​We offer assessment of flow requirements for instream ecological habitats, including:
-
River habitat surveys
-
Instream flow/velocity/depth/habitat profiling
-
Physical HABitat SIMulation
-
Ecologically acceptable flow regime derivation
​
In addition, we are able to work closely with aquatic biologists and/or river engineers to offer more comprehensive assessments and solutions to improving river-corridor and instream biodiversity and ecological resilience.
ECO-HYDROLOGY
We have been involved in the pioneering of the ecology/hydrology interface in the UK since its earliest days in the late 1980s. Our staff developed the first Environmentally Acceptable Flow Regime in the UK (on the River Darent in Kent) and were involved in the first ever use of the PHABSIM computer model in the UK (developed by the US Fish & Wildlife Service to assess the influence of river flows on instream fish and macroinvertebrate physical habitats), including experimental field work, derivation of habitat preference curves for UK conditions, and undertaking the computer simulations.
