520 a$aAn assessment of beach geomorphology and sediment grain size were done
at Cibuco Beach, Vega Baja Puerto Rico, from March 2011 to May 2011.
Subaerial beach (width and elevation) and sediment grain size changes were
evaluated and related with physical variables as river discharge and wave
height to identify the possible role of these variables causing geomorphic
changes in the site. Three stations were selected base on their unique physical
variables to collect beach profile measurements and beach sediment on a
monthly basis. Beach profile was measured in selected permanent beach
station. Sediment grain size was determined using sieving analysis. River
discharge and wave regime data were described using publishing data from
US Geological Survey (USGS) and Caribbean Coastal Ocean Observing
System (CariCoos). Evaluation of maps and remote sensing data were used to
describe additional variables related with human activities and other physical
variables. Results showed major beach geomorphic changes were found in less
protected coastal sites due to the lack of natural barriers. Coarser sediments
are mainly found in Station 1 and Station 2 with grain size ranges from 1
mm to 0.5 mm. Beach profile station 3 presented a more dynamic grain size
distribution through time, which varied from gravel to very fi ne sand (2 mm to
0.425 mm). River discharge and wave regime data showed, a possible relation
between high discharges peaks and low energy wave regime with deposition
of finer sediments in Station 3. Finer sediment grain size distribution may
be related to the occurrence of high discharge events at Cibuco River.
