Kai, C. (author)Coastal zones which are known as the interface between continents and oceans are vital and important to human beings because a majority of the world's population live in such zones (Nelson, 2007). Coastal systems are among the most dynamic and energetic environments on earth and they are continuously changing because of the dynamic interaction...report 2009

Modelling of Cohesive Sediment Transportation, Deposition and Resuspension in the Haringvliet Mouth.Qinghua, Y. (author)In the Dutch coastal zone, where the marine environment is characterized by shallow depths and highly energetic hydrodynamic conditions, the cohesive sediments, or mud, play an important role in the local morphology. For instance, mud deposits and high concentrations of suspended particulate matter (SPM) occur frequently, especially during...report 2006

Boers, M. (author)DEEP SAND EXTRACTION ON THE NETHERLANDS CONTINENTAL SHELF (NCS) In the Nota Ruimte (=National Spatial Strategy) the Dutch Government has announced to allow for deep sand extraction on the NCS, where former legislation only allowed for extraction till a depth of 2 m below the initial seabed. This new legislation has been worked out in the ...report 2005

Shi, Y.B. (author)The Feiyun River, with a length of 203 km and a catchment area of 3252 km2, is one of eight rivers in Zheijiang Province (see fig.1-1), China. It flows into the East China Sea in Shangwang of Ruian City. The source of Feiyun River is at Xialing located in the border between Zheijiang and Fujian Province. The tidal influence can reach up the...report 2003

Anonymous, A. (author)In studies of flow structures on single-thread meandering rivers, secondary currents have been shown to have a large influence on the morphological development of meander bends. Until this joint study between FAP 24 and the University of Nottingham, UK, there had been few similar studies carried out on the influence of secondary currents on...report 1996

Tomohiro, S. (author)When bank protection works are constructed along an eroding outer bank, it is often observed that the bed along the outer bank becomes substantially deeper, sometimes causing the failure of the bank protection works themselves. Despite our awareness of this deepening phenomenon, its causes and quantitative estimation is still a matter of...report 1996

Kranenburg, C. (author)A derivation is presented of a general cross-section averaged model of longitudinal dispersion, which is based on the notion of the advection of tracer particles. Particle displacement length and particle travel time are conceived as stochastic variables, and a joint probability density function is introduced to arrive at an integral advection...report 1996

Sieben, A. (author)In this report, some classical and new simplifications in mathematical and numerical models for river morphology are compared for conditions representing rivers in mountainous areas (high values of Froude numbers and relatively large values of sediment transport rates). Options for simplification are summarized based on time scale of hydrographs...report 1996

Sieben, A. (author)This report focusses on discontinuous behaviour of hydraulics and morphology in rivers. The varying widths, slopes and bed levels that can be observed in mountain rivers can induce rapid, or discontinuous changes at a short lengthscale. When present, these discontinuities have a major impact on changes in water and bed levels during floods. In...report 1995

Sieben, A. (author)The ability of describing and predicting hydraulic and morphological phenomena in mountain rivers is limited, partially due to the limits of deterministic approaches where stochastic effects in sediment supply and water inflow are extremely significant, and partially due to the very specific conditions that can be observed in mountain rivers,...report 1994

Sieben, J. (author)Present knowledge on fluvial processes in mountain rivers should be expanded to enable the development of projects dealing with mountain rivers or mountain-river catchment areas. This study reviews research on hydraulic and morphological features of mountain rivers. A major characteristic of mountain rivers is the variability of the hydraulic...report 1993
