Eric Bransby Williams (–) was a British actor. He was the son of Bransby Williams. Selected filmography. His Grace Gives Notice () The Sins Ye Do () The Presumption of Stanley Hay, MP () The Gold Cure () Confessions () The Secret Kingdom (). Watershed time of concentration is needed as the storm duration of the design storm used to calculate peak storm water runoff rate with the Rational Method. Get Excel spreadsheet templates from this article in U.S. or S.I. units to calculate the travel times for the components. The Manning kinematic equation is used to calculate travel time for overland sheet flow in the Excel spreadsheets. The equations are the Bransby-Williams (Eq.1), Yen and Chow’s Simplified Formula (Eq.2), National Association of Australian State Road Authorities (NAASRA) (Eq.3) and Kerby’s Formula (Eq.4). The equations are shown as follow. 11th International Conference on Urban Drainage, Edinburgh, Scotland, UK, Abustan et al. (b) The Bransby-Williams equation, with due consideration of the presence of any prominent natural stream channels (which should be accounted for by means of suitable hydraulics equations), should be used for determining the time of concentration (tc), as follows: 0. H A L tc = where tc = time of concentration (min). Feb 18, · The Bransby Williams formula for the time of concentration dates from when George Bransby Williams published a paper "Flood discharge and dimensions of spillways in India". This refers back to an earlier paper by "Mr Chamier" who noted that the: The maximum flood will generally be produced by the greatest possible rainfall of a. Apr 21, · A previous post discussed the Bransby Williams approach. Here I look at the Pilgrim McDermott formula, which is another method commonly used in Australia and relates time of concentration to catchment area (A): (hours) (equation 1) where A is measured in km 2. authors: m beran, g bransb williams, rb bulman, bransby williams Source: Proceedings of the Institution of Civil Engineers, Volume 68, Issue 1, 1 Feb (–) TECHNICAL bran-online.info by: 1.
