Mapeamento ambiental da bacia hidrográfica da Lagoa Imboacica: subsídio para construção de planos de bacia

Abstract

In the present work the map of occupation and use of land in Imboacica Lagoon hydrographic basin is presented. With the aid of this product, circularity and water quality indexes were calculated, based in: (i) the area/perimeter ratio of forest fragments; and (ii) water pH, turbidity, temperature, total solids, ammoniacal nitrogen, total phosphorus, biochemical oxygen demand, dissolved oxygen, total and fecal coliforms. The water quality was thus verifi ed, giving support to classification according to its preponderant usages, which is necessary to adequate water resources management.
