Development Of An Effective Shade Model For Water Quality Management In Oregon, Erin Costello
Development Of An Effective Shade Model For Water Quality Management In Oregon, Erin Costello
Environmental Science and Management Professional Master's Project Reports
Warming stream temperatures degrade water quality by stressing cold-water species, promoting harmful algal blooms, lowering dissolved oxygen, and increasing the toxicity of some compounds. The influence of stream temperature on the survival of native salmon is of particular concern in the Pacific Northwest. Effective shade, the fraction of solar radiation blocked from reaching a stream, is directly related to in-stream temperature and can be manipulated by riparian management actions. Mechanistic models of effective shade are prohibitively data and cost intensive. The objective of this research was to develop an empirical model (Simple Shade) for evaluating effective shade across the state …

Coagulation And Electrocoagulation For Co-Treatment Of Stabilized Landfill Leachate And Municipal Wastewater, Mohini Verma, R. Naresh Kumar
Research outputs 2014 to 2021
Landfill leachate and municipal wastewater at various ratios (1:20, 1:10, 1:7 and 1:5) were subjected to coagulation and electrocoagulation (EC). Alum was used in conventional coagulation at pH 6 and aluminum plate as electrode was used in EC at a current density of 386 A/m2 with 5 cm inter electrode spacing. Treatment efficiency was assessed from removal of chemical oxygen demand (COD), total suspended solids (TSS), turbidity, ammonia, nitrate and phosphate. At 1:5 ratio of landfill leachate to municipal wastewater, highest COD removal was with 3.8 g/L alum whereas highest turbidity removal was with 3.3 g/L alum during coagulation. …
