Developing and Evaluating the Composite Runoff Index Geographic Model for Urban Rainfall-Runoff Modeling
<p>Urban runoff index estimation, which has traditionally been a time-consuming and labor-intensive process, is a fundamental problem for modeling watershed runoff especially for growing cities that lack stream gages worldwide. The research developed and evaluated the composite runoff index (RIc) …

Thunderstorm runoff in southeastern Arizona.
Almost all runoff-producing rainfall on small watersheds (100 square miles and less) in southeastern Arizona results from air-mass thunderstorms. On large watersheds (1,000 square miles and greater) frontal systems which may include thunderstorm activity or snowmelt produce the major flood peaks as …

First Flush Characterization of Storm Water Runoff
… characterization of first flush in storm water runoff from elevated roadways, to assist the establishment of a storm water program and to facilitate the selection of treatment technology. Storm water runoff from highways transports a significant load of contaminants, especially heavy metals and …

Phosphorus Losses in Runoff from Virginia Soils
… research shows that dissolved P losses in runoff are well related to soil test P (STP), thus, various P loss prediction models incorporate the use of a STP vs. runoff DRP relationship. However, the relationship between STP and runoff DRP will vary based on soil type due to differences in …

Treatment of urban stormwater runoff by sedimentation
… could be achieved by sedimentation of stormwater runoff. Seven runoff samples were collected from shopping centers, which were selected because of their large impermeable surfaces resulting in high pollutant concentrations. The sampling sites were also representative of locations where detention …

Quantifying Glacier-Derived Summer Runoff in Northwest Montana
… Simulated glacier-melt hereafter "glacier runoff" from within gauged basins was then compared to measured stream discharge for the month of August to assess the relative contribution of glacier runoff to stream flows. We find the fraction of August stream discharge potentially derived from …

Recovery of Antibiotic Resistance Genes From Agricultural Runoff
… indicator bacteria (FIB), and release of ARGs in runoff over six storm events. Two FIB (Escherichia coli and enterococci) and two ARGs (sulI and ermB) were quantified in runoff from each of the constructed plots throughout the growing season. FIB and ARGs were recovered from all plots, including …

A comprehensive modeling approach for urban rainfall - runoff simulation
… proposed in this work; finally, urban rainfall - runoff simulations were carried out accounting for different spatial and temporal resolutions of rain data and further mitigation effect of rain garden. In pure surface flow modeling, depth-dependent roughness and infiltration methods were …

Buildup/Washoff Model for Dissolved Iron in Stormwater Runoff
… New Orleans, Louisiana. Storm water runoff from the examined elevated roadway section was analyzed for 14 storm events. The model used a linear function of antecedent dry time for the buildup model. The rating curve assumption was selected to estimate the pollutant transport capacity. …

Temperature-index modelling of runoff from adeclining Alpine glacier
… which contribute a large proportion of therunoff from this highly-glacierised basin. As the mass of ice has declined, recessionof many smaller tributary glaciers has resulted in their separation from the trunkGornergletscher. Declining glacier surface area might be expected to have reduced …
