Question Paper
Explain hydrologic cycle with the help of neat sketch depicting its components.
Differentiate between measurement and estimation of runoff. What are the different methods of runoff estimation
What do you understand by time of concentration A micro watershed comprises of 60 ha area. The watershed is divided into two parts, based on its land use and soil texture, in which 1st part of 40 ha with 12% slope is under wood land and second part of 20 ha with slope under cultivation land. The maximum length of flow is 2000 m to the outlet. The average slope of channel is 6%. Calculate the time of concentration.
What are the important factors affecting surface runoff
Write a water balance equation of a catchment and also describe its inflow and outflow components.
Define infiltration. How do type of soil surface and initial soil moisture influence infiltration rate?
Define evaporation. List factors influencing evaporation.
Differentiate between field water use efficiency and crop water use efficiency.
Differentiate between open channel and pipe flow. List different channel parameters influencing the channel discharge.
Write Manning's equation for estimation of velocity in an open channel, define its different terms also.
Compute discharge in an open channel of rectangular cross section having 40 cm width and 20 cm depth of flow. Assume hydraulic slope and roughness coefficient are 0.005 and 0.018, respectively.
Differentiate between percolation and seepage. Explain the factors affecting percolation.
What do you understand by point rainfall, how can it be measured and name commonly used non-recording rain gauge?
Describe the arithmetic mean method used for estimation of average rainfall over an area.
