Section 5: Irrigation and Drainage Engineering

Surface Irrigation: Border, Furrow & Basin Hydraulics

Subtopic: Advance and recession curves

Question Statement:

In surface furrow or border irrigation, the opportunity time for infiltration at any point along the run is equal to the difference between:

Options:

  • (A) Recession time and advance time at that point
  • (B) Total inflow time and cutoff time
  • (C) Advance time and lag time
  • (D) Ponding depth and depression storage

Answer Key:

A

Step-by-Step Solution & Explanation

Infiltration opportunity time $\tau(x) = t_{rec}(x) - t_{adv}(x)$, which is the exact duration water remains standing on the soil surface at location $x$.
