Experimental work will include: (1) Hydraulic lab experiments conducted in controlled conditions to validate models for a variety of leaky barrier designs and materials in the new Novak Flume Research Facility; (2) In situ experiments: a number of types of leaky barrier will be trialled and monitored in a real channel – the Natural Green Infrastructure Facility. This unique site can mimic both rural and urban applications; (3) Possible case study sites: Wansbeck (working with National Trust), Weardale NFM demonstrator or Lustrum Beck NFM. These sites will allow a number of larger leaky barrier features to be instrumented and tested in rural environments. Mathematical modelling will be undertaking including: (1) Pond forensic modelling in which simple models are applied to mimic observations taken at the leaky barriers using water level recorders, velocity meters and cameras; (2) 1D/2D hydrodynamic models. Experimental results will to provide data to inform hydrodynamic models. The aim is to produce a 1D model that can capture the range of behaviour observed in experiments for a range of leaky barrier designs and materials. Full evaluation of the operation of the leaky barriers for a range of flows will help inform computational fluid dynamics models, which in turn will lead to better design criteria.
