    These upland watersheds have a grass cover and swale areas that concentrate watershed runoff with no incised stream channel. Percent imperviousness is planned from 0% to as much as 40% under two spatial arrangements of imperviousness - stream-channel-connected and . 1 RESERVOIR ANALYSIS FOR STORM RUNOFF CONTROL IN URBAN WATERSHED: AN INITIAL CASE STUDY APPROACH Rodrigo B.

A case study for a small urban watershed in Fairfax County, Virginia illustrates the value of applying different methods to delineate the watershed and flow network, and forms the basis for comparative analysis.

Moreover, it provides better details in describing physical characteristics of the watershed, which led to its applicability to bigger watersheds than those in the rational method (Maidment ).Cited by:

In the syntheses of hydrograph characteristics of small urban watersheds, the distribution of water among the various phases of the runoff process is attempted by the concept of equivalent rural watershed. The urban parameters considered in the study are percentage impervious cover and characteristic impervious length by: 7.

Get this from a library. Analog computer simulation of the runoff characteristics of an urban watershed. [V V Dhruva Narayana; J Paul Riley; Eugene K Israelsen]. In the syntheses of hydrograph characteristics of small urban watersheds, the distribution of water among the various phases of the runoff process is attempted by the concept of equivalent rural watershed.

The urban parameters considered in the study are percentage impervious cover and characteristic impervious length factor. Modeling the runoff characteristics of an urban watershed by means of an analog computer.

Proceedings of a special lecture series on the effects of watershed changes on stream flow. The Hydrological Simulation Program-Fortran (HSPF), which is a hydrological and water-quality computer model that was developed by the United States Environmental Protection Agency, was employed to simulate runoff and nutrient export from a typical small watershed in a hilly eastern monsoon region of by: 9.

Pollutants in urban runoff, stemming from wash-off of soil, dust and debris from impervious surfaces, for example, are one of the leading causes of stream water quality impairment in the USA (Novotny & Olem, ).

Generally, surface runoff on impervious surfaces has greater velocities, larger volumes and shorter times to flow by: In this contribution, the characteristics of urban runoff quality are described first. Next the quality procedures used in the RUNOFF block of SWMM are presented, including the generation of pollutants (quality constituents).

The quality of stormwater is generated by two mechanisms: pollutant buildup and by: 1. Many computer depended hydrological model have been developed for simulation of runoff in watershed and water resource studies. In this study, Soil Water Assessment Tool (ArcSWAT) an extension tool has been used to simulate runoff process in Walnut Gulch watershed located in Arizona, USA over sub hourly base.

Physiographic Characteristics Drainage: The Stream Order, Drainage Pattern, and Drainage Density have a profound influence on watershed as to runoff, infiltration, land management etc.

It determines the flow characteristics and erosional behavior. If drainage density is more, peak runoff.

ANALOG COMPUTER SIMULATION OF THE RUNOFF CHARACTERISTICS OF AN URBAN WATERSHED. In the synthesis of hydrograph characteristics of small urban watersheds, the distribution of water among the various phases of the runoff process is attempted by the concept of equivalent rural by: 7.

The overall land component of the L.A. Watershed project sought to develop predictive models representing the physical, hydrological, and runoff characteristics of the watersheds that feed the coastal waters of Southern California.

In particular, the land component focused on watersheds and runoff affecting SMB. Since rainfall data is generally in abundance in comparison to runoff data, the attempt has been made to convert rainfall to runoff. Probably one of the best-known Rainfall-runoff models is the Stanford Watershed Model (SWM).

Table 1. Simulation results for Harsul watershed. The model has been applied for the three month’s rainfall data. From the simulations, it is observed that, the model is able to simulate the volume of runoff and time to peak runoff. But large variations are observed in peak Size: 1MB.

Request PDF | Liquid Analog Model for Laboratory Simulation of Rainfall–Runoff Process | A liquid analog model (LAM) is presented as a new hydrological laboratory device for rainfall-runoff.

This CD ROM contains 19 popular watershed models from the book Mathematical Models of Small Watershed Hydrology and models span a range of characteristics, such as representativeness, comprehensiveness, broad-based applicability, and use of modern tools. New Runoff Simulation Model for Small Urban Catchments The proposed method was applied to ten rainfall events gauged in two different urban catchments.

Runoff computed with the improved rational hydrograph method was compared to measured runoff, as well as to the runoff derived from the nonlinear reservoir model. Simulation models. This procedure of computing the synthetic outflow hydrograph is accomplished with the analog computer at the Utah Water Research Laboratory, Utah State University at Logan.

SINGER, P. EM6. Simulation results indicated runoff volume was on average × (±) and sediment yield × (±) greater from the urban watershed than from the forested watershed. The ratio of rainfall volume to runoff volume was on average % higher in the urban watershed compared to the forested by: to mimic the flashy runoff conditions that are usually a part of flood events in watersheds the size.
