Feedback between Basin Morphology and Sediment Transport at Tidal Inlets: Implications for Channel Shoaling

Increasing societal pressures (e.g., population growth and urbanization) are driving land use change practices in coastal areas that could potentially alter the hydrodynamics sediment transport patterns near inlets ways might exacerbate existing shoaling conditions. To investigate potential impact of development, a numerical model is used to predict long-term evolution an idealized lagoonal-type barrier island inlet under five different morphological conditions transitioned from net import export. The simulations were designed address effect inter-tidal placement reclamation on resulting deposition/erosion patterns. Estuaries deeper devoid extensive tidal flats tended promote had greater propensity channel shoaling. Simulations characteristic showed export, yet likelihood was increased because some material eroded deposited channels as opposed being carried out throat. Alternatively, it found regions which intertidal area restricted elevations higher frame, also produced loss zone bypass sections, reducing
