Hydraulic Design Manual:Time of Concentration

Anchor:#i1107984 Section 11:Time of Concentration. Time of concentration (t c) is the time required for an entire watershed to contribute to runoff at the point of interest for hydraulic design; this time is calculated as the time for runoff to flow from the most hydraulically remote point of the drainage area to the point under investigation. Mechanical performance of overlap connections with grout Oct 15, 2020 · To study the mechanical performances of a new kind of overlapping connection with grouted anchor reinforcements in embedded metal corrugated pipes, a total of 24 groups of 72 specimens were prepared and tested. The overlap connection performance of grouting anchor reinforcements in embedded metal corrugated pipes was studied by bi-directional tension test.
