river surveys
Flood and Water Surveying
At Tri-Tech we have undertaken many river surveys across the country. By using the latest surveying technology we are able to survey watercourses safely and efficiently, so our clients obtain a reliable service. We provide surveys in various formats including CAD, PDF and CSV. This data then can be used for river / channel modelling.
Some of our services include:
- Flood alleviation surveys of floodplains and doorstep levels.
- Flood defence surveys and flood level contour chasing.
- River and stream sections, including hard and soft bed levels, as well as topographic survey of the river or stream.
- Bridge, tunnel and culvert surveys; creating a topographical survey, point clouds and elevations of structures.
We create individual Risk Assessments and Method Statements for each river survey to ensure each site is surveyed safely and that the client gets the most out of our time on site.
If you have any queries regarding river surveys, simply get in touch.

Land and Engineering Surveyors
topographical surveys
Tri-Tech work for a variety of different clients on different projects, and we pride ourselves on delivering accurate, efficient, cost effective surveys ensuring our clients receive the best possible product.
utility mapping
Using the latest equipment, we can provide the location of underground services in either 2D or 3D. We use state of the art Ground Penetrating Radar and Electromagnetic Location to assist your project when service avoidance may be a potential issue on site.
monitoring
Is there any movement? That is the question that is asked before and during any monitoring scheme. That is the reason we undertake monitoring, to check for movement.
laser scanning
For mass collection of accurate survey data then nothing beats scanning. Using 3D laser Scanners the surveyors can capture millions of points per second with the creation of a PointCloud.
volumetric analysis
We specialise in the analysis of a scheme’s volumetrics at any point in time. Be it Tender, Prestart, Monthly, Weekly, or Final.
