RISEffect of Irrigation and Climate Variability on Water Quality of Coastal Watersheds: Case Study in Alabama
Publisher: American Society of Civil Engineers
Abstract: Agricultural activities are considered the leading cause of surface water quality degradation in the United States. While agricultural production in the state of Alabama is mainly rain-fed, irrigation is currently being ...
Comprehensive Drought Assessment Tool for Coastal Areas, Bays, and Estuaries: Development of a Coastal Drought Index
Publisher: ASCE
Abstract: The interface of freshwater and saltwater plays an important role in the economic and social dynamics along the coast and estuaries. Droughts in coastal areas have ecological impacts and affect socioeconomic dynamics and ...
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 ...
Developing Probability-Based IDF Curves Using Kernel Density Estimator
Publisher: American Society of Civil Engineers
Abstract: Many hydraulic structures are designed based on intensity-duration-frequency (IDF) curves. A design based on an inaccurate design storm can cause problems, such as malfunction of the infrastructure, excessive cost, or loss ...
Developing Rainfall Intensity-Duration-Frequency Curves for Alabama under Future Climate Scenarios Using Artificial Neural Networks
Publisher: American Society of Civil Engineers
Abstract: Hydrologic design of water management infrastructures is on the basis of specific design storms derived from historical rainfall events available in the form of intensity-duration-frequency (IDF) curves. However, it is ...
Sensitivity of Groundwater Components to Irrigation Withdrawals during Droughts on Agricultural-Intensive Karst Aquifer in the Apalachicola–Chattahoochee–Flint River Basin
Publisher: American Society of Civil Engineers
Abstract: In southwestern Georgia, increased groundwater withdrawal for irrigation in the Lower Flint River Basin (LFRB) is greatly affecting the supply of freshwater to downstream regions during drought years. This study was ...
Development of Community Water Deficit Index: Drought-Forecasting Tool for Small- to Mid-Size Communities of the Southeastern United States
Publisher: American Society of Civil Engineers
Abstract: The El Niño Southern Oscillation (ENSO) climate-variability phenomenon greatly affects water availability in the Southeast United States. For example, it is well known that La Niña conditions bring drought to this region. ...
Deriving Spatially Distributed Precipitation Data Using the Artificial Neural Network and Multilinear Regression Models
Publisher: American Society of Civil Engineers
Abstract: Precipitation is the primary driver for hydrologic modeling. Because hydrologic models often require long-term, spatially distributed precipitation data sets for calibration and validation, a novel approach was developed ...
Long-Range Hydrologic Forecasting in El Niño Southern Oscillation-Affected Coastal Watersheds: Comparison of Climate Model and Weather Generator Approach
Publisher: American Society of Civil Engineers
Abstract: Streamflow forecasting is essential for the proper management of water resources, especially when severe droughts cause water resource scarcity. Streamflow forecasting using physically based or conceptual hydrologic models ...
