Watershed Analysis

Trust Terrayn’s Watershed Analysis for Safe & Sustainable Development

Water management is critical to any infrastructure project. At Terrayn, our Watershed Analysis services provide the data and insights you need to manage hydrology risks and meet environmental regulations.

Our approach captures air, land, and water data for a complete hydrological picture.

Our Watershed Services

Drainage Area Mapping

IDF Curve & Rainfall Analysis

Culvert & Crossing Sizing

Provincial & Federal Compliance (COP & DFO)

We identify how water interacts with your site—ensuring safe, compliant designs.

Bathymetric Surveys

Precision Mapping Below the Surface

Understanding what lies beneath the water is just as important as mapping the land. At Terrayn, we utilize advanced bathymetric surveys to deliver accurate, underwater terrain data essential for effective project planning and environmental management.

Using unmanned sonar-equipped vessels, our bathymetric surveys deploy high-frequency echo sounders that emit sound waves to the bottom of rivers, lakes, or reservoirs. These sound waves bounce back, allowing us to precisely measure:

This data is then processed into detailed 3D models and contour maps of the underwater environment.

Terrayn’s Air, Land and Water Approach
Using LIDAR
For Advanced Watershed Analysis

LIDAR technology transforms how we approach watershed analysis. By creating detailed 3D models of terrain and drainage areas, we can:

  • Accurately map watershed boundaries and flow paths.
  • Identify potential flood zones and drainage issues before they arise.
  • Support infrastructure design with precise topographical data.

 

With Terrayn’s LIDAR-enhanced analysis, you gain the insights needed to design resilient water management systems that protect both your project and the environment.

Assessing Hydrology and Ecological Impacts

Understanding how water interacts with your site is only part of the equation—assessing ecological impacts is equally critical. Terrayn evaluates:

  • Hydrological Flow Patterns: How rainfall and runoff will behave across your site.
  • Environmental Sensitivities: Identifying wetlands, habitats, and protected areas.
  • Compliance Risks: Ensuring adherence to environmental regulations and best practices.

Our holistic approach balances development needs with environmental stewardship, helping you avoid regulatory pitfalls and costly remediation efforts.

Your Build, Our Expertise.

Terrayn doesn’t just collect data—we deliver comprehensive, easy-to-understand reports that guide decision-making. Our watershed reports include:

  • Detailed drainage maps and flow calculations.
  • Culvert and crossing sizing recommendations.
  • Compliance checklists aligned with provincial and federal codes.
  • Visual diagrams to support regulatory submissions and stakeholder communication.

With our reporting, you’ll have the documentation and insights needed to implement effective, compliant water management strategies—keeping your project moving forward with confidence.
