Technical Note #15 from Watershed Protection Techniques, I(1):30-31, covering sources of urban stormwater pollutants as defined in Wisconsin. Based on Bannerman, R., D. Owens, R. Dodds, and N. Hornewer (1993) study published in Water Science & Technology (28):3-5, pp. 241-259. Over 300 runoff samples collected from 46 micro-sites in two watersheds. Documents pollutant concentrations of

Technical Note #13 from Watershed Protection Techniques 1(1):28, summarizing a Santa Clara Valley Nonpoint Source Program study on metal pathways into the Lower San Francisco Bay. Cars and vehicles found to produce over 50% of total loads of copper, cadmium, and zinc; brake pad wear alone accounts for 50% of total copper load; tire wear

This document is a project schedule (Gantt chart) for a Water Resources Analysis. It outlines tasks, durations, start and finish dates, and dependencies across multiple phases of the analysis, including data collection, feasibility studies, permitting, and report preparation.

This document outlines the Washington State Department of Ecology’s presumed position on stormwater mixing zones, covering when stormwater becomes water of the state, design storm approaches for acute and chronic zones, critical receiving water conditions, and background concentration considerations. It also addresses circumstances under which mixing zone size criteria exceedances may be allowed, referencing WAC

This document presents a frequency analysis of the lowest monthly mean flows (August-May) for Miller Creek below ROF, covering 48 years of data ranked by flow magnitude, with a 5-year return period mean low flow of approximately 0.60 cfs. A second page presents daily and hourly flow data from a 2-year/72-hour storm event in August

National Research Council publication by the Committee on Mitigating Wetland Losses, Board on Environmental Studies and Toxicology, and Water Science and Technology Board titled ‘Compensating for Wetland Losses Under the Clean Water Act.’ AR034586, Exhibit-2178. Covers mitigation compliance standards including jurisdictional hydrology, wetland delineation, hydrological performance standards, design standards for mitigation sites, USACE wetland filling

This document presents a joint probability analysis for the 3RWN (Third Runway North) ambient and effluent discharge conditions, including a 3D surface plot of joint probability values across ambient and effluent percentiles. A detailed table correlates joint probability values with time percentages, dilution factors (minimum, maximum, mean, and standard deviation), and the number of unique
