    About the Water Balance Calculator

    The Water Balance Calculator helps estimate the net change in soil or watershed water storage by accounting for precipitation, evapotranspiration, surface runoff, and percolation losses. It is essential for understanding irrigation needs, drought analysis, and hydrological planning.

    • Features

    • Calculates water surplus or deficit from hydrological inputs.
    • Displays detailed component breakdown and recommendations.
    • Useful for irrigation, water resource, and agricultural management.

    • How to Use

    1. Enter precipitation, evapotranspiration, runoff, and percolation values.
    2. Provide an initial storage estimate (e.g., soil moisture before rainfall).
    3. Click “Calculate” to determine water balance and final storage.
    4. Review recommendations for improving water management.
