Estimates of Precipitation IDF Curves and Design Discharges for Road-Crossing Drainage Structures: Case Study in Four Small Forested Watersheds in the Southeastern US
(ASCE, 4/1/2021)We compared precipitation intensity-duration-frequency (PIDF) curves developed for four small forested watersheds to spatially interpolated estimates from the National Oceanic and Atmospheric Administration’s (NOAA) Atlas-14. ... -
Evaluating the Water Level Variation of a High-Altitude Lake in Response to Environmental Changes on the Southern Tibetan Plateau
(ASCE, 5/1/2021)Lakes are sensitive to environmental changes, and an example of this change is the decreased water level in the Yamzho Yumco Lake (YYL, in southern Tibetan Plateau), which is opposite of the reported expansion in most other ... -
Design Flood and Flood-Prone Areas under Rating Curve Uncertainty: Area of Vieux-Ténès, Algeria
(ASCE, 3/1/2021)The accuracy of flood control models depends on the set of annual maximum discharge used to estimate design flood via statistical flood frequency analysis (FFA). The uncertainties associated with the discharge time series ... -
Comparison of Likelihood-Free Inference Approach and a Formal Bayesian Method in Parameter Uncertainty Assessment: Case Study with a Single-Event Rainfall–Runoff Model
(ASCE, 3/1/2021)In the present study, DREAM(ZS) and DREAM(ABC) (which stands for differential evolution adaptive metropolis) algorithms were applied to determine the parameters’ uncertainty in a single-event rainfall–runoff model, and ... -
Estimation of Water Yield under Baseline and Future Climate Change Scenarios in Genale Watershed, Genale Dawa River Basin, Ethiopia, Using SWAT Model
(ASCE, 3/1/2021)It is important to estimate the quantity and quality of water resources in terms of spatial and temporal variability to utilize such resources sustainably. Change in future climate conditions affects the availability of ... -
Characterizing Influence of Hydrologic Data Correlations on Climate Change Decision Variables: Evidence from Diyala River Basin in Iraq
(ASCE, 3/1/2021)Water resources decision-making processes involving impacts of climate change require coherent climate datasets, which may exhibit high spatial and temporal variability. These datasets are used in models with forcing data ... -
New Finite Volume–Multiscale Finite-Element Model for Solving Solute Transport Problems in Porous Media
