Characterize river systems and riverbeds in high-resolution

In river areas and environments around the world there is an increasing demand for characterizing the hydrogeology underlying rivers and estuaries. Knowledge about the interaction between river water and the groundwater in the river sediments can help to understand if the river receives water from its surroundings or leaks water to the groundwater. This interaction is important to understand.    

The geoscanner (FloaTEM on towed boats carrying a geoscanner), makes it possible to sail up the river and scanning the geological layers below the riverbed, such as the accumulation of fines at the bottom of a reservoir to permeable sand/gravel riverbed sediments that focus groundwater discharge. 

The measurements helps with mapping and to understand the river systems and the interaction between river water and the groundwater in the river sediments. The information is essential for river management, flood prediction, when understanding the groundwater-river interactions.
