These BUTTONs enable YOU to over-ride a hydraulic friction slope or hydraulic element flow capacity estimated in BUTTON 5. This over-ride remains in effect unless removed or changed by YOU.
Reasons to over-ride a friction slope or hydraulic element flow capacity estimate include:
– Add additional flow capacity to a particular hydraulic element due
to supplemental calculations not included in the hydraulics models
– Reduce flow capacity estimates in order to increase future flood protection at a particular location due to increased safety needs
– Other reasons.
