profiles are above the minimum. An initial value of the 200-year
water surface elevation (29.03 ft, MBK, 2008) was used to assess the
levee elevation parameter, considering the lowest point of the reach
(Freeport station). The minimum elevation of the levee should be
this value plus the freeboard, which is 9.8 m. According to this
value, all the levees of the reach meet the minimum hydraulic top
of the levee criteria. In terms of the waterside slopes, about half of
the levees on the west and the east margin are below the minimum
criteria, whereas on the landside, 80% and 98% do not meet the minimum
slope on the east (urban) and west margins, respectively.
