AbstractInflow forecasts are a basic pre-requisite to support decisions for anticipating reservoir operations. The fact that hydrological forecasts are uncertain, noting that reservoirs often fulfill multiple purposes, bears the risk of non-ideal reservoir operation. Optimization techniques can help to identify the best operational scheme under given inflow. To address the forecast uncertainty, operators can repeat optimization (moving horizon approach) and optimize for inflow forecast ensembles. This article aims to contribute to a better understanding of how the different methods work, how to interpret the results and what the effect of user choices on the optimization results is. The moving-horizon approach and three ensemble optimization methods were applied on a hydropower reservoir in Norway under flood conditions. The functional principle of each method is explained, and advantages and drawbacks of the different methods are discussed with the help of performance indicators.Keywords: Reservoir optimizationflood forecastingensemble forecastRTC-Toolsmodel predictive controlstochastic optimization Disclosure statementNo potential conflict of interest was reported by the author(s).

ABSTRACTMud filled by upstream surface runoff is one of the problems in maintaining the reservoir and dam. The material of upstream bed has a significant effect on the filling of reservoirs. In the present work, the filling rate of the reservoir from the upstream movable bed is investigated by using the Herschel–Bulkley model in both shear-thickening and shear-thinning modes. For this, a two-phase Newtonian-non Newtonian SPH code was developed that has special capabilities such as turbulence effects, surface tension, free surface, and particle displacement. This computational code is then evaluated by the experimental results in addition to finally used to investigate the main problem mentioned above. Five different models of movable beds with are considered, and the filling rate of the downstream tank with these materials is discussed. The results show that among the parameters of the Herschel–Bulkley model, the yield stress is more effective than other factors. Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe datasets generated during and analysed during the current study are available from the corresponding author on reasonable request.

AbstractThis study investigates the performance of green roofs with three different types of substrate, which are topsoil, a mix of 60% topsoil and 40% biochar, and a mix of 60% topsoil and 40% cocopeat in terms of saturated bulk density and water retention efficiency with a roof slope of 16.7°. The substrate has a thickness of 35 mm and was supported by a timber green roof prototype with Zoysia Japonica, Local cow grass and 9 o’clock flower as vegetation. It was also observed from the experiment that with respect to vegetation, the water retention efficiency is 50.3% (Zoysia Japonica), 49.3% (Local cow grass), and 57.4% (9 o’clock flower) with topsoil and cocopeat for a rainfall of 10 mm for a period of 20 min. Based on this research, a 9 o’clock flower with substrate combining topsoil and coco peat is recommended for green roofs in tropical climates. Disclosure statementNo potential conflict of interest was reported by the authors.
