Mapping of a potential inundation from a 1% fluvial
event, UK
We have built up years of experience in the use of geographic
information systems (GIS) and remote sensing across a broad
spectrum of environmental projects, using the latest techniques and
software to ensure that our work is supported by the very best data
and analysis available.
We are skilled in interpreting and manipulating photogrammetry,
LiDAR, Synthetic Aperature Radar and ground survey data to create
digital terrain models, and we offer a multitude of skills in the
analysis and interpretation of geographic information
including:
- Flood assessment and hazard mapping: Assessment of flood
risk providing a consistent risk-based approach to sustainable
development
- Volumetric calculations: Creating 3D models and
calculating volume, including calculation of volumes of spoil from
dredging activities and cut and fill from embankments and
landfills, based on detailed topographic/bathymetric models
- Slope stability modelling: Calculation of stability of
slopes for both development potential and disaster management
- Groundwater modelling: Using geostatistical spatial
interpolation techniques to identify groundwater levels over large
regions
- Constraints and opportunity models: Using strategic
models to identify areas of development opportunity and
constraint
- Visual impact analysis: Development of 'visual
envelopes' using 3D topographic models for potential
developments
- Dam breach assessment: Using digital terrain models and
hydrodynamic modelling to identify flood hazard zones, their area
and depth and flow velocity
