RUSLE evaluates - correct answerannual soil loss
A=R*K*LS*C*P The R value comes from - correct answerisoerodent maps
A=R*K*LS*C*P The K value comes from - correct answerTable-Soil Erodibility Factor
A=R*K*LS*C*P The LS value comes from - correct answerTable-Topagraphic factor, high ratio of rill to interill erosion
A=R*K*LS*C*P The C value comes from - correct answerTable-Cover Management Factors
A=R*K*LS*C*P The P value comes from - correct answerTable-Practice Factor
A=R*K*LS*C*P The units for A are - correct answertons/acre/year(so you have to multiply by acre to get tons/year)
M is the - correct answerAdjustment Factor for Estimating Monthly & Portions of Annual Soil Loss
Convert M% to tons - correct answer.0% * A tons
How many cubic yards of soil will be lost - correct answerUse table-estimated Weight of Soils, then convert the units or *
A
how many pounds = 1 ton - correct answer2,000
How many cubic feet in a cubic yard? - correct answer27
Soil loss using Erosion Index % GRAPH - correct answerFuture %-Past %=% then .0% x A
A is - correct answerannual soil loss
A=RKLSCP - correct answerRUSLE
T=95(V*Qp)^0.56 KLSCP - correct answerMUSLE
T=95(V*Qp)^0.56 KLSCP T is - correct answersediment yield in tons for a storm event
T=95(V*Qp)^0.56 KLSCP V is - correct answervolume of runoff for the storm event, ac-ft
T=95(V*Qp)^0.56 KLSCP Qp is - correct answerPeak flow for the storm event, cfs
RCN comes from - correct answertables: Weighted Runoff Curve Numbers
weighted RCN= - correct answerRCN*acres + RCN*acres....../total acres
# pure nutrients needed /acre? * acre?= - correct answernutrient %/100 * # mix
# pure live seed= - correct answer#mix * germ%/100 * pure%/100
NPK - correct answernitrogen, phosphorus, potassium
Time of Concentration - correct answerThe time required for storm runoff to flow from the most remote point, in flow time,
af a drainage area to the point under consideration. It is usually associated with the design storm.
Those with an existing permit - correct answerNPDES Phase I Facility
Those with industrial activity (heavy manufacturing, construction, transportation) - correct answerNPDES Phase I Facility
