The Recharge from Rainfall in Hard Rock Laterite formula calculates the amount of water that infiltrates through hard rock laterite formations due to precipitation. This is crucial for managing groundwater resources in hard rock laterite areas.
The calculator uses the formula:
Where:
Explanation: The formula calculates groundwater recharge by multiplying the catchment area with normal monsoon rainfall and applying a constant factor of 14 specific to hard rock laterite formations.
Details: Accurate groundwater recharge estimation is essential for sustainable water resource management, aquifer replenishment assessment, and planning water supply systems in hard rock laterite regions.
Tips: Enter the catchment area in square meters and normal monsoon rainfall in meters. Both values must be positive numbers for accurate calculation.
Q1: What is the significance of the constant factor 14?
A: The factor 14 is an empirical coefficient specific to hard rock laterite formations that accounts for infiltration characteristics and recharge efficiency in these geological settings.
Q2: How is Normal Rainfall in Monsoon Season determined?
A: Normal rainfall is typically calculated as the statistical average of rainfall measured over a 30-year period during monsoon months for a specific region.
Q3: What areas are considered hard rock laterite formations?
A: Hard rock laterite refers to weathered rock formations rich in iron and aluminum oxides, typically found in tropical regions with seasonal rainfall patterns.
Q4: Are there limitations to this formula?
A: This formula provides an estimate and may need adjustment based on local geological conditions, land use patterns, and actual infiltration rates.
Q5: How accurate is this recharge estimation method?
A: While useful for preliminary assessments, more detailed hydrological studies incorporating soil properties and rainfall intensity may be needed for precise recharge quantification.
