Summary: This study analyzed how the dual-aquifer configuration of atolls controls the temporal dynamics of groundwater flooding caused by storm surges. The results showed that the shallower the Thurber discontinuity and the higher the KP value, the higher the maximum water depth in the freshwater swamp on the atoll during the storm surge and the longer the flooding duration. Accurate information on the dual-aquifer configuration is necessary to evaluate the potential risk of groundwater flooding on atolls accompanying storm surges. Groundwater flooding caused by storm surges substantially contributes to cyclone-driven flooding on atolls and should not be neglected in flood predictions.

Summary: Non-perennial streams, comprising over half of the global stream network, have significant impacts on downstream water quality. Aridity is a major driver of stream drying globally, but the complexity of drying patterns in headwater streams may be influenced by topographic and subsurface factors. Groundwater residence times and contributions to streamflow were found to have a poor relationship, suggesting that old, deep groundwater pathways are not enough to sustain surface flows. Topography only explained about 30% of the variability in seasonal flow permanence, and there was no correlation between seasonal drying and down-valley subsurface storage area. Future studies should focus on pairing spatial observations of subsurface properties with seasonal flow permanence observations.

Summary: In this study, the spatiotemporal variation and underlying mechanisms of wetland landscape patterns in the arid and semi-arid region of the Yellow River were explored. The results showed that the floodplain wetlands became more fragmented and migrated towards the northeastern part. The operation of the Longliu reservoirs and ice flooding were found to have significant impacts on the wetland landscape patterns. However, land use changes did not have an impact on the spatiotemporal changes of wetlands.

Summary: Despite water shortages and infrequent rainfall, recent floods in arid and semi-arid areas have shown that flooding tends to be severe and life-threatening. However, flooding in these areas is poorly understood, and there are unique challenges in managing it. Therefore, it is important to develop a comprehensive understanding of Flood Risk Management (FRM) difficulties and needs in these regions.

Summary: Since 2000, declines in riparian ecosystem health and water use have been observed in the U.S. portion of the Lower Colorado River (LCR), primarily attributed to a loss of green vegetation. Indicators such as EVI2 results, daily evapotranspiration, and PAM ET losses showed a consistent downward trend, reflecting the decline in riparian health on the U.S. side. These declines are driven by a loss of healthy riparian plant-cover, with implications for biodiversity, wildlife habitat, and ecosystem services.

Summary: Rivers in arid regions rely on flow from upstream wetter regions and experience high transmission losses in downstream flows. This study presents a methodology using satellite remotely sensed actual evapotranspiration estimates to partition these losses. Applied to the floodplain of Cooper Creek in central Australia, the results show that 82% of transmission losses occur on the floodplain, 13% in the riparian zone, and 5% from open water in the river channel and waterholes. This method can be applied to other data-poor arid river systems.

Summary: Microbial-induced carbonate precipitation (MICP) and enzyme-induced carbonate precipitation (EICP) are two bio-cementation techniques for ground improvement. This study investigated the behaviors of MICP and EICP treated sand specimens under wetting-drying, freezing-thawing, and elevated temperature conditions. The results showed that EICP treated specimens had lower resistance to wetting-drying and freezing-thawing cycles due to the presence of unbonded or loosely bonded CaCO3. High temperatures led to significant mass loss and reduction in CaCO3 content. A multi-objective evolutionary genetic algorithm (GA) was used to predict the unconfined compressive strength (UCS) of the specimens.

Summary: Living walls are widely used in commercial buildings, but maintaining healthy plant growth on these systems poses challenges. This study found that plant selection is more important than substrate or irrigation regime selection. Additionally, the location of the plants on the wall and irrigation volume significantly affect the plants' dry weight. Specifically, plants grow taller on the upper section of the living wall. It is recommended to pay attention to plant location and irrigation water supply on different positions of the living wall.

Summary: The optimal strategy for solving the Richards equation numerically depends on the specific problem, particularly when using GPUs. This study investigates the parallel performance of four numerical schemes on both CPUs and GPUs. The results show that the scaling of Richards solvers on GPUs is influenced by various factors. Compared to CPUs, parallel simulations on GPUs exhibit significant variation in scaling across different code sections, with poorly-scaled components potentially impacting overall performance. Nonetheless, using GPUs can greatly enhance computational speed, especially for large-scale problems.

Summary: Methods and algorithms for measuring stream surface velocities have been continuously developed over the past five years to adapt to specific flow typologies. The free software ANDROMEDE allows easy use and comparison of these methods with image processing capabilities designed for measurements in natural environments and with unmanned aerial vehicles. The validation of the integrated algorithms is presented on three case studies that represent the targeted applications: the study of currents for eco-hydraulics, the measurement of low water flows and the diagnosis of hydraulic structures. The field measurements are in very good agreement with the optical measurements and demonstrate the usefulness of the tool for rapid flow diagnosis for all the intended applications.
