The general objective of this study was to develop a software based on a water quality indicator (WQI) system considering chemical, physical-chemical, and biological parameters evaluated in four seasonal periods in Samuel dam. A web interface may facilitate the use of monitoring results routinely, which allows periodic insertion of previously selected water quality parameters results, to finally provide a simple and direct way to evaluate the water quality.
Maintaining the water quality involves long-term monitoring programs established by the requirements of Brazilian legislation. The quality of the water in the Amazon's reservoirs is of fundamental importance for natural ecosystems, biota, and for the region's population.
