Question

The type of flood routing (Group I) and the equation(s) used for the purpose (Group II) are given below. Group I Group II P Hydrologic flood routing 1. Continuity equation Q Hydraulic flood routing 2. Momentum equation 3. Energy equation The correct match is

Correct answer (B) P - 1; Q - 1 & 2 only Solution Hydrologic flood routing (lumped routing) uses only the continuity equation. Hydraulic flood routing (distributed routing) uses both the continuity and momentum equations (Saint-Venant equations). The energy equation is not typically used for flood routing.
