Sediment transport in storm sewers
… effect of roughness in the sediment transport in sewers. This model was later tested against experimental data obtained from a test rig. The rig had a pipe which was specially fabricated in two halves so that it could be divided to coat the interior with uniform sand grains to provide roughness. …

Development and analysis of computer aided design and drafting software for storm sewers
… the IBM personal computer that aids engineers in storm sewer design and drafting. The most unique feature of this software package is its extensive use of the AutoCAD graphics system. The software package uses AutoCAD to enter storm sewer data. Drainage areas, sewer line locations, type of …

The Impact of Rochester Storm Sewers on the Water Quality of the Lower Genesee River: A Modeling Approach Using PCSWMM
… Canal due to industrial and municipal sources, storm sewers, and urban runoff. In urban areas, nonpoint source pollution from stormwater runoff is known to be a dominant factor in water quality. An assessment of the lower Genesee River was initiated to determine impacts from the canal, storm …

A comprehensive environmental and economic sustainability assessment of roadway drainage systems
… as a construction material (basins, culverts, storm sewers, and pipe underdrains) consistently had significantly larger environmental impacts than drainage components that did not use concrete (grass swales and bioswales). While the concrete consistently dominates environmental impacts, it does …

A stormwater management analysis of Blacksburg, Virginia
Many aspects of managing stormwater runoff were investigated for the Town of Blacksburg, Virginia, that would minimize the costly installation and environmentally damaging impacts of storm sewers as the town urbanizes. These aspects included the technical, political, financial, legal, and …

An assessment of household hazardous waste collection
… them in landfills or pouring them down drains or storm sewers. The most popular method of addressing the problem of household hazardous waste is that of holding "collection days," at which householders are encouraged to bring their hazardous waste to some central location for proper handling by …

Determining the distribution and fate of mercury in sediments of the Cataraqui River at Kingston, Ontario
… sources of Hg to sediments, soils, runoff and storm sewer discharges near high concentration sediments were measured for THg. Hg was not detected in storm sewers, but was detected in terrestrial soil near the Kingston Rowing Club at a concentration of more than 4000 μg/kg. Significant [THg] was …

motus et re-creation: Movement and re-creation on accotink creek
… spines dense with aquatic life to de-facto storm sewers, with thick foliage merely masking severe erosion and paltry ecosystems. Quite simply, the speed at which the water is pushed down the ever-narrowed corridors as paved development encroaches, coupled with pollution from this fast …

Hydraulic efficiency of grate and curb inlets for urban storm drainage
Stormwater runoff from an urban landscape is typically conveyed through networks comprised of streets, gutters, inlets, storm sewer pipes, and treatment facilities. Objectives of this research program included evaluating the hydraulic efficiency of three storm-drain inlet types and developing …

Effect of urban street pattern on drainage.
In cities, storm runoff is usually collected in the streets and conveyed to underground storm drains through inlets located at street level. Construction and maintenance of storm drain systems is always expensive. In semiarid regions with a very low frequency of storm occurrence, most cities use …

Lateral outflow from supercritical channels
Stormwater pollutants caused by urban runoff are a major concern for the Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA), and other flood control authorities, as stormwater channels eventually are discharged into natural waterways. One method of improving stormwater quality is …
