Predict and manage runoff before it becomes a problem
Hydrology solutions
Combine drone surveys, machine telematics, and automated reporting into a single integrated platform built for surface runoff projects.
Key benefits
Track water flow paths across terrain in 3D
Automatically define catchment boundaries for your site
Identify areas of risk
Plan grading and drainage with precision to reduce risk
Plan more efficiently
Identify areas for detention, retention, or diversion
Support decision-making
Provide clear visual evidence for stakeholders and regulators
Why it matters
Surface runoff can create unexpected hazards, damage work areas, and slow construction progress. Propeller’s surface runoff tool gives teams a clear picture of how water moves across your site, highlighting ponding zones and flow paths. This allows you to design drainage, plan grading, and mitigate erosion proactively before rain or snow impacts operations.
How our surface runoff function works

Step-by-step
- Upload site survey data from drones, LiDAR, or AeroPoints
- Run surface runoff analysis—Propeller calculates water movement and ponding zones
- Visualize results in 3D or 2D, clearly showing high-risk areas
- Adjust grading or drainage designs based on actionable insights
- Share interactive maps with your team or stakeholders for coordinated planning
