Large scale embankment breach experiments in flume

Embankment breaching is a composite process coupled by hydraulic processes and sediment transport processes. Erosion is the link in the interaction between breach flow and embankment material. Surface erosion starts in the initial breach phase and triggers the initial damage of the embankment. As the surface erosion develops completely, the...

Evaluating Scour at Bridges - Fifth Edition

This document is the fifth edition of HEC-18. It presents the state of knowledge and practice for the design, evaluation and inspection of bridges for scour. There are two companion documents, HEC-20 entitled "Stream Stability at Highway Structures", and HEC-23 entitled "Bridge Scour and Stream Instability Countermeasures". These three documents...
