The influence of deviating conditions on levee failure rates

This study introduces a method for assessing the annual failure rate of levees based on information from historical floods, while also considering the return period of these past events. Also, an approach has been developed to quantify the influence of deviating conditions on failure rates. The presence of deviating conditions at failed and...

Retrofitting Stormwater Ponds to Infiltration Ponds: A framework for the City of Cape Town

Cape Town is a city with over four million people and a growing population. Due to three consecutive dry summers as a result of climate change, a growing population and an increased per capita water demand, the city’s main water supply was nearly depleted. Cape Town depends for 98% on surface water stored in dammed reservoirs, which is...

A Bayesian hindcasting method of levee failures applied to the Breitenhagen slope failure

Hindcasting of past levee failures enhances insights in the performance and vulnerability of levees. The scarcity of field evidence makes identifying the cause(s) of failure difficult. Under these circumstances, multiple scenarios and model choices are possible to characterise and to model the failure. This paper shows how probabilistic...

Floating Homes Philippines: Multidisciplinary project

All around the world floods are a growing problem. Dealing with high water levels in residential areas is of great importance. The delta area of Macabebe, in the Manila Bay, has to cope with daily flooding, caused by the river and the sea. Groundwater is pumped and used for local industry, causing land subsidence and worsening the problems....

Forensic analyses and hindcasting of the Breitenhagen levee failure

The hindcasting of levee failures can provide valuable information about levee strength, strength models and dominant factors that contribute to failure. It is however not always clear how and why a levee failed as evidence (such as detail subsoil composition) is not present anymore.
