Environmental monitoring of microtidal estuaries: Case Study Jamapa River

S Standing out the characteristics of salt wedge estuaries, a specific monitoring plan for the Jamapa River was conceived that allowed to establish the salt stratification-level due to the yearly variation of river discharge in locations along the estuary. Stratification is a limiting factor for bottom and surface water interchange, promoting nutrient, pollutants and organic matter accumulation resulting in a possible algal bloom or depletion of dissolved oxygen. Stratification level was determined through the global salinity index Sp.
