Summary: The MIKE 11 rainfall-runoff model and MIKE 21 overland flow model were successfully coupled in the MIKE FLOOD platform to simulate flood discharge in the Gin catchment. The study found that land use change, particularly the expansion of forest area, can significantly reduce flood formation. These findings emphasize the importance of preserving forest cover and pervious areas to mitigate flood risks.

Summary: The study demonstrates that environmental DNA (eDNA) analysis can be a powerful tool to estimate population abundance of aquatic macroorganisms. By integrating knowledge of the processes governing eDNA distribution with numerical hydrodynamic models, a Bayesian inference of a generalized linear model can be used to estimate population abundance. The method was shown to provide comparable population abundance estimates to traditional methods and can also identify sources of exogenous eDNA input.

Summary: The hydro-ecological impacts of 40 UK Climate Projections 2018 scenarios on a restored lowland England river floodplain are evaluated using a MIKE SHE / MIKE 11 model. The scenarios show a decline in annual precipitation for 60% of cases, except for small declines at the central probability level. All probability levels except the most extreme show an increase in potential evapotranspiration. River discharges, floodplain inundation, and water table levels are reduced, with larger declines seen in the central probability level. Climate change also affects the vegetation communities, favoring those less tolerant of wet conditions.

Summary: Microbial communities play essential roles in aquatic ecosystems, and mathematical models along with advances in molecular biology tools are crucial for studying their composition and dynamics. However, models focusing solely on metabolic processes have limitations in aquatic ecosystems, as they fail to simulate hydrodynamic processes which can significantly impact microbial community composition and functions. Therefore, incorporating hydrodynamics into microbial models is vital for a more in-depth investigation.

Summary: The external nutrient loading significantly affects large shallow lakes, and the study found that high river input of permanganate values influences chlorophyll-a levels in Lake Taihu. Reducing the inflow concentration of permanganate during spring can inhibit algal growth, but the extent of reduction varies among rivers and lake zones. There is still a relatively high risk of algal blooms occurring in the main regions, particularly during autumn when inflow pollutant concentrations increase rapidly.

Summary: This study analyzes the performance of AW3D30, ASTER GDEM, and SRTM in tsunami modeling. The results show that ASTER GDEM underestimates tsunami inundation areas and flow depth values, and should not be preferred. On the other hand, SRTM and AW3D30 yield results that are similar to the LiDAR reference, making them suitable for tsunami modeling at the test site.

Summary: This article argues for improved conservation of freshwater ecosystems by assigning explicit values to river sections and wetlands, aiming for no further harm to the commons. The need for improved conservation is driven by the global deterioration of biodiversity and ecosystem services, increasing demands on water and land resources, and climate change. The article proposes a straightforward approach to spatial conservation rating using hydrogeomorphic typology and expert elicitation, and illustrates the approach using the Burdekin River catchment in Australia.

Summary: This study investigates the occurrence and abundance patterns of fish larvae, juveniles, and adults in the lower reaches of a short, deeply incised coastal river in the Australian Wet Tropics. The research finds that most species exhibit peak larval and juvenile abundance during the benign dry season, but some diadromous species show peak abundance in tidal riverine/estuarine waters during the wet season. The results highlight the importance of seasonal hydrology and habitat characteristics in influencing the life-history strategies and abundance variations of larval fish in tropical rivers.

Summary: Machine learning (ML) and deep learning (DL) methods have gained popularity in flood inundation modeling across river basins. DL models have shown better accuracy compared to traditional ML approaches. However, ML/DL models lack the incorporation of expert knowledge in modeling flood events and the lack of benchmark data to evaluate model performance poses a challenge in developing efficient models for flood inundation modeling.

Summary: This study uses Monte Carlo simulation and bootstrapping methods to estimate flood frequency and associated uncertainties in ten river catchments in eastern Australia. The results show that three-parameter distributions provide consistent estimation of confidence intervals, while two-parameter distributions show biased estimation. The study also emphasizes the difficulty in flood frequency analysis, as different probability distributions perform quite differently even in a smaller geographical area.

Summary: Considerable investment has been made in grazing land management in Australia's Great Barrier Reef catchments to improve off-site runoff and water quality. This study analyzed an 18-year monitoring data set in the Burdekin catchment, Australia, using a systems modelling framework. The findings show significant differences in function between B. pertusa pastures and native tussock pastures, with implications for monitoring and management strategies. The study also contributes to the calibration of the GRASP pasture grazing systems model for B. pertusa sites, allowing for better representation and assessment of these landscapes.

Summary: Limited information is available on the ecology of planktonic invertebrate assemblages of small tropical lowland rivers, despite zooplankton being a vital resource for larval fish. This study focused on the spatial patterns and temporal dynamics of invertebrate zooplankton in the lowland section of a short coastal river in the Australian Wet Tropics over a 25-month period. The results showed that the zooplankton assemblage was influenced by downstream distance, salinity, incised nature of the river, perennial flows, slack waters, wet season floods, and estuarine incursion. The dynamics of zooplankton in this river differ from the typical pattern of tropical floodplain systems.
