Effects of a deep sand extraction pit: Final report of the PUTMOR measurements at the Lowered Dump Site

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 ...

Physical Effects of Sea Sand Extraction / Fysische effecten van zeezandwinning

FRAMEWORK OF EXISTING POLICY Several Dutch policy documents are relevant with respect to sea sand extraction on the Netherlands Continental Shelf (NCS), ie: - the government directive on shallow mineral reserves SOD (Structuurschema Oppervlakte Delfstoffen= Master Plan Surface Minerals), - the regional directive on extraction at the NCS RON/MER ...

Secondary currents and morphological evolution in a bifurcated channel

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...

Morphological Changes due to River Bank Protection

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...

A dynamic/empirical model for the long-term morphological development of estuaries: Development of the model

Theoretical analysis on nodal point relations in 1D network morphodynamic models

Mathematical Modelling of 3D Coastal Morphology

The present lecture deals with models for situations in which the spatial dimensions cannot be separated according to the scales of the morphological processes. Rather common examples of such situations are the morphological evolution near structures (e.g, breakwaters), river outflows, tidal inlets, etc. But also in the absence of such distinct...

Impact of sea level rise on the morphology of the Wadden Sea in the scope of its ecological function (phase 1): Inventory of available data and literature and recommendations on aspects to be studied

Aspects of sediment- and morphodynamics of subtidal deposits of the Oosterschelde (Netherlands)

The present thesis consists of five articles, in all of which links are established between sedimentological aspects of sediments - mostly below the low-water 'line - in the Oosterschelde and either large- or small-scale morphological changes. Large morphological changes and associated movements of sediment which occur in the tidal system of the...

The history of the Dutch Coast in the last century

The aims of this paper are: 1. To publish some available coastal measurements and computations of more than local importance. 2. To investigate the influence of groynes in practice. 3. To investigate the motion of the gullies in the outer deltas. The following conclusions are drawn: 1. The gross littoral drift along the Dutch coast is of the...

Lecture notes on "The Role of Rivers to Mankind"

It is the task and target of River Engineering as a profession to provide all the tools for arriving at an optimum utilization of the potential resources, optimum in the sense of promoting the beneficial characteristics of the river and eliminating or at least checking the adverse qualities. To strive for this aim, there must be a scientific...
