Routing Field Channels through a Tertiary Unit with Heterogeneous Fields
(ASCE, 9/1/2021)The extensive irrigation systems of South Asia are predominately a hierarchy of canals delivering water to a tertiary unit. A network of field channels transfers water within the tertiary unit to the field where it is ... -
Evaluation of Minor Losses in Connectors Used in Microirrigation Subunits Using Machine Learning Techniques
(ASCE, 8/1/2021)The proper hydraulic design of microirrigation system subunits requires the characterization of minor losses. To this end, machine learning models based on artificial neural networks [multilayer perceptron (MLP)], support ... -
Three-Dimensional Numerical Modeling of Urban Green Stormwater Infrastructure Curb Inlets
(ASCE, 9/1/2021)The current equations for curb inlet opening sizing often inaccurately estimate the capture efficiency of small urban green stormwater infrastructure (GSI) curb inlets. Most of these equations are based on studies with ... -
Numerical Modeling of Soil Water–Heat Transport under Oxo-Biodegradable Film Mulch and the Optimal Mulching Period
(ASCE, 9/1/2021)Timely monitoring and regulation of the transport and distribution of soil water and heat are appropriate methods to ensure and improve crop yields. With the degradation of the oxo-biodegradable film, the upper boundary ... -
Compost for Permanent Vegetation Establishment and Erosion Control along Highway Embankments
(ASCE, 8/1/2021)Erosion management is a major environmental challenge facing highway construction. A research study was undertaken to analyze possible sustainable improvements to current standard procedures for final grade turfgrass ... -
Hydraulic Performance Evaluation of Wattles Used for Erosion and Sediment Control
(ASCE, 7/1/2021)Land disturbing construction activities can become nonpoint sources of pollution, particularly due to suspended sediment, if erosion and sediment control measures are ineffective. Wattles have become popular practices among ... -
Flow Decomposition Method Based on Computational Fluid Dynamics for Rock Weir Head-Discharge Relationship
(ASCE, 8/1/2021)Typical engineering design of rock weirs rely on simplified one-dimensional equations dependent on empirical coefficients. However, most simplified methods fail to accurately predict the hydraulics through rock weirs because ... -
Sustainable Residential Landscapes in Florida: Controlled Comparison of Traditional versus Florida-Friendly Landscaping
(ASCE, 7/1/2021)A comparison of water use and maintenance effort was made between traditional and Florida-Friendly Landscaping (FFL). Traditional Florida landscapes are generally turf dominated with minimal shrubbery, all indiscriminately ... -
Experimental and Numerical Investigations of Flow over and under Weir-Culverts with a Downstream Ramp
(ASCE, 7/1/2021)A series of experimental and numerical studies were conducted to investigate the hydrodynamics of weir-culverts with a downstream ramp in submerged-flow condition. A comparison of the numerical and experimental results ... -
Comprehensive Evaluation of Machine Learning Techniques for Hydrological Drought Forecasting
(ASCE, 7/1/2021)Drought is among the most hazardous climatic disasters that significantly influence various aspects of the environment and human life. Qualitative and reliable drought forecasting is important worldwide for effective ... -
