Monitoring Network of the Coastal Aquifer in Northwest of the State of Yucatán (RNYW)

Responsable: Dr. Paulo Salles

Description

This project consists in the design and implementation of a monitoring network of the coastal aquifer in the northwest of Yucatán (RNWY). The goals are mainly to monitor aquifer water table, the position and evolution of saline interface and aquifer-sea interaction.

The first stage of the project includes defining a transect, perpendicular to the coast, with 4 monitoring points (wells) between Hunucmá and Sisal.  Each monitoring point has a pressure, temperature and electrical conductivity loggers (ONSET HOBO), sampling every 30 minutes (48 daily data points) during 24-48 months (more if possible), allowing the observation of daily and seasonal phenomena and processes in the aquifer and saline interface. Pressure loggers are installed 2 meter below mean water table level and electrical conductivity loggers are installed near the mixing saline interface zone (halocline).

Other monitoring points are included, using stations of the existing CONAGUA (National Water Commission) well network, in particular stations in Progreso, Chuburná, Sisal and Celestún.

The network is integrated by 11 wells:
   
     |     P1         |     Celestún          
     |     P2         |     Chunchucmil          
     |     P3         |     Amaris II          
     |     P4         |     Nohuayun          
     |     P5         |     Sisal          
     |     P6         |     Tamachen          
     |     P7a       |     UAY Sisak          
     |     P7b       |     Estanques Pescis          
     |     P8         |     Granja Crío          
     |     P9         |     Torre de Flujos          
     |     OBS      |     Observatorio
