Background Coastal estuaries locate on where the rivers meet the sea with many favorable physical conditions for human to settle and develop. Large urbans with concentrated residental areas economic zones national defense and security regions are gradually expanded on those areas to serve the people such as industrial sites administrative area civil works airports harbors services trades etc. The topology of the coastal estuaries on Vietnam Northern Central coast has formed and developed under the interplay of numerous external internal and artificial dynamical processes furthermore these are also stage for complex river-ocean interactions. The consequence of those processes has made coastal estuaries prograde toward the sea since Pleistocene epoch to the modern day formed identical type of landform from shoals sandbars sand barriers to deltas. Coastal estuaries are normally favourable places for socio-economic developments but they are also intimidated as .
