Treatment of urban and highway stormwater runoff for dissolved and colloidal pollutants
The design of three stormwater treatment facilities, aiming at implementing and demonstrating technologies that efficiently reduce diffuse urban pollutant loads onto receiving waters is presented. The designs aim at reducing not only particulates, but also dissolved pollutants and pollutants associated with colloids. Unit operations that are efficient in this respect are discussed. Different te...

هدف اصلی این تحقیق مقایسه و تمایز بین روشها و استراتژیهای خاص برای درک مطلب بهتر در زبان مادری و زبان دوم بوده است. در قدم اول میزان توانایی افراد در درک مطلب فارسی و انگلیسی اندازه گیری و سپس رده بندی شد. همچنین از دانش آموزان خواسته شد که در مورد روشها و استراتژیهایی که برای درک مطلب بهتر به کار برده بودند توضیح دهند. نتیجه این مرحله از تحقیق نشان داد که دانشجویان برای درک مطلب مطلوب در زبان ...
15 صفحه اولDesign Tool for Controlling Runoff and Sediment from Highway Construction
Regulations require that stormwater pollution prevention plans be developed for construction activities that disturb an area that is equal to or greater than one acre. Different strategies, including a combination of practices, can be used to develop these plans. The WATER model was a tool developed from a previous project to assess the effectiveness of different on-site sediment control practi...
متن کاملToxicity of urban highway runoff with respect to storm duration.
The toxicity of stormwater runoff during various time-based stages was measured in both grab and composite samples collected from three highly urbanized highway sites in Los Angeles, California between 2002 and 2005. Stormwater runoff samples were tested for toxicity using three freshwater species (the water flea Ceriodaphnia dubia, the fathead minnow Pimephales promelas, and the green algae Ps...
متن کاملModeling highway runoff pollutant levels using a data driven model.
Pollutants accumulated on road pavement during dry periods are washed off the surface with runoff water during rainfall events, presenting a potentially hazardous non-point source of pollution. Estimation of pollutant loads in these runoff waters is required for developing mitigation and management strategies, yet the numerous factors involved and their complex interconnected influences make st...
