Permeability given Hydraulic gradient per unit head for Dams on Soft Foundations Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Permeability of Soil = (Discharge from Dam*Number of Beds)/(Head of Water*Equipotential Lines)
k = (Q_t*B)/(H_Water*N)
This formula uses 5 Variables

Variables Used

Coefficient of Permeability of Soil - (Measured in Meter per Second) - The Coefficient of Permeability of Soil describes how easily a liquid will move through the soil.
Discharge from Dam - (Measured in Cubic Meter per Second) - Discharge from Dam is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material.
Number of Beds - The Number of Beds is defined as the number of beds between each of the same potential drops.
Head of Water - (Measured in Meter) - Head of Water is defined as the height of water columns.
Equipotential Lines - Equipotential Lines is defined as the number of lines with same potential drop.

STEP 1: Convert Input(s) to Base Unit
