Assessing River Embankment Stability Under Transient Seepage Conditions

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...

An Immission Based Evaluation of the Efficiency of the Sewer-wwtp-river System under Transient Conditions

Assessing River Low-Flow Uncertainties Related to Hydrological Model Calibration and Structure under Climate Change Conditions

Low-flow is the flow of water in a river during prolonged dry weather. This paper investigated the uncertainty originating from hydrological model calibration and structure in low-flow simulations under climate change conditions. Two hydrological models of contrasting complexity, GR4J and SWAT, were applied to four sub-watersheds of the Yamaska River, Canada. The two models were calibrated usin...

Fluxes of PAHs from coal tar-impacted river sediment under variable seepage rates.

The flux of several polycyclic aromatic hydrocarbons (PAHs) from coal tar-impacted river sediment was measured under various seepage rates in a laboratory scale. The batch PAH equilibrium data between aqueous phase (C(eq)) and sediment phase was well-explained using a Raoult's law approach. In the flux measurement from column study, the steady-state PAH concentrations (C(infinity)) in the efflu...

Assessing Reading Comprehension Strategies under Three Learning Conditions

The purpose of this study was to measure reading comprehension strategies when Tell Me More and Sweet English software were utilized to enhance the traditional reading comprehension practice. The study focused on evaluation of four strategies (i.e., scanning, skimming, inferencing and headline guessing) in reading comprehension in three different classes at an English language Institute in Iran...
