second. • Earthworks: Design swales leading to one or more stormwater retention ponds on the agricultural land on the flood plain between the Gosforth Nature Reserve and Golf Club to retain and treat the surface water drainage from the Killingworth-Forest Hall-Longbenton catchment which is currently discharged directly into the Ouseburn at Salters Ln allotments. Draw annotated profiles of these swales and ponds in line with, and perpendicular to the water flow direction. Develop a plan for the related site investigation and earthworks that minimizes the amount of soil being moved on/off the site. Design criteria: Your design of the swales and pond should be informed by the Ciria SuDS manual (provided on Canvas).
