For instance, if the natural cross section had twice as much conveyance in the left overbank as in the right overbank, a 10 percent conveyance reduction value would reduce 6.7 percent from the left overbank and 3.3 percent from the right overbank. 02-15-2019 Abandoned Manhole and Pipe (DWG) 02-15-2019 Alternate and Regular Drop Stack (DWG). Equal conveyance reduction is the default.Īn alternate scheme to equal conveyance reduction is conveyance reduction in proportion to the distribution of natural overbank conveyance. Take a look at the Conveyance Details DWG Documents. A value of 10 percent for the second profile would indicate that 10 percent of the conveyance based on the natural profile (first profile) will be eliminated 5 percent from each overbank. The percentage of reduction in conveyance can be changed for any cross section. With rising demand and recognition of the variety of cases attended by emergency ambulance crews, services have been considering alternative ways of providing non-urgent care. Subsequent profiles (profiles 2-15) of a multiple profile run may be utilized for Method 3 encroachments. An example of encroachment method 3 is shown in the figure below.Įncroachment Method 3 requires that the first profile (of a multiple profile run) must be a natural (un-encroached) profile. If the percent reduction in cross section conveyance cannot be accommodated by both overbank areas combined, the encroachment stations are made equal to the stations of left and right channel banks (or the offset stations, if specified). If one half of the conveyance exceeds either overbank conveyance, the program will attempt to make up the difference on the other side. The computed encroachments cannot infringe on the main channel or any user specified encroachment offsets. One-half of the conveyance is eliminated on each side of the cross section (if possible). The Zone 7 Water Agency's Board of Directors is set to consider continuing to fund and participate in the planning phase for the Delta Conveyance Project at its regular board meeting on Wednesday, following an initial approval to participate for two years in late 2020. Method 3 calculates encroachment stations for a specified percent reduction in the conveyance (%K Reduction) of the natural profile for each cross section.
