Statistical Evaluation of Historical Dike Failure Mechanism
Statistical evaluation of historical dike failure mechanism The failure mechanism of flood protection dikes includes physical (geotechnical, seepage) processes leading to a dike breach. An awareness of the failure mechanism is required directly in dike stability calculations and indirectly for risk calculations. Statistics of historical data indicate among others the distribution and frequency ...
متن کاملProbability of dike failure due to uplifting and piping
A methodology is presented for determining the probability of dikes failing due to uplifting and piping using directional sampling. The study concerns one dike section in the lower river area of The Netherlands. For this dike section, the three most important random quantities are: the North-Sea water level, the river Rhine discharge, and the critical head in the event of uplifting and piping. ...
متن کاملVirtual Dike: multiscale simulation of dike stability
We present a Virtual Dike simulation module developed as a part of a flood Early Warning System (EWS) for the UrbanFlood project. The UrbanFlood EWS is a distributed system that analyzes sensor data received in real-time from flood defenses (dikes, dams, etc.) and simulates dike stability, breaching and flood propagation. The aim of the Virtual Dike module is to develop an advanced multiscale m...
متن کاملStatistical investigations into isiZulu intonation
We study the relationship between lexical tone and measured values of fundamental frequency for several word classes in isiZulu, based on objective measurements from recordings of three speakers. For nouns and adjectives, both in isolation and in sentence context, a relatively invariant pattern of fundamental frequencies is observed. This observation is in apparent conflict with the range of to...
