1. What is Water Level Fluctuation?

The Water Level Fluctuation refers to the irregular rising and falling in number or amount of water during monsoon season. It is an important parameter in hydrology and water resource management.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \frac{R + DG}{SY \times A} \]

Where:

\( h \) — Water Level Fluctuation (m)
\( R \) — Possible Recharge (m³/s)
\( DG \) — Gross Water Draft (m³/s)
\( SY \) — Specific Yield
\( A \) — Watershed Area (m²)

Explanation: The formula calculates water level fluctuation by considering the balance between water recharge and extraction relative to the watershed's storage capacity.

3. Importance of Water Level Fluctuation Calculation

Details: Accurate water level fluctuation calculation is crucial for groundwater management, drought assessment, and sustainable water resource planning.

4. Using the Calculator

Tips: Enter all values in appropriate units. Possible Recharge and Gross Water Draft in m³/s, Specific Yield as a dimensionless ratio, and Watershed Area in m². All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is Specific Yield?
A: Specific Yield refers to the volume of water that a saturated rock or soil will yield due to gravity drainage to the total volume of the rock or soil.

Q2: What is Watershed Area?
A: Watershed Area refers to the isolated area with a well demarcated boundary line, draining the rainwater to a single outlet.

Q3: What factors affect water level fluctuation?
A: Rainfall patterns, groundwater extraction, evaporation rates, and geological characteristics of the aquifer.

Q4: How often should water level measurements be taken?
A: Regular monitoring (weekly or monthly) is recommended, especially during monsoon and dry seasons.

Q5: Can this calculator be used for all types of aquifers?
A: While the formula is generally applicable, specific aquifer characteristics may require additional considerations.
