Inshore Hydrographic Surveys
Hydrographic and Bathymetric surveys are undertaken on reservoirs, lakes, rivers and canals for construction (e.g. marinas), flood capacity or monitoring. By utilising the latest sonar, robotic or global positioning technology (GPS), we can quickly establish the exact river bed level of any waterway, irrespective of size, shape or depth, with millimetre accuracy.
Data can be supplied in either a 2 dimensional or 3 dimensional CAD or Genio format to assist in visualising the sub surface ground topography and, in addition, volumetric analysis can be undertaken, to calculate storage capacities or rates of silt deposition. When undertaking river surveys, cross sections can be generated and data submitted in either hard copy, CAD or spreadsheet format, for subsequent analysis using flood modelling software.
In addition to a client base of local authorities and statutory authorities, we are providing this service on an increasing basis for private developers, who need to know the impact of any proposed development, when sited near rivers or on potential floodplains.
