<br />AMERICAN WATER RESOURCES ASSOC'N. <br />1975: -Urbanisation and water quality <br />control-. American Water Resources <br />ASSOc., Proc. No.20: 294pp. <br /> <br />Key words: water pollution sources: <br />nonpoint pollution sources: urban hy- <br />drology; urban runoff: urbanisation. <br /> <br />. <br /> <br />This publication contains nearly 48 pa- <br />pers on the quantitative and qualita- <br />tive contribution of urban areas to <br />surface water and, to a lesser extent, <br />ground water, with most of the ex~mples <br />coming from the U.S.A. Various types <br />of nonpoint source pollution are dis- <br />cussed, and the necessity for a proper <br />appreciation of the effects of planning <br />decisions on hydrological conditions at <br />an early stage of future land develOp- <br />ment is stressed. The conference posed <br />the question of the extent to which <br />urban runoff clean-up is a political <br />rather than a technical problem. <br /> <br />. <br /> <br />A~Y, G. et al. 1974: "Water quality man- <br />agement planning for urban runoff". <br />EPA 440/9-75-~04, prepared by URS, Inc. <br />(NTIS Pll-241 669). <br /> <br />Kev words: waste water <br />analytical techniques: <br />pollution; urban runoff: <br />runoff= pollution abatement. <br /> <br />treatment: <br />water <br />storm <br /> <br />. <br /> <br />This manual provides technical assis- <br />tance to state and local water quality <br />management plann~rs to enable them to <br />quantify within reasonable limits the <br />urban nonpoint water pollution problem <br />in a local planning area without exten- <br />sive data generation, and to make a <br />preliminary evaluation of cost effeC- <br />tive abatement and control practices. <br />The manual prescribes procedures for <br />several levels of input, each requiring <br />more self generated data, with increas- <br />ingly sophisticated results. ~ <br />'state-of-the-art' and an extensive bi- <br />bliography on urban storm water runoff <br />is presented in the appendix a ~ glos- <br />sary is also included. The manual is <br />not intended to be used for abatement <br />design but does provide a guide to data <br />generation for this purpose. <br /> <br />ANDERSEN, D.R. 1975: .Water quality models <br />for urban and suburban areas". Office <br />of Water Research Technology, Dept. of <br />the Inter ior; 1I4pp. (NTIS PB-238 <br />622). <br /> <br />Key words: <br />mathematical <br />gen demand: <br />nitrates~ <br />bacteria; <br />ids. <br /> <br />surface runoff; <br />models; biochemical oxy- <br />chemical oxygen demand: <br />phosphorus compounds; <br />pesticides: suspended 501- <br /> <br />. <br /> <br />Urban storm runoff was sampled and ana- <br />lysed for various pollutional parame- <br />ters. Data obtained were used in the <br />development of modeling techniques for <br />SimUlating the quality and quantity of <br />runoff. A hydrograph simulation model <br />developed by the Department of Computer <br />Science at the University of Nebraska <br />was used to generate flow hydrographs <br />comparable to observed runoff data. <br />Modeling t~chniques similar to those <br />used in the EPA Storm Water Management <br /> <br />Model were used for modeling COO, BOD, <br />and solidsa Data were also obtain~cl <br />relative to concentrations of nitrogen. <br />phosphorus, pesticides and bacteria in <br />the runoff. Data generally confirmed <br />the 'flush effect' of pollutants at th~ <br />s!art of the runoff period. These data <br />also showed that urban storm water may <br />contain significant amounts of pollu- <br />tants.

The de- <br />gree of effect decreases with incre~s- <br />ing flood magnitude. <br /> <br />ANDERSON, D.G. 1978: "Effects of urban de- <br />velopment on floods in Northern Virgi- <br />nia-.
