Project summary

Edit project overview to modify the project summary.


Model the effects of altering the two flow control structures with a view to sending more low flows down the natural channel and taking excess flow downs the two culverts when water levels rise. The Beverley Brook natural channel only takes 20% of the flow during normal flow rates, which impacts the geomorphology, silt carrying capacity and habitat value of the brook downstream of the flow control structures.
