Snow Water Equivalent Calculator

Understanding Snow Water Equivalent (SWE)

Snow Water Equivalent (SWE) is a crucial measurement in hydrology and weather science that tells us how much water would result if you melted a snow sample completely. This value is essential for:

• Flood forecasting and prevention
• Water resource management
• Avalanche risk assessment
• Climate studies and research

How to Use This Calculator

1. Enter the measured snow depth in inches
2. Input the snow density as a percentage (typically 5-15% for fresh snow, up to 40% for compact snow)
3. Click "Calculate" to get your result

Formula Used

SWE = Snow Depth × (Snow Density / 100)
