Watershed Management Exam With Questions AndVerified Answers 2024-2025
Watershed management - Answer The planned manipulation of one or more factors of a
natural or artificial drainage so as to effect a desired change in or maintain a desired
condition of the water resource
Flood causes - Answer excessive rains, snowmelt events, and dam failure
Affects of cutting forests - Answer Increases the amount of water available for runoff
3 Objectives of watershed management - Answer 1. Rehabilitation
2. Projection
3. Enhancement
Water flowing for a virgin forest is "pure"-est - Answer False, no different from
non-original forests
Small watershed - Answer One on which runoff patterns and quantities are not
dominated by runoff from ground water storage (base flow) or channel storage
Watershed Protection and Flood Prevention Act -or PI Provided the Soil Conservation
Services -or SCS- with authority to assist watershed management on those lands under
the influence of soil and water districts
Infiltration The rate at which water inters the soil
Surface runoff Answer Occurs when the rainfall or snowmelt is delivered to the soil
,surface faster than the rate at which the soil can absorb it
Hydrologic Cycle - Inflows Answer Global Precipitation patterns, storm characteristics,
acid rain
Hydrologic Cycle - Transit Through the System Answer Interception, infiltration
Hydrologic Cycle - Outflows Answer Runoff, evapotranspiration, groundwater
Watershed/Catchment - A topographically delineated area that is drained by a stream
system, that is, the total land area above some point on a stream or river that drains
past that point. A hydrologic unit often used as a physical-biological
socio-economic-political unit for the planning and management of natural resources
Hydrology - Answer The science that treats the waters of the earth, their occurrence
circulation and distribution, their chemical and physical properties and their action with
their environment including their relation to living things
Watershed Management - Answer The process guiding and organizing land and other
resources use on a watershed to provide desired goods and services without affecting
adversely soil and water resources
Watershed Management Practices - Answer Those changes in land use, vegetation
cover and other nonstructural and structural actions that are taken on a watershed to
achieve watershed management objectives
Forest/Range/Wildland Hydrology - Answer Refers to a branch of hydrology that deals
with the effects of vegetation and land managements, in respective settings, on water
quantity and quality, erosion and sedimentation
Limnology - Answer Study of lakes and rivers
, D- High Density-Answer 1g/cm^3 @ 4 degrees C. Best temp for cohesion. If object < 1
object will float, if > 1 object will sink. Lots of salt leads to floating
Heat Capacity-Answer Water is able to absorb high levels of heat without itself
becoming much warmer. Acts as an insulator and good for water organisms
High Latent Heat - Answer Amount of energy to cause a change from one state to
another
Cohesion -Answer Water, in liquid form, tends to have structure. Structure is greatest @
4 degree C. Water molecules are attracted to each other so high heat capacity
Adhesion - Answer Explains capillary action, this is the attribute that keeps water in the
soil, plants and animals. Helps plants get more water and brings water to the leaves
Water properties - Answer - Water is a poor conductor of electrical energy in pure form
but is a good conductor in impure form
-Water is the only substance found naturally in nature as a solid, liquid, and vapor
-Water is a university solvent
-can ingest virtually anything, including glass
-contaminated form once salt is introduced
-altitude affects boiling point
Vadose Water - Solution Water in soil surface
U.S. Water Supply - Solution 1,450 BGD (Billion Gallons a Day) collects in ground or
surface storage, the majority of this discharges to the oceans, Gulf of Mexico or over
national borders or is consumptively used or evaporates from reservoirs
Transpiration - Solution Water emitted from plants or humans
