  2. The normal annual rainfall of stations A, B, C and D in a catchment are 809.7, 675.9, 762.8, 920.1 mm respectively. In the year 2023, the station D was inoperative while stations A, B, C recorded annual rainfall of 911.1, 722.3, 798.9 mm respectively. Use normal ratio method to estimate the missing rainfall data at D in the year 2023.

Q.3 Solve both questions:[14]

  1. Discuss various factors affecting evaporation. What are the possible sources of error in the measurement of the rainfall.

  2. The following meteorological data pertain to a large reservoir with water spread area 15 km2. The data represents the average values for the day. Water temperature = 24\circ C, Air Temperature = 26\circ C, Atmospheric pressure 752 mm of mercury, wind speed at 0.5 m above G.L = 25.3 km/h, relative humidity r = 46%. Estimate average daily evaporation from the reservoir and evaporation loss from the reservoir for a period of one week using Meyer's and Rohwer's equations.

Q.4 Solve both questions:[14]

  1. What is runoff? Explain with sketch different types of catchments.

  2. Explain the rainfall-runoff relationship using regression analysis (any one method).

Q.5 Solve both questions:[14]

  1. Define "unit hydrograph". What are the assumptions, uses and limitations of hydrograph theory?

  2. A 6h storm produced rainfall intensity of 7, 18, 25, 12, 10 and 3 mm/h in successive one hour interval over a basin of 800 sq.km. The resulting runoff is observed to be 2640 hectare-metres. Determine the φ-index for the basin.

Q.6 Solve both questions:[14]

  1. Explain with equations of various types of irrigation efficiencies.

  2. The gross commanded area for an irrigation canal is 20,000 hectares out of which 75% is culturable CA. Intensity of irrigation is 40% for rabi and 10% for rice. If Kor period is 4 weeks for rabi and 2.5 weeks for rice, determine outlet discharge. Outlet factors for rabi and rice may be taken as 1800 ha/cumec and 775 ha/cumec respectively. Also calculate delta for each case.
