Estimation of Total Drainable Water Storage Using GRACE in the Brahmaputra River Basin, India
(American Society of Civil Engineers, 2024)As the Brahmaputra is a transboundary river, the availability of river flow and hydrometeorological data is less in the public domain for the Brahmaputra river basin. Hence, estimation of water balance is difficult for the ... -
Estimating Reservoir Sedimentation Using Machine Learning
(American Society of Civil Engineers, 2024)Several reservoirs across the United States are filling with sediment, which jeopardizes their functionality and increases maintenance costs. USACE developed the Reservoir Sedimentation Information (RSI) system to assess ... -
Chaos Analysis and Prediction of Monthly Runoff Using a Two-Stage Variational Mode Decomposition Framework
(American Society of Civil Engineers, 2024)Variational modal decomposition (VMD) has proven to be an effective technique for improving the accuracy of runoff prediction and has been widely used in runoff analysis and prediction. However, the presence of noise and ... -
A Probabilistic Runoff Prediction Model Based on Improved Long Short-Term Memory and Interval Correction
(American Society of Civil Engineers, 2024)Accurate and reliable runoff prediction is essential for the efficient operation of hydropower systems. This paper presented a runoff probability prediction model that utilizes an enhanced long short-term memory (LSTM) ... -
Developing Customized NRCS Unit Hydrographs for Ungauged Watersheds in Indiana
(American Society of Civil Engineers, 2024)The Natural Resources Conservation Service (NRCS, formerly the Soil Conservation Service, SCS) unit hydrograph (UH) is one of the most commonly used synthetic UH methods for hydrologic modeling and engineering design all ... -
Modeling Saltwater Intrusion into Groundwater Using a Prey–Predator Model
(American Society of Civil Engineers, 2024)Saltwater intrusion in a coastal region is one of the major issues facing the agricultural, domestic, and industrial sectors. Groundwater withdrawal for an increasing population and agricultural and industrial demands are ... -
Hypothesis Testing for the Difference between Two Nash–Sutcliffe Efficiencies for Comparing Hydrological Model Performance
(American Society of Civil Engineers, 2024)The Nash–Sutcliffe efficiency (NSE) is now the most widely used criterion for measuring the goodness of fit between the hydrological model simulation and corresponding observation. Because there is substantial sampling ... -
Test of Trapezoidal Hyetograph Method with Laboratory Watershed Data
(American Society of Civil Engineers, 2024)Trapezoidal hyetographs are common in both real-world small watersheds and laboratory watersheds because (1) real-world hyetographs are often represented by line charts that can be divided into multiple trapezoidal ... -
Application of a Workflow to Determine the Feasibility of Using Simulated Streamflow for Estimation of Streamflow Frequency Statistics
(American Society of Civil Engineers, 2024)Streamflow records from hydrologic models are attractive for use in operational hydrology, such as a streamflow frequency analysis. The amount of bias inherent to simulated streamflow from hydrologic models is often unknown, ... -
Application of Hybrid AI Models for Accurate Prediction of Scour Depths under Submerged Circular Vertical Jet
