The article presents a methodology for the delimitation of the coastal transition zone (CTZ) and the identification
of zones with distinct soil properties in the Gulf of Guayaquil (GG), Ecuador. The Gulf was chosen as study area
for its urban, economic and ecological potential, more in particular for its rich marine and agricultural resources,
and biodiversity. Soil physical and chemical methods, such as soil salinity indices, physical and chemical
parameters, coupled with multivariate analysis enabled the delimitation of the CTZ and the grouping of the
studied soil transets in three clusters with distinct properties, located in the GG from the limit of the mangrove
swamp. Whereas the average conductance in the swamp area is around 27.17 mS cm-1, inland to the isoline
called the coastal transit zone soil salinity on average is 4 mS cm-1. The coastal transition zone has an average
width of 4.2 km, which can be characterized by three clusters. Clusters 1 and 2 show similarities in their physical
and chemical soil parameters, clearly different from the soil properties of cluster 3. The characteristics of each
cluster is related to its location within the study area. [-]
