  Description:
    Abstract:  
       This metadata file (pbrchseg.met) describes three shape files used. 
       Shape file rivreach.shp contains the upstream and downstream
       boundaries of seven reaches of the river. Natural features define
       river-reach boundaries at the confluence of the North and South
       forks of the Coeur d'Alene CdA River, the transition from a 
       gravel- to a sand- bottomed channel, the mouth of the river, and 
       the base of the delta front. Other river-reach boundaries are at
       midpoints between river-channel drill transects. River-reach
       boundaries provide end limits for Estimation Units, for which 
       thickness, volume, tonnage, and lead content of Pb-rich sediment
       were estimated.

       Shape file segments.shp contains up- and down-valley boundaries 
       of 3 sections of the CdA River valley (upper, middle, and lower), 
       each subdivided into three segments (a, b, and c). We defined these
       valley sections and segments to facilitate definition and description
       of along-valley differences in the character of deposits of metal-
       enriched sediment. These boundaries also define east- and west-end 
       limits of Estimation Units, for which thickness, volume, tonnage, 
       and lead content of Pb-rich sediment were estimated.

       Shape file Pb1000.shp outlines the area within which samples of 
       surface sediment contain at least 1,000 parts per million (ppm).
       This outline is the 1,000 ppm Pb contour, which defines the 
       geochemical limit (or cutoff concentration for Pb) of Estimation 
       Units, for which thickness, volume, tonnage, and lead content of
       Pb-rich floodplain sediment were estimated.

    Purpose:   
       This data set was prepared as part of an effort to portray the 
       distribution, character, quantity, and Pb content of Pb-rich sediment
       in the CdA River valley. This is basic information needed to estimate
       the extent of environmental damage, and evaluate alternative strategies 
       for environmental remediation and restoration.

    Supplemental_Information:
       This Metadata (pbrchseg.met) describes three shape files (segments.shp,
       rivreach.shp, and Pb1000.shp) of the six shape files used. The 
       segments.shp shape file contains the locations of boundary lines 
       between floodplain segments (or reaches). The rivereach.shp shape file
       contains the river-reach boundaries for the area of study. The Pb1000  
       shape file contains the information needed to generate a theme in 
       ArcView, outlining the area covered by Pb-rich surface sediment, 
       containing at least 1,000 ppm of lead.

       Metadata cdafldpl.met describes three shape files used 
       (cdasurf4_utm.shp, fldpln2.shp, and fpaream2.shp). 
       
       Metadata pbsamthk.met describes two dBase4 files used
       (alsamPb.dbf and thkpb11.dbf).

    Process_Step:
      Process_Description:
       The shape file, rivreach.shp, was created in ArcView by digitizing 
       author-defined river-reach boundary lines on-screen, at scales of 
       1:24,000 or larger, using a hand-operated mouse. These boundaries
       were drawn in the context of information in the following themes: 
       1. generalized map of surficial geology and wetlands
       (cdasurf4_utm.shp), 2. geochemical sample sites (alsamPb.dbf), 
       and 3. Pb-rich sediment-thickness sites (thkpb11.dbf).       

       The shape file, segments.shp, was created in ArcView by digitizing 
       author-defined valley-section and valley-segment boundaries 
       on-screen, at scales of 1:24,000 or larger, using a hand-operated
       mouse. These boundaries were drawn in the context of information
       in the following themes:1. generalized map of surficial geology
       and wetlands (cdasurf4_utm.shp), 2. geochemical sample sites
       (alsamPb.dbf), and 3. Pb-rich sediment-thickness sites
       (thkpb11.dbf). 

       The shape file, Pb1000.shp, was created in ArcView by digitizing an 
       author-defined 1,000-ppm-Pb contour line, primarily controlled by 
       data points contained in alsamPb.dbf. Digitization was done 
       on-screen, at scales of 1:24,000 or larger, using a hand-operated 
       mouse. For purposes of area estimation, a preliminary shape file
       was digitized for each river reach and valley segment (as defined
       in rivreach.shp and segments.shp). Each of these preliminary shape
       files was used to measure the combined areas of polygons of 
       particular map units (of cdasurf4_utm.shp) within an Estimation
       Unit (defined to include polygons of a certain map unit, within the
       1,000 ppm Pb contour, and between the ends of a particular river reach
       or valley segment). To prevent double-counting of parts of polygons
       that overlap boundaries of Estimation Units, those parts of polygons 
       extending outside an Estimation Unit were clipped, and their
       areas were subtracted from that unit. However, to generate shape
       file Pb1000.shp, all river-reach and valley-segment files were 
       combined into one file (Pb1000.shp). In that file, entire areas of
       polygons that overlap Estimation-Unit boundaries are included in 
       adjoining river reaches or valley segments. Therefore, this
       file (Pb1000.shp) cannot be used to measure the square kilometers
       of surface area covered by Pb-rich sediment, because parts of 
       polygons that overlap Estimation-Unit boundaries are doubly included.
