Curve Number and Runoff Coefficients for Extensive Living Roofs
(American Society of Civil Engineers, 2016)Living roofs are a green infrastructure (GI)/low-impact development (LID) stormwater control measure (SCM) increasingly drawing worldwide attention. Despite substantial performance evidence in the literature, the lack of ... -
Estimating Extreme Spatial Rainfall Intensities
(American Society of Civil Engineers, 2016)Determining the impact of catchment flooding requires an estimate of extreme spatial rainfall intensity. Current flood design practice typically converts a point estimate of rainfall intensity into a spatial rainfall ... -
Evaluation of TRMM-Precipitation with Rain-Gauge Observation Using Hydrological Model J2000
(American Society of Civil Engineers, 2017)Spatial precipitation is a major input to distributed hydrological models, and the accuracy of runoff predictions greatly depends on its accuracy. Satellite-based precipitation products are expected to offer an alternative ... -
Modeling Fen Hydrology to Inform Recovery of the Endangered Hine’s Emerald Dragonfly
(American Society of Civil Engineers, 2016)It is generally recognized that fens and the rare species they support can only be effectively managed and protected by treating them as part of a larger, connected groundwater system. However, this underlying groundwater ... -
Comparison of SWAT and DLBRM for Hydrological Modeling of a Mountainous Watershed in Arid Northwest China
(American Society of Civil Engineers, 2016)A distributed physically based model, soil and water assessment tool (SWAT), and a distributed conceptual model, distributed large basin runoff model (DLBRM), were selected to compare their applicability and performance ... -
Application of Pre-NEXRAD Reflectivity Data to Hourly Precipitation Analyses
(American Society of Civil Engineers, 2017)Multidecadal records of hourly precipitation estimates are needed to provide forcings for the simulation of subdaily processes in hydrologic models. Existing climatological datasets, such as the North American Land Data ... -
Modeling of Variably Saturated Flow in Response to Pumping from an Unconfined Aquifer: Numerical Evidence of Gravity-Delayed Drainage and Its Parameterization
(American Society of Civil Engineers, 2016)A numerical model of variably saturated axis-symmetric radial flow is employed to simulate and parameterize the gravity-delayed drainage, viewing it as the vertical accretion over falling water table. Numerical experiments ... -
Study on ENSO Modulated Seasonal Variations in Atmospheric Humidity Using Global Positioning System Radio Occultation Data
(American Society of Civil Engineers, 2016)The role of cool (La Niña) and warm (El Niño) phases of El Niño Southern Oscillation (ENSO) on seasonal variations in atmospheric humidity which has impact on hydrological cycle is studied using global positioning system ... -
Evaluating CFSR and WATCH Data as Input to SWAT for the Estimation of the Potential Evapotranspiration in a Data-Scarce Eastern-African Catchment
(American Society of Civil Engineers, 2016)One of the key inputs of a hydrological model is the potential evapotranspiration (PET), which sets an upper limit to evapotranspirative water demand. However, limited data availability often challenges the choice of a PET ... -
Genetic Programming-Based Ordinary Kriging for Spatial Interpolation of Rainfall
(American Society of Civil Engineers, 2016)Rainfall data provide an essential input for most hydrologic analyses and designs for effective management of water resource systems. However, in practice, missing values often occur in rainfall data that can ultimately ... -
Effects of Future Climate Change on a River Habitat in an Italian Alpine Catchment
(American Society of Civil Engineers, 2016)The impact of prospective climate change on the hydrological and ecological status of the mountain stretch of the Serio river (ca. 300 km2) in the Northern Italian Alps was investigated. A hydrological model was used to ... -
Dynamic Analysis of Vegetated Water Flows
(American Society of Civil Engineers, 2016)Substantial energy losses occur when water flows over vegetated ground. Vegetation enhances surface resistance and decreases flow velocity, which results in energy loss. Since the ground is considered to be permeable, both ... -
Hydrologic Web-Mapping Application of Hofmann Forest with GIS Approach: Case Study
(American Society of Civil Engineers, 2017)In this study, a hydrologic web-mapping application for North Carolina State University’s Hofmann Forest is developed using geospatial information science (GIS) resources, measured point precipitation, and radar precipitation ... -
Trends and Anomalies in Extreme Climate Indices and Influence of El Niño and La Niña over Pranhita Catchment in Godavari Basin, India
(American Society of Civil Engineers, 2016)Hydrologic design and planning requires dealing with extremes in precipitation and temperature events caused due to climate change. Long-term trends and variability in 20 extreme climate indices (ECIs) and the influence ... -
Groundwater Flow and Solute Transport Simulation in Eastern Al Batinah Coastal Plain, Oman: Case Study
(American Society of Civil Engineers, 2016)The Al Batinah coastal plain in the Sultanate of Oman is one of the area’s most treasured regions for the existence of fresh groundwater and agriculture. Growth of irrigation, urbanization, and industrial endeavors have ... -
Laboratory Analog Analysis of Spring Recession Curve in a Karst Aquifer with Fracture and Conduit Domains
(American Society of Civil Engineers, 2016)Karst aquifers differ from other types of hydrogeological systems because of their complex behavior, which originates from strong heterogeneity. A karst spring carries an imprint of hydrologic information for the karst ... -
Comprehensive Framework for Assessment of Radar-Based Precipitation Data Estimates
(American Society of Civil Engineers, 2017)Assessment of radar-based precipitation estimates using rain gauge observations is a critical exercise in evaluating pre-and postcorrected (gauge-adjusted) radar-based precipitation data. A comprehensive assessment framework ... -
Wetland Water-Level Prediction Using ANN in Conjunction with Base-Flow Recession Analysis
(American Society of Civil Engineers, 2017)This study introduces two artificial neural network (ANN)-based methodologies to predict hourly water levels (WLs) in wetlands characterized by water tables at or near the surface that respond rapidly to precipitation. The ...
