HYDROLOGIC CALCULATIONS Clause Samples
HYDROLOGIC CALCULATIONS. The Engineer shall use the TxDOT Hydraulic Design Manual to prepare and submit the work under this task. The hydrology calculations must have the following: • Hydrological Method used • Drainage Area ID to corresponding culvert or inlet number • Size of Drainage Area • Cover of existing (i.e. include percentage of each cover to arrive at C, or CN) • Design Frequency based on the functional classification, type of roadway, and any other information noted on the Hydraulic Manual, Roadway Design Manual, or any other TxDOT literature and guidelines. Include the intensity and/or Precipitation for 24-hr rainfall. • Time of concentration (i.e. sheet flow, overland flow, & channel flow). • Intensity calculations for the design frequency and 1% AEP • Runoff calculations for the design frequency and 1% AEP DocuSign Envelope ID: D0894D65-6FF6-4E21-BE5E-BEEA53479086
