New Material Coefficient C2 for Dams on Soft or Porous Foundations Calculator

Formula:

\[ C2 = \frac{C1}{V_{max}} \]

New Material Coefficient (C2):

1. What is New Material Coefficient C2 for Dams?

Definition: C2 is a constant that depends on the property of material of dam, specifically adjusted for soft or porous foundations.

Purpose: It helps engineers determine the appropriate material coefficients when designing dams on less stable foundations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ C2 = \frac{C1}{V_{max}} \]

Where:

\( C2 \) — New Material Coefficient (adjusted for foundation)
\( C1 \) — Original Material Coefficient
\( V_{max} \) — Maximum Velocity (m/s)

Explanation: The original material coefficient is divided by the maximum velocity to account for foundation conditions.

3. Importance of C2 Calculation

Details: Proper calculation ensures dam stability on soft or porous foundations by adjusting material properties for velocity effects.

4. Using the Calculator

Tips: Enter the Material Coefficient (C1) and Maximum Velocity (Vmax). All values must be > 0. Results include ±5% tolerance.

5. Frequently Asked Questions (FAQ)

Q1: Why is C2 important for soft foundations?
A: Soft foundations require adjusted coefficients to account for potential settlement and velocity effects.

Q2: How do I determine C1?
A: C1 is typically provided in engineering manuals based on dam material type.

Q3: What affects maximum velocity?
A: Water flow rate, foundation permeability, and dam design influence maximum velocity.

Q4: Why the ±5% tolerance?
A: This accounts for measurement uncertainties and material property variations.

Q5: Can this be used for all dam types?
A: Primarily for earthen and rockfill dams on soft/porous foundations.
