1. What is the Possible Recharge Formula?

The Possible Recharge formula estimates the potential water recharge in hard rock areas with sandstone for maximum specific yield. It calculates the gross recharge minus the natural recharge of the area, providing valuable insights for water resource management.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R = (5 \times h \times A) - DG \]

Where:

\( R \) — Possible Recharge (Cubic Meter per Second)
\( h \) — Water Level Fluctuation (Meter)
\( A \) — Watershed Area (Square Meter)
\( DG \) — Gross Water Draft (Cubic Meter per Second)

Explanation: The formula accounts for the relationship between water level fluctuation, watershed area, and gross water draft to estimate the possible recharge in hard rock sandstone areas.

3. Importance of Possible Recharge Calculation

Details: Accurate recharge estimation is crucial for sustainable water resource management, groundwater planning, and ensuring adequate water supply in hard rock areas with sandstone formations.

4. Using the Calculator

Tips: Enter water level fluctuation in meters, watershed area in square meters, and gross water draft in cubic meters per second. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is water level fluctuation?
A: Water level fluctuation refers to the irregular rising and falling in the amount of water during different seasons, particularly during monsoon periods.

Q2: How is watershed area defined?
A: Watershed area refers to an isolated area with a well-demarcated boundary line that drains rainwater to a single outlet.

Q3: What does gross water draft represent?
A: Gross water draft refers to the total volume of water extracted or utilized from a catchment area.

Q4: Why is the constant 5 used in the formula?
A: The constant 5 represents the maximum specific yield factor for sandstone formations in hard rock areas.

Q5: What are typical values for possible recharge?
A: Values vary significantly based on local geology, climate, and water usage patterns, but generally range from moderate to high values in cubic meters per second.
