The simple hydraulics and waterworks calculator to calculates dams on soft or porous foundations discharge value using Darcy’s Law.
Darcy’s law furnishes a theoretical basis for providing adequate length of water travel beneath a dam. This relation may be expressed as Q = C1 * (H * A) / L.
Formula:
Q = C1 × (H × A) / L
where,- H - head
- L - length
- C1 - a coefficient that depends on the character of the material
- A - cross sectional area
- Q - discharge
