For decades congestion levels around the world are rising. To properly incorporate the effects of congestion into strategic transport models, a shift from static capacity restrained towards capacity constrained and dynamic traffic assignment models has occurred. In this paper we focus on quasi dynamic assignment models (more specific: static...

The 10 km wide Jamuna river in Bangladesh is  one of the most morphologically active rivers in  the world, with bank erosion rates of up to 500  m per year (Mutton and Haque 2004). Such  extreme river migration in the center of  Bangladesh, one of the most densely  populated and impoverished regions in the  world...

Longitudinal training dams (LTDs) are  constructed in the River Waal in the  Netherlands. They are aligned parallel to the  river shore and divide the river into a main and  side channel. The existing groynes are  removed yielding more discharge capacity at  high flows. The side channel creates possibly a ...

Over the past centuries natural river banks have been transformed into banks with artificial revetments or sheet piles to protect them from erosion. Important river features for flora and fauna have disappeared and the ecological quality of the river reduced dramatically. Recently, the importance of the ecological function of rivers has been...

We experimentally tested the effect of a  largerange in helical flow intensity and  sedimentmobility on equilibrium transverse  slopes,which resulted in a function for slope  effectsdepending on bed state and  sedimenttransport mode, that deviates from  linearfunctions with sediment mobility in  literature...

Confluences are fascinating elements in river systems. The merging of tributary rivers produces complex hydrodynamics that can play an important role in sediment transport problems, ecological studies or the routing of a pollutant. If the two merging rivers originate from different regions they can have different characteristics. One such a...

Research into the Vertical Axis Wind Turbine (VAWT) has been progressing over the last few years due to
the large shift in design constraints for large floating offshore wind turbines by leveraging tools and experience
from research beginning in the 1970s and lasting until the HAWT established market dominance in the 1990s. The beginning...

Although many studies regarding bank erosion  and accretion can be found in the literature, it is  not common to find works studying the interaction  between opposite banks. Some existing  morphodynamic models describe bank erosion as  an event that depends on near-bank flow and bed  topography, as well as on...

An horizontal axis wind turbine placed in a free stream develops a wake behind its rotor. Inside this wake, complex vortical instabilities are developing and can lead to turbulent structures generation1 . In order to predict performances and loads of wind turbines in wind farms, it is essential to accurately characterize these wakes and their...

Recently, engineers propose longitudinal  training walls to replace traditional transverse  groynes. This new intervention is expected to  maintain a navigation route under low flow  conditions while not hampering flow  conveyance of the river channel. Navigation  occurs mainly in low-land river channels where ...

The drivetrain of most wind turbines currently being deployed commercially consists of a rotor-gearboxgenerator configuration in the nacelle. This abstract introduces the control system design and optimization for a wind turbine with a hydraulic drivetrain, based on the Delft Offshore Turbine (DOT) concept1 . This concept enables the connection...

For wind farm control, the current practice in industry is that every turbine has its own wind turbine controller that will optimize its own performance in terms of power output, load mitigation, and/or reference tracking. However, in several national American and European1 research projects, researchers from industry and academia have shown...

Challenging neighbourhoods in large cities most often lack social coherence. Meaningful social interaction between citizens in such neighbourhoods is needed to increase coherence, and games may be a means to this end. This paper reflects on the structure of a dedicated game design workshop with teenagers from 12 to 16 years of age designed to...

Sediment management measures are  becoming increasingly popular as they are  considered sustainable from both economic  and environmental point of view. For example,  aimed at counteracting river bed degradation,  sediment nourishments have been carried out  in the German reaches of the Rhine river while  a...

The Ribb River is one of the components of the  Blue Nile River system located in the North  Western part of Ethiopia. It drains to Lake  Tana, the source of the Blue Nile River. The  Ribb has a length of 130 km, with a catchment  area of 1,812 km2. The average yearly rainfall  of the catchment is 1300 mm, with...

This presentation will provide an overview of progress to date in the development of a system modeling framework and ontology for wind turbines and plants as part of the larger IEA Wind Task 37 on wind energy systems engineering. The goals of the effort are to create a set of guidelines for a common conceptual architecture for wind turbines and...
