Areal-reduction factors for the precipitation of the 1-day design storm in Texas by William H Asquith Download PDF EPUB FB2

The effective depth can be calculated by multiplying the design-storm depth by an areal-reduction factor (ARF). ARF ranges from 0 to 1, varies with the recurrence interval of the design storm, and is a function of watershed characteristics such as watershed size and shape, geographic location, and time of year that the design storm occurs.

Asquith Abstract The reduction of the precipitation depth from a design storm for a point to an effective (mean) depth over a watershed often is important for cost-effective design of hydraulic structures by reducing the volume of Size: 1MB.

USGS Areal-Reduction Factors for the Precipitation of the 1-Day Design Storm in Texas. Areal reduction factors (ARFs) specific for Texas for a 1-day design storm were developed by Asquith (). Asquith’s method uses an areal reduction factor that ranges from 0 to 1. The unit hydrograph assumes that the rainfall over a given area does.

is a spreadsheet tool in current use by the Texas Department of Transportation (TxDOT) engineers and other design engineers for estimating intensity-duration-frequency (IDF) of design rainfall by county; the tool differs from discrete-duration IDF in that it facilitates estimation for real-value durations (not discrete durations).

This real-value duration capability is a great. Title: Analysis of Rainfall Data for Use in Design of Storm Sewer Systems Author: Arnell, V.

Asquith, W. Depth-Duration Frequency of Precipitation for Texas, US Geological Survey Water-Resources Investigations ReportAustin, TX. ARF range from 0 to 1, vary according to storm characteristics, such as recurrence interval; and are a function of watershed characteristics, such as watershed size, shape, and geographic location.

This paper presents a new approach for estimating ARF and includes applications for the 1-day design storm in Austin, Dallas, and Houston, by: A design storm is the precipitation point depth having a specified duration and frequency (recurrence interval).

Effective depths are often computed by multiplying point depths by areal-reduction factors (ARF). ARF range from 0 to 1, vary according to storm characteristics, such as recurrence interval.

By Author: William H. Asquith. A design storm is the precipitation point depth having a specified duration and frequency (recurrence interval). Effective depths are often computed by multiplying point depths by areal-reduction factors (ARF).

ARF range from 0 to 1, vary according to storm Cited by:   The adjustment of precipitation depth of a point storm to an effective (mean) depth over a watershed is important for characterizing rainfall-runoff relations and for cost-effective designs of hydraulic structures when design storms are considered.

A design storm is the precipitation point depth having a specified duration and frequency (recurrence interval).Cited by: In the design flood estimation procedure, the areal reduction factor (ARF) is used to convert ground-level point rainfall records into areal design rainfall for a reference area.
