Rankine Lecture: Design methods for geosynthetics used for erosion of channels and river banks
Speaker: David Shercliff, ABG.
JOINT MEETING with Yorkshire Geotechnical Group

refreshments from 6.00pm for 6.30pm start
The design of geosynthetics used in erosion control on river and channels has evolved over the last 50 years and much empirical experience has been gained. Geosynthetics filters have developed to meet the demands of an often harsh environment placed on a wide range of soils. Academic studies have developed an equally wide range of complex filter rules. However designers do not always have the luxury of time to mount a sophisticated soil investigation and then to select the ideal filter. This presentation seeks to offer some practical design rules and tables, including recently published geosynthetic selection tools published by the Dutch authorities. Reference is also made to the concept of a managed overtopping of embankments and the need for reinforced engineered vegetation.
