Darshana Dassanayake  who is originally from Sri Lanka and received his Masters from UNESCO-IHE, is presently a Research Associate and PhD candidate at LeichtweissInstitut, Technische Universität, Braunschweig, Germany. His paper addresses the increasing use of Geotextile Sand Containers (GSCs) and the lack of proper guidelines available for the design of GSC structures based on sound scientific data. To remedy this situation, Mr. Dassanayake and his colleagues at the university, under the supervision of Prof. Dr.-Ing. Hocine Oumeraci, have been conducting a series of experimental investigations and using numerical modelling to better understand the effect of GSCs on hydraulic stability and to develop a computational tool and simple formulae to determine this.
