Hydraulic Gradient

The hydraulic gradient is a measure of how much water pressure or energy decreases as water moves through soil or rock. Think of it like a slope; the steeper the slope, the faster water flows. It is calculated by dividing the change in water level (or pressure) by the distance the water travels. This gradient helps us understand and predict the flow of groundwater, indicating the potential flow rate from higher to lower points. Essentially, it shows how much driving force is pushing water through underground materials.
