Comprehensive Watershed & Catchment Area Mapping

Every infrastructure project alters the natural landscape and affects local water movement. We map out vast geographical catchments using dual-frequency DGPS networks, high-density aerial LiDAR scanning, and satellite remote sensing data.

Boundary Delineation: Mapping natural watershed borders to determine exactly how much rainfall drains toward your project zone.

Stream Network Analysis: Tracing natural stream patterns and seasonal water networks to prevent accidental blocking or diverting of critical drainage lines.

Land Use Classification: Analyzing surface types (e.g., concrete surfaces vs. natural soil) to calculate precise runoff coefficients.

Flood Routing & Civil Hydraulic Design

Developing near coastal zones or low-lying floodplains requires robust flood protection structures. We execute advanced flood routing surveys that track how flood waves move across a terrain over time. Our detailed reports provide structural and civil engineering teams with the exact numbers they need—including peak discharge volumes and maximum high flood levels (HFL)—to size culverts, plan storm channels, and set safe building foundation heights.

Integrated Cross-Sectional (Ls & Cs) River Surveys

Bridges, pipelines, and retaining bunds crossing major rivers require deep riverbed data. We conduct precise hydrographic and bathymetric surveys to capture sub-surface riverbed shapes. We generate detailed Longitudinal Sections (Ls) and Cross Sections (Cs) profiles that allow structural engineers to calculate river scour depths, map sediment build-up patterns, and design long-lasting riverbank protection walls.

Urban Drainage Layout Design & Master Planning

Rapid city growth reduces open land, placing immense pressure on municipal storm drain systems. We assist municipal bodies and private master planners in designing high-capacity urban storm networks. By combining precise terrain elevations with decades of local rainfall data, we help design gravity-led storm networks that clear heavy monsoon rainwater quickly and eliminate urban waterlogging.

We understand Chennai's complex hydrology, from the Adyar and Cooum river basins to the critical water dynamics of industrial hubs like Sriperumbudur and Oragadam.

Our official credentials ensure that our catchment maps, flood risk models, and structural drainage reports carry the legal weight required for environmental clearances and government project approvals.

We eliminate manual fieldwork errors by deploying dual-frequency RTK GNSS receivers, precision echo-sounders for water-depth gauging, and industry-standard GIS and hydraulic modeling software.
