GEOG 22 5 0H Water Resources Notes Unique physical properties of water The water molecule is asymmetrical with oxygen atom on one side and hydrogen atoms on the other Chemically the molecule is dipolar 0 side is H side is which induces hydrogen bonding between molecules Therefore A water has a high boiling point Weak electrostatic forces hold the liquid water molecules together making water difficult to evaporate water has a low freezing point The same weak electrostatic forces must be overcome to cause water molecules to align in the rigid crystalline structure of ice Consequently water exists as a liquid through a wide range of typical earth surface conditions water has the highest heat of vaporization of all liquids About 600 calories of heat energy are required to evaporate 1 gram of water If it were physically possible this same 600 calories could increase the temperature of the same gram of water by 600 C Evaporation serves as a vital cooling process because it absorbs about 75 ofthe excess heat energy at the earth s surface This moderates air temperatures and helps to regulate the body temperatures of animals sweating panting and plants transpiration water has a very high storage heat capacity Therefore it is useful as a coolant liquid water is denser than ice The hydrogen bonds draw liquid water molecules together These bonds are broken as ice forms and the molecules move apart It is extremely rare for the liquid state of matter to be denser than the solid state Because of this property ice oats over liquid and allows aquaticmarine life to exist in colder regions water carries an electrical charge making it an unsurpassed solvent Therefore it dissolves soil nutrients for plant uptake dilutes wastes and cleans effectively The hydrogen bonds cause water molecules to cohere to one another and to adhere to other surfaces Therefore liquid water is held by capillary action in soils and provides plants with a vital water supply 111 Global compartments of the hydrologic cycle A B C D Saltwater in ocean basins 974 Ice caps and glaciers solid 20 Groundwater mostly inaccessible 06 Readily available water 1 lakes 007 2 soil moisture 005 3 atmospheric water vapor 001 4 rivers 0001 5 biosphere 0001 Freshwater supply runoff and dependable water supply A On an average day about 10 of the water vapor passing over the US condenses and falls as precipitation Of this precipitation about 66 evaporates quickly or is transpired by vegetation The remaining 34 is runoff which enters surface water network rivers lakes and reservoirs or groundwater system recharging aquifers Only about 12 of the runoff is actually available for human use The other half is lost as oodwaters evaporation from reservoirs etc Groundwater supply water stored in aquifers A recharges slowly In drier climates aquifers are filled with geologically ancient water 10000 yr and lack meaningful recharge in present climates in some areas groundwater withdrawal rates usually for irrigated dryland agriculture are leading to dramatic drops in water table 100300 feet in parts of the High Plains of Texas in the past 50 years Many desertsemiarid regions depend on unsustainable withdrawal of groundwater to meet present needs Tucson Arizona In many coastal areas withdrawal of groundwater induces saltwater intrusion into the water supply V Types of water use A Off stream use Withdrawal water removed used most often as a coolant or solvent then returned to runoff usually in a degraded formheated polluted consumption water removed lost from runoff most often by irrigation also drinking water In stream use use of water in place for navigation hydroelectric power sh and wildlife habitat recreation Because of multiple uses for water there may be con icting interests and viewpoints on water management strategies For example hydropower generation calls for large daily uctuations in ow but reduced annual variation Canoeingrafting requires high ow in tourist season Navigational interests want a constant depth and ow Fish and aquatic wildlife do best with the large annual runoff uctuations typical from spring high water through late summerautumn low water Offstream water use in US about 2000 galdayperson 1 Industry withdraws the majority of water but returns most of it without consumptive loss but quality degraded About 1000 galdayperson 34 ofthis used for cooling of electrical power plants Agriculture withdraws irrigation evaporation about 700 galday person Because half of this is consumed agriculture accounts for ca 80 of consumptive water use in Us Globally speaking agriculture accounts for about 70 80 of all withdrawalsindustrial withdrawals are a much lower percentage of use Commercial and domestic water use is about 150 galdayperson of which about 14 is consumed the rest returned to runoff Observe that actual human drinking consumption rarely exceeds 12 galday Most water is used ushing toilets watering lawns cooking cleaning a Some examples of water used to provide products 1 a dozen eggs 40 gal 2 glass of milk 100 gal 3 1 rice 500 gal 4 1 beef 2500 gal 5 l automobile 100000 gal
