Van der Meer, J.W. (author), De Wit, J.M. (author)More than six kilometers of rehabilitation works on sea defences at the Essequibo and West Deroerara coast of Guyana has been constructed within one year. This shows the fast construction of the riprap revetment design. The performance of the structure was good until the last month of construction when two slip failures occurred of a bout 100 m...report 1996

Yarde, A.J. (author), Banyard, L.S. (author), Allsop, N.W.H. (author)This report describes research to simplify and consolidate the prediction of wave action in reservoirs; to calculate wave induced discharges on embankments; and to extend work on blockwork and slabbing protection for dam faces presented by Herbert et.al (1995) in the companion report SR 345. The report should be used by engineers involved in the...report 1996

Pilarczyk, K.W. (author), Klein Breteler, M. (author), Bezuijen, A. (author)A summary of the theoretical and empirical knowledge of the stability of block-revetment structures under wave attack is given. This has been accomplished by selecting the very essence of the design formulas from (CUR/TAW, 1992/1994) and completing it afterwards with a database of results of large-scale model studies from all over the world....report 1995

Høeg, K. (author)P r e f a c e This book describes Norwegian and international experience and practice with the use of asphaltic concrete cores for embankment dams. The properties of asphaltic concrete can, within fairly wide limits, be tailored to satisfy specific dam design requirements. This is an important aspect and advantage of using bituminous cores in...report 1993

Ward, D. L. (author), Ahrens, J. P. (author)A series of physical model tests was conducted in a wave flume to study the effect of dynamic rubble protection in front of a vertical bulkhead. This rubbble berm revetment was placed in front of a bulkhead with stone size such that wave action would reshape the berm into an equilibrium profile. Profiles of the berm were taken before and after...report 1992

Klein Breteler, M. (author), Laboyrie, J.H. (author), Verheij, H.J. (author)Erosion of banks and dikes subjected to water motion can be prevented, for instance by application of cellular concrete revetment blocks. This type of revetment combined the merits of a closed block revetment and a slope revetment consisting of loose materials. Advantages are high permeability, high stability against wave attack and low block...report 1988

Klein Breteler, M. (author), Bezuijen, A. (author)The permeability of a layer of closely placed concrete blocks on a sublayer of gravel or sand without a geotextile has been investigated. The results indicate that the permeability of the blocks can be described as a combination of the permeability of the joints and the permeability of the the gravel just below the blocks. The permeability of...report 1988
