The Possible Recharge formula estimates the potential water recharge in hard rock areas with quartzite for maximum specific yield. It calculates the gross recharge minus the natural recharge of the area, providing valuable insights into water resource management.
The calculator uses the formula:
Where:
Explanation: The formula accounts for the relationship between water level fluctuations, watershed area, and gross water draft to estimate possible recharge in hard rock quartzite areas.
Details: Accurate recharge estimation is crucial for sustainable water resource management, groundwater planning, and ensuring adequate water supply in hard rock areas with quartzite formations.
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.
Q1: What is water level fluctuation?
A: Water level fluctuation refers to the irregular rising and falling in the amount of water during monsoon season, typically measured in meters.
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, measured in square meters.
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, measured in cubic meters per second.
Q4: Why is this formula specific to hard rock areas with quartzite?
A: This formula is optimized for hard rock quartzite formations which have specific hydrological properties and maximum specific yield characteristics.
Q5: What are typical values for possible recharge?
A: Possible recharge values vary significantly based on local geological conditions, rainfall patterns, and water extraction rates, but typically range from minimal to substantial cubic meters per second.
