Physical Model of Hydrological Behavior of Permeable Pavements Using FlexPDE
(American Society of Civil Engineers, 2019)The increase of urbanization combined with the increase in impervious surfaces has led to an increasing frequency of flooding events in urban catchments. This context highlights the inadequacy of traditional urban drainage ... -
Discretization of the Generalized Nash Model for Flood Routing
(American Society of Civil Engineers, 2019)The discretization of the generalized Nash model (GNM) has been made in such a way that it can be applied easily to the sample-data system for flood routing. First, the variable Sn-curve was introduced to simplify the GNM. ... -
Streamflow Drought Interpreted Using SWAT Model Simulations of Past and Future Hydrologic Scenarios: Application to Neches and Trinity River Basins, Texas
(American Society of Civil Engineers, 2019)In water resources and environmental management, hydrologic indexes are often valued as decision support tools because of their practical interpretability. This is true with the streamflow drought index (SDI), which is ... -
Assessing Hydrologic Uncertainty Processor Performance for Flood Forecasting in a Semiurban Watershed
(American Society of Civil Engineers, 2019)A key challenge in enhancing flood forecast relies in the difficulty of reducing predictive uncertainty. The precipitation-dependent hydrologic uncertainty processor (HUP) is a flexible model independent Bayesian processor ... -
Rainfall Generator for Nonstationary Extreme Rainfall Condition
(American Society of Civil Engineers, 2019)Stochastic weather generators are generally used to produce scenarios of climate variability on a daily timescale for hydrological modeling and water resource planning applications. Most of the available weather generators ... -
Optimal Exponent Values of Distance and Elevation Based on Hourly Rainfall Data in the Modified Inverse Distance Method
(American Society of Civil Engineers, 2019)Obtaining appropriate, applicable exponent values of distance and elevation in the modified inverse distance method for hourly rainfall interpolation is difficult because the range of the exponent values has not yet been ... -
Multiparameter Regression Modeling for Improving Quality of Measured Rainfall and Runoff Data in Densely Instrumented Watersheds
(American Society of Civil Engineers, 2019)The Walnut Gulch Experimental Watershed is a semi-arid experimental watershed and long-term agro-ecosystem research (LTAR) site managed by the USDA-Agricultural Research Services (ARS) Southwest Watershed Research Center ... -
Review of Time-of-Concentration Equations and a New Proposal in Italy
(American Society of Civil Engineers, 2019)The time of concentration is a fundamental parameter used for hydrological analysis in professional and scientific communities. The availability of equations for its estimation leads to significant variability and uncertainty. ... -
Determination of Equivalent Roughness of Bridge Piers’ Flow Resistance
(American Society of Civil Engineers, 2019)The Manning equation has been widely used in rivers, with the flow resistance caused by bed roughness (n) to account for all energy loss influences associated with channel characteristics. Flow resistance also arises from ... -
Simulation–Optimization Tool for Multiattribute Reservoir Systems
(American Society of Civil Engineers, 2019)Reservoirs, as the largest water systems for controlling water and supply demands, have been particularly important due to their operational requirements. Applying practical tools to evaluate the performance of reservoir ... -
Quantifying Rainfall-Derived Inflow from Private Foundation Drains in Sanitary Sewers: Case Study in London, Ontario, Canada
(American Society of Civil Engineers, 2019)Rainfall-derived infiltration and inflow (RDII) is a major issue causing surcharge flows in many municipal sanitary sewer systems. This paper demonstrates a statistical method for characterizing the rainfall-derived inflow ... -
Evaluation of Flood Timing and Regularity over Hydrological Regionalization in Southern Brazil
(American Society of Civil Engineers, 2019)Extreme floods are often devastating, directly affecting millions of people worldwide. Because of the lack of infrastructure and proper hydrological monitoring, flood-related hazards in developing countries are magnified. ... -
Joint Probability of Extreme Streamflow and Its Day of Occurrence
(American Society of Civil Engineers, 2019)The magnitudes of peak streamflows and their return periods are important considerations in infrastructure design and hazard mitigation. Periods of high floods are usually associated with seasons and infrastructures and ... -
New Flood Early Warning and Forecasting Method Based on Similarity Theory
(American Society of Civil Engineers, 2019)The challenge of achieving reliable flood forecasting results in semiarid regions remains stark. We developed a flood early warning and forecasting method based on similarity theory and a hydrological model to extend the ... -
Hydrologic Performance of Permeable Pavement as an Adaptive Measure in Urban Areas: Case Studies near Montreal, Canada
