Q2 · Level 2 · WR-HYD-0001
Horton's infiltration equation is given as f = fc + (f₀ − fc)e^(−kt). What does 'fc' represent?
Q3 · Level 4 · WR-HYD-0003
In the Muskingum method of flood routing, the storage equation is S = K[xI + (1−x)O]. What does the parameter 'x' (weighting factor) typically range between?
Q4 · Level 4 · WR-HYD-0007
In the Muskingum method, K = 12 hours and x = 0.2. The routing time step Δt = 6 hours. Calculate the Muskingum routing coefficients C₀, C₁, and C₂.
Q5 · Level 4 · WR-HYD-0004
In Gumbel's method for flood frequency analysis, the reduced variate yT for a return period T is given by:
Q6 · Level 5 · WR-HYD-0010
A river reach has Muskingum parameters K = 10 hours and x = 0.25. An inflow hydrograph shows: I₁ = 100 m³/s at t=0, I₂ = 250 m³/s at t=6h, I₃ = 400 m³/s at t=12h, I₄ = 350 m³/s at t=18h. The initial outflow O₁ = 100 m³/s. Route the flood and determine the peak outflow and its time of occurrence.
