Modeling One-Dimensional Nonreactive Solute Transport in Open Channel Flows Under Uncertain Flow and Solute Loading Conditions
(ASCE, 8/1/2020 1)The study of solute transport processes in open channel flows is important for water quality management and environment protection. Solute transported in open channel flows is usually uncertain because of the underlying ... -
New Semi-Analytical Model for an Exponentially Decaying Pumping Rate with a Finite-Thickness Skin in a Leaky Aquifer
(ASCE, 8/1/2020 1)Pumping tests are commonly used to estimate aquifer parameters during field work. Classical pumping tests are mainly classified into two general types: constant-rate pumping tests and constant-head pumping tests. However, ... -
AR-GARCH with Exogenous Variables as a Postprocessing Model for Improving Streamflow Forecasts
(ASCE, 8/1/2020 1)The common strategy for real-time streamflow forecasting involves a precalibrated rainfall-runoff model for streamflow simulation together with a statistical postprocessing model of simulation errors for updating simulated ... -
Multiobjective Optimization of Sensor Placement for Precipitation Station Monitoring Network Design
(ASCE, 9/1/2020 1)An optimal sensor placement of a precipitation station network should fulfill different regulations and requirements, such as coverage maximization, easy access, and uniform distribution. However, few studies have focused ... -
Applicability of Lumped Hydrological Models in a Data-Constrained River Basin of Asia
(ASCE, 8/1/2020 1)A representative of meteorological data-constrained basin, Ayeyarwady, in Myanmar, Southeast Asia, is set for flow simulation and forecasting at 15 locations using a range of hydrological modeling approaches: conceptual ... -
Estimating Impacts of Dam Development and Landscape Changes on Suspended Sediment Concentrations in the Mekong River Basin’s 3S Tributaries
(ASCE, 7/1/2020 1)The Mekong River Basin (MRB) is undergoing rapid dam development, which is altering the river suspended sediment concentration (SSC). In this study, we used satellite remote sensing records spanning 31 years to detect ... -
Spatial Analysis of Flood Susceptibility Throughout Currituck County, North Carolina
(ASCE, 8/1/2020 1)A probabilistic approach to flood susceptibility determination is investigated in this paper. Nonclimatic flood risk factors are considered and used to develop a base for flood potential prior to investigating the potential ... -
Artificial Neural Networks–Based Model Parameter Transfer in Streamflow Simulation of Brazilian Atlantic Rainforest Watersheds
(ASCE, 7/1/2020 1)This paper presents an assessment of the calibration and transfer of artificial neural networks (ANNs) to simulate streamflow at Brazilian Atlantic Rainforest basins. Primary data consisted of rainfall and a streamflow ... -
Comparison of Point Precipitation Frequency Analyses of Storm-Typed Maxima and Overall Maxima for a Region in Eastern Tennessee
(ASCE, 8/1/2020 1)In frequency analysis of point precipitation extremes, one approach that has been suggested is to segregate precipitation data by storm type. Thus, for short-duration (e.g., 2-h) extremes, only observations from ... -
Estimating the Hyporheic Depth Beneath a Pool-Riffle Bedform Using the Rankine Body Analytical Method
(ASCE, 8/1/2020 1)The hyporheic zone connects groundwater and surface water allowing active exchange of water and solute, and thus plays a vital role in many hydrological and ecological processes. Many sophisticated high-dimensional models ... -
Modified Signal-to-Noise Ratio Method for Early Detection of Climate Change
(ASCE, 8/1/2020 1)Efficient climate change detection is vital to mitigate the ill effects of climate change. Several methods of change point detection have been proposed earlier that do have some limitations. Nonparametric Mann–Whitney–Pettit ... -
Cluster Analysis of Hourly Rainfalls Using Storm Indices in Peninsular Malaysia
(ASCE, 7/1/2020 1)Storm-event analysis (SEA) is a method of extracting information from rainfall data by defining rainfall events as storm events. A profile-based model in SEA defines storm events using the interevent time definition (IETD), ... -
Comparison of Nonstationary Regional Flood Frequency Analysis Techniques Based on the Index-Flood Approach
(ASCE, 7/1/2020 1)Regional flood frequency analysis (RFFA) techniques are used in hydrological applications for estimation of design quantiles at ungauged sites or catchments with sparse observational records. The index-flood method, a ... -
Attribution of Hydrologic Changes in a Tropical River Basin to Rainfall Variability and Land-Use Change: Case Study from India
(ASCE, 8/1/2020 1)In recent decades, several parts of the world have been facing severe droughts and frequent floods against a background of anthropogenic influences and changes in climatic variables. For efficient management and adaptation ... -
A Risk Assessment of a Water-Sand Inrush during Coal Mining under a Loose Aquifer Based on a Factor Analysis and the Fisher Model
