RISSpecial Issue on Advances in Wetland Hydrology and Water Quality Processes Modeling
Publisher: American Society of Civil Engineers
Stochastic Residual-Error Analysis for Estimating Hydrologic Model Predictive Uncertainty
Publisher: American Society of Civil Engineers
Abstract: A hybrid time series-nonparametric sampling approach, referred to herein as semiparametric, is presented for the estimation of model predictive uncertainty. The methodology is a two-step procedure whereby a distributed ...
Hydrologic Modeling of an Eastern Pennsylvania Watershed with NEXRAD and Rain Gauge Data
Publisher: American Society of Civil Engineers
Abstract: This paper applies the Soil Water Assessment Tool (SWAT) to model the hydrology in the Pocono Creek watershed located in Monroe County, Pa. The calibrated model will be used in a subsequent study to examine the impact of ...
Wetland Water-Level Prediction Using ANN in Conjunction with Base-Flow Recession Analysis
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Effect of Soil Data Resolution on Identification of Critical Source Areas of Sediment
Publisher: American Society of Civil Engineers
Abstract: Identification of critical source areas (CSAs) of pollution in a watershed is important for effective implementation of best management practices (BMPs). Process-based watershed models are often used for this purpose. One ...
System Dynamics Approach for Hydropower Generation Assessment in Developing Watersheds: Case Study of Karkheh River Basin, Iran
Publisher: American Society of Civil Engineers
Abstract: In many watersheds around the world where the importance of assessing a watershed as a whole is overlooked, new water resources projects are designed solely based on historic flow data. Such projects might fail to operate ...
Wetland Water-Level Prediction Using ANN in Conjunction with Base-Flow Recession Analysis
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Impacts of Climate Change and Urbanization on Groundwater Resources in a Barrier Island
Publisher: American Society of Civil Engineers
Abstract: Coastal freshwater aquifers are highly vulnerable to climate change and other anthropogenic environmental impacts. Therefore, managing coastal freshwater for future use requires critical planning. This is especially true ...
Development and Application of a Methodology for Sediment Source Identification. I: Modified Unit Sedimentograph Approach
Publisher: American Society of Civil Engineers
Abstract: Identification of sediment source areas within a watershed is useful for designing appropriate management alternatives that reduce sediment losses. In most watersheds, data collection programs are present at the stream ...
Development and Application of a Methodology for Sediment Source Identification. II: Optimization Approach
Publisher: American Society of Civil Engineers
Abstract: In this paper, we re-examine the question of identification of source areas using optimization methods for two Iowa watersheds. The question of nonuniqueness is addressed first, with the result that only eight sediment ...
