SUBJECT: Elective II (Ground Water Engineering)

Attempt ALL Questions.

  1. Describe the hydrological cycle in brief. Define meteoric water and connate water. [6]
  2. What are the types of spring? Define specific storage and specific yield. [6]
  3. State and derive Darcy’s law. Describe the limitation of Darcy’s law. [6]
  4. Two observation wells 1300 m apart indicate piezometric heads of 5.6 m and 3.1 m in a homogeneous isotropic confined aquifer of thickness 21 m. η=19%, K=14 m/day, grain 1mm, ν=0.01 cm²/s.
    1. Is Darcy valid?
    2. Avg pore velocity?
    [8]
  5. Two parallel rivers 1200 m apart, depths 13 m and 8 m, K=13 m/day, rainfall 30 mm/hr, 50% infiltration. Discharge, phreatic surface, water table divide. [10]
