What are some ways to stabilize runoff outlets? ------CORRECT ANSWER- --------------Rip rap, paved flume, level spreader, linings, concrete slope paving What are some examples of scour protection? ------CORRECT ANSWER--- ------------Plunge pools, rip rap, paved outlets, levelers What are some examples of non-vegetative cover? ------CORRECT ANSWER---------------Mulching, riprap, soil stabilizers What are some biotechnical ways to strengthen subsurface? ------ CORRECT ANSWER---------------Wattling, fiber roll, live cribwall, branch packing, willow staking Formula for % of pure live seed? ------CORRECT ANSWER---------------% of germination x % purity Formula for fertilizer amendments? ------CORRECT ANSWER--------------- Kg of pure live seed = %nutrient/100 x (kg. mix) What is the best stabilization technique you can have? ------CORRECT ANSWER---------------Preserving existing vegetation
The process in which, by the actions of wind or water, soil particles are detached and transported. ------CORRECT ANSWER---------------Erosion Eroded material suspended in wind or water. ------CORRECT ANSWER----- ----------Sediment The deposition of eroded material. ------CORRECT ANSWER--------------- Sedimentation What bears the impact of quantity and quality degradation from erosion? --- ---CORRECT ANSWER---------------Receiving Waters Raindrop impact energy is enough to dislodge surface sediment. ------ CORRECT ANSWER---------------Splash Erosion Rain splash detaching soil particles lifting them up and removing them by shallow "sheets" of water flowing down the sloped soil surface. ------ CORRECT ANSWER---------------Sheet Erosion As flow concentrates, small channels begin to form in the soil surface. ------ CORRECT ANSWER---------------Rill Erosion Runoff cuts rills deeper and wider or several rills join to form a large channel. ------CORRECT ANSWER---------------Gully Erosion
