Abstract: A new type of estuary-management model based on discrete-time stochastic linear quadratic optimal control is presented. It is a feedback-control model that enables decision makers to determine the upstream reservoir releases ...

Abstract: Alluvial fans along mountain bases pose quite interesting problems for the design of hydraulic structures and highway crossings and for flood insurance studies. The Federal Emergency Management Agency (FEMA) alluvial-fan ...

Abstract: Piping-seepage damage is one of the major factors leading to tailings dam failure. To explore the microscopic influence mechanism of tailings with different fine content on piping development, on the basis of the indoor ...

Abstract: Least squares (LS) methods are frequently used to determine an optimal unit hydrograph (UH) for a watershed. However, the conventionally used ordinary LS method could potentially produce a UH with unwanted fluctuation among ...

Abstract: Manufactured with a multilayer functional composite fabric envelope, lighter-than-air (LTA) airships offer a cost-effective approach for payload platforms. Considering the long-term service of LTA airships and their severe ...

Abstract: Stress distribution on a membrane surface plays a key role in the structural safety and bearing capacity of an inflatable membrane structure, especially for the state under service condition. This paper presents an in situ ...

Abstract: Ignition and high altitude restarts under extreme conditions have always been key research problems due to low pressure and temperature of inlet air, so reliable ignition and wide ignition boundary is very necessary. In ...

Abstract: A stratospheric airship (SSA) is a cost-effective platform for telecommunications and science missions in near space 20 km above the Earth’s surface. However, an accurate model of the structural behavior of the large ...

Abstract: In hydraulic and hydrologic studies, engineers develop new models or calibrate existing models by various techniques. One is often concerned with the model validity regarding its ability to predict future events. Five ...
