Dupuit equation for groundwater flow
WebEqn. (10.12) or (10.13) is called Thiem equation for unconfined aquifers or Dupuit’s equation. Like the Thiem equation for confined aquifers, this equation [Eqn. (10.12) or (10.13)] can also be used to compute Q, … WebDupit derived the following equation: Q = K (h 22 – h 12 )/2L ADVERTISEMENTS: Where, Q = flow of water per unit time, per unit width normal to the direction of flow. h 1 = head …
