Hoffmans, G.J.C.M. (author)Het doel van het handboek ontgrondingen is een antwoord te geven op ontgrondingsvraagstukken zoals een ontwerper van waterbouwkundige constructies die tegenkomt. Verschillende deelstudies worden voor het afronden van dit handboek uitgevoerd. Het verifiëren van ontgrondingsformuies staat centraal in deze studies. Hier is de voorspellingskracht...report 1995

Gronewald, G.J. (author), Duncan, W.W. (author)This is a progress report on the Homer Spit Beach Erosion Study. Information is presented regarding the rapid acceleration of the erosion processes due to the subsidence of the Homer Spit during the 27 March 1964 earthquake. The effect on existing groins both before and after the quake are discussed. Immediately after the quake, emergency...report 1965

Cornish, B.A. (author)With the aid of a grant from the Water Research Foundation of Australia, the Water Research Laboratory has undertaken an investigation into surface treatments for small farm dams Vegetal cover with natural gr asses and low cost soil and bitumen admixtures are under study. As a preliminary to laboratory and field testing, a survey of available...report 1965

Zhao, G. (author), Visser, P.J. (author), Peeters, P. (author)Embankment breaching is a composite process coupled by hydraulic processes and sediment transport processes. Erosion is the link in the interaction between breach flow and embankment material. Surface erosion starts in the initial breach phase and triggers the initial damage of the embankment. As the surface erosion develops completely, the...report 2014

Gerritsen, F.A. (author)This report describes the design and implementation of the Delft Image Processor DIP-1. In this pipelined image-processing computer, a number of storage and processing modules which operate concurrently and synchronously (hardware floating-point ALUs and multiplier, conversion table and cellularlogic table) may be interconnected in a...report 1982

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

De Wit, P.J. (author)A research project was carried out at the Delft University of Technology in order to study the interaction between waves as weil as a current and a muddy bed. For this purpose several experiments were made on two artificial clays, namely China Clay and Westwald Clay. The results of the experiments on China Clay were reported by De Wit (1994). In...report 1994

(author)Model studies formed a basis for investigating the hydraulics of bywash spillways for farm darns When constructed in natural earth such spillways are trapezoidal in cross section The surface of the spillway needs protection from scour and this protection is usually in the form of grass. These tests extended to variations in spillway geometry and...report 1966

Ribberink, J.S. (author), Van der Sande, J.T.M. (author)The problem of aggradation in a river due to overloading is tackled with a mathematical model consisting of a set of one-dimensional (in space) basic equations in which the water motion is assumed to be quasi-steady and the sediment transport is determined by local conditions. Analytical solutions are presented of a linearized simple-wave model,...report 1984

Hoffmans, G.J.C.M. (author)Scour is a natural phenomenon caused by the flow of water in rivers and streams. Scour occurs naturally as part of the morphological changes of rivers and as result of structures man-made. Several types of scour can be distinghuished. Experience has shown that due to sand or flow slides or micro instabilities at the end of the bed protection,...report 1993

Verhagen, H.J. (author)Because dunes protect a large part of The Netherlands against coastal flooding and inundation, it is vital to guarantee the strength of these natural sea defenses. Besides sea defense, dunes have other functions. Sandy shorelines and dunes are frequently eroded. A legal framework has been developed that guarantees the required safety-level of...report 1990
