Hydrologic impacts due to application of dust suppressants
… to application of dust suppressants. Changes in runoff characteristics were investigated in the field, using a rainfall simulator on plots (which represented disturbed land surfaces) treated with 11 different dust suppressants. Results of the study indicate a general increase in the runoff …

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) …

Some Statistical Analyses of the Climate of Nacogdoches, Texas for Applications in Natural Resources Management
… maximum storm intensity, and hay production. Runoff coefficient for La Nana Creek was 0.30 and maximum flood stage was 286.41 ft. above sea level. Flow duration patterns of the Creek may have been altered significantly by urbanization in the recent 9 years.</p>

Development and analysis of computer aided design and drafting software for storm sewers
… program calculate the drainage area, weighted runoff coefficient and the time of concentration. This software allows the engineer to design and later make changes in the configuration of a storm sewer system quickly and easily.

Assessment of surface water availability in Solwezi River Basin, NothWestern Province, Zambia
… and water abstraction were analyzed using Runoff coefficient approach, Thornthwaite and Water Balance methods to determine inflows and outflows in the catchment. The water balance model developed revealed that the total inflows of the surface runoff generated in the catchment was …

An Investigation of the Performance of a Constructed Wetland in Treating Urban Stormwater
… of a constructed wetland treating stormwater runoff from a residential townhome complex in Manassas, Virginia. The facility was constructed by retrofitting a dry detention basin to retain a permanent shallow pool and included additional temporary storage to detain roughly the first half inch …

Rainfall Organization and Geomorphologic Controls on the Flood Response of Mild-slope Basins in the South Atlantic Region of US
… number of storm events by computing the event runoff coefficient based on streamflow observations and through simulations from a semi-distributed hydrological model. Comparison of observed to simulated hydrographs from the hydrological model shows that distributed rainfall forcing gives …

Observation des influences du changement du couvert forestier sur le comportement hydrologique de grands bassins versants tropicaux à l'aide de la télédétection numérique cas du bassin versant de Dong Nai, Viet Nam
… changes of outlet water and yet on the yearly runoff in terms of large watershed. In order to exceed the limitations of actual methods, to solve the difficulty of acquiring forest cover data and to have a better understanding of the relation between tropical forest cover change and hydrological …

Modeling the hydrologic and particulate loadings from paved urban surfaces
… particulate matter found in urban rainfall-runoff and urban snowmelt. Three forms of the power law model (PLM) were used to model particle number density. It was found that significant model error could be introduced into PLMs when the median diameter particle was used to estimate the number …
