How to Use This Calculator
- Enter Start Depth, End Depth, and Horizontal Distance.
- Review Average Depth (m) and Slope Angle (°).
- Use Depth Difference (m) and Gradient (%) to inform your decision.
- Use the chart to visualize the results and explore different scenarios by adjusting inputs.
How the result changes with End Depth
| End Depth | Average Depth | Slope Angle |
|---|---|---|
| 1,100 | 650 m | 0.52° |
| 3,850 | 2,025 m | 2.09° |
| 7,150 | 3,675 m | 3.98° |
| 9,900 | 5,050 m | 5.54° |
What each input means
- Start Depth
- Water depth at the starting point of the profile in meters below sea level.
- End Depth
- Water depth at the ending point of the profile in meters below sea level.
- Horizontal Distance
- Horizontal distance between start and end points in kilometers.
