  • a
    Write water budget equation
  • b
    Define actual evapotranspiration
  • c
    Write 2 basic assumptions of unit hydrograph
  • e
    Write down the Ryves formula of flood estimation
  • g
    Draw diagram to show mutual interference of wells
  • h
    What is perched water table. (i) What are different types of contamination in groundwater? (j) Define tube well
Section BAttempt any three o f t h e f o l l o w i n g : 10 x 3 = 30
  • a
    What are different forms of precipitation? Also draw a sche matic section of tropical cyclone
  • b
    Explain double mass curve of rainfall. Also write the steps to correct the consistency of data
  • c
    Explain risk, reliability a nd safety factors. Flood frequen cy computations for a river by using Gumble’s method, yielded the following results. Calculate the flood magnitude in the river with the return period of 1000 years. Return Period T (Years) Peak Flood (m 3/sec)
  • d
    Derive an equation to calculate discharge from anunconfined aquifer for steady state conditions
  • e
    Write the applicability of water wells. Mention its advanta ges and disadvantages
Section CAttempt any one p a r t o f t h e f o l l o w i n g : 10 x 1 = 10
  • a
    Explain in detail different types of recording rain gauges. The average annual rainfall of 5 rain gauges in a basin 890, 54 0,450,410 and 550 mm respectively. Calculate the additional gauges required, if i t is desired to limit the error to only 15%?
  • a
    Explain time characteristics of hydrograph
  • b
    Define Hydrograph and its components in detail with neat sketch . Explain Unit Hydrograph by defining 1-hour, 6-hour and 24- hour unit hydrograph
  • a
    A bridge has an expected life of 25 year and is designed fo r a flood magnitude of return period 100 years. Calculate the following
  • a
    What is the risk of this hydrologic design?
  • b
    If a 10% risk is acceptable, what return period will have to be adopted?
  • b
    Analysis of annual flood series of a river yielded a sample mean of 1000 m3/s and standard deviation of 500 m3/s. Derive the design flood of a structure on this river to provide 90% assurance that the structure will not fail in ne xt 50 years. Use Gumbles method and assume the sample size to be very large
  • a
    Drawdown in observation well is 5m and 10 m and correspondi ng radius from well is center is 20m and 15 m respectively. Radius of circle o f influence for a well is 500 meters. A tube well is 0.65 m in diameter. The unconfined aquifer is of 25 m depth. After drawdown depth of water is 12 m in the well. Permeability of soil is 27.50 m/day. Calculate the discharge from the well
  • b
    Explain different types of saturated formations
  • a
    Differentiate between Open wells and tube wells. Provide it s method of construction by analyzing the soil and ground level characteristics
  • b
    Write the well construction methods in detail. Also Describ e the operation and maintenance of water wells
