- Geotechnical investigationBoreholes, SPT/CPT, soil and rock characterisation for foundation design and dam safety reviews.
- Geophysical surveysSeismic refraction, electrical resistivity tomography, ground-penetrating radar for subsurface profiling.
- Topographic surveyDGPS-based topographic mapping with drone photogrammetry for difficult terrain.
- Bathymetric surveySingle-beam and multi-beam echosounder coverage of reservoirs, rivers and harbours. See our bathymetry methodology paper.
- GHG emission monitoringGreenhouse gas flux measurement from reservoirs and water bodies for climate impact assessments.
Why field data matters
A hydraulic model calibrated against assumed Manning's n is a guess in fancy clothes. We invest in field instrumentation precisely because every modelling brief downstream is only as good as the data feeding into it.
