Model-Based Analysis of the Effects of Rippled Bed Morphologies on Hyporheic Exchange
(ASCE, 2020)Groundwater–surface water (GW-SW) exchange processes are important due to their critical role in controlling the transport of pollutants and ecologically related materials in rivers. In this paper, the surface water–groundwater ... -
River Levee Overtopping: A Bivariate Methodology for Hydrological Characterization of Overtopping Failure
(ASCE, 2020)This research presents a bivariate methodology for the hydrological characterization of the overtopping failure for an existing river levee. Conventional procedures usually consider only one variable for the hydrologic ... -
Optimization and Variants of Quantile-Based Methods for Bias Corrections of Statistically Downscaled Precipitation Data
(ASCE, 2020)New optimization and variants of quantile-based methods are developed for bias corrections of monthly and daily general circulation model (GCM)-based statistically downscaled precipitation data. These methods use optimization ... -
Measurement and Estimation of Water Retention Curves Using Electrical Resistivity Data in Porous Media
(ASCE, 2020)The soil water retention curve (SWRC) is significant for predicting soil physical properties and solute processes. However, the existing methods for obtaining SWRC are mainly focused on laboratory measurements and have ... -
Probability Distribution of Waiting Time of the kth Extreme Event under Serial Dependence
(ASCE, 2020)Negative binomial distribution has been suggested to describe the first arrival time of the kth flood exceeding the design flood under independence and both stationary and nonstationary conditions. However, hydrological ... -
Toward Simple Modeling Practices in the Complex Canadian Prairie Watersheds
(ASCE, 2020)The prairie region in Canada has been characterized as a graveyard of hydrological models due to its challenging cold-regions processes and complex landscape with numerous land depressions that influence runoff pathways. ... -
Nonstationary Based Framework for Performance Enhancement of Coastal Flood Mitigation Strategies
(ASCE, 2020)The flood protection topic has been the centerpiece of many studies due to the amplification of coastal vulnerabilities, especially on the east coast of the United States. In this study, increasing the reliability of the ... -
Evaluating Uncertainty in Fluvial Geomorphic Response to Dam Removal
(ASCE, 2020)Dam removal tends to produce a series of changes in river morphology. Whereas decisions pertaining to dam removal are typically evaluated from a deterministic viewpoint, this study develops a stochastic framework for ... -
Simultaneous Regionalization of Gauged and Ungauged Watersheds Using a Missing Data Clustering Method
(ASCE, 2020)Use of flood statistics in the regionalization of watersheds may improve the homogeneity of regions. However, it is not possible to use the feature vectors, including the flood statistics, to estimate the flood quantiles ... -
Drain Time for Porous Stormwater Basin
(ASCE, 2020)Porous basins are popular low-impact-development (LID) facilities for on-site runoff disposal and water quality enhancement. Bioretention basins and rain gardens are recommended to intercept the initial runoff up to the ... -
Climate-Related Trends of Within-Storm Intensities Using Dimensionless Temporal-Storm Distributions
(ASCE, 2020)Huff curves are probabilistic time distributions of rainfall expressed as dimensionless cumulative percentages of storm depth and duration. Previous studies have documented development factors, spatial robustness, and the ... -
Long-Term Periodic Modeling in Hydrology: Role of Sunspot Cycles
(ASCE, 2020)Solar irradiation is the dominant source of energy driving hydrologic phenomena on the Earth. This study is a step toward investigating the statistical significance of the relationship between hydrologic data and persistent ... -
Assessment of Artificial Recharge Dams and Improvement of Their Groundwater-Recharge Capacity
(ASCE, 2020)Construction of recharge dams across highly permeable beds of alluvial streams is one of the most important techniques used for artificial groundwater recharge from muddy surface runoffs. To assess recharge dams, the Meymand ... -
River Flow Prediction Using Dynamic Method for Selecting and Prioritizing K-Nearest Neighbors Based on Data Features
(ASCE, 2020)River flow prediction is an important aspect of robust water resources planning and flood warning systems operation. Data-driven approaches have been found efficient to this end. K-nearest neighbors (KNN) is a lazy learning ... -
