Time of concentration definition

Time of concentration means the time it takes for runoff to travel from the hydraulically most distant point of the drainage area to the point of interest within a watershed.

Time of concentration means the time required for the point furthest from the outlet of the watershed to contribute to flow at the outlet of the watershed.

Time of concentration means the time it takes for flow to reach the drainage basin outlet from the hydraulically most remote point in the drainage basin.

Examples of Time of concentration in a sentence

• Time of concentration is an important variable in many hydrologic methods, including the Rational and Natural Resources Conservation Service (formerly SCS) procedures.

• The following lag times may be allowed: Table 6.4 Time of concentration shall be based upon an evaluation of the time of flow in accordance with Manning's velocity.

• The following are guidelines: tc - Time of concentration - where the time of concentration is less than 5 minutes, 5 minutes will be used for all calculations.

• Additional details are also available in the San Bernardino County Hydrology Manual in the following sections:  Runoff volume - Section J for drainage areas less than 10 acres or Section E for drainage areas greater than 10 acres;  Time of concentration - Section D.3 for drainage areas less than 640 acres or Section E for drainage areas greater than 640 acres;  Peak flowrate - Section D.1 for drainage areas less than 640 acres or Section E for drainage areas greater than 640 acres.

• Time of concentration (Tc) is the time for runoff to travel from the hydraulically most distant point of the watershed to the point where the hydrograph is to be calculated.

More Definitions of Time of concentration

Time of concentration means time required for water to flow from the most remote point of a drainage area, in a hydraulic sense, to the point of analysis.

Time of concentration means time required for a drop of water to travel from the most hydrologically remote point in the watershed to the point of collectionthe time period for the furthest runoff from the outlet of a watershed to contribute to flow at the watershed outlet.

Time of concentration means the time required for runoff to flow from the hydraulically most distant point in the watershed to the watershed outlet once the soil has become saturated and minor depressions have been filled.

Time of concentration means the time for surface runoff to travel from the farthest point in a watershed to the outlet point of the watershed. For purposes of calculations used to meet the requirements of this ordinance; the following roughness coefficients shall be used:

Time of concentration means the time needed for water to flow from the most remote point in a watershed to the point of interest within the watershed. It is a function of topography, geology and land use within the watershed and is computed by summing all the travel times for consecutive components of the drainage conveyance system.

Time of concentration means the time needed for water to flow from the most remote point in a watershed to the watershed outlet. It is a function of topography, geology and land use within the watershed.

Time of concentration means the time required for stormwater runoff from the remotest part of the drainage basin to reach the point being considered. Minimum time of concentration required for design of drainage facilities shall be 15 minutes.
