Topographic & Bathymetric Surveys
Our survey team are highly experienced in undertaking topographic surveys (RTK-GPS and total station) to gather precise and accurate spatial data. cbec also has a high specification bathymetric surveying capacity, using a ‘Hydrone’ remote controlled craft with echo-sounding capability to permit safe and efficient data collection from deeper or less accessible areas of water bodies.
Together, these surveying methods provide us the capacity to survey in a wide range of environments, including river channels, floodplains, lochs/ lakes/ reservoirs, estuaries and near-shore coastal areas.
cbec’s fluvial geomorphology team routinely conduct spatially referenced inventories to identify river form and all factors that are likely to influence that form.
We utilise the latest GPS-enabled tablet mapping technology to perform fluvial audits, employing a bespoke methodology that we have developed internally and which is adaptable to the needs of individual projects and different environments.
cbec staff has extensive experience of a wide range of sediment sampling methodologies, including ‘Wolman-walk’ pebble counts, volumetric/ grab sampling, bedload sampling, suspended load sampling and facies mapping.
This data is crucial for many design applications and, in particular, those that consider sediment transport processes.
Water Level and Water Quality Monitoring
For tidal and fluvial environments, cbec utilises our own water level recorders (pressure transducers) to collect water level measurements (often for the purposes of discharge gauging or hydraulic model calibration).
We also have specialist equipment for the long-term monitoring of water temperature, dissolved oxygen (DO), turbidity, conductivity, pH, contaminants and nutrients.
To support cbec’s hydrodynamic and water quality modelling, our team will design and implement monitoring stations for collection of meteorological data (e.g. precipitation, air temperature, wind speed, solar radiation, atmospheric pressure).
