<br />. <br /> <br />. <br /> <br />The total precipitation depths range from 1.89 inches <br />to 2.19 inches for the 10-year frequency storm, 2.75 <br />inches to 3.18 inches for the 50-year frequency storm, <br />and 3.08 inches to 3.41 inches for the 1 DO-year fre- <br />quency storm. <br /> <br />. <br /> <br />. <br /> <br />Incremental rainfall tables for <br />1 DO-year frequency storms are <br />Appendix. <br /> <br />the 10-, 50-, <br />presented in <br /> <br />and <br />the <br /> <br />. <br /> <br />2.3 Unit Hydrograph Coefficients <br /> <br />. <br /> <br />Synder unit hydrograph coefficients were developed us- <br />ing UD&FCD recently developed criteria. The unit <br />hydrograph coefficients for each of the sub-bas ins are <br />shown in the Appendix. <br /> <br />. <br /> <br />2.4 Loss Rates & Depression Storage <br /> <br />. The loss rates calculated by the CUHPD program were <br />based on Horton' 8 variable loss rate equation (Refer- <br />ence 4). The initial 108s rate (fO final loss rate <br />. (fo) and the decay rate (x) are based on the Soil Con- <br />servation Service (SCS) hydrologic soils groups for <br />each sub-basin. The Hydrologic Soils Map located at <br />. the back of the Appendix was developed from the SCS <br /> <br />. <br />
