The capacity of a soil to accept, conduct, and purify effluent cannot be expressed by percolation tests or by hydraulic conductivities at saturation alone. Field tests are available now to measure complete K-curves and application to many soils in Wisconsin has shown that four different types of curves can be distinguished. Effects of biological clogging or mechanical compaction, or puddling on infiltration into the soil are examined, considering different levels of the water table and using a simple one-dimensional flow theory. Results of in situ monitoring with tensiometers of 12 seepage systems in different soils and design criteria, some tentative, for innovative systems in a wide range of soils are considered. Use of soil survey information for purposes of extrapolation of research results from tested to untested sites is recommended.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"21 1","pages":"967-983"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75343538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diversion studies evaluated fish guidance to variously angled screen and louver arrays. A bypass system was designed by which diverted specimens can be returned safely to sea. Entrainment reduction studies with modeled intake structures led to development of a circular capped structure featuring uniform entrance velocity and a horizontal run prior to a vertical drop. Fish avoidance of various sounds was explored.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"17 1","pages":"897-910"},"PeriodicalIF":0.0,"publicationDate":"1975-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74656533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A linear programming model for screening the sizes and operating policies of conduits and storage and treatment facilities is formulated. The objective function is to minimize costs. The constraint set maintains physical continuity, sizes the facilities, and specifies water quality objectives. The paper also describes the EPA Storm Water Management Model, which is a detailed simulation model of combined sewer flows. The paper shows how the EPA model can be used interactively with the screening model to plan for the control of combined sewer overflow and local flooding. A case study is made on the Bloody Run Drainage Basin, Cincinnati, Ohio. The results of the case study indicate that the screening model and the planning method are reliable.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"394 1","pages":"807-820"},"PeriodicalIF":0.0,"publicationDate":"1974-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74970386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conclusions of the Master Plan are based on extensive studies of existing facilities, present and future conditions, and the effects on the receiving waters of alternative plans. A real time computer based data acquisition system has been installed with 30 tipping bucket rain gages and 120 flow monitors with level gages. The Master Plan compares separate dry and wet weather improvements to combined facilities tied together with a computer based automated control system. Different treatment levels are utilized during dry weather. A variable range of storage-solids treatment combinations are utilized with split treatment during wet weather.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"54 1","pages":"1013-1032"},"PeriodicalIF":0.0,"publicationDate":"1974-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76664346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
