Streamlining river groynes: Laboratory experimentsin schematised geometry under submerged flow conditions

Groynes are hydraulic structures commonly applied in the Dutch rivers. Depending on the water depth, groynes can be emerged or submerged. When a groyne is emerged, it has two main functions: maintaining the water depth in the main channel and preventing the river from eroding its bank. When the discharge in the river increases, the groynes...

Preliminary design of a flood abatement control zone (ZAC) in the region of Murcia, Spain

The coastal area of the Murcia region in Spain experiences more frequent and more intense flash floods caused by inland heavy rainfall due to climate change. This results in high water levels in towns and cities, leading to risk of loss of life and many financial damages. Currently the region is vulnerable, because there are no hydraulic...

Financial feasibility of large-scale adaptation strategies for future SLR in northern Europe: NEED vs dike reinforcement

The effects of climate change are felt all around the world. An increased sea level goes hand in hand with an increased risk of flooding. To combat this, the coastlines must be reinforced to withstand future sea levels. However, repeatedly reinforcing coastlines to keep up with the sea level rise (SLR) could prove extremely costly. An...

The missing link in adaptive delta management: Insights on the potential of pumps in reducing flood risk under sea level rise and adaptive social learning to improve decision-making in the Rhine-Meuse estuary

Decision-makers in low-lying coastal zones are confronted with uncertain developments around flood risk.These drivers are surrounded by large uncertainties, which requires delta management to be adaptive. This research offers insights about adaptive delta management for the Rhine-Meuse estuary from three perspectives: a physical, a socio...

Return Level Analysis of Hanumante River using Structured Expert Judgment: A reconstruction of historical water levels

Like other cities in Kathmandu Valley, Bhaktapur faces rapid urbanisation and population growth. Unsafe, new settlements are partly located at the floodplains and the government lags behind in implementing proper land-use policy to control unrestrained settlement. The rivers are not only constrained by uncontrolled settlements, but also by...
