CITY OF LINO LAS Climatology Conveyance System Dead Storage Depression Storage Design Storm Detention Basin Eutrophication Freeboard Flood Evaluation Storm Flood Plain 10/24/94 Appendix B Definitions The meteorological study of the temperature, precipitation, and wind that characteristically prevail in a particular region. The series of swales, gutters, ditches, culverts, storm sewers, creeks, streams and rivers that carry water. That volume of water lying below the outlet elevation of a particular waterbody. That volume of water that collects in low points of streets, yards, fields, etc., without running off. The design storm (DS) gives the water surface elevation for an event of a given probability of recurrence. The DS provides a realistic estimate of water surface elevations based on rainfall amounts, durations, distributions, and soil conditions for a given recurrence interval. The DS is used to design the facility. Any areas that temporarily detains storm water runoff for the purpose of storm water management. The area does not have a normal surface water elevation, that is, it is dry during periods of low precipitation. The process by which a lake receives an increase of mineral and organic nutrient, thereby reducing the dissolved oxygen, producing an environment that favors plant over animal life. The difference between the design storm - water surface elevation and the minimum building elevation. The flood evaluation storm (FES) is defined as that storm used to estimate practical maximum water surface elevations for all possible rainfall amounts, durations, distributions, and soil conditions for a given recurrence interval. The area of inundation caused by flood waters. Local Water Management Plan SEH No. A- LINOL9402.00 Reference Document Page B - 1
