Probabilistic design and risk analysis for the Duong river dike in the Red River delta in Vietnam

Traditionally, the design of sea and river dikes in Vietnam is primarily based on a water level with a particular frequency of being exceeded. The frequencies of exceedence of design levels and governing discharge are widely regarded as constituting a standard for the safety of the region protected by the dikes and are interpreted in terms of...

Kosteneffectiviteit van maatregelen en pakketten: Kosten-batenanalyse voor Ruimte voor de Rivier, deel 2

This report is part 2 of the economic analysis of the project ‘Space for the Rivers’, which aims at improving the safety against flooding along the river Rhine. It is a Cost-Effectiveness Analysis (CEA) of proposed measures and packages. A method has been developed for evaluating measures and packages with more than one effect at the same time....

Load interdependencies of flood defences

In the Netherlands flood risks are often assessed by using a dike ring approach. This approach has, aside from many advantages, also some disadvantages. The main disadvantage is that, when zooming in on a small area, the effect of the system on that small area and vice versa, is or cannot be accounted for properly. Research has shown that for a...

Risk analysis on cascade breaching of the Tangjiashan landslide dam and two smaller downstream landslide dams

The 2008 Mw 7.9 Wenchuan earthquake triggered at least 257 landslide dams, most of which formed in series along rivers. The failure of an upstream dam could cause the failure of dams downstream one after another. The cascade dam breaching may result in sharp increase of flood and more serious damage downstream. This paper aims to analyze the...

Flood Risk Assessment & Investment Framework: A framework for flood risk reduction strategies in the Hollandsche IJssel

The Hollandsche IJssel is a river between Rotterdam and Gouda and is protected from the main river system in the Netherlands by a storm surge barrier. The Hollandsche IJssel experiences several problems: the storm surge barrier dates from 1958 and has a relatively low closure reliability; three quarters of the dikes have been rejected according...

Framework for assessing the performance of flood adaptation innovations using a risk-based approach

The application of risk-based approaches for the design of flood infrastructure has become increasingly common in flood management. This approach, based on risk reduction and reliability, is used to assess the performance of conventional interventions (e.g., flood defences and dams) and to support decisions regarding their implementation....
