There are plenty of overlapping areas between nature and water (management). Eco-hydrological know-how is indispensable to gain sufficient insight into the function of possible interventions such as design works or water level management. Designing with the aim of restoring and creating nature values or species populations, is an area of specialism in its own right. Think for example of the importance of surface water and ground water models. Antea Group is broadly skilled in qualitative as well as quantitative eco-hydrological analysis. Ecological models in general are becoming more important, as they enable us to act in a more cost-efficient and responsible way.
