Large-Scale Flood-Inundation Modeling in the Mekong River Basin
(American Society of Civil Engineers, 2018)Flood impacts threaten the socioeconomic conditions of peoples’ lives in the Mekong River Basin. In this study, the rainfall-runoff-inundation (RRI) model, capable of simulating rainfall runoff and flood inundation ... -
Characterizing the Evolution of Groundwater Flow Field and Its Driving Forces in Xi’an, China
(American Society of Civil Engineers, 2018)This paper studied the temporal and spatial variation of groundwater levels that characterized the evolution of the groundwater flow field in Xi’an, China, from 1965 to 213, by using the wavelet analysis method. Then under ... -
Space-Time Cokriging Approach for Groundwater-Level Prediction with Multiattribute Multiresolution Satellite Data
(American Society of Civil Engineers, 2018)The availability of complete, continuous, and reliable groundwater data is essential for preparing a regional-scale groundwater model. Poor sampling of groundwater level is often encountered. Satellite-derived data can ... -
Magnitude-Frequency Analysis for Suspended Sediment Transport in the Ganga River
(American Society of Civil Engineers, 2018)Sediment load in the Ganga river is among the highest in the world. Effective discharge for suspended sediment transport at 15 stations on the Ganga river has been computed using a mean and rating curve approach in the ... -
Double Constraint Method for Pumping Test Analysis
(American Society of Civil Engineers, 2018)A double constraint method is proposed to analyze pumping tests in a confined aquifer. An expression for estimation of aquifer transmissivity is derived by minimizing the sum of squared errors in the Darcy equation and a ... -
Modeling Simulation of River Discharge of Loktak Lake Catchment in Northeast India
(American Society of Civil Engineers, 2018)Water resources management requires an integrated approach between sustainability and catchment management to provide an enhanced understanding of usage options and environmental impacts. Discharge contributes significantly ... -
Increasing Stage Variability of the Mississippi River
(American Society of Civil Engineers, 2018)The likelihood of catastrophic floods in the Mississippi River correlates with a direct measure of variability, the magnitude of the day-to-day variations in river stage. At several sites along the Middle Mississippi River, ... -
Effect of Herbicides on Evapotranspiration of Willow Marshes in the Upper St. Johns River Basin, Florida
(American Society of Civil Engineers, 2018)During the last 4 years, Carolina willow (Salix caroliniana Michx.) expanded into areas previously dominated by herbaceous marshes in the Upper St. Johns River basin (USJRB) of east-central Florida, United States. ... -
Suitability of a Linear Model for Predicting Cohesive Soil Detachment during Jet Erosion Tests
(American Society of Civil Engineers, 2018)Cohesive soil detachment is a complex process that is typically simulated using simplified mathematical models such as the linear excess shear stress equation or power laws. The assumption of linearity between applied shear ... -
