Summary: Tidal inundation is a major driver of intertidal wetland functioning, with differences in inundation characteristics between mangroves and saltmarshes depending on wetland microtopography and site-specific tidal regimes. Understanding these contemporary dynamics can help support wetland response to sea-level rise and restoration practices.

Summary: Climate change induced sea level rise (SLR) is a major challenge for estuarine management worldwide. This research used an idealized hydrodynamic approach to analyze the tidal range dynamics of 25 real-world estuaries, providing insights into estuarine response to SLR-induced tidal variations. The findings show that the estuarine tidal range dynamics change depending on their present-day tidal range patterns, with SLR increasing the tidal range in some estuaries and moderately increasing or slightly decreasing/increasing it in others. This approach can be useful in assessing the impact of SLR in estuaries and guiding evidence-based management approaches.

Summary: This study estimates the inundation of stormwater infrastructure along the US Atlantic coast using high-tide flooding on roads as a proxy. The results show that a large portion of stormwater infrastructure is inundated, affecting over 2 million people and occurring frequently.

Summary: This study investigates the impacts of historical landscape changes and sea-level rise on tides and high tide flood (HTF) frequency in Jamaica Bay, New York. Results show that a century of landscape alterations increased the tidal range by about 20% and the historical shift in tidal frequency is mainly associated with reduced damping at the inlet and increased tidal reflection. The decrease in surface area has a minor influence on tides, but the geomorphic influence significantly increases vulnerability to sea-level rise.

Summary: Sea-level rise is causing an increase in coastal inundation events, which can now occur solely due to tides reaching higher levels. Quantifying the role of sea-level rise in modulating the risk of coastal inundation is important, and a conceptual model and practical methodology have been proposed for tide-only inundation statistics. Incorporating this emerging natural hazard into coastal risk assessment frameworks will allow for better coastal management and planning strategies at local and national levels.

Summary: Sea level rise increases flood frequency caused by forces like spring tides or storm surges. However, future flooding may be driven only by astronomical tides due to the evolution of global ocean tides. An inaction method is introduced to accurately extract tidal components and analyze the long-term trends and spatial evolution of tides along the East Coast of the United States. The results show upward trends in most sites with M-2 exhibiting the most significant rise in North Carolina.

Summary: This article introduces the characteristics and improvements of the Floodwater Depth Estimation Tool (FwDET). Through optimization analysis and extensive comparison analysis, the sensitivity and optimal parameter settings of FwDET were discovered. The research results are of great reference value for floodwater depth estimation.

Summary: Coastal flooding, specifically high-tide flooding, is a growing concern for low-lying coastal cities in China. This study analyzes and assesses the frequency and impacts of high-tide flooding along the China coastline using tide gauge records. The results show an increasing trend in high-tide flooding frequency and cumulative loss ratios, and indicate that future sea-level rise will lead to more high-tide flooding events in China.

Summary: Remote sensing is crucial for understanding coastal wetland ecosystems, but tidal inundation affects the reliability of remote sensing-based models. To address this issue, we developed the Flats index to identify and filter flooded pixels. We also demonstrated innovative applications of the index in detecting flooding frequency and patterns.

Summary: This paper presents a retrieval algorithm for flood inundation mapping using Global Navigation Satellite System-Reflectometry (GNSSR) data. The algorithm uses a simple dielectric model to retrieve fractional inundation from an observation of reflectivity, requiring parameterizations of soil surface and water roughness as well as ancillary soil moisture data. By comparing the CYGNSS inundation maps with other surface water data from the Amazon, Mozambique, Mali, and Australia, sources of uncertainty in the CYGNSS inundation maps and possible reasons for discrepancies between the inundation retrievals are identified.

Summary: The scientific community has made significant efforts in simulating flooding conditions, but the current models still lack accuracy and reliability. It is suggested to adopt an approach that considers various factors and enhance understanding of flood generating mechanisms. Developing innovative earth system modeling frameworks and conducting rigorous studies can provide opportunities to improve flood prediction and mapping.

Summary: Sea level rise is leading to an increase in high tide flooding in coastal communities in the United States. However, accurate prediction of high tide flooding on a monthly-to-annual basis is currently lacking in most regions. This study presents a novel probabilistic modeling approach to predict the daily likelihood of high tide flooding using relative sea-level rise, tide predictions, and climatological non-tidal residuals. The results demonstrate that this approach has skillful prediction capability at many locations, with increasing accuracy as sea level rises.

Summary: Understanding patterns of species coexistence is a fundamental challenge in ecology, and the physical environment plays an important role in influencing patterns of biotic interactions and dispersal. We examined how floodplain forest communities varied in terms of their functional diversity and ecological strategies across regional and local gradients of flooding. Our results indicate that community assembly patterns are not solely determined by landform type or position, but are influenced by interactions between flood regimes and landform position over multiple spatial scales.
