Summary: The study found that basin slope and annual rainfall significantly influence the parameterization of scaling laws in hydrogeomorphic floodplain modeling. In semi-arid basins with low-gradient valley slopes, the scaling relationships are inconsistent in defining floodplains. Further research is needed to understand the applicability of these relationships.

Summary: Variance-based analysis is used to quantify the sensitivity of the output y to the input variables x. This paper focuses on the sensitivity analysis of correlated input variables using high-dimensional model representation (HDMR) to separate the structural and correlative contributions. The results show that HDMR and HDMRext successfully analyze the structural and correlative contributions of the model output and provide an optimal experimental design for parameter correlation.

Summary: A reliable index, called the Integrated Bioassessment Index (LIBAI), was constructed to assess the ecological health of floodplain lakes. This index considers multiple biological taxa and major stressors, and can effectively distinguish between urban and rural lakes. It can be extended and applied to other floodplain lakes, and the outcomes of health assessments for the eastern plain lakes in China help identify conservation and restoration priorities.

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 paper focuses on the analysis of the first tens of meters of the Martian subsurface using the SHARAD radar. It compares the use of different high-resolution DTMs for radar simulation, namely, from the HRSC onboard Mars Express and the CTX onboard MRO. The study shows that the HRSC DTM failed to reproduce the surface echo visible on SHARAD data, and also highlights the potential artifacts in optical DTMs that can complicate radar analysis.

Summary: This study introduces a two-way hydrological coupling model between land and river systems to investigate the impacts of floodplain inundation on land and river processes. By calibrating river channel geometry and developing a new inundation scheme, the simulation of inundation dynamics is improved. The results show that the two-way coupling modifies water and energy cycles globally and affects sensitivity in different climate regions.

Summary: The importance of transforming predictor variables to improve hydrologic forecasts, focusing on the frequency domain of the variables involved, was discussed in this paper. Wavelet-based approaches were presented as a means of transforming the variance associated with different frequency bands in each predictor variable. A stepwise variance transformation framework was proposed to facilitate transformations of the residual error from a given predictor variable conditioned on existing or pre-identified predictor variables, leading to better characterization of the response.

Summary: This study reveals the mechanisms by which hydrological gradient variations in wetlands affect biomass and carbon storage. It shows that wetlands with high-frequency wet-dry alternations have higher soil nutrients, plant dominance, biomass, and soil carbon content. The study also identifies positive correlations between wet-dry alternations and the relationships of soil nutrients-plant biomass-soil carbon and plant dominance-plant biomass-soil carbon. The concentrated effect of wet-dry alternations promotes plant growth and carbon input to the soil, thereby increasing soil carbon content.

Summary: This study uses LiDAR data and hydrologic modeling to assess the biophysical complexity and productivity of floodplain forests. The results show that inundation has direct effects on canopy cover and vegetation productivity, while vegetation structural diversity plays an important mediating role. The coexistence of vegetation layers in floodplain patches enhances aboveground productivity in response to flooding regime.

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 study applied data-driven models to predict runoff in the Russian River basin, California, USA, between 2010 and 2019. The results showed that long-short term memory and support vector regression models performed better than the artificial neural network model for hourly runoff forecasting, especially during the wet seasons. These data-driven models provide sufficient predictive capability and practicality for areas lacking observation systems.

Summary: This study proposes a deep learning approach as a post-processor to improve the predictive performance of hydrologic modeling. The proposed model utilizes a long short-term memory model with sequence-to-sequence structure to correct errors in hydrologic data and enhance runoff forecasting. Experimental results demonstrate that the model significantly improves the accuracy of runoff predictions compared to standalone hydrologic models.

Summary: This study examines the sediment storage and spatial heterogeneity in a montane river corridor after a wildfire. The findings suggest that wider portions of the river corridor with multithread channels have greater spatial heterogeneity, larger volumes of logjam backwater storage, and finer sediment storage. Despite significant turnover of sediment in the first runoff season after the wildfire, the cumulative sediment volume at monitored logjams reached 71% of the volume immediately after the fire. Vegetation recovery in multithread reaches was faster and more complete, contributing to overbank deposition. The results highlight the disproportionate importance of spatially heterogeneous river corridors in attenuating sediment inputs following wildfires.

Summary: Socio-hydrology has expanded the knowledge of the hydrological community by incorporating ideas and approaches from other scientific disciplines, particularly social sciences. However, there is still much to explore in terms of capturing human agency and combining different methods and disciplinary views from both hydrological and social sciences. This paper, based on the Special Issue Advancing Socio-hydrology published in this journal from 2019 to 2022, highlights the importance of understanding the multi-level nature of human decision making and applying an interdisciplinary multi-method approach to enhance the understanding of coupled human-water systems.

Summary: Previous studies have focused on racial and socioeconomic disparities in exposures related to flood events, but they did not differentiate between different flood types. This study compares social vulnerability, housing types, and housing tenure (rented vs owned) between two flood types-flash floods and slow-rise floods-across the Contiguous United States (CONUS). The results show that socially vulnerable populations are more likely to be located in areas prone to slow-rise floods. However, the hypothesis that they are also more exposed in flash flooded areas could not be confirmed. The assessment provides valuable insights into the impact of specific flood types on different populations and housing tenure, informing resilience and planning strategies at local and state levels.

Summary: Understanding the effects of wildfires on food webs, particularly in high-elevation areas, is a challenging task. This study found that wildfires can alter the structure and function of stream-riparian food webs, impacting benthic periphyton, aquatic macroinvertebrates, trout populations, and riparian spiders. While some aspects of the food web showed significant changes following the wildfires, others remained relatively resilient.

Summary: This study evaluated the future climate change impacts on physical habitat for the threatened Greenback Cutthroat Trout (GBCT) in headwater streams using field data and hydraulic models. Results showed reductions in both predicted streamflow and physical habitat under all future climate projections. Streams located at higher elevations with larger substrate and steeper slope were projected to experience more severe reductions in physical habitat. Step-pool streams may experience greater changes in available habitat compared to pool-riffle streams.

Summary: An analysis of geospatial data for almost 80,000 floodplain areas in the USA reveals that about 70% of these floodplains currently have poor floodplain integrity due to human activities. Despite the benefits of floodplain landscapes, they continue to be degraded at a higher rate than other landscape types. This research quantifies the impact of human activities on floodplain integrity and highlights the need for targeted restoration efforts in areas most in need of preservation.

Summary: Floodplains play important roles in ecological, hydrological, and geomorphic functions within river corridors. Flume experiments were conducted to investigate the influence of floodplain vegetation on bedform topography under different overbank flow depths. The results showed that both higher vegetation density and larger flows can increase bedform heterogeneity, suggesting that floodplain vegetation and natural hydrologic regimes can enhance stream habitat complexity.
