I like to do a bathymetric survey to get a contour of the lake. With the limitation of the budget, may I know the suitable instruments that required to do this survey?
I am looking for a model of waterborne bathymetric drone (equiped with single-beam or multi-beam echo sounder) for the survey of highly turbid rivers and lakes and others complex aquatic bodies (drained rivers, ponds, shallow water) in tropical regions. Is somebody can provide me internet address of manufacturer? (speed : 5 m/s, jet propulsion) Thank you very much Jérôme
