Review of research of hydro-geomorphological processes interaction

The interaction of hydro-geomorphological processes is a nature phenomenon universally observed. Revealing of the quantitative relationship between the two processes is the long-term goal of hydrologists,which also is one of the important tasks listed in the new International Hydrological 10-year PUB(Predictions in Ungauged Basins) . The paper discusses the basic ideas and the main characteristics of statistical synthetic methods,as well as physicsbased methods that establish the quantitative relationship between the two processes. For more than a century,especially over the past 30 years,the geomorphology-based hydrological methods developed by international scholars are commented on. The author's contributions to the subject in recent years are also highlighted.
