Questions (page 2)
Section A
Q2. Explain the functional relationship of length of slope and degree of slope in the process of soil loss by water erosion. Discuss the methods of estimation of erosivity from rainfall data. What are the factors that influence soil erodibility by wind? Discuss the impacts of different types of water erosion. (i) A watershed has an area of 1000 hectares and an average slope of 1.5%. The average 30-year, 24-hour duration rainfall is 76.2 mm, while the runoff volume calculated by the curve number technique is 31.4 mm. The length to width ratio is 3.5:1. Determine time to peak and peak discharge. (ii) Determine the size of each side of a square box inlet for a drop spillway to handle a peak flow of 3.2 cumecs over a fall of 1.5 m, if the energy head to fall ratio is not to exceed 0.6 at any time.
Section A
Q3. What are the principles and objectives of watershed management? Discuss the criteria used for prioritizing watersheds. Discuss in brief about compartmental bunding, intra-plot water harvesting, ridge furrow planting and field bunding methods used for in situ water harvesting and moisture conservation. Enlist the ex situ methods of water harvesting. Write down the principles to be adopted while calculating the spacing of bunds (contour and graded bunds). Also, calculate the height of the bunds, if the distance between the bunds is expressed by L, vertical interval between the bunds is expressed by V, width of water spread is expressed by W and land slope is expressed by S percent. Assume the maximum rainfall amount which has to stand behind the bund as 15 cm.
