This paper presents a hydraulic and morphological analysis of the Lower Jamuna in Bangladesh with a focus on two key bifurcations that are important for stabilization of the Lower Jamuna reach. We used ground measurements, historical data, multispectral satellite images from various sources as well as numerical models. We carried out hydraulic...

The Dutch River Waal, a branch of the Rhine, has been trained for centuries to mitigate the effects of ice-jams and improve navigation. The works, started in 1850, involved river straightening and narrowing by a series of transverse groynes. Besides fulfilling their goal, the groynes also created the need to raise flood protection works and...

Side channels are commonly constructed to reduce the flood risk or to increase the ecological value of a river. Such artificial side channels generally aggrade. We categorize the development of side channels based on the sediment that is deposited in these channels. Based on this categorization, we determine the main mechanisms that affect their...

Rivers have been trained for centuries by series of transverse groynes. This generally results in damages to their ecosystems as well as in undesirable longterm morphological developments. We analyze here the possibility to train rivers in a new way by subdividing their channel in parallel channels with specific functions with longitudinal...

To maintain a navigable channel and improve high-flow conveyance, engineers have recently proposed constructing longitudinal training walls as an alternative to the traditional transverse groynes. However, previous work has shown that the system of parallel channels created by a longitudinal training wall might be unstable in rivers with...

Rivers have been trained for centuries by channel narrowing and straightening. This caused important damages to their ecosystems, particularly around the bank areas. We analyse here the possibility to train rivers in a new way by subdividing their channel in main and ecological channel with a longitudinal training wall. The effectiveness of...

Alternate bars in rivers and streams develop as a result of differences in length scales involved in the adjustment of flow and sediment transport to irregularities of the bed. The amount of field evidence supporting theoretical insights is highly limited. Here, we present results from a large-scale field experiment in a 600 m long straight...

Humans have utilized water resources for millennia by modifying natural river courses and such interventions have greatly influenced not only river flows and sediment fluxes, but also the overall river morphology. Situated in the Nepal's eastern Ganges region, the braided Koshi River is unique among the other rivers, because of the high...

There are plans for the construction of a multi-purpose dam in the White Volta River near Pwalugu in northern Ghana. The reservoir that will be formed should be beneficial for hydropower generation, irrigation and fishery. Up to now there has been no research into the morphological consequences of the creation of this reservoir. In this study...

Rijkswaterstaat Limburg heeft de taak om in 2020 70% van de Maasoevers natuurvriendelijk te hebben ingericht. Waar mogelijk worden de huidige oevers omgevormd tot natuurvriendelijke oevers waardoor een groot deel van de oevers in de komende jaren van karakter zal veranderen: van strakke, versteende oevers naar meer natuurlijke land-water...

One of the branches of the Paraná delta is the Paraná de las Palmas River. This branch doesn’t have the biggest discharge but has the most navigation. The situation in the Paraná de las Palmas isn’t without problems though; the river banks show erosion over the whole length of the branch. This erosion has been investigated by the following...

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...

This thesis examines the morphological changes of non-tidal meandering rivers at the spatial scale of several meanders. With this purpose, a physics-based mathematical model, MIANDRAS, has been developed for the simulation of the medium-term to long-term evolution of meandering rivers. Application to several real rivers shows that MIANDRAS can...
