The Recharge from Rainfall in Alluvial West Coast refers to the process by which rainwater infiltrates the soil and percolates through the alluvial deposits to replenish the groundwater aquifers. This calculation is essential for managing groundwater resources in coastal regions.
The calculator uses the formula:
Where:
Explanation: The formula calculates the groundwater recharge by multiplying the catchment area by the normal monsoon rainfall and a conversion factor of 10.
Details: Accurate recharge calculation is crucial for sustainable groundwater management, preventing over-extraction, and maintaining the balance of coastal aquifer systems.
Tips: Enter the area of computation in square meters and normal rainfall in meters during monsoon season. All values must be positive numbers.
Q1: Why is a conversion factor of 10 used in the formula?
A: The factor 10 converts the units from m³ to m³/s when considering appropriate time scales for recharge calculations.
Q2: What is considered normal rainfall in monsoon season?
A: Normal rainfall refers to the statistical average of rainfall measured over a specified period, typically 30 years, during the monsoon months in the region.
Q3: How does this calculation help in water resource management?
A: It helps quantify the amount of water replenishing aquifers, which is essential for sustainable groundwater extraction planning.
Q4: Are there limitations to this calculation method?
A: This method provides an estimate and may not account for variations in soil permeability, evaporation rates, or other local hydrological factors.
Q5: Can this formula be used for non-coastal areas?
A: While developed for west coast alluvial areas, the formula may be adapted for other regions with similar geological characteristics.
