Evaluation of Stormwater Infrastructure Design Storms Developed Using Partial Duration and Annual Maximum Series Models
(American Society of Civil Engineers, 2018)This study assesses the advantages and limitations of developing design storms using the partial duration series exceedance-based (PDS-E) rainfall frequency model in comparison with the annual maximum series (AMS) model. ... -
Reliability-Based Water Quality Assessment with Load Resistance Factor Design: Application to TMDL
(American Society of Civil Engineers, 2018)Effective load reduction strategies rely on an accurate Total Maximum Daily Load (TMDL) calculation, which assesses pollutant loading from various sources. Quantification of uncertainty is a critical part of the TMDL ... -
Comparison of Two Alternative Methods for Developing TMDLs to Address Sediment Impairments
(American Society of Civil Engineers, 2018)While excessive sediment is a leading cause of aquatic life use impairments in free-flowing rivers in Virginia, there is no numeric sediment-water quality criterion. As a result, total maximum daily load (TMDL) sediment ... -
Assessment of Streamflow Change in Middle-Lower Reaches of the Hanjiang River
(American Society of Civil Engineers, 2018)The hydrological processes of the middle-lower reaches of the Hanjiang River have been altered significantly because of water diversion and reservoir construction. The combined wavelet transformed Mann-Kendall (WT-MK) trend ... -
Entropy-Based Approach of Hydraulic Geometry of Navigable Canals
(American Society of Civil Engineers, 2018)In navigable canals, ship hydrodynamics compared to water flow have been the most dominant dynamic factors that influence the evolution of cross-sectional morphology, so that the existing hydraulic geometry relations used ... -
Saltwater Intrusion and Recirculation of Seawater in Isotropic and Anisotropic Coastal Aquifers
(American Society of Civil Engineers, 2018)Saltwater intrusion and the recirculation of seawater that occur at the seacoast in coastal aquifers are investigated for vertically isotropic and anisotropic aquifers as dependent functions of two independent dimensionless ... -
Effect of Return Period on Normalized Rainfall Distributions in the United States
(American Society of Civil Engineers, 2018)The assumption that normalized 24-h rainfall distributions are independent of return period is investigated. The results of this study show that this assumption is justified in the interior region of the eastern United ... -
Spatiotemporal Complexity Analysis of Daily Precipitation in a Changing Environment in Heilongjiang Province, China
(American Society of Civil Engineers, 2018)Complexity analysis is an important tool for research on water resources. Although physical methods and quantitative detection are typically used to explore system complexity, this study uses a method combining probabilistic ... -
Hydrologic Downscaling of Soil Moisture Using Global Data Sets without Site-Specific Calibration
(American Society of Civil Engineers, 2018)Numerous applications require fine-resolution (1–3 m) soil moisture patterns, but most satellite remote sensing and land-surface models provide coarse-resolution (9–6 km) soil moisture estimates. The Equilibrium ... -
Modeling Nonstationary Extreme Water Levels Considering Local Covariates in Ho Chi Minh City, Vietnam
(American Society of Civil Engineers, 2018)Recently, human intervention and climate change have been proposed as the causes of changes in extreme water levels, which impact the likelihood of flooding, especially in coastal areas. In many studies, frequency analysis ... -
Using the SWAT Model in Intensively Managed Irrigated Watersheds: Model Modification and Application
(American Society of Civil Engineers, 2018)The Soil and Water Assessment Tool (SWAT) is a well-established modeling tool for simulating hydrologic processes in watershed systems. However, SWAT often does not perform well in highly managed watersheds with intensive ... -
Stochastic Generation of Streamflow Time Series
(American Society of Civil Engineers, 2018)This paper proposes, systematizes, and validates a methodology for stochastically generating streamflow time series at virtually any time scale. Starting from deseasonalized data (i.e., observed series removed of their ... -
Reservoir Inflow Forecast Using a Clustered Random Deep Fusion Approach in the Three Gorges Reservoir, China
(American Society of Civil Engineers, 2018)Reservoir inflow forecast plays a crucial part in programming, development, operation, and management of water resource systems. To better reveal the complex properties of daily reservoir inflow, a clustered deep fusion ... -
Dimensionally Consistent Nonlinear Muskingum Equation
(American Society of Civil Engineers, 2018)Although the Muskingum equation was proposed nearly 75 years ago, it is still a subject of active research. Despite of its simple form, the real properties of this equation have not been comprehensively explained. ... -
Assessment of Chen and Other Methods for Estimating Intensity-Duration-Frequency Functions
(American Society of Civil Engineers, 2018)Estimation of intensity-duration-frequency (IDF) functions at ungauged locations is sometimes done using the method introduced by Chen in 1983 [Chen, C. 1983. “Rainfall intensity-duration-frequency formulas.” J. Hydraul. ... -
Suspended Sediment Concentration and Discharge in Open Channels Using Rényi Entropy
(American Society of Civil Engineers, 2018)The vertical distribution of suspended sediment concentration in an open channel is modeled using Rényi entropy. The model, derived by invoking the principle of maximum entropy, is tested against field and laboratory ... -
