Influence of Sediment Disturbance
Since the year 2000, eastern Louisiana, coastal Mississippi, Alabama, and the western Florida panhandle have been affected by 28 tropical storms, seven of which were hurricanes. These tropical cyclones have significantly altered normal coastal processes and characteristics in the Gulf region through sediment disturbance. In fact, tropical storm-induced sediment disturbance is a factor in four of the five Gulf of Mexico Alliance (GOMA) priority issues:
• water quality for beaches and shellfish beds,
• wetland and coastal conservation restoration,
• characterization of Gulf habitats,
• and reduction of nutrient inputs to coastal systems. |
