Regional Calibration of the NRCS Unit Hydrograph Peak Rate Factor for New Jersey as a Result of Hurricane Irene
(American Society of Civil Engineers, 2019)Synthetic unit hydrographs are used to predict the response of a watershed to a precipitation event. They utilize the physical characteristics of a watershed for their development. Although a variety of synthetic unit ... -
Modeling for TMDL Implementation
(American Society of Civil Engineers, 2019)The Clean Water Act and USEPA’s total maximum daily load (TMDL) program established requirements to determine the amount of a pollutant that a waterbody can assimilate and still attain water-quality standards. A variety ... -
Automated Urban Rainfall–Runoff Model Generation with Detailed Land Cover and Flow Routing
(American Society of Civil Engineers, 2019)Constructing hydrological models for large urban areas is time consuming and laborious due to the requirements for high-resolution data and fine model detail. An open-source algorithm using adaptive subcatchments is proposed ... -
Infiltration Simulation with Improved Green-Ampt Model Coupled with the Wet Zone Partition Function
(American Society of Civil Engineers, 2019)The soil water content usually appears to be distributed in distinct layers during the process of homogeneous soil infiltration. However, existing infiltration models rarely consider the partitioning characteristics of the ... -
Rescaling Transposed Extreme Rainfall within a Heterogeneous Region
(American Society of Civil Engineers, 2019)Geospatial transposition of observed storms can be useful for examining potential rainfall and flood hazards, and several recent software packages help facilitate transposition of remote sensing–based rainfall observations ... -
Water Quality–Based Environmental Flow under Plausible Temperature and Pollution Scenarios
(American Society of Civil Engineers, 2019)This study aimed to estimate water quality–based minimum environmental flow (Eflow) of a river under the impact of different plausible scenarios. The water quality model QUAL2K was deployed to simulate levels of dissolved ... -
Relationship of Drought and Engineered Water Supply: Multivariate Index for Quantifying Sustained Water Stress in Anthropogenically Affected Subbasins
(American Society of Civil Engineers, 2019)Drought occurs across all climates worldwide, but has different impacts from one region to another. Because water is the most basic of human needs, drought and water shortage can result in severe socioeconomic difficulties ... -
Diagnostic Evaluation of Hydrologic Models Employing Flow Duration Curve
(American Society of Civil Engineers, 2019)The assessment of water availability using hydrological models is subject to modeling uncertainties. Model performance evaluation based on conventional likelihood measures on an overall time-series simulation has shortcomings. ... -
Hybrid Wavelet-M5 Model Tree for Rainfall-Runoff Modeling
(American Society of Civil Engineers, 2019)In this study, the hybrid wavelet-M5 model was introduced to model the rainfall-runoff process via three different data division strategies (75%–25%, 60%–40%, and 50%–50%) for two different catchments at both daily and ... -
Closure to “Influence of Daily Regulation of a Reservoir on Downstream Navigation” by Yizi Shang, Xiaofei Li, Xuerui Gao, Yanxiang Guo, Yuntao Ye, and Ling Shang

Bivariate Risk Analysis of Droughts Using a Nonparametric Multivariate Standardized Drought Index and Copulas
(American Society of Civil Engineers, 2019)The Nonparametric Multivariate Standardized Drought Index (NMSDI) based on precipitation and soil moisture data in conjunction with copula functions is of primary concern in this study. We are the first to investigate ... -
Comparing Watershed Scale P Losses from Manure Spreading in Temperate Climates across Mechanistic Soil P Models
(American Society of Civil Engineers, 2019)Watershed scale modeling is commonly used to evaluate nutrient fluxes to surface waterbodies and the appropriateness of regulatory intervention, such as the implementation of a total maximum daily load (TMDL). The Soil and ... -
Evaluating the Emergent Controls of Stream Water Quality with Similitude and Dimensionless Numbers
(American Society of Civil Engineers, 2019)The emergent hydrologic and land-use controls of coastal-urban stream water quality were evaluated by using similitude and dimensional analysis, considering southeast Florida a prototype of growing coastal-urban environments. ... -
Evaluating Metropolitan Flood Coping Capabilities under Heavy Storms
(American Society of Civil Engineers, 2019)A large city surrounded by mountains like Hong Kong is susceptible to both flash floods in midmountain areas and local flooding in low-lying areas when a large rainstorm occurs. Severe rainstorms tend to be more frequent ... -
Gravity-Driven Infiltration and Subsidence Phenomena in <i>Posidonia oceanica</i> Residues
(American Society of Civil Engineers, 2019)A simplified infiltration model for highly permeable porous media was introduced, assuming the matric potential gradient as negligible compared to the gravitational gradient. This model enabled us to determine the delay ... -
Bivariate Design of Hydrological Droughts and Their Alterations under a Changing Environment
(American Society of Civil Engineers, 2019)Few studies have focused on the multivariate joint design of drought properties. Using daily streamflow data, this paper analyzes the impacts of pooling and exclusion of drought events in determining hydrological drought ... -
