river surveys
Land and Engineering Surveyors
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.
What is a River Survey?
A river survey is a type of hydrographic survey that involves measuring and mapping the physical features of a river and its surroundings, including its channel, banks, and adjacent land. River surveys are typically carried

setting out & site engineering
Bread and butter work for us! Having a strong relationship with many civil engineering companies we have a very strong team of Site Engineers and Engineering Surveyors working for us.
control network installation
At Tri-Tech we have vast experience in this field. Be it a large highway scheme or a private property we can advise on what accuracies are required from your control network depending on what work you are carrying out and the tolerances you are carrying this work out to.
uav mapping & aerial surveys
Large areas of ground can be covered capturing the most unbelievable detail which would just be unable to be recorded with traditional methods. Our clients have really seen the benefit of what UAV surveys bring to the table.
survey equipment hire
Being a leader in the Surveying and Engineering sector we have a fleet of modern survey equipment at our disposal which is second to none. We carry the latest GNSS Base Stations, GNSS Rovers, Robotic Total Stations, Laser Scanners, Digital Levels, and Dual Grade Lasers.
3d machine control
Machine control systems have been around for years now and Tri-tech have been utilising these systems from the very start. We realised the benefits of these systems early on when working with earthworks contractors.
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.
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.
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.
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.
