1. What is Maximum Potential Runoff?

Maximum Potential Runoff is generated when the movement of water into the soil is slow enough to result in water flow along the land surface and into water bodies.

2. How Does the Calculator Work?

The calculator uses the Maximum Potential Runoff formula:

Where:

• \( R_{max} \) — Maximum Potential Runoff (m³)
• \( P_T \) — Total Precipitation (m³)
• \( I_a \) — Initial Abstraction (m³)

Explanation: Initial Abstraction is a parameter that accounts for all losses prior to runoff and consists mainly of interception, infiltration, evaporation, and surface depression storage.

3. Importance of Maximum Potential Runoff Calculation

Details: Accurate runoff estimation is crucial for water resource management, flood prediction, and environmental planning.

4. Using the Calculator

Tips: Enter Total Precipitation and Initial Abstraction values in cubic meters. Both values must be valid non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Total Precipitation?
A: Total Precipitation is the sum of rainfall and the assumed water equivalent of snowfall for a given year.

Q2: What does Initial Abstraction include?
A: Initial Abstraction consists mainly of interception, infiltration, evaporation, and surface depression storage.

Q3: When is this calculation most useful?
A: This calculation is particularly useful in hydrology studies, urban planning, and flood risk assessment.

Q4: Are there limitations to this equation?
A: This is a simplified model and may not account for all complex hydrological processes in specific scenarios.

Q5: What units should be used for input values?
A: The calculator uses cubic meters (m³) for all measurements to maintain consistency.
