Biotechnical Riverbank Rehabilitation

Synopsis:

The webinar will describe 2 actual case studies at Malaysia and Hong Kong, for Biotechnical Riverbank Rehabilitation - the use of plants to stabilize and restore riverbanks. Biotechnical & Bioengineering Techniques offers a viable and sustainable alternative to traditional “hard surface” drainage channel engineering solutions under certain conditions. It is a major paradigm shift from the traditional “rapid discharge” concept where rainwater is quickly intercepted and efficiently conveyed by smooth concrete-lined drainage systems to rivers and discharged to the ocean. It has been established that this “rapid discharge” process has accounted for much downstream scouring and a history of eroded riverbanks with devastating results and “unnatural” aesthetics. The primary advantage is to stabilize riverbanks, restore habitat and resist bank scouring will be discussed. The follow projects on river channel restoration and “green” revegetation of concretelined river channel section will be presented, challenges discussed, solutions learnt and shared: a) Urban…
