Hoan, N.T. (author), Booij, R. (author), Stive, M.J.F. (author), Verhagen, H.J. (author)The velocity and turbulence distributions of decelerating open-channel flow in a gradual expansion were measured using LDV equipment. The results show that the logarithmic law can describe the mean velocity in the bottom region well while the Coles’ law can be applied to the outer region. The shear velocity can be determined both by the...conference paper 2007

Lam, N.T. (author), Stive, M.J.F. (author), Verhagen, H.J. (author), Wang, Z.B. (author)Morphodynamics of a tidal inlet system on a micro-tidal coast in a tropical monsoon influenced region is modeled and discussed. Effects of tides, waves, river flows and system configuration on the inlet morphologies are investigated with the aid of process-based state-of-the-art numerical models. Seasonal and episodic behavior of the inlet...conference paper 2007

Hoan, N.T. (author), Booij, R. (author), Hofland, B. (author), Stive, M.J.F. (author), Verhagen, H.J. (author)The current research is aimed at finding a proper relation between flow forces acting on the bed and the bed response. To this end, experiments were carried out in which both the bed response (quantified by a dimensionless entrainment rate) and the flow field (velocity and turbulence intensity distributions) are measured. The three available...conference paper 2007

Tuan, T.Q. (author), Stive, M.J.F. (author), Verhagen, H.J. (author)Under effects of tropical cyclones, the coast is subjected to attack both by surge and wave from the sea and by flooding from the bay. These forces pose a serious breaching threat to natural sea-defence works such as barrier spits, barrier islands, lagoon barriers, etc. on the coast. Unintended breaching can be catastrophic, causing losses of...conference paper 2006

Lam, T.N. (author), Stive, M.J. (author), Verhagen, H.J. (author), Wang, Z.B. (author)Thuan An is a tidal inlet located in Vietnam in a tropical monsoon area. The inlet is very dynamic and variable under the influences of not only tides and waves from the sea but also flows and floods from upstream rivers. Therefore, morphodynamic behaviour of the inlet is very complicated and not well understood. Studies on inlet are also facing...conference paper 2006

Dijkstra, J.T. (author), Uittenbogaard, R.E. (author), Stive, M.J.F. (author)In many areas around the world, there is a large interest in the protection and restoration of aquatic vegetation, like eelgrass (Zostera marina), but little is known about the interaction of such vegetation with its environment. To improve this knowledge, a model has been developed that simulates this interaction between highly flexible...conference paper 2006

Tuan, T.Q. (author), Verhagen, H.J. (author), Visser, P.J. (author), Stive, M. (author)For management of coastal breaching hazards it is critical to be able to assess the potential of coastal barrier breaching as a result of wave actions during storm surges (wave overwash). This phenomenon is known as the breach initiation phase; the mechanisms behind this are not very well understood. In the present study, laboratory experiments...conference paper 2006

Stive, M.J.F. (author), Terrile, E. (author), Reniers, A.J.H.M. (author), Verhagen, H.J. (author)Threshold of motion of coarse particles under regular shoaling waves is studied. Experiments were performed to investigate the effects of bed fluid acceleration on coarse particle stability. By varying wave height, wave period and water depth combinations of similar peak orbital velocities and weak to strong intra-wave accelerations were created...conference paper 2005

(author)The present paper describes an analysis of the morphological integrityof the multiple channel system (MCS) of the Western Scheldt estuary. The tidal flats and surrounding ebb and flood channels form morphological cells, and the entire MCS can be schematized as a chain of such cells. The major ebb and flood channels have lost their one time...conference paper 2001

A comparison is made with aerosol produced in the surf zone as measured during EOPACE experiments in La Jolla and Monterey. The surf aerosol production was derived from aerosol concentration gradients measured downwind from the surf zone...conference paper 1998

Stive, M.J.F. (author), Nauta, T. (author)Projections are that Rotterdam, one of the worlds' largest harbours, will be in need of 1250 hectares of additional harbour area within the next 15 years. To meet this demand a substantial land reclamation ("Maasvlakte-2") is considered, which could provide 1000 hectares of new harbour areas and 750 hectares for nature and recreation.

Stive, M.J.F. (author), Baarse, G. (author), Misdorp, R. (author)The theme of the present discussion is to consider coastal observation needs in the broader context of a sustainable, integrated management response to coastal change. Thus underlining the notion that observations are an element of a more comprehensive process. We will therefore first explore the process of ICZM, and find that deficits in...conference paper 1996

Stive, M.J.F. (author), Capobianco, M. (author), Wang, Z.B. (author), Ruol, P. (author)We have formulated an aggregated-scale behaviour-model for the interaction between a tidal basin and its adjacent coastal environment, without adopting a priory assumptions about their independent dynamic equilibrium behaviour. Necessarily so, the model combines observations and findings resuhing from analogical model applications. The model...conference paper 1996
