Abstract: Three geographic information system (GIS)-based distributed hydrological models were developed for flood simulation and forecasting in a subbasin of the Yellow River. A grid-and-topography-based distributed hydrological ...

Abstract: This paper proposes a microscopic spatial-temporal method to capture the vehicle movement trajectories at an isolated intersection. A bi-objective programming model is presented to minimize the overall delay and emission ...

Abstract: A distributed rainfall-runoff model, Grid-Xinanjiang model based on the topographical information of each grid cell extracted from the digital elevation model (DEM), was developed to simulate the hydrologic processes within ...

Abstract: A prompt availability of precipitation intensity is crucial for accurate and effective flood forecast. When radars are coordinated, the mosaic of weather radar can perform rainfall estimation over large areas. This study ...

Abstract: When applying a back-propagation neural network (BPNN) model in hydrological simulation, researchers generally face three problems. The first one is that real-time correction mode must be adopted when forecasting basin ...

Abstract: A novel chlorine- and fluorine-free liquid accelerator was developed in this study. The proportion of each component of the accelerator was determined using an orthogonal test method. Various additives’ impact on the cement ...
