Channel response of an engineered river to climate change and human intervention

Humans have intervened in rivers for centuries. River engineering measures have aimed at protecting populations against flooding, ensuring reliable and safe navigation, providing freshwater for drinking, domestic and industrial use, irrigation, and energy supply, and providing opportunities for recreation. All around the world, measures such as...

Developing a Model to Study the Climate Change Impact on River Bifurcations in Engineered Rivers

Climate change is responsible for global shifts in precipitation patterns and an overall in-crease in global temperatures. The transi-tions are anticipated to modify the river hydro-graph and sea level. The changes to the hy-drograph are also likely to influence sediment flux. These alterations imply shifts in both up-stream and downstream...

Centennial Channel Response to Climate Change in an Engineered River

Human intervention makes river channels adjust their slope and bed surface grain size as they transition to a new equilibrium state in response to engineering measures. Climate change alters the river controls through hydrograph changes and sea level rise. We assess how channel response to climate change compares to channel response to human...

Venice and the Lagoon: Two new visions

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/...

Assessment of the Current and Future Saltwater Intrusion Into the Cai River in Nha Trang, Vietnam

Assessing the functional performance of the Meuse river: The impact of bed developments and an altering discharge regime on future river functioning

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...

Development of a methodology to assess functional performance of the Dutch Rhine: A case study on the impact of autonomous trends and sediment management strategies

The summer and autumn of 2018 showed the negative effects of both low-flow conditions and bed degradation over the last century on the river functions of the Dutch Rhine. These resulted in record-breaking water levels, extreme low navigation depth and subsequently nautical problems. As climate change will increase the inter-annual variability of...

The economy-wide impacts of climate change and irrigation development in the Nile Basin: A computable general equilibrium approach

A multi-country, multi-sector computable general equilibrium (CGE) model is employed to evaluate the economy-wide impacts of climate change under the IPCC's A2 and B1 scenarios and existing irrigation development plans in the Nile basin. The study reveals that climate change adversely affects mainly downstream Egypt and to a lesser extent...

Climate Change Impacts on River Floods: Uncertainty and Adaptation

The modelling frameworks, which include greenhouse gas emission scenarios, climate models, downscaling methods and hydrological models, are generally used to assess climate change impacts on river floods. In this research, the uncertainty associated with each component of the modelling framework is analysed with particular reference to climate...

Hydrological Changes of the Irtysh River and the Possible Causes

Hydrological changes of the Irtysh River were analyzed concerning the changes of annual runoff and its distribution features within a year measured by coefficient of variation and concentration degree. Abrupt changes were detected by the heuristic segmentation method. Possible causes of the hydrological changes were investigated considering...

ACER: Developing Adaptive Capacity to Extreme events in the Rhine basin

Water managers in the Rhine basin are increasingly confronted with information on the impact of climate change and climate variability on the discharge regime of their river system. The river Rhine has a long history of flooding events that caused casualties and severe damage. The question remains whether measures that are currently implemented...

Climate change and water resources management - 4th Yangtze Forum

1 The Swiss Strategy for Adaptation to Climate Change (Probst Thomas, Hohmann Roland, Koellner-Heck Pamela) 2 Adaptation to Water-Related Disasters Caused by Extreme Weather Conditions (Takara Kaoru) 3 The Application of Macro Scale Distributed Hydrological Model in Runoff Simulation of JiaLingJiang River Basin (Junliang Jin, Guoqing Wang,...

Dredging history of the river Waal and expected future dredging works

Rijkswaterstaat is responsible for maintaining the fairway of the river Waal for navigation for more than a hundred years. In the past problem areas, which cause hindrance for navigation and block the fairway, were prevented with structural measures. Dredging was used as a last resort. In 2005 the desired fairway depth was increased from BRV -2...

Climate change and inland shipping

Although much attention is given to the consequences of climate change with respect to melting icecaps, starving polar bears, sea level rise and inadequate storm defense systems, there may be severe consequences for inland shipping too. Not only because of more frequent occurrence and longer durations of closed storm surge barriers, which may...

Effecten van klimaatverandering op de Waterkwaliteit in de Rijn en Maas

De waterkwaliteit van rivieren is het meest kritisch tijdens hydrologische extremen en onder hoge watertemperaturen. Uit verkennende studies naar effecten van klimaatverandering op de waterkwaliteit in de Rijn (Zwolsman & Van Bokhoven, 2007) en Maas (Van Vliet & Zwolsman, 2007) is gebleken dat er in het algemeen een verslechtering van de...

Das Eis auf den Niederländischen Flüssen und die Klimaänderung seit dem Jahre 1879

Study on the relation between climate change and ice cover in the Dutch rivers since 1879.
