Summary: Climate anomalies and human activities have increased the frequency of extreme hydrological events in wetlands, posing greater survival pressure on waterbirds. Therefore, accurately predicting the impact of this phenomenon on waterbird habitat suitability is crucial. This study used flood duration index (FD), enhanced vegetation index (EVI), and waterbird GPS tracking data to examine the response of goose distribution probability to hydrological variations in Poyang Lake. By building an overwintering geese habitat suitability index (HSI) and analyzing the effects of drought and flood on goose habitat, the research provides valuable insights for floodplain wetland hydrology management and waterbird conservation.

Summary: This study focuses on the phenomenon of flash floods under arid climate conditions in Gabes, Tunisia, by simulating historical peak flows and recent flood hydrographs using the HEC-HMS model. Calibration of the model based on statistical evaluation criteria resulted in good simulation results, which can be valuable for 1D and 2D hydraulic modeling to simulate water level variations during rainfall events and identify floodable areas.

Summary: This study assesses the adverse impacts of flash floods on holy sites and urban areas in the Wadi Mehassar basin. The rapid alterations in topography and lack of hydrometric stations in the study area pose challenges for assessing flash flood hazards. ArcGIS, ERDAS Imagine, and WMS were used to process geological and hydrological data, while mathematical hydrologic and hydraulic models were employed to simulate flood characteristics. The results showed that 44% of the total area was at risk of flash floods, with 5.4% classified as high risk, 13.3% as medium risk, and 81.3% as low risk.

Summary: The Atchafalaya River Basin, the largest forested wetland in the contiguous US, has experienced changes in hydrologic connectivity due to dredging and channel erosion. This study analyzed stage/discharge relationships, hydroperiods, discharge distribution, and channel cross-sections to find that much of the floodplain no longer receives sufficient discharge, resulting in stagnancy and hypoxia in the wetland. The confinement of discharge to a large channel also limits the system's ability to respond to sea-level rise and subsidence.

Summary: This paper used a coupled hydrologic-hydraulic model to study the impact of flash floods and urban waterlogging on urban flood processes. It found that rainstorm patterns have similar effects on flash flood hydrographs and urban surface inundation indicators. The combination of flash floods and urban waterlogging amplifies the effects of rainstorm patterns on surface inundation, especially in areas with high water depths. Different district topographies respond differently to flash flood propagation, resulting in a unique impact of rainstorm patterns on the spatial distribution of inundation lag time. Furthermore, flash floods dominate the total volume of inundation and increase the spatial connection of surface inundation between different locations. The findings of this study are important for managing urban flood problems.

Summary: This study proposes an integrated and systematic framework to assess the impact of urbanization on flood characteristics in Hangzhou, China. The results show that rapid urbanization has led to an increase in runoff volume and inundation volume, highlighting the significance of water body area in influencing flood characteristics.

Summary: This study analyzes the flash flood that occurred in Badajoz, Spain in November 1997 using the numerical code Iber+. The runoff of the river basin was simulated based on precipitation data, providing an accurate representation of the flood event. The simulation results align with field data and eyewitness testimonies. Various scenarios were analyzed, revealing that the blockage of bridges was the main cause of the catastrophic flood.

Summary: Flood mapping is crucial for identifying vulnerable areas, assessing impacts, and creating mitigation plans, but official flood hazard maps are lacking at the national scale in the EU. To address this issue, researchers propose a new flood model called RESCUE, which combines geomorphological analysis and simplified hydrologic-hydraulic modeling to provide simple and reliable large-scale inundation estimates. Despite limitations, the model shows promise and may serve as an effective tool for preliminary hazard assessment.
