1. What is the Equation For Recharge From Stream Into Ground Water Body?

The Equation For Recharge From Stream Into Ground Water Body calculates the recharge of groundwater from a stream, which refers to the hydrologic process where water moves downward from surface water to groundwater. This equation accounts for various hydrological parameters to estimate groundwater recharge accurately.

2. How Does the Calculator Work?

The calculator uses the equation:

\[ Is = (h \times A \times SY) - RG + DG + B - I \]

Where:

\( Is \) — Recharge of Ground Water Body (Cubic Meter per Second)
\( h \) — Water Level Fluctuation (Meter)
\( A \) — Watershed Area (Square Meter)
\( SY \) — Specific Yield
\( RG \) — Gross Recharge due to Rainfall (Cubic Meter per Second)
\( DG \) — Gross Water Draft (Cubic Meter per Second)
\( B \) — Base Flow into the Stream from the Area (Cubic Meter per Second)
\( I \) — Net Ground Water Flowing Outside Catchment (Cubic Meter per Second)

Explanation: The equation calculates groundwater recharge by considering water level fluctuations, watershed characteristics, and various inflow/outflow components of the hydrological system.

3. Importance of Recharge Calculation

Details: Accurate groundwater recharge estimation is crucial for water resource management, sustainable groundwater extraction, and understanding the hydrological balance of watershed areas.

4. Using the Calculator

Tips: Enter all required parameters with appropriate units. Ensure water level fluctuation, watershed area, and specific yield are positive values. All inputs must be valid numerical values.

5. Frequently Asked Questions (FAQ)

Q1: What is water level fluctuation?
A: Water level fluctuation refers to the irregular rising and falling in the number or amount of water during monsoon season.

Q2: What does watershed area represent?
A: Watershed area refers to the isolated area with a well-demarcated boundary line, draining the rainwater to a single outlet.

Q3: 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.

Q4: What is base flow?
A: Base flow into the stream from the area refers to the flow that is not runoff; it is water from the ground, flowing into the channel over a long time and with a certain delay.

Q5: What are typical values for these parameters?
A: Parameter values vary significantly based on geographical location, soil type, climate conditions, and hydrological characteristics of the specific watershed being studied.
