Alden’s Environmental and Engineering Services group is widely recognized as being highly effective in resolving flow and fisheries related environmental issues associated with FERC licensing and NPDES project permitting.
Our scientists and engineers have designed and evaluated numerous types of fish protection systems for water intakes as well as upstream and downstream fish passage facilities at dams and hydroelectric facilities. In addition to optimizing biological performance, the Group specializes in resolving O&M problems associated with intake screening such as debris management, icing, siltation, and head loss using a multidisciplinary approach combined with physical and computational flow modeling and testing.
