IV. Hyd rologic P rocesses on Watersheds A. The hydrologic cycle.
This cycle may be divided into four major functional parts and expressed as an equation or model. Equation:
P = RO + ET S RO = P ET S
P is precipitation RO is runoff E T
Sept. 10th: -An ideal watershed is circular Mapping watersheds Characteristics of contour lines: 1. Single continuous lines always closes 2. Spacing indicates steepness 3. V indicates a draw or stream course, points up stream 4. U indicates a spur or ridg
Sept. 17th: Active surface contentwhere energy exchange takes place Active surface characteristics (fixed) -slope -aspect (which way slope is facing) -elevation (higher to cooler/wetter) -location with respect to other features (topographic & geologic) -s
Sept. 22nd: Precipitation process -Ice crystal theoryair rises & expands; as air cools humidity goes up water molecules in gas form converts to a fluid; ice crystal is so attractive to water vapor that more and more water molecules stick to it; then ice c

Vocabulary: Hydrology- the science dealing with the occurrence of water on the earth; its physical and chemical properties, transformations, combinations and movements especially with the course of water movement from the time
II. Water Resource Problems
Water becomes a problem for humans only when it is inadequate to meet the demands placed on it by us or when it interferes with our safety or convenience. PowerPoint-Water Resource Problems-The problems encountered can be most
III. Watershed Management Planning & Application OR Watershed Analysis
A.
Objectives- Lets examine what we hope to accomplish in terms of making a watershed management plan and implementing it (Planning objectives not objectives of a plan!)

VI. Watershed Protection
We have now examined not only the basic processes which a watershed functions but also a method for formulating a management plan which can be imposed on a watershed. Throughout our discussions we have referenced certain act-resul

A. Int roduction The whole area of watershed restoration is r ather complex and success ratios are in general rather low. This is not to say we should not t ry restorative measures where needed but
Sept. 8th: Planning Procedures: -Info from U.S.G.S. (dept. of interior) -or oil companies -army corps of engineers -Soils: county records; internet; forest service; N.R.C.S. (best place) Natural Resource Conservation Service; you can also get experts in t
Sept. 1st: Watershed management- directing a watershed; uses water, land, and processes of management Water is a raw material and finished product, and the factory for it is the watershed Objectives of Watershed Management: 1. Maintain and/or increase wat
Sept. 3rd: Too much: -Regime: high flow, too much water -traditional solutions: increase capacity of the channel (ie. dykes, NOLA) -or decrease the volume of water; catch water (dam) for flood control *probably not possible for us to build anything that w
