# Stochastic Empirical Loading and Dilution Model (SELDM) output: 2013-03-10 13:24:26 # # # SELDM Lake-Analysis Output File # # # Version: 1.0.0 # March 2013 # Granato, G.E., 2013, Stochastic empirical loading and dilution model (SELDM) version 1.0.0: U.S. Geological # Survey Techniques and Methods, book 4, chap. C3, 112 p., CD–ROM. (Also available at http://pubs.usgs.gov/tm/04/c03/) # Initial Release # # This file includes total highway and lake-basin flows and loads by annual load accounting year. # it also includes annual average lake concentrations and detention times by annual load accounting year. # See: ExampleAnalysisI81Out.txt for the explanation and disclaimers. # # Annual Lake-Output Sequence # The lake analysis is based on two independent annual lake-output sequence components. The highway-runoff # component is generated storm-by storm in the main SELDM model. The lake-basin contributions are not # calculated on a storm-by-storm basis. The lake-basin flux, concentrations and loads are generated for # each day during the entire period, aggregated into annual sums, and paired with the highway-runoff # component. The selected streamflow statistics, adjusted for the entire lake-basin drainage area) are # used to generate all daily values. Individual daily values should not be exported and used for further # analysis because SELDM generates each value randomly without serial correlation or seasonal patterns. # The annual-load accounting years are just random collections of 365 or 366 sequential daily values. # Lake flux years are assigned to highway-runoff analysis years by paring values that are sorted on total # annual streamflow volume and total annual precipitation volume, respectively. # # # Analyst(s): # Role: Primary analyst # Initials/Short Name: Anonymous # Additional Information: # The Anonymous profile is the default for hypothetical use # # # Project Information: # Short Title: z01 Example Project # Title: Example Project Z01 # Number: FHWA-EIS-200X-XX-D # Organization: # Federal Highway Administration # Abstract: # This is an example project that can be used to experiment with the SELDM model # # # GIS Grid Information: # The grid is used to discretize geographic data for use within the database # Short Title: SELDM 0.25 degree Conterminous U.S. # Grid Information: # A 0.25 degree grid for the conterminous U.S. developed for the SELDM model # # # Analysis Information: # Example Analysis (I-81) # Description: Example highway analysis I-81 Near Harrisburg PA # Type: Stream and Lake Analysis # Status: Draft # # # Ecoregion Information: # Group: USEPA Level III Ecoregion # Citation: # U.S. Environmental Protection Agency, 2003, Level III ecoregions of the continental United States: # Washington, D.C., U.S. Environmental Protection Agency National Health and Environmental Effects Research # Laboratory, 1 pl. # Ecoregion Number: 67 # Ecoregion Name: Central Appalachian Ridges and Valleys # Description: # This northeast-southwest trending, relatively low-lying, but diverse ecoregion is sandwiched between # generally higher, more rugged mountainous regions with greater forest cover. As a result of extreme # folding and faulting events, the region’s roughly parallel ridges and valleys have a variety of widths, # heights, and geologic materials, including limestone, dolomite, shale, siltstone, sandstone, chert, # mudstone, and marble. Springs and caves are relatively numerous. Present-day forests cover about 50% # of the region. The ecoregion has a diversity of aquatic habitats and species of fish. # # # Highway Site Information: # Site: I-81 Near Harrisburg PA # Name: I-81 Near Harrisburg PA at intersection of RT-944 Wertzville Rd, p21 FHWA-RD-81-045 #
