Simple Method for the Design of Microirrigation Paired Laterals on Sloped Fields
(American Society of Civil Engineers, 2010)In this study, a method for designing paired laterals that meet with required water application uniformity on sloped fields was developed using the energy gradient line approach based on the definition of the best submain ... -
Cost-Estimating Tools for Low-Impact Development Best Management Practices: Challenges, Limitations, and Implications
(American Society of Civil Engineers, 2011)Tools were developed for estimating costs of vegetative roofs, rainwater catchment systems, and bioretention facilities. These tools provide a detailed framework to facilitate cost estimation for capital costs, operation ... -
Combining Remotely Sensed Data and Ground-Based Radiometers to Estimate Crop Cover and Surface Temperatures at Daily Time Steps
(American Society of Civil Engineers, 2010)Estimation of evapotranspiration (ET) is important for monitoring crop water stress and for developing decision support systems for irrigation scheduling. Techniques to estimate ET have been available for many years, while ... -
Sediment Monitoring Bias by Automatic Sampler in Comparison with Large Volume Sampling for Parking Lot Runoff
(American Society of Civil Engineers, 2011)A field study was conducted to assess biases of suspended sediment concentration (SSC) analyses (ASTM Standard D3977-97) performed on discrete samples obtained by automatic sampler in comparison with actual sediment ... -
Assessing Pressure Changes in an On-Demand Water Distribution System on Drip Irrigation Performance—Case Study in Italy
(American Society of Civil Engineers, 2010)The hydrant pressure head in an on-demand water distribution system can be subject to high fluctuation depending on the discharge flowing inside the pipes, with consequent impacts on the performance of on-farm irrigation ... -
Impacts of Media Depth on Effluent Water Quality and Hydrologic Performance of Undersized Bioretention Cells
(American Society of Civil Engineers, 2011)Fill media and excavation volume are the main costs in constructing bioretention cells, but the importance and impact of media depth in these systems is relatively unknown. Two sets of loamy-sand-filled bioretention cells ... -
Modified Horton’s Equation to Model Advance Trajectory in Furrow Irrigation Systems
(American Society of Civil Engineers, 2010)A modified form of Horton’s infiltration equation was used to model advance trajectory of the wetting front as well as for predicting cumulative infiltration in a furrow-irrigated system using experimental data obtained ... -
