This research focusses on assessing the impact of re-meandering on the reduction of the flood risk at the scale of a 1.6 km long reach (final length), in the context of a rural mid-catchment stream the size of the Eddleston Water a tributary of the Tweed River.Comparison of the changes between the former straightened channel and the new re-meandered channel is made by analysing the hydrological time series (2011-2020), comparing repeat channel topographies (2018 and 2020), quantifying the changes in the channel geomorphology, and modelling 2D flood extents and dynamics (HEC-RAS 6.0) for different sizes of flood events. Conclusions are drawn on how it is reducing the flood risk for a potential community located downstream from the re-meandered reach.

Projects in France: * Groundwater modelling: - Impact assessment of spoil waste disposal on groundwater contamination and feasibility study of containment works. - Unsaturated zone modelling to assess the impact of rainfall infiltration through infiltration trenches. - Impact assessment of a gravel pit on a river and a drinking water production site. - Impact assessment on the local hydrogeology and two associated surface water bodies of a new line of the underground subway in the north-east region close to Paris (project "Grand Paris"). * Regulatory impact assessment: - Impact assessment on a wetland caused by the construction works of a new underground level crossing. - Regulatory studies related to the French Water Law for abstraction boreholes and relief wells. - Impact assessment study on the geological risks and on the local hydrogeology and two associated surface water bodies of a new line of the underground subway in the north-east region close to Paris (project "Grand Paris"). Desk study following the groundwater modelling. - Regulatory study related to the French Mining Code assessing the feasibility and the sustainability of a geothermal field (24 probes, 196 m deep each). * Surface water: - Analysis of banks morphology of two rivers as part of the creation of a blue corridor. - Regulatory study related to the French Water Law to manage runoff water during the construction work of a new underground subway line. - Assessment of the storm water system for a local authority (4,000 pop.), design of the solutions to avoid further flooding.International Projects: - Identification of potential landfills for inert waste around 3 large cities in Haiti (2015). - Feasibility study of heat pumps as part of an eco-district project in Turkey (2013). - Benchmark of existing geothermal risk insurance schemes in some European countries, US and Japan (2013). - ESIA of the extension of Phnom Penh International Airport (2012).
