<br />Term <br />Triangulated <br />Irregular Network <br />Model (TIN) <br /> <br />Topography <br /> <br />Universal Transverse <br />Mercator (UTM) <br /> <br />Vector Images <br /> <br />Definition <br />A significant alternative to the regular raster of a DEM that has been <br />adopted in numerous GIS progranIS and automated mapping and <br />contouring packages. The TIN model was developed in the early 1970's as <br />a simple way to create a surface from a set of irregularly spaced points. <br /> <br />. <br /> <br />Configuration (relief) of the land surface; the graphic delineation or <br />portrayal of that configuration in map form, as by contour lines. <br /> <br />The Universal Transverse Mercator (UTM) projection and grid system <br />was adopted by the U.S, Army in 1947 for designating rectangular <br />coordinates on large-scale military maps. UTM is currently used by the <br />United States and NATO armed forces. The UTM system divides the earth <br />into 60 zones each 6 degrees oflongitude wide. <br /> <br />A collection of connected lines and curves that produce objects. When <br />creating a vector image in a vector illustration program, node or drawing <br />points are inserted and lines and curves connect notes together. This is the <br />same principle as "connect the dots". Each node, line and curve is defined <br />in the drawing by the graphics software by a mathematical description, <br />Every aspect of a vector object is defined by math included node position, <br />node location, line lengtlI and on down tlIe line. Text objects are created <br />by connecting nodes, lines and curves, Every letter in a font starts out as a <br />vector object. Vector images are object-oriented while raster images are <br />pixel oriented. <br /> <br />. <br /> <br />Water Surface Profile A graph that shows the relationship between the vertical elevation of the <br />top of flowing water and of the streambed with the horizontal distance <br />along the stream channel. <br /> <br />Rule 5. State Rel!ulatorv Floodplain: The regulatory floodplain is the lOa-year floodplain. "Storm or <br />Floodwater Runoff Channels" are within the lOa-year floodplain, Sections 24-65,1-101 & 24-65.1- <br />202(2)(a)(I) and 24-65,1-302(1)(b)&(2)(a) and 24-65.1-403(3) and24-65.1-404(3), C.R.S. (2004) <br />deems the designation of floodplains a matter of statewide importance and interest and gives the <br />CWCB the responsibility for the designation of the lOa-year floodplain. <br /> <br />Rule 6.

This rule contains standards for approximate and detailed floodplains. <br />a. Approximate floodplain information will be based on detailed hydrology computed for <br />the lOa-year flood. Hydraulic information shall be produced using approximate, field, <br />or limited teclmiques and best available topographic/survey data. <br />b. Detailed floodplain information will be based on detailed hydrologic and hydraulic <br />determinations for the 100-year flood. Flood profiles and floodplain delineations for <br />the lOa-year flood and other frequencies, if any, shall be plotted, preferably using a <br /> <br />. <br /> <br />10 <br /> <br />DRAFT <br />
