Abstract: Flood discharge has been selected as the main theme of the Question 94 in the 24th ICOLD Congress. There are four sub-themes. This article focuses on the newly achievements and technologies on sub-theme one -- evaluation, revision and selection of extreme and design flood. The aim is to give a guideline to the engineers who are interested in this field. Some main features on this sub-theme from the papers in Q.94 are given. It shows that the revising and upgrading design flood has been emphasized by more countries. Some new numerical models or methods are developed based on long-term hydrological data sets and combinations of hydrological and hydraulic module. The design flood under abnormal conditions, such as climate change, dam break flood and rainstorm flood in extreme dry area, has become a new research subject.

Key words: extreme flood, design flood, evaluation, revision
