With the raise of global concerns about climate changes and pollution in general, water monitoring became a major topic of interest in geospatial applications. There are a significant number of parameters that need to be monitored in a watershed, and varieties of sensors are used for this purpose. In modern sensor networks, sensors are not just simple data collectors, but also actuators that need complex programming. This paper presents a monitoring system for water parameters, based on a wireless sensors network (WSN) and the process of measuring several water quality parameters, aiming to detect pollutants. The experimental results, obtained using the Cyberwater platform for monitoring pollution on rivers, confirm the quality of the approach.
