<br />c. J- - <br /> <br />computed using an iterative process. The effect of bridges <br />and culverts on the water surface profile will be included <br /> <br />in the analysis. <br /> <br />II. BASINS AND SUB-BASIN PARAMETERS <br /> <br />The initial phase of the study will involve definition <br /> <br />of the physical and hydrological characteristics of the <br /> <br />various sub-basins within the Gore Creek drainage. Factors <br />such as slope, basin aspect (north, south, etc.), soil and/or <br />rock cover, vegetal cover as I'lell as length and shape would <br />be established for each sub-basin to be used as minimal <br /> <br />aerial units. The effects on runoff of the various lakes, <br /> <br />such as the Black Lakes on Black Gore Creek would be defined <br />.~ such that the configuration of the unit hydrographs can be <br />properly delineated. The Forest Service open files on soil <br /> <br />cover, particularly the "A" horizon in the Gore basin would <br /> <br />/ be researched as a part of determining infiltration rates. <br /> <br />III. DESIGN STORM HYDROLOGY <br /> <br />The design storm hydrology involves analyzing the <br /> <br />'/ <br /> <br />available data from the Weather Bureau, Forest Service and <br /> <br />independent meteorological stations to determine if sufficient <br />short term rainfall data (1 hr" 2 hr., 6 hr., and 12 hr.) <br /> <br />are available to establish rainfall depth-duration-frequency <br /> <br />curves for the Gore Creek basin. Based upon a preliminary check <br />
