1. What is the Equation for Net Ground Water Flow into Area across Boundary?

The Equation for Net Ground Water Flow into Area across Boundary calculates the steady-state groundwater flow through aquifers. It accounts for various hydrological parameters including water level fluctuation, specific yield, watershed area, and other recharge and discharge components.

2. How Does the Calculator Work?

The calculator uses the equation:

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

Where:

\( I \) — Net Ground Water Flowing Outside Catchment (Cubic Meter per Second)
\( h \) — Water Level Fluctuation (Meter)
\( SY \) — Specific Yield
\( A \) — Watershed Area (Square Meter)
\( RG \) — 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)
\( Is \) — Recharge of Ground Water Body (Cubic Meter per Second)

Explanation: The equation calculates the net groundwater flow by considering the water storage changes and various inflow/outflow components in a watershed area.

3. Importance of Net Ground Water Flow Calculation

Details: Accurate calculation of net groundwater flow is crucial for water resource management, understanding aquifer behavior, and assessing the water balance in hydrological systems.

4. Using the Calculator

Tips: Enter all required parameters with appropriate units. Ensure all values are positive and valid for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is Net Ground Water Flowing Outside Catchment?
A: It refers to the steady-state groundwater flow through aquifers, representing the net movement of groundwater across catchment boundaries.

Q2: How is Water Level Fluctuation measured?
A: Water Level Fluctuation is typically measured through monitoring wells and refers to the irregular rising and falling of water levels during monsoon season.

Q3: What does Specific Yield represent?
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: Why is Watershed Area important in this calculation?
A: Watershed Area defines the isolated area with a well-demarcated boundary line that drains rainwater to a single outlet, providing the spatial context for the calculation.

Q5: What are the limitations of this equation?
A: The equation assumes steady-state conditions and may not accurately represent transient hydrological events or complex geological settings.
