and amino acid s, including some types that are endemism endemic endangered species .

Geographic information system s GISs have become a 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.

All parts of the country have some outflow. All surface water gravitates towards its southern centre, and from there, is united in the Danube , which flows into the Black Sea . The whole of Hungary lies within the Danube drainage basin . The total length of all the irrigation systems and inland waterways in the country is about convert 26000 km abbr on . The annual water balance of the country shows a surplus. Yearly about convert 100 km3 cuft abbr on of water leaves the country towards the Black Sea. From that, precipitation meteorology precipitation amounts for only 10 , the rest being provided by the incoming rivers of surrounding countries. Rivers Hydrographically Hungary can be divided into two roughly equal parts the drainage basin s of the Danube and the Tisza . The present network of Hungary s rivers began to take shape at the end of the Tertiary and the beginning of the Quaternary periods when the Pannonian Sea retreated from the basin. The rivers in Hungary reach their lowest level at the end of the summer, the beginning of the autumn, or sometimes in the winter. Both the Danube and the Tisza have two regular floods each year, the early spring icy flood and the early summer green flood . The icy flood is the result of the thaw weather thaw in the mountains surrounding the Carpathian Basin, when the rivers in the plain are usually still frozen. Before the river flows were controlled, the piled up ice sheets of the river could form tremendous barriers, which in turn could cause devastating floods. This phenomenon can still be a real danger after cold winters, and a small fleet of icebreaker s is used on the two rivers to fight agai ... more details
