BE 322 TEST 2 STUDY GUIDE Module 2 ( Infiltration-closed book)  What is infiltration? What happens if rainfall rate exceeds infiltration rate? List four factors that influence the rate of infiltration Sketch Typical patterns for average and instantaneous intake rates and cumulative depth of infiltration Module 2 ( Infiltration – open book) Solve infiltration problem using Kostiakov’s equation. Know how to develop Kostiakov parameters from experimental data. [15 points] The following graph was developed from infiltrometer test data for the soils at the Walker golf course (Clemson University): Log i Vs. Log t 1 0.8 0.6 . c i 0.4 ( i 0.2 o l 0 0 0.5 1 1.5 2 2.5 -0.2 -0.4 -0.6 -0.8 log t ( t in min.) The straight line equation from graph was obtained as: y = 0.6536x - 0.6176 a) Compute  and c values of the Kostiakov equation from the above graph and calculate the time needed in minutes to achieve a cumulative infiltration depth of 6.5 cm [10 pts]. b) [5 pts].Compute the time in hrs. needed to attain an infiltration rate of 1.416 cm/hr  Horton Equation -kt  f(t) = fc + (0 - fc)e Solve infiltration problem using Horton’s equation. Know how to develop Horton parameters from experimental data. Use of phi to determine watershed infiltration rate Use the rainfall data listed to determine the φ index for a watershed having a total runoff of 4.9 inches for this storm. All we need after that is to find the line level that allows the “runoff” part of the hyetograph to be equal to exactly 4.9 inches Module 3 ( Erosion closed book) 1. DEFINE: Weathering— Erosion— Deposition— 2. What is the difference between mechanical and chemical weathering? 3. EXPLAIN how climate affects the rate of weathering: Temperature— Amount of precipitation (rain, etc.)— 4. What is the #1 agent of erosion? 5. What was the Dust Bowl? 1931-1939 there was a drought called the “dust bowl”. 6. What caused the Dust Bowl? 7. How do we avoid future dust bowl? 8. How can plants help prevent soil erosion? 9. EXPLAIN how these plowing methods prevent erosion: Contour plowing— Conservation plowing— 10. What is soil conservation? Why is it important? 11. DEFINE and give EXAMPLES of: Natural resources— Renewable resource— Nonrenewable resource— Inexhaustible resource— 12. How can a renewable resource run out? Give an example. 13. A community is considering cutting down a small forest to build a new neighborhood. DESCRIBE: 2 costs of cutting down the forest— 2 benefits of cutting down the forest— 14. What is soil erosion: 15. What are the four types of erosion by water? 16. What is rill erosion? 17. What is gully erosion? 18. What is sheet erosion? 19. Channel erosion 20. Write the Universal Soil Loss equation and name the five factors 21. List 4 factors that influence soil erosion? 22. What is Stokes Law? 23. What is MUSLE? Module 3 ( Erosion open book) Application of USLE-T=ARKLSCP, T= ARKLSVM, MUSLE to quantify soil loss (See HW problems) If the predicted soil erosion for a given set of conditions is 15 tons/acre for a 600-ft slope length. Three terraces are installed on this field at a 200-ft slope length, all other conditions remain unchanged and the slope is 10%. What is the new predicted soil erosion rate for this field? Module 4 ( Erosion open book) Use a single-triangle unit hydrograph procedure to develop a storm hydrograph for a storm event (see class notes and HW)
