Diseño e implementación de sistema in situ para medición de turbidez en el agua

Abstract

Climate change has prompted various research efforts seeking to curb mitigation of its impact. The oceans and all the life forms that inhabit there are one of the most affected agents, in this case, coral reefs play an extremely important role in the marine environment. There is a coral reef located in the Bay of Cartagena: the Varadero reef, which has aroused the interest of biologists for its great adaptive capacity to adverse environmental conditions, such as: the large amount of debris, pollution and numerous amount of suspended sediment. These factors alter the turbidity in the water; a high turbidity reduces the amount of light that reaches the corals, affecting their development. The turbidity variable is then of great importance in this study, which justifies this project where the design and implementation of a device whose purpose is to measure turbidity in different bodies of water and at different depths is presented. For the development of the device, logical steps were defined to achieve its resolution, based on some objectives proposed prior to an investigation: Bases were laid by means of a theoretical framework and the background check. A mechanical and electronic design was defined; Carrying out an analysis of alternatives that defined each of the components to be used. Next, the implementation of each subdivision was carried out, thus obtaining the prototype that was calibrated using turbidity standards, validated with laboratory turbidimeters and tested in real environments; leaving as a result the system for the measurement of turbidity in situ.
