CIV E 445 - APPLIED HYDROLOGY

FALL 2016 - MIDTERM 2 - SOLUTION

PROBLEM 3: ESSAY QUESTIONS

  • 1 sq mi.

  • 400 sq mi.

  • Penman combined Dalton's mass transfer evaporation model with an energy balance method to create a combination model of evaporation for practical use.

  • Length L, Manning roughness n, slope S, and effective rainfall intensity i.

  • The Creager curve represents the runoff diffusion present in catchments; the greater the catchment area, the smaller the peak discharge per unit of area.

  • A lysimeter is an instrument designed to measure actual evapotranspiration. It is used in the field, for applications in irrigation and agricultural hydrology.

  • The four input variables in the determination of a runoff curve number method are:

    1. Hydrologic soil group: A, B, C, D.

    2. Land use and treatment class: agricultural, urban, range, forest.

    3. Ground surface condition: poor, fair, good

    4. Antecedent Moisture Condition: I, II, III.

  • The peak rate factor in the NRCS synthetic unit hydrograph methodology is: PRF = 484.
