Joint Probability Study of Destructive Factors Related to the “Triad” Phenomenon during Typhoon Events in the Coastal Regions: Taking Jiangsu Province as an Example
(ASCE, 11/1/2020 )Strong winds (W), storm tides (Z), and heavy rains (R) are the main destructive factors related to typhoons that affect the coastal regions of Jiangsu, where the “triad” phenomenon is obvious. Statistical results from 1960 ... -
Multicriteria Decision-Making Approach to Enhance Automated Anchor Pixel Selection Algorithm for Arid and Semi-Arid Regions
(ASCE, 11/1/2020 )Finding the precise value of pixel-scale evapotranspiration (ET) for an entire basin is a major challenge to hydrologists. Many efforts have been made to conquer this challenge, among which remote sensing methods are the ... -
Spatial Arrangement of Stormwater Infiltration Affects Subsurface Storage and Baseflow
(ASCE, 11/1/2020 )Urban stormwater management is turning towards use of infiltration facilities, directing water that would have previously flowed overland into subsurface flow paths. Stormwater infiltration alters soil moisture, groundwater, ... -
Assessment of Groundwater-Level Monitoring Network in Irrigated Regions with a Complex Aquifer System Using Information Theory
(ASCE, 11/1/2020 )The present study focuses on the assessment of groundwater level monitoring networks (GWLMN) by examining the statistical relationship between groundwater level (GWL) uncertainty and sustainable groundwater indicators ... -
Pressure Transient Analysis to Determine Anisotropic Fault Leakage Characteristics
(ASCE, 11/1/2020 )Deep saline aquifers have the large required capacity to dispose of or store fluids in the subsurface. The consequent overpressure may cause undesirable brine leakage through possible interlayer pathways. Faults can ... -
Entropy-Based Velocity and Shear Stress Distributions for Trapezoidal Channel
(ASCE, 11/1/2020 )A multitude of studies have derived one-dimensional velocity distributions, assuming open channels to be rectangular, and have extended their applications to rivers, canals, and other open channels. A cumulative distribution ... -
Evaluation of Trends and Dominant Modes in Maximum Flows in Turkey Using Discrete and Additive Wavelet Transforms
(ASCE, 11/1/2020 )This paper aims to define trends and dominant modes in annual instantaneous maximum flows (AIMF) covering the period 1961–2014 from 10 gauge stations located in different river basins in Turkey. To achieve this aim, ... -
Rainfall Intensity-Duration-Frequency Relations under Changing Climate for Selected Stations in the Tigray Region, Ethiopia
(ASCE, 11/1/2020 )Developing intensity, duration, and frequency (IDF) of rainfall with the reflection of future climate change is required for designing and managing water infrastructures. Hence, this study was aimed to predict future changes ... -
Study on Two-Dimensional Numerical Simulation of Rainstorm and Torrent in Small Watershed Based on Lidar Data
(ASCE, 9/1/2020 1)To analyze the process and mechanism of slope confluence of rainstorm and flood in small watersheds, a two-dimensional hydrodynamic model was built based on high-precision lidar data of point cloud and the field flood ... -
Seepage Face in Steady-State Groundwater Flow between Two Water Bodies
(ASCE, 9/1/2020 1)An implicit solution determining the seepage-face dimension formed in steady-state flow through an aquifer connecting two water bodies is achieved based on the Dupuit assumption and conservation-of-flow-rate considerations. ... -
Complexity Analyses of Sao Francisco River Streamflow: Influence of Dams and Reservoirs
(ASCE, 10/1/2020 )This study investigated the potential of methods from information science to detect hydrological alterations caused by human activity. In particular, the influence of the construction of a cascade of dams and reservoirs ... -

(ASCE, 10/1/2020 )Coastal cities of southern peninsular India are characterized by highly seasonal rainfall during a few weeks of a year, a long dry-weather period, flat topography, and shallow groundwater levels. This study investigated ... -
Investigating the Role of Hydrological Model Parameter Uncertainties in Future Streamflow Projections
(ASCE, 10/1/2020 )Calibrated hydrological models forced with the climate data from various climate models have been widely employed for future streamflow projection. But a major cause of concern in such an analysis has been the suite of ... -
Assessing the Effects of Urban Landscape Area and Pattern Change on Flood Events in Qinhuai River Basin, China
