Hydrodynamic & Sediment Transport Analysis     Figure 6. Results of hydrodynamic and sediment transport process analysis.   (a) Wave climate for the mouth of Narragansett Bay, wave height vs. cumulative    probability greater than,   (b) Wave climate of the mouth of Narragansett Bay, wave period vs. wave height,   (c) Tidal currents (cm/s) at I m above the bed for the sand (TVs 1) and mud (TVm 1)    experimental sites,   (d) Probability of sediment erosion at the sand and mud experimental sites based on the    critical erosion velocities (cm/s), and maximum bottom velocities (cni/s) vs. the    cumulative probability greater than.
