Great achievements of check dam construction on the China's Loess Plateau have been gained; however, the flood incidents on check dams have been frequently reported for the past decades. To migrate the breach risk of check dams due to floods, the main advances in the flood migration techniques achieved by the authors' research group are reviewed.

No PFAS were detected in major Philippines rivers despite reported increases in the Asia-Pacific Region. Sampling programmes typically focus on populated regions and a small number of compounds so may present an incomplete picture of global PFAS trends in rivers.

AquaVar is a decision support system (DSS) developed for water resource management in the French Mediterranean Var watershed. The results obtained during the first 5 years of use under operational conditions are shown. Lessons are drawn, covering topics such as DSS modularity, evolution, data positioning, technology, and governance.

The Kuye River Basin has experienced a rapid depletion of groundwater due to the increased coal production. In this study, by introducing the empirical equations derived from the three zone theory in the coal mining industry in China as a boundary condition, a calculation model was developed by coupling the soil and water assessment tool and visual modular three-dimensional finite-difference ground-water flow model (SWAT-VISUAL MODFLOW). The model was applied to several coal mines in the basin to quantify the groundwater impact of underground mining. Preventing surface subsidence due to underground mining can help protecting the basin's groundwater.

This study evaluates the flood frequency and susceptibility of the Haora River basin in Tripura, India, using the Log-Pearson Type III (LP-III) and Gumbel Extreme Value-1 distributions. The LP-III model was identified as the most suitable for estimating peak discharges, while flood susceptibility mapping, integrating 16 thematic layers through the Analytical Hierarchy Process, revealed that 8% of the area is highly susceptible to flooding. These findings highlight the need for targeted flood management interventions in the basin.
