Considering interviewee's perceptions, the most reported category
was “changes in the spatial configuration of the Bay and its
coastline” (Table 4). As perceived in aerial photographs of the area
(Fig. 3), successive landfills related to harbor expansion were
installed in the bay, which changed its configuration and led to a
reduction of its total area. The second most cited change (“changes
in the hydrodynamic and sedimentary characteristics of the bay”) is
related to the first one, since the construction of successive landfill
areas reduced the magnitude of hydrodynamic forces (Villamarin,
2014), which corroborates with interviewees perceptions.
