The construction of a reservoir on large-thickness collapsible loess cover will significantly increase the occurrence dam break disasters. main reason may be that although gradation particle is not uniform. clay content less than 10%. Piping channels easily form under action force and collapsibility. Near-static liquefaction in body saturated condition lead to piping or loss soil strength. Ther...

Investigations of breeding ecology of interior least tern (Sternula antillarum athalassos) and piping plover (Charadrius melodus) in the Platte River basin in Nebraska, USA, have embraced the idea that these species are physiologically adapted to begin nesting concurrent with the cessation of spring floods. Low use and productivity on contemporary Platte River sandbars have been attributed to a...

choice for pharmaceutical industry process systems. Its high mechanical strength and low coefficient of thermal expansion allow components to be sterilised or sanitised using various mediums and at high temperatures. Concerns about stainless steel systems – such as rouging in high purity water, metallic ion contamination and inner surface finishes – which require post-installation maintenance a...

This paper is an extension of previous work which characterises soil behaviours using the grading entropy diagram. The present work looks at the piping process in granular soils, by considering some new data from flood-protection dikes. The piping process is divided into three parts here: particle movement at the micro scale to segregate free water; sand boil development (which is the initiatio...

In the first part of the report, we review various efforts that have been recently performed in the USA in the field of reactor health monitoring. They were carried out by different organizations and they addressed different issues related to the safety of nuclear reactors. Among other aspects, we present technical issues related to the design of a self-diagnostic monitoring system for the next...

Natural pipes are common in many upland blanket peats, yet little is known about pipe network morphology or pipeflow processes. Most information on soil piping comes from the shallow peaty podzols of the Welsh uplands, where monitoring suggests that pipes may be important contributors to streamflow. This paper presents information on piping and pipeflow from a deep upland blanket peat catchment...
