Aggradation of Irrigation Canal Network in Žitný Ostrov, Southern Slovakia
(American Society of Civil Engineers, 2010)The objective of this paper is to investigate and analyze the silting and subsequent aggradation of the irrigation canals in Žitný Ostrov (Rye Island). The irrigation canal network, located in Southern Slovakia, was built ... -
Investigation of Flow through Orifices in Riser Pipes
(American Society of Civil Engineers, 2010)In this study the discharge coefficient for circular orifices of different size in two different sizes of riser pipe is investigated experimentally. This type of outlet structure is common in detention ponds to achieve ... -
Infilling Missing Daily Evapotranspiration Data Using Neural Networks
(American Society of Civil Engineers, 2010)This study used artificial neural networks (ANNs) computing technique for infilling missing daily saltcedar evapotranspiration (ET) as measured by the eddy-covariance method. The study site was at Bosque del Apache National ... -
Evaluation of Microirrigation Uniformity on Laterals Considering Field Slopes
(American Society of Civil Engineers, 2010)Water application uniformity is an important performance criterion that must be considered during the design and evaluation of the microirrigation systems. This study was conducted to evaluate the water application uniformity ... -

Effect of Roof Surface Type on Storm-Water Runoff from Full-Scale Roofs in a Temperate Climate
(American Society of Civil Engineers, 2011)Roof surfaces represent a significant portion of the impervious area associated with urban development. Storm-water runoff from those surfaces causes stream degradation in receiving waters attributable to excess volume of ... -
Field Evaluation of Four Level Spreader–Vegetative Filter Strips to Improve Urban Storm-Water Quality
(American Society of Civil Engineers, 2011)An assessment of the performance of four level spreader–vegetative filter strip (LS-VFS) systems designed to treat urban storm-water runoff was undertaken at two sites in the Piedmont of North Carolina. At each site, a ... -
Hydrologic Performance Monitoring of an Underdrained Low-Impact Development Storm-Water Management System
(American Society of Civil Engineers, 2010)The use of low-impact development (LID) storm-water management facilities will grow with gains in understanding of their performance based on field tests. An innovative flow measurement system was designed and tested for ... -

Physical Processes Resulting in Geysers in Rapidly Filling Storm-Water Tunnels
(American Society of Civil Engineers, 2011)Geysers, which involve the explosive release of water through vertical shafts connected to a nearly horizontal pipeline, have been attributed to either pipeline surge or the release of air. Laboratory experiments involving ... -
Integration of Low-Impact Development into the International Stormwater BMP Database
(American Society of Civil Engineers, 2011)Low impact development (LID) strategies are being encouraged in many communities as an approach to reduce potential adverse impacts of development on receiving streams. Many questions exist regarding how well various LID ... -
Development of Effluent Concentration Models for Sediment Scoured from Catchbasin Sumps
(American Society of Civil Engineers, 2011)The ability of catchbasin sumps and hydrodynamic separators to remove sediment must be balanced with their ability to retain the previously captured material by preventing scour. The sediment scour process in these storm-water ... -
Groundwater Mounding at a Storm-Water Infiltration BMP
(American Society of Civil Engineers, 2011)This research presents an initial study of the impacts of storm-water infiltration on a shallow unconfined aquifer at a bioinfiltration best management practice (BMP) on the campus of Villanova University. The study site ...
