Analytical Solution of Kinematic Wave Equation for Overland Flow due to Storms Moving at a Velocity Lower than Flow Velocity
(ASCE, 2023/11/01)Overland flow is often generated by moving rainstorms and is modeled using the kinematic wave theory. In overland flow modeling, it is usually assumed that rainstorms are stationary and occur over the entire watershed. ... -
Evaluating the Efficacy of Actively Managed Distributed Storage Systems for Peak Flow Reduction Using Spatially Uniform Design Storms
(ASCE, 7/22/2023 )Extreme rainfall in midwestern United States has gotten more common over the last half century, thus increasing flooding events across the region. As a result, traditional flood mitigation measures are commonly overwhelmed ... -
Flow and Colloid-Facilitated Contaminant Transport in the Vadose Zone: Numerical Study
(ASCE, 8/30/2023 )The present paper focuses on the numerical model development of the colloid-facilitated contaminant transport using an equilibrium approach in the vadose zone of subsurface porous media. Flow in the vadose zone of subsurface ... -
Improved Velocity Profile in Open Channels Using Incomplete Information–Based Entropy Theory
(ASCE, 8/15/2023 )A new measure of entropy based on incomplete information theory has been proposed in the literature for deriving velocity profiles in open-channel flow. This entropy is a one-parameter generalization of the Shannon entropy, ... -
Rainfall Forecasting with Hybrid and Machine Learning Models Based on Hyperparameter Optimization
(ASCE, 8/23/2023 )Time-series analysis in hydrology plays an important role in the efficient use of water resources, prediction of flood risks, and crop production. However, considering many parameters in the solution of hydrological problems ... -
Rainfall–Runoff Process Simulation in the Karst Spring Basins Using a SAC–Tank Model
(ASCE, 6/20/2023 )Rainfall–runoff simulation is the basis of basin flood forecasting and water resource planning. However, karst basins are highly nonhomogeneous. With the intermittent uplift of the Earth’s crust, karst landscapes with large ... -
Hydrological Frequency Analysis in Changing Environments Based on Empirical Mode Decomposition and Metropolis-Hastings Sampling Bayesian Models
(ASCE, 7/7/2023 1)The consistency of hydrological sequences has been affected by climate change and human activities, resulting in significant uncertainty in the results of hydrological frequency analysis. The Mann-Kendall test and Hurst ... -
Study on Temporal Variability of Hydrological Elements in the Daqing River Basin, China
(ASCE, 8/24/2023 )To reveal the temporal variability of hydrological elements in the Daqing River Basin (TDRB), an index system with temporal variability indices of hydrological elements, namely jump variability, trend variability, and ... -
Combined Impact of Density Stratification and Hindered Settling on Nonequilibrium Suspended Sediment Transport in Open Channel Flows
(ASCE, 5/27/2023 )The present paper studies the two-dimensional unsteady suspended sediment transport problem through an open channel turbulent flow that carries large amounts of sediments. Presence of large amounts of sediments causes ... -
Potential Hydrologic Pathways of Deicing Salt Chloride Transport Evaluated with SWMM
(ASCE, 5/27/2023 )Deicing salts are a major contributor to freshwater salinization in the Northeastern United States, disrupting ecosystem function, aquatic life, and infrastructure integrity. It is often presumed that surface runoff is the ... -
