A Unified Framework for Deriving Extremal Hypothesis Theories of Hydraulic Geometry
(ASCE, 2022/12/01)In a river cross section or segment that has attained an equilibrium flow regime, the relationship between geometric (river depth, width, hydraulic radius, bed slope, etc.) and/or hydraulic (velocity, roughness, shear ... -
A Method Combining Seepage Theory and Model Simulation for the Identification of Potential Groundwater Resources
(ASCE, 2022/12/01)In recent years, climate change has caused extreme weather all over the world, including in Taiwan. Rainfall in Taiwan is distributed unevenly in both time and space, leading to a shortage of water resources which has ... -
Performance Evaluation of Aquifer Storage and Recovery (ASR) System in Saline Groundwater Regions: Impact of Operational Factors and Well Design
(ASCE, 2022/12/01)Application of aquifer storage and recovery (ASR) is difficult in highly saline groundwater regions because the recharged freshwater mixes with saline groundwater and makes a thin layer below the capillary fringe. The ... -
Rainstorm Combination Design during the Meiyu Season: An Example from Southern Jiangsu, China
(ASCE, 2022/12/01)Meiyu is a unique weather phenomenon in East Asia that affects the middle and lower reaches of the Yangtze River in China, as well as Taiwan, central and southern Japan, and southern South Korea. It typically occurs from ... -
Simulating Runoff and Actual Evapotranspiration via Time-Variant Parameter Method: The Effects of Hydrological Model Structures
(ASCE, 2022/12/01)Modeling methodologies capable of coping with changing catchment conditions are becoming more important and are critical to ensure credible model predictions because the hydrologic process of the catchment is inevitably ... -
Unit Hydrograph Peak Rate Factor Estimation for Texas Watersheds
(ASCE, 2022/11/01)In many cases, estimation of the peak discharge is the primary goal of hydrologic modeling. We employed a dataset of 1,648 rainfall-runoff events in 104 watersheds in Texas to explore the peak rate factor (PRF) of 2.08 ... -
Monotonic Linear Constraints for Deriving Realistic Optimal Unit Hydrographs
(ASCE, 2022/11/01)Deriving unit hydrographs from rainfall-runoff data using optimization techniques circumvents the cumbersome requirements of the conventional manual method. In one of the two main ways of formulating the optimization ... -
NRCS Curve Number Method: Comparison of Methods for Estimating the Curve Number from Rainfall-Runoff Data
(ASCE, 2022/10/01)A data set comprising rainfall-runoff data gathered at 31 Agricultural Research Service experimental watersheds was used to explore curve number calibration. This exploration focused on the calibrated value and goodness-of-fit ... -
Forcing Data Organization for the Lesser Zab River Basin in Iraq to Build a Coherent Hydrological Model
(ASCE, 2022/12/01)Two of the most challenging issues in building robust hydrological models are determining model parameter uncertainty and examining parameter sensitivity to the system forcing data. These are especially important in dry ... -
Flood-Induced Geomorphic Change of Floodplain Extent and Depth: A Case Study of Hurricane Maria in Puerto Rico
(ASCE, 2022/10/01)Rainfall from tropical cyclones (TCs) in Puerto Rico and similar environments can cause extreme riverine flooding accompanied by substantial scour, transport, and sediment deposition. These processes can alter channel and ... -
General Unit Hydrograph from Chow’s Linear Theory of Hydrologic Systems and Its Applications
(ASCE, 2022/10/01)This research solves Chow’s linear hydrologic systems equations thoroughly to result in a theoretical instantaneous unit hydrograph (UH), which is a superposition of many (M) negative exponential functions. This implies ... -
Three-Dimensional Thermal Groundwater Analysis by Localized Meshless Method and Method of Characteristics
(ASCE, 2022/12/01)This paper aims to develop an accurate and efficient numerical model for three-dimensional transient thermal groundwater flow problems. The modified Richards equation and heat transport equation are considered to govern ... -
Long-Term Streamflow Prediction Using Hybrid SVR-ANN Based on Bayesian Model Averaging
(ASCE, 2022/11/01)The Volga River, as the primary supplier of the Caspian Sea, plays a huge role in its ecosystem sustainability. In this study, we analyze its runoff predictability for different monthly forecast horizons. Additionally, the ... -
Application of General Unit Hydrograph Model for Baseflow Separation from Rainfall and Streamflow Data
(ASCE, 2022/11/01)Baseflow separation from rainfall and streamflow data is a fundamental problem in applied hydrology, unsolved despite extensive investigations. For example, a part of baseflow is interflow, which results from rainfall ... -
Multisurrogate Assisted Evolutionary Algorithm–Based Optimal Operation of Drainage Facilities in Urban Storm Drainage Systems for Flood Mitigation
(ASCE, 2022/11/01)Drainage facilities are key infrastructure elements of urban stormwater drainage system (USDSs) for flood mitigation during short-duration extreme rainstorms. To obtain the optimal operation rules of drainage facilities ...
