One of the objectives of the PLUARG Modelling Task Force is to develop an overview model of outputs of land derived pollutants subject to selected management scenarios in a search for cost-effective strategies to meet target reductions. Towards this end, a pilot model has been developed. The model is based on the conceptualization of watersheds as sets of identifiable units of specified land form and land use. These units contribute pollution loads to the main river in series from headwaters to the river mouth. To evaluate the contribution of individual units, one needs to develop unit loads for various land forms and land uses. The Hydraulics Research Division (HRD) of the National Water Research Institute was been asked by PLUARG to provide estimates of pollution loads for watershed units with urban land use and to evaluate various pollution abatement measures for urban runoff. The terms of reference of this report may be summarized as follows: (a) Provide estimates of annual unit loads of selected pollutants in urban runoff. (b) Provide estimates of efficiencies and costs of selected abatement measures for pollution due to urban runoff.
