Local river interventions, such as channel narrowing or side channels, are often necessary to maintain safety, ecology, or navigation. Such interventions have different effects on the river's bed morphology during periods of high- and low-discharge events. Mapping the bed-level variations for different discharge levels and understanding these...

The objective of this thesis is to assess the effects of climate change on the initial, transient and equilibrium response of mixed-sediment river. Climate change will cause changes to hydrographs, which in turn affects sediment transport capacity and thereby the river bed profile. In order to create a better understanding of the processes in...

What long ago started as a small fishing village, seeking refuge from the Romans, slowly evolved into the city of Venice that we know today. With its unique location came unique problems, most of which were related to the interplay between Venice and its lagoon. By severe measures in the past it has continued to withstand the test of time. <br/...

The Meuse river facilitates important socio-economic functions. In the light of Integrated River Management (IRM), the question rises whether these functions can be facilitated in future decades (until 2050) as well. The riverbed is expected to degrade over the coming decades, just like in the past century. On top of that, the discharge regime...

This experimental study is about the bed-load transport over inlet sills of longitudinal training walls. The focus is on the flow structures around the inlet: the shape, the processes and the effect on sediment transport. Groynes have been replaced by longitudinal training walls in an 11-km long pilot project to optimize training of the river...

Rapid hydropower development is taking place in the Mekong river, which is expected to change the natural river regime. Because of the ecological and economical importance of the Mekong delta, the effects of these changes could have large consequences in the delta area. This research focuses on the hydrodynamical processes and assesses potential...

Rivers respond to changes in their geometry or their controls in various ways and at a wide range of space and time scales. The response consists of changes in properties such as cross-sectional shape and area, slope, planform pattern, bed roughness and bed sediment composition. Usually, attention for the morphological impact of engineering...

The Nederrijn and Lek are presently dammed by three weirs, build in 1960 till 1970, which are located near the village of Driel, Amerongen, and Hagestein after which they are named. Weir Driel regulates the distribution of water at the IJsselkop for dammed conditions (discharges lower than 2350 m3/s at Lobith). A minimum discharge of 285 m3/s...

Occasional flows of the river Nyabage cause floods in the river valley, flooding bridges and buildings, amongst others a small hospital of MsF. The flow is a mixture of water and debris and causes severe damage. The report describes the phenomena and the damage in the area. Some proposals for improvements are given

It is possible to reduce flood risk in estuaries without having to drastically modify the river banks by levees or to block shipping routes and ecological flows by dams. ‘Storm surge barriers’ close off a river mouth at times of high sea water levels, but keep the river open during calmer times. ‘Moveable river flood barriers’ direct a river...

Over two-thirds of the Netherlands’ economy and half its population is below sea level. The Dutch government recently set out far-reaching recommendations on how to keep the country flood-proof over the next century given the likelihood of rising sea levels and river flows. This paper explains the recommendations, which are based on a gradual...

The current river management policy in the Netherlands is to give rivers more space, mainly by main channel widening and floodplain lowering. The aim is to reduce flood water levels and to create more favourable conditions for river ecology. However, the effect on water levels gradually disappears due to sedimentation and vegetation growth on...

Troost, S.T. (author)
In 2000 the Dutch government chose a new point of view for the Dutch rivers: “Room for the River”. This viewpoint is the basis for a new approach of high water protection in the Netherlands. Instead of strengthening and raising the dikes, solutions must be based on space and spatial quality. One of the suggested measures is the addition of...

The Fluvial design guide is aimed at professional staff engaged in the design process from the early stages of looking at alternative solutions through to the delivery of the outputs of design for the construction, maintenance, refurbishment or alteration of flood defence or land drainage assets. The guide is thus intended to be used by both...

After the disastrous floods in Bangladesh in 1987 the Flood Action Plan (FAP) was initiated. The FAP was a co-ordinated action to study the flood problems of Bangladesh. The Meghna Estuary Study (MES) was drawn up as a component of the FAP. The overall goal of MES is to ensure the physical safety and social security of the people living in the...

The subject of this study is the Feni River Closure Dam in Bangladesh, which was designed in 1983 and subsequently built in 1985. In this final report the influence is analyzed of advanced design methods, which have become available since 1983, on the geometric dam profile and sea side slope protection. For this purpose the Feni dam was...
