Improving the Accuracy of Snow and Hydrological Models Using Assimilation by Snow Depth
(ASCE, 1/1/2021)The main aim of this study is to improve the underestimation of spatial snowfall distributions by using assimilation. Although measuring snowfall depth is crucial to evaluate snow water resources and predict snowmelt runoff ... -
Alterations in the Water-Level Regime of Tonle Sap Lake
(ASCE, 1/1/2021)The Tonle Sap Lake (TSL), located in southwestern Mekong Basin, is the largest freshwater lake in Southeast Asia. The water-level regime of the TSL has been changing over the last few decades due to the rapid development ... -
Variable-Sized Cluster Analysis for 3D Pattern Characterization of Trends in Precipitation and Change-Point Detection
(ASCE, 1/1/2021)A novel analysis procedure, referred to as variable-sized cluster analysis (VSCA), was developed to identify trends and change points in precipitation time series data set. The procedure involved station-scale rainfall ... -
Parameter Uncertainty of a Hydrologic Model Calibrated with Remotely Sensed Evapotranspiration and Soil Moisture
(ASCE, 3/1/2021)Remotely sensed (RS) observations are becoming prevalent for hydrological model calibration in sparsely monitored regions. In this study, the parameter uncertainty associated with a hydrological model calibrated with RS ... -
Regional Modeling of Long-Term and Annual Flow Duration Curves: Reliability for Information Transfer with Evolutionary Polynomial Regression
(ASCE, 2/1/2021)The estimation of long-term flow duration curves (FDC) and annual flow duration curves (AFDC) are frequently required for water resources planning and management at ungauged catchments. The index flow framework provides a ... -
Concept of Threshold in the Estimation of Probable Maximum Precipitation: Hershfield’s Method Revisited
(ASCE, 3/1/2021)Hershfield’s statistical procedure is recognized by the World Meteorological Organization (WMO) and widely used for estimating probable maximum precipitation (PMP). It uses the frequency factor formula, where the frequency ... -
Curb Inlet Efficiency Evaluation under Unsteady Rainfall Situations Based on Full-Scale Rainfall-Runoff Experiments
(ASCE, 2/1/2021)Bioretention facilities have commonly been used to reduce the runoff volume, peak discharge, and pollution in runoff to the downstream drainage system during sponge city construction. The curb inlet interception efficiency ... -
Exaggerated Stream Depletion in Streams with Spatiotemporally Varying Streambed Conductance
(ASCE, 2/1/2021)Stream depletion is the reduction in flow rate in a stream due to pumping in an aquifer that is hydraulically connected to the stream. We developed a semianalytical expression for stream depletion for pumping in a homogeneous ... -
Improved Generalized Calibration of an Impedance Probe for Soil Moisture Measurement at Regional Scale Using Bayesian Neural Network and Soil Physical Properties
(ASCE, 3/1/2021)Regional-scale precise soil moisture measurements are required for remote sensing-based soil moisture product validation besides, complimenting in several hydrological and agricultural applications. Though the gravimetric ... -
Development of 1D–2D Urban Flood Simulation Model Based on Modified Cellular Automata Approach
(ASCE, 2/1/2021)In the context of urban flood management, it is necessary to estimate flood depth and area accurately. Therefore, development of a flood simulation models with acceptable accuracy could be the first step to fulfill this ... -
Enhanced Long Short-Term Memory Model for Runoff Prediction
(ASCE, 2/1/2021)Runoff prediction plays a crucial role in the scheduling and management of water resources. A novel enhanced long short-term memory (LSTM) model called LN-LSTM-PSO is proposed by integrating layer normalization (LN), LSTM ... -
Evaluation of Structural Measures for Flash Flood Mitigation in Wadi Abadi Region of Egypt
(ASCE, 2/1/2021)Wadis, an Arabic term referring to a wadi, in the Eastern Desert of Egypt have undergone rapid unsustainable development in areas vulnerable to flash flooding and water scarcity. To reduce the risk of damage and loss of ... -
Diffusion Wave Approximation of Depth-Averaged Flow Interaction with Porous Media
(ASCE, 2/1/2021)A two-dimensional diffusive wave framework is proposed for modeling interaction between flow through and outside porous media. The depth-integrated parabolic model was developed with an assumption of zero temporal/convective ... -
Identification of Combined Hydrological Models and Numerical Weather Predictions for Enhanced Flood Forecasting in a Semiurban Watershed
(ASCE, 1/1/2021)Flood forecasting in urban and semiurban catchments is often limited by the capability of the combined hydrological models and forecast inputs to predict floods accurately. The objective of this research is to develop an ... -
Calibration of Concentration Parameters Based on Frequency Decomposition of Fourier Series
(ASCE, 1/1/2021)The unstable and unreasonable parameter identification results are achieved because of the nonlinear effect (e.g., the cross-autocorrelation parameters). The XAJ (Xin’anjiang) model shows a certain correlation among ... -
Comprehensive Drought Assessment Tool for Coastal Areas, Bays, and Estuaries: Development of a Coastal Drought Index
(ASCE, 1/1/2021)The interface of freshwater and saltwater plays an important role in the economic and social dynamics along the coast and estuaries. Droughts in coastal areas have ecological impacts and affect socioeconomic dynamics and ...
