Evaluation of Multi- and Many-Objective Optimization Techniques to Improve the Performance of a Hydrologic Model Using Evapotranspiration Remote-Sensing Data
(ASCE, 2020)In this study, we explore the use of different multi- and many-objective calibration approaches in hydrological modeling when considering both observed streamflow and remotely sensed actual evapotranspiration (ETa). Eight ... -
Evaluating the Effect of Transpiration in Hydrologic Model Simulation through Parameter Calibration
(ASCE, 2020)The effect of evapotranspiration (ET) on water redistribution in hydrological models has already been explored in many studies, but whether correcting plant transpiration (EP) in a hydrologic model can play a comparable ... -
Multivariate Modeling of Projected Drought Frequency and Hazard over India
(ASCE, 2020)India is one of the most drought-vulnerable countries in the world and faces at least one drought in one region or another every 3 years. To alleviate drought risk, an efficient policy framework is needed for water ... -
Operational Comparison of Rainfall-Runoff Models through Hypothesis Testing
(ASCE, 2020)Assessing rainfall-runoff model performance and selecting the model best suited are important considerations in operational hydrology. However, model choice often is heuristic and based on a simplistic comparison of a ... -
Margin of Safety in TMDLs: Natural Language Processing-Aided Review of the State of Practice
(ASCE, 2020)The margin of safety (MOS) accounts for uncertainties in the total maximum daily load (TMDL) development process and the variabilities involved in simulating systems, providing a complete description of the degree of ... -
Development of Topography-Based River Width Estimation Model for Medium-Sized Mountainous Watersheds
(ASCE, 2020)River width is an essential physical variable for the simulation of rainfall-runoff processes using distributed hydrologic models. In this paper, a model of river width integrating the effects of an upstream drainage area ... -
Verification of a New Spatial Distribution Function of Soil Water Storage Capacity Using Conceptual and SWAT Models
(ASCE, 2020)The Soil Conservation Service Curve Number (SCS-CN) method is widely used in conceptual rainfall-runoff models for describing the runoff response with a curve, which is a function of the cumulative storm rainfall and ... -
Real-Time Control Algorithm for Enhancing Operation of Network of Stormwater Management Facilities
(ASCE, 2020)The deployment of real-time control (RTC) technology has improved the performance of stormwater management facilities. However, most of the current research focuses on individual pilot sites. The major challenge hindering ... -
Uncertainties of Precipitable Water Calculations for PMP Estimates in Current and Future Climates
(ASCE, 2020)Probable maximum precipitation (PMP) is the design criterion for many hydraulic and hydrologic structures. Despite its significance in water resource engineering, estimation of PMP values carries uncertainties. On the other ... -
Probabilistic Structure of Extreme Run Lengths in a Stationary Hydrologic Time Series
(ASCE, 2020)Current probabilistic methods for maximum and minimum run lengths in a hydrologic time series need further development. Using the first-order Markov chain model and an extreme-value theory for randomly occurring events, ... -
Generalized Split-Sample Test Interpretation Using Rainfall Runoff Information Gain
(ASCE, 2020)Rainfall-runoff conceptual models are used largely for river discharge prediction, for waterworks design, and as support for water quality assessment. The generalized split-sample test (GSST) recently was recommended to ... -
Analysis of Effect of Rainfall Patterns on Urban Flood Process by Coupled Hydrological and Hydrodynamic Modeling
(ASCE, 2020)Urban flooding poses an increasing threat to citizens and property and has become a global challenge. The primary cause of urban flooding is rapid urbanization, which is outpacing infrastructure development and drainage ... -
Hybrid Hydrological Data-Driven Approach for Daily Streamflow Forecasting
(ASCE, 2020)Hydrological forecasting is key for water resources allocation and flood risk management. Although a number of advanced hydrological forecasting methods have been developed in the past, daily (or subdaily) forecasting ... -
