Impact of ENSO, Global Warming, and Land Surface Elevation on Extreme Precipitation in India
(ASCE, 1/1/2020 1)The linkages of precipitation extremes with large-scale global climatic phenomenon such as global warming, the El Niño–Southern Oscillation (ENSO), and the land surface elevation were explored across India. Temporally, the ... -
Identifying Regional Models for Flow Duration Curves with Evolutionary Polynomial Regression: Application for Intermittent Streams
(ASCE, 1/1/2020 1)Regional models of flow duration curves (FDC) are ubiquitous components in water resources studies, particularly in ungauged sites or in catchments with scarce monitoring. The identification of such models in arid regions, ... -
Combining Postprocessed Ensemble Weather Forecasts and Multiple Hydrological Models for Ensemble Streamflow Predictions
(ASCE, 1/1/2020 1)Ensemble streamflow prediction (ESP), which is generally achieved by combining ensemble weather forecast (EWF) and hydrological model, has a wide application. However, the EWF is biased and underdispersive, and therefore ... -
Anthropogenic Impacts on Streamflow-Compensated Climate Change Effect in the Hanjiang River Basin, China
(ASCE, 1/1/2020 1)The relative importance of climate change and anthropogenic impacts on hydrology in the Hanjiang River Basin in China have become a hot topic because it has been manipulated by multiple activities, including reservoir ... -
Mean Velocity and Entropy in Wide Channel Flows
(ASCE, 1/1/2020 1)For decades many authors have used entropy-based models to predict velocity distribution in open channel flows. Such models use maximum and mean velocity in an assigned domain to obtain velocity distribution. However, while ... -
Projection of Reference Crop Evapotranspiration under Future Climate Change in Poyang Lake Watershed, China
(ASCE, 1/1/2021)Reference crop evapotranspiration (ET0) is of great importance in assessing the potential impacts of climate changes on hydrological cycles and the global energy balance. The spatiotemporal change of ET0 and the drought ... -
Development of Synthetic Rating Curves: Case Study in Iowa
(ASCE, 1/1/2021)This case study describes an economically feasible approach to generate synthetic rating curves that enhance utility of stage-only river gauges. The study is based on a network of 250 bridge-mounted river-stage sensors ... -
Variable-Sized Cluster Analysis for 3D Pattern Characterization of Trends in Precipitation and Change-Point Detection
(ASCE, 1/1/2021)A novel analysis procedure, referred to as variable-sized cluster analysis (VSCA), was developed to identify trends and change points in precipitation time series data set. The procedure involved station-scale rainfall ... -
Identification of Combined Hydrological Models and Numerical Weather Predictions for Enhanced Flood Forecasting in a Semiurban Watershed
(ASCE, 1/1/2021)Flood forecasting in urban and semiurban catchments is often limited by the capability of the combined hydrological models and forecast inputs to predict floods accurately. The objective of this research is to develop an ... -
Calibration of Concentration Parameters Based on Frequency Decomposition of Fourier Series
(ASCE, 1/1/2021)The unstable and unreasonable parameter identification results are achieved because of the nonlinear effect (e.g., the cross-autocorrelation parameters). The XAJ (Xin’anjiang) model shows a certain correlation among ... -
Comprehensive Drought Assessment Tool for Coastal Areas, Bays, and Estuaries: Development of a Coastal Drought Index
(ASCE, 1/1/2021)The interface of freshwater and saltwater plays an important role in the economic and social dynamics along the coast and estuaries. Droughts in coastal areas have ecological impacts and affect socioeconomic dynamics and ... -
Improving the Accuracy of Snow and Hydrological Models Using Assimilation by Snow Depth
(ASCE, 1/1/2021)The main aim of this study is to improve the underestimation of spatial snowfall distributions by using assimilation. Although measuring snowfall depth is crucial to evaluate snow water resources and predict snowmelt runoff ... -
Modeling Storm Sewer Networks and Urban Flooding in Roanoke, Virginia, with SWMM and GSSHA
(ASCE, 1/1/2021)Modeling urban flooding is challenging because of complex spatial variations and interactions between precipitation, land cover, and drainage networks. This paper presents a case study of the development of two hydrology ... -
Analytical Model for Volatile Organic Compound Transport in the Coupled Vadose Zone–Groundwater System
(ASCE, 1/1/2021)A 3D mathematical model that describes transport of volatile organic compounds in a coupled vadose-saturated zone system is proposed. The subsurface processes incorporated in the model include advection, dispersion, ... -
Alterations in the Water-Level Regime of Tonle Sap Lake
(ASCE, 1/1/2021)The Tonle Sap Lake (TSL), located in southwestern Mekong Basin, is the largest freshwater lake in Southeast Asia. The water-level regime of the TSL has been changing over the last few decades due to the rapid development ... -
Cultivating Stormwater Services with Soil Decompaction and Amendment
(ASCE, 1/1/2021)Stormwater management has traditionally focused on increased runoff from impervious areas (IAs) accompanying urbanization. Far less consideration has been directed to significant changes in the hydrologic characteristics ... -
Investigating the Role of Hydrological Model Parameter Uncertainties in Future Streamflow Projections
