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...

Sensitivity Analysis of Hydraulic Parameters in the Simulation of Unsaturated Soil Water Dynamics

Soil water content is one of the most important parameters for estimating irrigation frequency and providing the plant’s water requirement. Since measurement of soil water content is both expensive and time consuming, water movement models are used to estimate these values. In this study, LEACHW model was used to estimate soil water content for two “dry” (20-29 Aug) and “wet” (1-6 Jul) periods ...

VARIATION IN SOil WATER AND SOil AIR CONTENTS ASSOCIATED WITH A VEGETATION - SOil SEQUENCE IN

SU.M~IARY: This paper describes part of a study of vegetation/soil system dynamics in which d~e re]ationships were demonstrated bctween structuraJ chang<' of the forest, with"associated changes in composition, and changes in otganic matter and soil physical properties, particularly the quantities cf water and air in non-capillarypores. Becausc of these rcsults an a.nalysis,\','as made of the qu...
