Exploration of Daily Rainfall Intensity Change in South Korea 1900–2010 Using Bias-Corrected ERA-20C
(ASCE, 7/1/2020 1)Rainfall frequency analysis has been routinely adopted for the estimation of design rainfall for a specific return period. Annual maximum rainfall data are generally used for frequency analysis in practice, but the parameters ... -
Coastal Aquifer Protection from Saltwater Intrusion Using Abstraction of Brackish Water and Recharge of Treated Wastewater: Case Study of the Gaza Aquifer
(ASCE, 7/1/2020 1)Coastal aquifers are threatened by saltwater intrusion (SWI), which leads to degradation of groundwater quality by raising salinity. SWI occurs due to human activities such as overabstraction or natural processes such as ... -
Gridded Extreme Precipitation Intensity–Duration–Frequency Estimates for the Canadian Landmass
(ASCE, 6/1/2020 1)Subdaily precipitation gauging stations are limited and unevenly distributed across Canada. To support the design of sustainable stormwater infrastructure, especially in the data-sparse regions of Canada, this study presents ... -
PCA, CCA, and ANN Modeling of Climate and Land-Use Effects on Stream Water Quality of Karst Watershed in Upper Green River, Kentucky
(ASCE, 6/1/2020 1)Climate and land-use impacts on stream water quality in a karst watershed were studied to determine how they might be useful to model stream water quality parameter (SWQP) distribution from diffuse source pollution. This ... -
Curve Number Calibrations on 204 Australian Catchments
(ASCE, 6/1/2020 1)The Australian water balance model (AWBM) is automatically calibrated to 204 data sets from the main stream-gauging network in Australia. This daily rainfall-runoff model calculates surface runoff and baseflow as separate ... -
Climate Change Adaptation to Extreme Rainfall Events on a Local Scale in Namyangju, South Korea
(ASCE, 5/1/2020 1)Preparing for the impacts of climate change, especially extreme rainfall events, is not a “one size fits all” process. Exhaustive case studies must be reported to understand the impact of climate change in a local area. ... -
Comparing Discharge Computation Methods in Great Lakes Connecting Channels
(ASCE, 6/1/2020 1)Records of discharge for the connecting channels within the Great Lakes Basin are important to national governments of Canada and the United States and the various water management agencies and users in the basin. For more ... -
Analysis of Hydrologic Regime Changes Caused by Dams in China
(ASCE, 4/1/2020 1)Dam construction has significantly altered natural flow regimes and caused various environmental problems. This study analyzes hydrologic changes on a national scale using indicators of hydrologic alteration (IHA) and the ... -
Spatiotemporal Variation of Water Availability under Changing Climate: Case Study of the Upper Girna Basin, India
(ASCE, 5/1/2020 1)The present study quantifies the variation in water balance components of the semiarid Upper Girna basin (UGB), Maharashtra, India, and the flow quantiles of a dam downstream of the UGB under changing climate using the ... -
Impact of Eastern Tibetan Plateau Glacier Melt on Land Water Storage Change across the Yangtze River Basin
(ASCE, 3/1/2020 1)The Qinghai-Tibet Plateau (QTP) glaciers have been consistently retreating for decades and accelerating their retreat in recent years. It would impact the river water resources that originate from the QTP, such as the ... -
Impacts of Streamflow and Topographic Changes on Water Level during the Dry Season of Poyang Lake, China
(ASCE, 3/1/2020 1)Poyang Lake is the largest freshwater lake in China and is internationally recognized as an important lacustrine and wetland ecosystem with abundant biodiversity. Since 2003, the average lake water level has significantly ... -
Anthropogenic Impacts on Streamflow-Compensated Climate Change Effect in the Hanjiang River Basin, China
(ASCE, 1/1/2020 1)The relative importance of climate change and anthropogenic impacts on hydrology in the Hanjiang River Basin in China have become a hot topic because it has been manipulated by multiple activities, including reservoir ... -
Predicting Channel Conveyance in the Obion River Watershed Using SAMBLE Method
(ASCE, 2/1/2020 1)Digital elevation models (DEMs) are widely used for hydraulic modeling, but one of the challenges in using a DEM for hydraulic modeling is its limitations in accurately representing the channel conveyance. This limitation ... -
Identifying Regional Models for Flow Duration Curves with Evolutionary Polynomial Regression: Application for Intermittent Streams
(ASCE, 1/1/2020 1)Regional models of flow duration curves (FDC) are ubiquitous components in water resources studies, particularly in ungauged sites or in catchments with scarce monitoring. The identification of such models in arid regions, ... -
Impact of ENSO, Global Warming, and Land Surface Elevation on Extreme Precipitation in India
(ASCE, 1/1/2020 1)The linkages of precipitation extremes with large-scale global climatic phenomenon such as global warming, the El Niño–Southern Oscillation (ENSO), and the land surface elevation were explored across India. Temporally, the ... -
Combining Postprocessed Ensemble Weather Forecasts and Multiple Hydrological Models for Ensemble Streamflow Predictions
(ASCE, 1/1/2020 1)Ensemble streamflow prediction (ESP), which is generally achieved by combining ensemble weather forecast (EWF) and hydrological model, has a wide application. However, the EWF is biased and underdispersive, and therefore ... -
Mean Velocity and Entropy in Wide Channel Flows
