Estimation of Exceedance Probability of Scour on Bridges Using Reliability Principles
(ASCE, 8/1/2021)Scour is one of the most relevant causes of bridge collapse. Most existing scour models have been focused on estimating scour depth as input for bridge design. This estimation is mainly deterministic. Parameter uncertainty ... -
Selecting Reliable Models for Total Maximum Daily Load Development: Holistic Protocol
(ASCE, 10/1/2021)Computer models and simpler methods must be used to reliably determine total maximum daily loads (TMDLs) for impaired waters of the US. Models are also useful to develop implementation plans that allocate load reductions ... -
Evaluation of Surface Evaporation Considering the Effect of Soil Water Gradient
(ASCE, 8/1/2021)Evaporation of unsaturated loess refers to the phenomenon that, under the vertical driving force, the water contained in soil moves to the evaporation surface and diffuses into the atmosphere as water vapor. This lowers ... -
Evaluating the Performance of a Hydrological Model to Represent Curbside Distributed Infiltration Wells in a Residential Catchment
(ASCE, 8/1/2021)Stormwater managers use hydrological models to understand the runoff management performance of stormwater systems in urban catchments. However, few published studies attempted to evaluate the performance of hydrological ... -
Removal of Salt Marsh–Impairing Tidal Flow Restrictions: Impact on Upstream Flooding under the Combined Influence of Rainfall and Tide
(ASCE, 7/1/2021)Restoring tidal flow to anthropogenically flow-restricted waterways provides ecological benefits while also changing the flood risk of adjacent lands. Our research evaluated the flooding risk on Tremley in Linden, New ... -
Performance of Bedload Sediment Transport Formulas Applied to the Lower Minnesota River
(ASCE, 7/1/2021)Despite limitations in reproducing complex bedload sediment transport processes in rivers, formulas have been preferred over collection and analysis of field data due to the high cost and time-consuming nature of bedload ... -
Space and Time Fractional Governing Equations of Unsteady Overland Flow
(ASCE, 7/1/2021)Combining fractional continuity and motion equations, the space and time fractional governing equations of unsteady overland flow were derived. The kinematic and diffusion wave approximations were obtained from the space ... -
Impact of Flood Types on Superposition of Flood Waves and Flood Statistics Downstream
(ASCE, 7/1/2021)Flood events may be caused by different runoff generating processes and can be differentiated in their genesis by the application of flood types. Additionally, the spatial interaction of catchments can play a crucial role ... -
Spatiotemporal Analysis of Compound Agrometeorological Drought and Hot Events in India Using a Standardized Index
(ASCE, 7/1/2021)Meteorological droughts abetted by hot events could instigate an agricultural drought that eventually affects crop yield. Different types of droughts may coexist or occur in succession. A single index based on one particular ... -
Nonlinear Expression of Groundwater Head Interval Based on the Perturbation Method
(ASCE, 8/1/2021)An investigation of a groundwater system often requires the prediction of the spatiotemporal distribution of groundwater heads, which determine the groundwater flow direction and magnitude, among other applications. How ... -
Nonoverlapping Block Stratified Random Sampling Approach for Assessment of Stationarity
(ASCE, 7/1/2021)Assessment of stationarity in any hydroclimatic time series is a vital task for hydrologic design and climate change assessments. Methods that rely on the presence of statistically significant trends or change points to ... -
Delineation of Small Flat Watershed with High-Resolution DEM from Terrestrial Laser Scanning
(ASCE, 7/1/2021)The digital elevation model (DEM) has been widely used in hydrological analysis and flood assessment. While DEMs, derived from airborne light detection and ranging (lidar) technology, have sufficient accuracy for large-scale ... -
Development of Modified Tank Model for Reservoir Storage Prediction: Case Study of Huanggang Reservoir, Fujian, China
(ASCE, 7/1/2021)Reservoirs are important water conservancy constructions for flood prevention and disaster reduction in a region. The prediction of reservoir storage is a key task to ensure its safe management and operation. In this study, ... -
Development of Intensity-Duration-Depth Relationships for Western Ghats in Karnataka, South India: A Pragmatic Approach for Utilizing Short Records
(ASCE, 6/1/2021)Popular models currently available for estimation of design intensities in the wet mountainous Western Ghat areas of South India are not those based on analysis of local rainfall records. Possibilities of development of ... -
Bayesian Approach for Estimating the Distribution of Annual Maximum Floods with a Mixture Model
(ASCE, 6/1/2021)Annual flood peaks frequently stem from distinct flood-producing mechanisms. However, most inference procedures rely on a single distributional model, which can lead to ill-posed inferences of its upper-tail behavior. For ... -
Stormwater Quality Capture Volume for Mitigating Urban Runoff Impacts
(ASCE, 5/1/2021)Porous basins have been recommended for stormwater onsite infiltration and filtering purposes. The effectiveness of a porous basin is often evaluated by its long-term storm runoff capture rate. The key factors for estimating ... -
Connection between Meteorological and Groundwater Drought with Copula-Based Bivariate Frequency Analysis
(ASCE, 7/1/2021)Groundwater is a major resource of freshwater that provides additional resilience to agricultural drought during rainfall deficit and also helps in understanding the nature of the hydrological drought risk of an area. This ... -
Reverse Flood Routing in Rivers Using Linear and Nonlinear Muskingum Models
(ASCE, 6/1/2021)One of the key factors for flood modeling and control is the flood hydrograph, which is not always available due to lack of flood discharge observations. In reverse flow routing, hydraulic or hydrological calculations are ... -
