A generic life cycle applies to crevasse splays in non-degradational fluvial systems, typically ending in healing and abandonment. Crevasse-splay channels adjust to a graded equilibrium profile through proximal erosion and distal deposition, with their distal termini acting as a (prograding) local base level. When proximal incision advances to...

In some internally-draining dryland basins, ephemeral river systems terminate at the margins of playas. Extreme floods can exert significant geomorphological impacts on the lower reaches of these river systems and the playas, including causing changes to flood extent, channel-floodplain morphology, and sediment dispersal. However, the...

The downstream peak discharge increase during hyperconcentrated floods in the Yellow River has been attributed to bed erosion, roughness reduction and floodplain effects. While great improvements have been made on the nderstandings of the roles of bed erosion and roughness reduction, the effects of floodplain remain poorly understood. Here, as a...

Computers are increasingly used in the simulation of natural phenomena such as floods. However, these simulations are based on numerical approximations of equations formalizing our conceptual understanding of flood flows. Thus, model results are intrinsically subject to uncertainty and the use of probabilistic approaches seems more appropriate....

The Middle Zambezi, host to a rich biodiversity, is located in the central part of the Zambezi River Basin which covers eight Southern African Countries. The area is located downstream of three hydropower schemes. In the last decades, the floodplain riparian tree, the Faidherbia albida, vital for the local wild life, has shown a worrying...

Until recently, governmental organizations played a dominant and decisive role in natural resource management. However, an increasing number of studies indicate that this dominant role is developing towards a more facilitating role as equal partner to improve efficiency and create a leaner state. This approach is characterized by complex...

Previous experiences have shown that the implementation of planning policy does not always lead to the originally intended territorial management outcomes. This issue is particularly crucial when policy ideas, institutions, models and programmes are transferred into places with different cultural settings without adaptations (Knieling and...

At high water stages obstacles in the floodplains of a river contribute to the flow resistance. In particular the elevated vegetated parts are expected to play an important role. The objective of this study is to estimate and parameterize the form drag due to vegetated oblique weir-like obstacles. An experimental study has been carried out in...

Research on lateral exchange of streamwise momentum between parallel flows in open channels has mainly been focused on compound channels composed of a main channel and a floodplain, on mixing layer development downstream of river confluences, and on partially vegetated channels. This study aims to establish the mechanisms responsible for...

Pilot projects are widely applied in water management. They can be used to test risky innovations at confined scale, but can also be used to delay policy decisions or to advocate a particular innovation. In this book the phenomenon ‘pilot project’ is explored both theoretically and empirically. A framework to analyse pilot projects is developed...

The debate on scale use in river management focuses primarily on the (lack of) fit between the biogeophysical and institutional systems. However, in this article we focus on the ‘subjective’ aspect of scale preferences in water governance. We apply an adapted version of the Integrated Scale Hierarchy for Rivers to determine the degree of fit...

Flume experiments and field observations demonstrating the effects of vegetation on river planforms are reported in literature, but numerical studies of these effects at the river scale are lacking. We investigated the effects of vegetation in a 2D morphodynamic model using submodels for flow resistance and colonisation of newly formed deposits....

This document presents a set of Best Practice Guidelines for road development and rehabilitation in the Mekong floodplains of Cambodia and Viet Nam. The guidelines are developed under the ‘Roads and Floods’ project1. The guidelines are based on the review of local practice, international experience, and case study results. They are intended for...

Inventory of heavy metals in the sediments of the Tisza was done. It showed accumulation of heavy metals and that the load moves downstream just like a flood wave. Simulating further pollution events showed that the agricultural threshold values might be exceeded threatening the agricultural production.

The FMMP is cooperating with WWF Living Mekong Programme, and three Delft Cluster institutes (UNESCO-IHE, Delft Hydraulics and Geodelft) to implement a 2 year 'Roads and Floods' project. The project aims at developing economically sound and environmentally friendly guidelines for the planning and design of roads in the Mekong floodplains of...

Since the Industrial Revolution, mankind has disturbed the natural functioning of river floodplains by a high input of contaminants in the environment. Riverine suspended matter is the most important source for elevated levels of contaminants in floodplain areas. Previous research mainly focused on processes affecting the distribution of...

Understanding the interactions between the ecosystem and the morphology of river floodplains, i.e. floodplain biogeomorphology, is becoming increasingly important in view of modern river management and climate change. There is a need for predictive models for the natural response of river floodplains to hydraulic measures and river...
