Summary: The study reveals that the power system on the U.S. West Coast is vulnerable to climate change, resulting in increased electricity demand and altered timing of hydropower production, impacting prices and reliability. Risks for the Pacific Northwest primarily lie in changes in streamflow, while California is mainly influenced by summer air temperature changes, particularly extreme heat events. The potential impact of altered hydropower production in the PNW on summer power deliveries to California is modest, with future extreme heat in California expected to have a stronger influence on prices and reliability in the PNW.

Summary: Wave runup estimates are crucial in erosion and overtopping models, but are often limited by incomplete knowledge of surf and swash bathymetry. This study extends an empirical model relating runup to wave spectra by including an effective mid-surfzone slope, beta(eff), and finds that setup and infragravity runup depend more strongly on beta(eff) than on foreshore beta(f). By considering both beta(eff) and beta(f), the accuracy of the empirical model is improved.

Summary: A wave resource characterization was conducted for the southern coast of Alaska using a 32-year hindcast analysis, identifying the Aleutian Archipelago as having the most abundant wave energy resources in the region. Statistics for wave energy parameters were calculated using the SWAN model and aggregated at 20 km from shore to quantify the incident wave power regionally. By evaluating resource hotspots located 1 km from shore, Alaska was confirmed to be a promising location for wave energy development.

Summary: Understanding the causes of coastal flooding is crucial for protecting communities and ecosystems in the context of global warming and extreme weather events. Cities in developing countries, such as Saint Louis in Senegal, are particularly vulnerable to coastal flooding. By analyzing data, we identified several neighborhoods in Saint Louis that are at risk of flooding, especially the low-lying river mouth plain. Sea level rise is the main factor contributing to increased flood risk.

Summary: This study uses observations and climate model simulations to explore the changes in hurricane intensification near the US Atlantic coast. The results show that there has been an increase in the mean hurricane intensification rate over the past 40 years along the Atlantic coast, while no significant change occurred near the Gulf coast. Climate models suggest that the storm environment and hurricane intensification near the Atlantic coast will continue to enhance in the future.

Summary: The study shows that North Pacific oceanic variability plays an important role in precipitation changes over the U.S. West Coast, with stronger (weaker) precipitation anomalies during warm (cold) phases. These anomalies are particularly pronounced in Northern and Central California during winters and in Baja California during summers. The changes in precipitation are primarily modulated by alterations in water vapor flux, which are directed towards (away from) the coast in winters (summers). These flux anomalies are mainly driven by large-scale wind changes associated with the atmospheric response to strong ocean surface temperature anomalies.

Summary: Slow-moving landslides, important landscape shapers and dangerous natural hazards, were investigated using satellite radar imagery to reveal their spatial distribution and geologic controls. The study found that these landslides are influenced by bedrock lithology and vertical land motion, with certain rock types and uplifted hillslopes showing higher occurrence and larger size. The results suggest that satellite radar imagery can effectively uncover slow-moving landslides and their occurrence and characteristics can be anticipated from vertical land uplift and bedrock lithology.

Summary: This study presents a new Performance-based Atmospheric River Risk Analysis (PARRA) framework, which adapts existing concepts from risk analysis and engineering to assess the flood risk caused by atmospheric rivers (ARs). Through a series of analyses in Sonoma County, USA, the PARRA framework demonstrates its utility in understanding extreme flood events and its potential for evaluating future events or system changes. By linking physically based models, this framework provides a probabilistic result that quantifies the uncertainty in the underlying system states.

Summary: Sea level rise and coastal floods are disrupting coastal communities worldwide, impacting critical urban systems like transportation. The closure of low-lying coastal roads and highways due to floods can lead to travel delays and increased accident risks. Quantifying the disruption of the urban traffic system by floods presents challenges, but implementing three corrections can improve the accuracy of identifying flooded roads and assessing flood impacts on urban traffic systems.

Summary: Understanding wave transformation in marsh vegetation canopies is crucial for assessing nature-based shoreline strategies. This study investigates the challenges of accurately modeling wave dissipation in coastal marshes and proposes a new dimensionless parameter to represent the canopy drag coefficient (C-D). The study finds that uncertainties in vegetation measurements lead to variations in C-D expressions, and suggests using the Cauchy number (Ca) as the more appropriate parameter for larger waves.

Summary: This paper extends the non-hydrostatic wave-flow model SWASH to account for the influence of a depth-uniform ambient current on wave dynamics. The model's ability is verified by comparing predictions to results from linear theory, laboratory experiments, and a spectral wave model. The extended model accurately captures current-induced changes in the wave field and simulations of wave dynamics in the presence of strong opposing currents.

Summary: Sandy-muddy transitional beaches (SMT-Beaches) are a type of coastal formation consisting of upper sandy beach and lower mudflat. This study examined the morphological characteristics of SMT-Beaches and the mechanisms of the formation of sandmud transition (SMT) boundary. Field surveys were conducted on SMT-Beaches in South China Coasts and a new equilibrium profile function for SMT-Beaches was developed. The function demonstrated good performance and improved accuracy compared to traditional methods. It was also found that sediment characteristics differ on both sides of the SMT boundary, with clay-to-silt grains increasing seaward.
