Pilings have to be deep plenty of to resist wave and wind forces even though scour occurs. Columns may not be constructed on shallow foundations subject to undermining by nearby scour and erosion.
With this remaining the situation, you should not assume a WEAP prediction applying "set up time = 168 several hours" to correlate with the onsite noticed problems linked with EOID, or "setup time = 0 hours." Since this time variable is usually manipulated, it is usually recommended to complete various WEAPs involved with EOID (t=0 hrs) and also other time increments pertinent to the specific challenge wants.
