<br />RECOMMENDATIONS <br /> <br />The following recommendations are included for consideration <br />in reducing potential flood damages: <br />1. Carry out periodic maintenance of bridges and culverts to <br />preserve hydraulic capacity. <br />2. Implement design recommendations included in the "Drainage <br />Master Plan for The City of Cripple Creek". <br />3. Do detailed study of need for flood proofing <br />around facilities in the flood plain or consider <br />flood insurance. <br />4. Information and education programs on flood hazards <br />should be made available to the public. <br />5. The main channels should be maintained to preserve <br />a balance between native vegetation, conveyance <br />capacity, channel stability, and provide wildlife <br />habitat. <br /> <br />" <br /> <br />20 <br /> <br />GLOSSARY OF TERMS <br /> <br />Channel - A natural or artificial water course of <br />perceptible extent with definite banks to confine <br />and conduct continuously or periodically flowing <br />water. Channel flow is that water which is flowing <br />within the limits of the defined channel. <br />Flood - Water from a river, stream, water course, lake <br />or other body of standing water, that temporarily <br />overflows the boundaries within which it is <br />ordinarily confined. <br />Flood Crest - The maximum stage or elevation reached <br />by the waters of a flood at a given location. <br />Flood Frequency - A means of expressing the probability <br />of flood occurrences as determined from statistical <br />analysis of representative streamflow or rainfall <br />and runoff records. The frequency of a particular <br />stage or discharge is usually expressed as occurring <br />once in a specified number of years. The 10-, 50-, 100-, <br />and SOO-year f~equency floods have an average frequency <br />of occurrence Ln the order of once in the number of <br />years indicated. <br />Flood Hazard Areas - Areas susceptible to flOod damage. <br />Flood Peak - The highest stage or discharge attained <br />during a flood event; also referred to as peak stage <br />or peak discharge. <br />Flood p~ain - The relatively flat or lowland area adjoining <br />a r~ver, stream, watercourse, lake, or other body of <br />water whiCh has been or may be covered temporarily <br />by flood water. For administrative purposes the flood <br />plain may be defined as the area that would be <br />inundated by the lOO-year flood. <br />Left or Right stream Bank - The left or right bank of the <br />stream looking downstream. <br />PerChed Channel Flow - A condition where the flow elevation <br />in the outer portions of the flood plain is higher than <br />the flow elevation in the main channel. This condition <br />occurs when a secondary channel receives inflow <br />from some location upstream and maintains a flatter <br />slope than the main channel. <br />R~~ch - A hydraulic engineering term used to describe <br />longitudinal segments of a stream or river. <br />Runoff - That part of precipitation, as well as any other <br />flow contributions, which appears in surface streams <br />of either perennial or intermittent form. <br />Stream - Any natural channel or depression through whiCh <br />water flows whether continuously, or intermittently <br />including modification of the natural channel or ' <br />depression. <br />
