Two-dimensional nonlinear dynamic analyses (NDAs) are performed for a series of hypothetical embankment dams on spatially variable liquefiable foundation layer to evaluate the utility representing with random fields conditioned different levels site characterization information. A set two-dimensional parent models (PMs), each true condition, were generated using unconditional equivalent clean s...

Abstract The study explores the factors affecting sedimentation trends in surrounding catchment area of Tarbela Dam for period 1980–2017, specifically rain and temperature. Furthermore, this also investigates seasonal effects sediment loads coming into reservoir from 2007 to 2012. statistical techniques were applied estimation climate (rainfall temperature) on inflow its area. results revealed ...

For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....

Earthen dams and levees are prone to progressive failure through internal erosion of their structure. Internal erosion is often invisible to current methods of inspection until it manifests itself at the exterior surface. This study focuses on the novel use of passive seismic interferometry to monitor temporal changes in earthen embankments caused by internal erosion. This technique uses the am...

This paper uses a wealth shock from the construction of a flood protection embankment in rural Bangladesh coupled with data on the universe of all 52,000 marriage decisions between 1982 and 1996 to examine changes in marital prospects for households protected by the embankment relative to unprotected households living on the other side of the river. We use difference-in-difference specification...

The Grand Ethiopian Renaissance Dam (GERD), formerly known as the Millennium Dam, is currently under construction and has been filling at a fast rate without sufficient analysis on possible impacts body of structure. GERD not only an impact Blue Nile Basin hydrology, water storage flow but also poses massive risks in case collapse. Rosaries located Sudan 116 km downstream GERD, along with 20 mi...

The relativistic time dilatation effect and Einstein's second postulate of special relativity are used to analyse train/embankment thought expriments, both Einstein's original one, and an extension where observers on two trains moving at different speeds, as well as on the embankment, are considered. Whereas the relativistic analysis of Einstein's experiment shows, in contradiction to Einstein'...

Worldwide 83% of large dams are embankment structures (ICOLD, 1984), and the proportion is even greater for small dams. Embankment overtopping and breach is an important issue, and the Discusser congratulates the Author for his worthwhile contribution which complements the comprehensive study of Coleman et al. (2002). This discussion is focused on the breach development stage. It is shown that ...

Horizontal deformations can cause damage to objects adjacent to a newly constructed embankment. A tool has been developed to determine in an early state of a project if such a risk exists. The basis of this tool is an Artificial Neural Network (ANN). ANNs are particularly suited to find a relationship between an input and an output parameter, even if it is a very complex one. With this in mind,...
