Summary: This study assessed the suitability of a previously developed model for determining the runoff coefficient in green roofs (GRs) and evaluated different time scales for runoff coefficient determination. The results showed that the model did not fit the experimental data from this study, indicating the need for a new model that considers additional variables. The study also found that monthly determination of the runoff coefficient resulted in lower values than weekly or per rain event determination, but there were no significant differences when applied to long-term performance analysis.

Summary: Green roof systems (GRs) are a promising solution for managing stormwater in urban areas with limited open space. This paper reviews three popular types of GR models and discusses their developments, applications, and limitations. The models can simulate GR outflow and have varying complexities and parameter requirements. SWMM is widely used for watershed-scale simulations of GR implementations. However, there is a need for long-term monitoring and modeling of full-scale GR systems to fully understand their effects on stormwater management.

Summary: This study evaluated the technical feasibility of a multilayer detention roof, called a purple roof, in managing urban stormwater. The purple roof outperformed other roof systems by delaying the start times of runoff, reducing runoff volume, and taking longer to discharge stormwater. The study demonstrates that the purple roof technology is effective in slowing the release and reducing the volume of stormwater during different-sized rainfall events.

Summary: The global popularity of green roofs is increasing due to urban runoff being a major environmental concern. A statistical analysis of 2375 original experimental samples from 21 countries shows that factors such as rainfall intensity, substrate depth, and vegetation type impact the retention performance. There is a need for more research and application of green roofs in certain regions, and potential improvements in retention rates.

Summary: The study aimed to assess the characteristics of different-sized particles in the first flush of roof runoff. Runoff samples were collected from an asphalt roof, metal roof, and cement roof for analysis. The particle size distributions in the runoff from the three roofs showed no clear patterns and were influenced by several factors. The strength of the first flushes differed significantly for particles in different size categories in the runoff from the three types of roofs and were different from suspended solids.

Summary: This study evaluates the behavior of septic system derived nutrients in a sandy nearshore aquifer and their discharge to a large lake, revealing the complex behavior of NO3-N and PO4-P in groundwater plumes. The study finds that septic systems along the Canadian Lake Erie shoreline are only a minor contributor to the annual P and N loads to the lake, but they may contribute to localized algal blooms in shoreline areas with high septic system density. The findings highlight the potential impact of nutrient inputs from septic systems on changing the N:P ratio in nearshore waters and promoting growth of harmful cyanobacteria.

Summary: The paper introduces a quantitative method for predicting the relative composition of PFAS in different phases, aiming to reconcile composition differences in different phases from various sources. The results provide a baseline for recognizing cases where hydrophobicity is not the primary driver of PFAS distribution between phases, and may be useful in forensic applications for classifying PFAS across phases.

Summary: The study aimed to develop a method to simulate human weathering of silver-containing textiles. It found that non-weathered textiles released a certain amount of silver into wash water effluent, with a portion being ionic silver and the rest as metallic nanomaterials, nanosheets, and particulates. Real and simulated human weathered textiles released similar amounts of total silver, consisting of ionic and a mixture of metallic and chlorinated nanomaterials, nano-sheets, and particulates. The method effectively detached environmentally representative silver materials from textiles for future studies on their fate, transport, and toxicity.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.
