Summary: This study proposes a simple approach to modify rainfall models to accurately capture sub-hourly rainfall characteristics, enabling the generation of sub-hourly rainfall data without the need for sub-hourly information. The new model outperforms traditional models at sub-hourly time scales, and successfully reproduces flooded areas in an urban watershed model using synthetic and observed rainfall data.

Summary: Short-duration extreme rainfall events are the main cause of flash and pluvial floods in cities. This study examined the impact of urbanization on sub-daily extreme rainfall intensities in Phoenix, Arizona. The results showed that the intensification trend of extreme rainfall intensities was significantly larger in the urbanized area compared to rural areas. The study also found that urbanization influenced air temperature but not humidity. These findings are important for urban planning and climate change research.

Summary: This paper aims to establish disaggregation coefficients for rainfall in Minas Gerais, Brazil, and verify their spatial variability. The results show that most disaggregation coefficients do not vary with return period, but differ significantly between locations and durations.

Summary: The temporal variability of rainfall in the rangelands of northern Australia is extremely high, occurring at different timescales. This study aims to estimate the 15-minute rainfall intensity (I15) using a well-established disaggregation scheme and the Bartlett-Lewis rectangular pulse (BLRP) model. The Fraser, RBL-E, and RBL-G models were assessed and showed underestimation of the observed I15, with RBL-E and RBL-G having a more serious underestimation.

Summary: In this study, a temporal disaggregation method for rainfall data was developed based on a stochastic rainfall model. The results suggest that extreme rainfall events may increase, thus calling for urgent measures to be taken.

Summary: The study analyzes extreme rainfall samples from Lazio and Sicily in Italy, finding that heavy-tailed distributions better describe the actual data compared to light-tailed ones. This can help improve the previous underestimation of extreme events.

Summary: This study proposes a strategy to evaluate the suitability of different multiplicative random cascades in producing rainfall time series considering climate change for green infrastructure models. The improved models, incorporating temperature dependency and reproducing rainfall temporal structure, were found to be applicable in multiple locations across Norway and France. Although the different models led to slight changes in the performance of green roofs, the impact was not significant compared to the uncertainties in climate modeling and stochastic nature of the process. The hydrological dampening effect of green infrastructure decreased in most Norwegian cities due to increased precipitation, while slightly increasing in Marseille due to a decrease in rainfall event frequency.

Summary: The study demonstrates that under climate change, hourly precipitation extremes and storm depths are expected to intensify in the US, with what is now a 20-year rainfall becoming a 7-year rainfall on average for approximately 75% of gridpoints. This intensification is mainly characterized by an increase in rainfall tail heaviness, with statistically significant changes in the seasonality and duration of rainfall extremes observed over about 95% of the domain.

Summary: A multisite fragments-based rainfall disaggregation procedure conditioned on circulation pattern classification was developed and applied to the German part of the Rhine river basin. The performance of the CP-based disaggregation in representing key rainfall characteristics was evaluated and the influence of different number of CP classes was investigated. The developed procedure opens up the possibility to consider dynamic changes in the atmosphere associated with climate change.

Summary: The study found that considering weather variables and sub-daily characteristics can improve disaggregation results, especially in estimating extreme events. These approaches seem to be much better than the basic disaggregation model.

Summary: This study aimed to analyze the ability of synthetic rainfall generation to improve SuDS design parameters by examining the main characteristics of observed rainfall and estimating hydrologic parameters. The results showed that the proposed methodology enhances the estimation of key characteristics of rainfall events and hydrologic parameters for SuDS design compared to values directly deduced from observed rainfall series.

Summary: Design flood estimation methods are crucial for ensuring the safety of hydrological and related infrastructure and informing water resources management. In South Africa, the availability of sub-daily rainfall data is limited, making it necessary to use rainfall temporal disaggregation techniques to produce finer resolution data. This study reviewed and assessed different temporal disaggregation methods and found that the SCS-SA and Knoesen models performed well in producing realistic temporal distributions.

Summary: This research aims to determine the potential changes in IDF curves due to climate change using climate model data. The equidistance quantile matching method is a highly successful method for obtaining shorter-term precipitation data. It is important to select the correct global climate model for modeling local climate.

Summary: In this study, a hydrological model is driven by observation-based hourly data and high-resolution climate model data to simulate river flows. The results show that the use of observation-based hourly data improves the accuracy of high flows and peak flow bias, but has little effect on low flows. The future changes in peak flows are slightly larger when driven by hourly climate model precipitation compared to equally-disaggregated daily data.

Summary: The increase in cement production due to growing demand in the construction sector leads to increased energy consumption and CO2 emissions. Researchers explored alternatives to silica fume in the production of UHPC, finding rice husk ash to be a successful substitute. Additionally, fly ashes, ground granulated blast furnace slag, and metakaolin can be used in conjunction with silica fume as partial substitutes.
