Summary: Pluvial flooding in urban areas is a major cause of disaster loss in Canada, primarily due to overwhelmed drainage systems. Existing climate change adaptation programs have focused on managing the underlying factors of urban flooding, but attention to inflow and infiltration (I/I) has been limited. This paper provides a review of the impact of I/I on wastewater systems and urban pluvial flooding, based on extensive engagement with Canadian practitioners, and discusses issues related to private property involvement.

Summary: Rainfall's spatiotemporal variability plays a key role in catchment runoff and flood response. This study assesses the sensitivity of runoff and flooded areas to rainfall movement in the Kan catchment (Iran). The results show that rainfall movement affects the runoff response, with higher velocities resulting in higher peaks and faster onsets of runoff. The direction of movement also plays a role, with storms moving along the average direction of the stream resulting in higher peaks and flooded areas. The influence of rainfall movement is also modulated by hyetograph structure and location within the drainage network.

Summary: Land consumption and climate change have led to increased natural disasters in urban areas. The Sustainable Development Goals of the European 2030 Agenda aim to improve ecosystem protection and resilience to natural disasters worldwide. This study investigates the effects of Land-Use and Land-Cover Changes (LULCC) on flood mitigation and agricultural production ecosystem services in the metropolitan area of Rome. The results show a negative change in ecosystem service supply due to urbanization and a reduction in agricultural land.

Summary: This study focuses on the impact of different rainfall patterns and intensity on the function of rice paddy field dams. By simulating and analyzing various rainfall scenarios, the researchers found that the peak ponding depth and the difference compared to paddy fields without runoff control plates could be larger when using stochastic methods to simulate rainfall patterns.

Summary: This study monitored stormwater runoff entering a rain garden facility, and found that the rain garden effectively reduced pollutants including solids, organics, nutrients, and heavy metals over a five-year period, with high volume reduction. However, volume reduction may decrease over time due to accumulation of solids, reducing infiltration capacity. In addition, a deep learning-based model was developed to predict pollutant concentrations with high accuracy.

Summary: This study found that rain gardens with internal water storage design showed significantly higher nitrogen removal efficiency and lower N2O emission potential compared to conventional rapid-filtration rain gardens. In terms of microbial composition, there were significant differences at the genus level between the two types of rain gardens, especially in potential denitrifying genera.

Summary: This paper introduces the HLM-Tetis model structure and its improvements over the previous HLM model structure. By adding modules to simulate snow processes, improving flexibility in simulating infiltration and percolation, and enhancing flexibility in deriving total runoff, the model has been applied to flood events in five basins in Iowa where previous model structures had limitations.

Summary: In the context of global climate change and the influence of human activities, the concept of sponge city is proposed to achieve the purification, collection, and reuse of rainwater. The effective evaluation of low impact development (LID) facilities in sponge cities is of great guiding significance for the promotion and construction of sponge cities.

Summary: This study examined the impacts of hydrological surface condition changes and climate change on flood runoff in a 45,421-km(2) watershed in the Loess Plateau region. Statistical methods were used to analyze the relationship between climatic variables, NDVI, LUCC data, and observed flood runoff. A rainfall-runoff model was used to quantify hydrologic responses to climatic variability and land-use change. The results showed that climatic variables did not significantly change over the study period. However, due to LUCC and climate change, peak discharges and flood volumes decreased in the study area.

Summary: The partition of surface runoff and infiltration is important in hydrologic modeling. Four strategies were designed to explore the influences of the runoff partition method on the flexible hybrid runoff generation model for improving flood prediction. The performances of the four strategies were compared and analyzed based on flow discharge and flood events in the Xun River watershed in Shaanxi Province, China. The improved two-source runoff partition method considering heterogeneity showed the best performance.

Summary: With the increasing threat of climate change, understanding the relationship between federal flood mitigation policies and local flood resilience is crucial. This study examines the impact of federal flood mitigation grants on the level of participation in FEMA's Community Rating System (CRS). The findings suggest that these grants do not significantly affect the level of CRS participation, and the factors influencing participation are mixed. The study also highlights the influence of previous participation levels on current participation, unrelated to federal grants.

Summary: The study examines the relationship between farming methods and spider web density in tea farms, with aerial photography captured by UAV and visual analysis. The results show that organic farming methods have the highest density of spider webs, followed by conventional farming methods, and the lowest density in sections using conventional farming methods. Aerial photographs and orthomosaic images allow for easy estimation and differentiation of organic tea farms from conventional farms.

Summary: Investigating the three-dimensional structure of mangrove forests is critical for their conservation and restoration. This study aimed to find a suitable LiDAR platform for accurately measuring the 3D structure of mangrove forests. Data from terrestrial LiDAR scanning TLS and unmanned aerial vehicle (UAV) LiDAR scanning ULS were used to create digital terrain models (DTMs). Results showed that ULS could not reproduce certain features of the forest, and TLS had a higher accuracy in tree segmentation. Combining TLS and ULS measurements improved tree canopy identification.
