Modeling Sand Accumulation of Restored Coastal Dunes

NOAA benchmark used for survey analysis at Isla Blanca Beach Park, South Padre Island, Texas, USA (Alayibo, 2022)
Mitigation areas where dunes were restored, and current data collection
Innovative vegetation pattern alternating the plant species in MA 6 (Gonzalez, 2019)
Restoration in MA-2 and MA-6
Restored in August 2019
2 to 3 nodes of vegetation
1.5 ft spacing on dune toe, 3 ft spacing on back dunes
Undulating dune design with fiber mat on front dune
Coconut fiber mat installation in MA–2 (Patel, 2020)
Increases the stability of the dunes
Installed up to 2 ft. under the sand
Irrigation is added after installation, prior to planting
Planting Pattern for MA-4 & MA-5 (Patel, 2020)
Restored in August 2020, but had limitations due to the pandemic
Rows are 4 ft. apart along the toe and 9 ft. apart for the remainder
There are 6-8 nodes of vegetation that are sustained only by irrigation lines
There are no coconut fiber mats on the toe of the dune
MA-6 Dune growth with matured native vegetation a) planting in August 2019, and b) maintenance in September 2019 (Mohammed, 2020)
