24 The present study deals with turbulent flows in an asymmetrical compound channel with an 25 embankment set on the floodplain, perpendicularly to the longitudinal direction. The main purpose of 26 this study was to assess how a rapidly varied flow affects interaction between the floodplain flow and 27 the main channel flow. In addition to rapid changes in the water level and velocity across t...

− In this study we describe a new concept for a sensor using fully distributed sensing along optical fibres designed especially for monitoring lateral movements in embankments and settlement areas, and deformations of excavation walls and tunnels. The sensor design includes four components: mass block housing, middle cylinder, connector housing, optical fibers and mass-block. The block housing ...

Stepped spillwayflows are characterised by significant free-surface aeration downstream of the inception point of air entrainment. The stepped design is advantageous for applications which require large energy dissipation and strong flow aeration. While the energy dissipation rate for embankment stepped spillways was studied previously, the optimum design for aeration and air–water mass transfe...

In this paper we investigate the process of embankment wave overtopping combinedwith overflow due to extreme surge levels that are above the embankment crest. AReynolds Averaged Navier-Stokes (RANS-VOF) model is employed to simulate thehydrodynamics. To investigate the success of the model at reproducing thehydrodynamic processes, the model is compared with experimental laborato...

Every year, Bangladesh experiences major floods that inundate about one-third of the country. Therefore, flood control projects that comprise earthen dikes and irrigation/drainage systems are built along the major rivers to protect the people living in low-lying areas, stabilize the river banks and improve agricultural productivity. However, the adverse effects of these projects are regularly e...

The Xing’anling Mountains are the second largest permafrost region in China. One of important issues for highways these regions is how to control settlement during operation period meet demand road stability. This paper selects a typical embankment Daxing’anling region, presents finite element models embankment, and verifies it using field monitoring data study thermal deformation characteristi...

this research intends to develop a method based on the artificial neural network (ann) to predict permanent earthquake-induced deformation of the earth dams and embankments. for this purpose, data sets of observations from 152 published case histories on the performance of the earth dams and embankments, during the past earthquakes, was used. in order to predict earthquake-induced deformation o...

The development of reinforcements for soil has made an impact in most the civil engineering sectors especially transportation. use geogrids is frequent roadways but they are also finding railways. major that could have providing desired stiffness to a section by reducing material and serving as proper reinforcement material. In current study, attempt been redesign railway embankment economicall...
