What is Snow Water Equivalent (SWE)?
Snow Water Equivalent (SWE) is the depth of water that would result if the entire snowpack were melted. It's calculated by multiplying average snow depth by snow density, providing hydrologists and water resource managers with critical information about water supply, flood potential, and seasonal runoff.
✓Water Resource Management: Accurately predicts available water for irrigation, hydroelectric generation, and municipal water supply.
✓Flood Forecasting: High SWE values indicate increased risk of spring floods and water overflow in rivers and lakes.
✓Climate Monitoring: Changes in snowpack SWE track climate trends and water availability shifts in snow-dependent regions.
