Possible Recharge refers to the gross recharge minus the natural recharge of the area in hard rock formations with karstified limestone, considering minimum specific yield characteristics.
The calculator uses the formula:
Where:
Explanation: The formula calculates potential water recharge by considering water level fluctuations, watershed area, and accounting for water extraction through gross water draft.
Details: Accurate recharge estimation is crucial for water resource management, groundwater sustainability assessment, and planning water extraction in hard rock areas with karstified limestone 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 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 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 this calculation specific to hard rock with karstified limestone?
A: Karstified limestone has unique hydrological properties with enhanced permeability and specific yield characteristics that affect recharge patterns differently than other geological formations.
Q5: What are typical values for possible recharge?
A: Values vary significantly based on geological conditions, climate, and water extraction rates. Professional hydrological assessment is recommended for specific applications.
