Abstract:
... Rainfall-induced surge waves in rivers are still today considered as an elusive and non-realistic phenomenon that has continued to mystify researchers and practitioners alike since the kinematic shock theory introduced in 1955. This is mainly due to scarce sightings of real cases, as well as physical and numerical uncertainties and sporadic calculations. In order to overcome such indefiniteness, a ...

Abstract:
... The Huaihe River Basin is located in China’s north-south climate transition belt, where massive droughts occurred in history. To comprehensively capture how climate extremes have behaved in the past, this paper analyzed the trend, change point, and periodicity of drought at multiple spatial-temporal scales based on the Standardized Precipitation Indexes (SPI). And the historical simulation experim ...

Abstract:
... The Lowest navigable water level (LNWL) is an important indicator used for navigation design to balance the relationship between navigation safety and economic benefits of a waterway. However, it is a challenge of accurately estimating LNWLs due to the nonstationary characteristics of observed water level data series. In this study, a comprehensive framework was developed for handling this issue. ...
