EurOtop Live, challenging researchers and practitioners to improve EurOtop.Access to PC-Overtopping for prediction of overtopping for dike-type structures, although based on EurOtop (2007).Videos that show overtopping discharges and overtopping wave volumes for various wave conditions to guide the user in estimation of allowable wave overtopping.Access to databases and Artificial Neural Networks for prediction.Downloads of the present and older versions of the EurOtop Manual.In the future, other predicting neural networks may also become available. The ANN and both databases are available for free and links are given on the website. ![]() It is based on the large EurOtop-database, extended from the CLASH database, that contains more than 13,000 tests on wave overtopping. In parallel with this manual an Artificial Neural Network, called the EurOtop ANN, is available to predict mean overtopping discharge for all kind of structure geometries, given by a number of hydraulic and geometrical parameters as input. The old calculation tool has therefore been removed from the website and is not available as a tool covering this new manual. Unfortunately, no funds could be raised to update the web-based Calculation Tool with the new formulae in the present manual. With the first manual in 2007 an online Calculation Tool had been developed to assist the user through a series of steps to establish overtopping predictions for: embankments and dikes rubble mound structures and vertical structures. Further discussion identifies the different methods available for assessing overtopping, such as empirical, physical and numerical techniques. A chapter on hazards gives guidance on tolerable discharges and overtopping processes, including videos on overtopping discharges. The manual defines types of structure, provides definitions for parameters, and gives guidance on how results should be interpreted. The methods in the manual can be used for current performance assessments and for longer-term design calculations. The manual is intended to assist coastal engineers analyse overtopping performance of most types of sea defence found around the world. The manual includes case studies and example calculations. The Overtopping Manual incorporates new techniques to predict wave overtopping at seawalls, flood embankments, breakwaters and other shoreline structures.
