Hydrographic Surveying Services

Our hydrographic surveying services deliver high-resolution bathymetric data that engineers, municipalities, and industrial owners rely on for critical decision making. Using autonomous survey platforms equipped with advanced sonar and RTK GPS, we map underwater terrain with precision in ponds, reservoirs, rivers, and confined water bodies where traditional methods fall short.

The data we collect supports infrastructure assessments, sediment volume calculations, flood modeling, environmental compliance, and dredging design. By providing accurate and defensible measurements we help clients reduce risk, improve project efficiency, and plan with confidence.

Why Hydrographic Data Matters

Accurate underwater data reduces uncertainty in design, improves cost control for dredging and maintenance, strengthens regulatory compliance, and protects critical infrastructure. Poor data leads to overestimated budgets, under designed systems, and avoidable risk. Schoel delivers defensible, high-resolution bathymetric information that supports confident engineering decisions.

• RTK-enabled positioning

• Side scan, down scan or single-beam sonar capability

• Georeferenced deliverables compatible with Civil 3D and GIS

• Volume calculations and CAD-ready surfaces

As your partner in Hydrographic Surveying, we offer:

Schoel provides high-resolution bathymetric mapping to define underwater terrain with precision and clarity. Our surveys establish accurate depth profiles, identify sediment accumulation, and calculate material volumes to support capital planning and maintenance strategies. Whether documenting existing conditions, verifying dredging quantities, or tracking sediment changes over time, our data gives owners and engineers the confidence to make informed, defensible decisions.

Hydrographic surveys play a critical role in evaluating reservoirs, dams, intakes, culverts, and other submerged infrastructure. Schoel delivers detailed underwater mapping that helps identify sediment buildup, scour conditions, structural impacts, and changes in storage capacity. Our data supports safety evaluations, long-term asset management, and regulatory compliance, helping owners proactively address risks before they become costly failures.

Accurate underwater data is essential for environmental stewardship and permitting. Schoel provides hydrographic mapping for wetlands, streams, reservoirs, and lakes to support ecological monitoring, sediment transport analysis, and habitat assessments. Our surveys supply reliable data for regulatory documentation, restoration planning, and environmental compliance, ensuring projects move forward with clarity and accountability.

Underwater terrain data is a critical component of accurate hydrologic and hydraulic modeling. Schoel’s hydrographic surveys integrate seamlessly with engineering workflows, providing detailed bathymetric inputs for floodplain studies, stormwater modeling, and water resource planning. By improving model accuracy, our data enhances design reliability and strengthens long-term infrastructure performance.
