Summary: This study evaluated the effectiveness of detention ponds in mitigating the impacts of urban stormwater runoff on downstream waterbodies. The findings suggest the need to improve detention pond efficiency or identify alternative strategies for protecting waterbodies from the effects of urbanization.

Summary: Urban retention ponds are a common stormwater control measure in coastal areas, but can also be a source of pollutants. Research showed that the treatment efficiency of retention ponds improved during warmer months, likely due to increased biological activities. Modeling with SWMM can help assess performance beyond one-year monitoring studies, suggesting additional research to better understand biogeochemical processes within ponds.

Summary: Green stormwater infrastructure (GSI) is recognized as an effective means to reduce urban runoff impacts. This study quantifies the relationships between urban greenness, GSI, and hydrology. The results show that urban greenness has significant influences on downstream flow responses, and GSI implementation has a weak influence on urban greenness.

Summary: The hydrologic response of urban watersheds to pulse rainfall events can be explained by watershed properties, despite differences in storm events. Variation in SWM and impervious cover did not significantly affect hydrograph peak attenuation, with the primary difference observed on the recession limb. Findings suggest that SWM may be less effective at attenuating urban hydrographs than commonly assumed, and impervious cover may have a greater influence on runoff volume than SWM coverage.

Summary: Global warming has had a significant impact on hydrological processes in alpine cryosphere regions. This study collected long-term stable isotopic data on streamwater in a catchment in the central Tibetan Plateau to assess water age. The results showed that the mean streamwater age was 77 days and that 30% of the streamwater was less than 41 days old on average. The study found that streamwater age was younger in glacier and permafrost catchments and that it was influenced by glacier and permafrost coverage, precipitation, relative humidity, and changes in glaciers and permafrost.

Summary: Stormwater ponds improve water quality by facilitating sedimentation of contaminants, but periodic removal of accumulated sediments is necessary to maintain their capacity. Variability in contamination levels between ponds was observed, influenced by dilution of urban pollutants and other particle sources.

Summary: This study addresses novel approaches to measure and quantify de novo lipogenesis (DNL) in non-alcoholic fatty liver disease (NAFLD). Stable isotope tracers, such as deuterated water, can accurately measure DNL rates and provide detailed information on lipid biosynthesis through NMR and MS analysis. This is of great importance for understanding the mechanisms and potential interventions for NAFLD.

Summary: This study evaluated two methods for measuring the hydraulic conductivity of the sediment-water interface (SWI) in stormwater ponds. The results showed that sediment deposition and organic matter content significantly affected the hydraulic conductivity. Comparing two ponds with a 22-year age difference, pond age was found to be correlated with grain size and hydraulic conductivity. Monitoring changes in the SWI of stormwater ponds is important for flood protection, runoff control, and groundwater recharge.

Summary: This study explores the potential of remote sensing techniques to retrieve water level and key water quality parameters in urban stormwater wet ponds. The results show that RS techniques can accurately estimate water level, chlorophyll-a, turbidity, Secchi depth, and total suspended solids in these ponds. The study also uncovers the relationship between water temperature and chlorophyll-a concentration and identifies a correlation between sediment and chlorophyll-a spatial distribution.

Summary: Increased urbanization and climate change require further evaluation of the impact of urban development on water flow paths for sustainable land-use planning. The complex interaction of water fluxes within urban water stores and their effects on streamflow regimes over time need to be quantified. This study utilized hydrological and water stable isotope datasets to evaluate water flow paths and ages in a heavily urbanized catchment in Berlin. The results provide valuable information for assessing the uncertainty of urban impacts on hydrological function under environmental change.

Summary: In the framework of landslide study, it is crucial to understand the hydrogeological features and origins of groundwater for risk mitigation. This study aims to define the potential groundwater origin of a high-risk urban landslide in central Italy and develop a hydrogeological conceptual model. Multiple techniques including hydrological water balance, tracer tests, stable isotope analysis, hydro-chemical survey, and piezometric level fluctuation analysis were used. The study identified two groundwater bodies, with evidence of local water contributions from leakage of the urban sewerage system.

Summary: Urban landscapes significantly modify the pathways of rainfall and meltwater to streams, making it challenging to fit them into common conceptual models of streamflow generation. This study examined the relative contribution of different water sources to urban stormflow and found that old water accounted for a significant proportion of the storm hydrograph. The use of tracer data is important for further understanding the role of greenspaces and storm characteristics on water partitioning in urban catchments.

Summary: A 2-year field study on microplastic pathways in urban stormwater runoff and bioretention cells found that urban stormwater runoff is a concentrated source of microplastics whose concentrations are influenced by specific climate variables. Bioretention cells are effective in filtering out microplastics and preventing their spread downstream, highlighting the potential for current low impact development practices to limit microplastic contamination in larger aquatic systems.

Summary: Nature-based solutions or Green infrastructure (GI) are increasingly popular for managing stormwater pollution globally. The MUSIC model, an important tool for planning these systems, was evaluated for its performance in a tropical climate. The model was able to reasonably simulate outflows and pollutant concentrations, but had some limitations in simulating hydrographs and pollutographs under different inflow and drying/wetting conditions.
