Andrew has project managed a restoration project on behalf of a well-known house builder. This involved designing bank and bed stabilisation techniques using vegetative techniques and natural materials. The key element of this project is linkage with landscape architect specialists within Jacobs and supervision of the Contractor (Five Rivers).
Andrew was responsible for the design of a river restoration project on a tributary of the Lower Ialomita River in Romania. This involved a catchment geomorphological survey to identify likely causes of river erosion, including gravel mining and entrapment of sediment in a dam. The local problem (leading to floodplain erosion and threatening a landfill site) was ascribed to previous channel straightening and mainstream downcutting. This potentially catastrophic erosion was rectified by a scheme involving a series of check weirs.
