Van 't Woud, A.J. (author)Bij het doen van voorspellingen op lange termijn met morfologische modellen heeft men te maken met sterk variërende randvoorwaarden (b.v. golfhoogte, getij stroming). Als men bijvoorbeeld het jaarlijkse sedimenttransport in een gebied langs de kust wil bepalen moeten eigenlijk al deze variaties van de randvoorwaarden, in de berekeningen worden...master thesis 1993

Havinga, F.J. (author)The present report contains a description of an experimental program, as a follow up of experiments by v.d. Kaaij and Nieuwjaar in 1986, and Nap and Van Kampen in 1987. As in the second study, in the present study a particle sand diameter of D50 = 100 mu was used, so that the experiments of Nap and Van Kampen will be referred as "the earlier 100...master thesis 1992

Sloff, C.J. (author)The rivers on the slopes of the Kelud volcano in Indonesia are marked by steep slopes and fine sediment. Therefore often supercritical flow and large sediment transports occur. In this exploratory study a mathematical model has been developed for this type of rivers. The properties of this model are examined with an analysis of the...master thesis 1990

Tönjes, P. (author)The bed of some rivers partially consists of non-erodible layers. These non-erodible layers may become obstacles for navigation during the low-water period. To improve navigation development in the future, one can consider the removal of the non-erodible layers. To predict the morphological consequences due to these works, knowledge about the...master thesis 1989

Tilmans, W. (author)Sediment transport by waves in the direction of the waves in relatively shallow water. Het onderzoek naar zandtransport in meest algemene Zin kent al een ruime historie. In eerste instantie lag het accent hierbij op bestudering van het zandtransportverschijnsel onder invloed van een permanente stroom, zoals in rivieren en kanalen. Daarbij is in...master thesis 1989

Ohnishi, M.P. (author)Sediment transport causes morphological changes of coastal areas, and it is one of the most important objects in coastal engineering study. Recently, various experiments have been performed to investigate the sediment transport mechanism under a combination of waves and currents and to find the underlying relationships among various parameters...master thesis 1989

Nap, E.N. (author), Van Kampen, H.F.A. (author)Investigation to sediment transport rate in case of waves and currents, tests executed in the wave-current flume of the laboratory of Fluid mechanics of TU Delft. Sediment transport was measured using sand of 100 micron; comparison to similar tests with 200 micron sand.master thesis 1988

Van der Kaaij, T. (author), Nieuwjaar, M.W.C. (author)In many coastal, engineering problems the sediment transport plays a part. A transport gradient causes accretion or erosion. Various models, such as that of Bijker, Engelund and Hansen (van de Graaff and van Overeem, 1979) and Nielsen (1985) are available to estimate the sediment transport rate if the hydraulic and environmental conditions (wave...master thesis 1987

Marangoni, G. (author)In this report the sediment transport at Parachique, Peru, is calculated. This has been done in two different ways. First the Bijker method has been applied. This has been done by taking the significant wave height as representative for the wave spectrum and by chosing an equivalent wave height as representative for the significant wave height...master thesis 1985

Termes, A.P.P. (author)In order to predict waterlevel changes in rivers due to floodwaves and local bedshapes for navigation, the local behaviour of the riverbed should be known . In many cases the bed of 3 river consists of dunes, which propagate downstream due to the sediment transport along the dunes . In this report mainly the watermovement but also the sediment...master thesis 1984

Schepers, J.D. (author)In een modelgoot wordt door het golfschot naast een periodieke golf in het algemeen ook een stoorgolf opgewekt. Aangezien de voortplantingssnelheid van deze golven ongelijk is wordt door niet-lineaire interactie nog een golf opgewekt, de interactiegolf. Daardoor vertoont het totale golfbeeld een ruirntelijke periodiciteit die gekarakteriseerd...master thesis 1978

Schepers, J.D. (author)Er zijn door o.a. Vetlinga en Schepers proeven gedaan in een laboratoriumgoot ter bepaling van zandtransport in de voortplantingsrichting van golven onder invloed van die golven. Doel van deze proeven is om neer inzicht te krijgen in de opwoeling van het bcdemmateriaal aan de bcdem en op die manier in het zandtransportmechanisme . In al die...master thesis 1978
