Use of Geospatial and multivariate statistical analysis in support of water quality monitoring of hydroelectric reservoirs

Abstract

The size and spatial heterogeneity of reservoirs depend on their morphometry, retention time, thermal stratification, season, and geographical location (Tundisi et al., 2012). The longitudinal distribution of biogeochemical variables depends on the extent of individual zones (Roberto et al., 2009) and due to nutrient inputs and optimal light availability, the maximum development of chlorophyll is located in the transitional zone (Wetzel, 2001).  Broad, deep, lakelike basin  Little flow  Relatively clear water  Organic matter > autochthonous  More oligotrophic
