Using echo sonar with specialist craft and software we can provide a 3D Digital Terrain Models (DTMs) model of river and lake beds to what every grid intervals required.

Cross sections through rivers for the use in flood studies can be generated at whatever interval requested, tidal levels and times and dates can also be recorded at high or low levels.
