Hydraulic engineering requires a holistic approach. We understand the interactions, know the processes and pursue an interdisciplinary approach – from strategic planning to implemen- tation. Ultimately, we develop cus- tomized solutions that harmonise the human and environmental priorities in every situation.

We evaluate the characteristics All hydraulic engineering tasks of water basins, establish peak have their origins in hydrome- discharge rates, plot hydro- chanical interactions. graphs, and assess runoff and retention volumes to better On questions of hydrology and understand floods, bed load hydraulics, we aim to give expert processes and debris flows. answers and offer innovative tailor-made solutions: from Our employees also have in- rainfall-runoff calculations to river depth knowledge in the areas basin models, and from sediment of maintenance, area planning, transport to installation-specific
