A Simplified urban runoff model is descrised, on which development work was started in the midseventies with the aim of estimating the runoff volumes from town areas /Salamin 1973, kontur 1976/. The objective of the study was to develop a method of estimating the flow to the primary conveying elements, viz. The gutters and sewers. LOKASI: Ruang Koleksi Umum Rak: 4

The main objective of this paper is to define with the graetest possible degree of accuracy the position of isochrones on small ungaged watersheds and to use these isochrones to obtain a direct runoff hydrograph employing the genetic method. The essential problem is to determine correct overland flow parameters, particularly the depth of overland flow and the resistance coefficient. LOKASI: …
Tsukuba town is chosen as a case study area, for more than thirty of research instiutions were moved into this area as anational projects and there observed rafid urbanization. A Typical change of hydrograph pattern caused by urbanization was cleary observed between the one obtained in the before-construction-period and that in the after-construction-period.

The paper shows how the "two-reservoir" model for urban storm runoff (nussey and sarginson, 1978) combined with a standard design storm profile can be used to compute explicit values of the maximun discharge from the pipe system draining an urban area, and the pipe sizes necassary to carry those discarges without surcharging. Using the model, there is no need for an i terative prosess beginning…
Urban storm drainage research has been conducted on the clifton grove estate Catchment, Nottingham, since 1976 and in that time aspects of both the quality and quantity of strom water runoff have been investigated (Fletcher et al, 1978, Fletcher & Pratt, 1981, Pratt & Henderson, 1981). The catchment has a total area of 10.6 ha which 42% are impervious highway and roof surface, draining to a sep…
