A Seepage-Deformation Coupled Analysis of an Unsaturated River Embankment using a Multiphase Elasto-Viscoplastic Theory

A Soil-Water Coupled Analysis of the Deformation of an Unsaturated River Embankment due to Seepage Flow and Overflow

In recent years, many disasters due to floods have occurred around the world. In some cases, the level of river water exceeded the estimated high-water level. It is necessary, therefore, to reconsider the evaluation method for river dike embankments during floods for the safety of the embankments. In this study, a deformation analysis is proposed that can simultaneously consider the unsaturated...

Groundwater recharge simulation using a coupled saturated-unsaturated flow model

Abstract The coupled MODFLOW-HYDRUS software package was used to produce a saturated-unsaturated flow model for a Flood Spreading System (FSS) and its associated aquifer. The study aim to improve simulations of near-surface hydrological processes, including temporal and spatial variation in groundwater recharge rates. The coupled model was built with average RMSE=1.1 and 1.3 for calibration ...

applying transitivity theory to gender analysis of efl textbook: : a comparative study.

efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...

An Elasto-viscoplastic Contact Problem: an a Posteriori Error Analysis and Computational Experiments

In this paper, we reconsider a contact problem between an elasto-viscoplastic body and a deformable obstacle. The contact is modeled by the classical normal compliance contact condition. Then, fully discrete approximations are obtained by using the finite element method to approximate the spatial variable and the forward Euler scheme to discretize time derivatives. An a posteriori error analysi...
