Width of Elementary Gravity Dam Solution

STEP 0: Pre-Calculation Summary

Formula Used

Base Width = Height of Elementary Dam/sqrt(Specific Gravity of Dam Material-Seepage Coefficient at Base of Dam)
B = H_d/sqrt(S_c-C)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Base Width - (Measured in Meter) - Base width is the maximum thickness or width of a dam measured horizontally between upstream and downstream faces and normal to the axis.
Height of Elementary Dam - (Measured in Meter) - Height of elementary dam is the vertical distance from the natural streambed at the downstream toe of the dam to the crest.
Specific Gravity of Dam Material - Specific gravity of dam material the material of the dam has a specific gravity and the dam is designed as an elementary profile ignoring uplift.
Seepage Coefficient at Base of Dam - Seepage coefficient at base of dam is the impounded water seeks paths of least resistance through the dam and its foundation.

STEP 1: Convert Input(s) to Base Unit

Height of Elementary Dam: 30 Meter --> 30 Meter No Conversion Required
Specific Gravity of Dam Material: 2.2 --> No Conversion Required
Seepage Coefficient at Base of Dam: 0.8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

B = H_d/sqrt(S_c-C) --> 30/sqrt(2.2-0.8)

Evaluating ... ...

B = 25.3546276418555

STEP 3: Convert Result to Output's Unit

25.3546276418555 Meter --> No Conversion Required

FINAL ANSWER

25.3546276418555 ≈ 25.35463 Meter <-- Base Width

Width of Elementary Gravity Dam Formula

LaTeX Go

Base Width = Height of Elementary Dam/sqrt(Specific Gravity of Dam Material-Seepage Coefficient at Base of Dam)
B = H_d/sqrt(S_c-C)

Why Gravity Dam is thick from bottom?

The pressure in the liquid increases with depth. Thus, as depth increases, more and more pressure is exerted by water on the wall of a dam. A thicker wall is required to withstand a greater pressure, therefore, the wall of the dam is made with the thickness increasing towards base.

How do you find the Width of a Dam?

Measure the surface dimensions of the water. Pace the length and breadth of the bank at the water surface for rectangular or square dams. Round dams can be measured by pacing the circumference of the bank at water level, then divide this distance by 3.142 (π) to calculate the diameter
