WebIrrigation is through a network of flow-splitters and underground emitters that divide and subdivide the flow, spreading it out in the landscape. Webbypass flow rate of 0.1 cfs will not usually cause erosion or hydroplaning problems. The PEO shall analyze the spread width of flow after the last inlet on a continuous run of curb until the curb ends or the curb enters into a sump. The spread width analysis shall end at the 50-year water surface elevation determined in the sag analysis.
