Salt wedge monitoring
Monitor in real time the position and evolution of the salt wedge
With SMD Intrusion, you can monitor saltwater intrusion for sustainable management of coastal aquifers and better protection of water resources.
53 sites already surveyed, instrumented and monitored in mainland France, French overseas departments and territories and abroad.
Salt water: monitoring for better anticipation
Climate change, rising sea levels, falling piezometric levels caused by excessive pumping, droughts… There are many situations that can lead to saltwater intrusion.
With SMD intrusion, you can assess the vulnerability of coastal aquifers to saltwater intrusion, monitor their condition in real time and control the phenomenon to preserve freshwater reserves.
Manage your coastal water resources effectively
Measure the resistivity of the medium by injecting an electric current between two electrodes at different depths. Electrical methods are the most effective for measuring the interface between fresh and salt water.
Get the vertical resolution you need to detect fine variations in water conductivity and pinpoint the interface between fresh and salt water.
Avoid any measurement errors and guarantee the durability of your monitoring system thanks to the absence of electronics in the borehole (only at the head of the structure). What’s more, benefit from reliable data that is not affected by the mixing of water in the piezometer thanks to measurements taken outside.
View and interpret data in real time in the EMI software to anticipate and optimise the management of your water resources. Receive automatic alerts when salt water levels rise.

EMI, the water hypervision solution
all-in-one
Manage, view and interpret environmental data in real time and be alerted in the event of a crisis.
Based on real-time data, EMI enables you to anticipate and optimise the management of your water resources.
They use SMD Intrusion to monitor their salt bevels
SYMCRAU
“Data is accessible in real time thanks to the EMI platform”.
“SYMCRAU worked with ImaGeau to equip a sentinel monitoring piezometer with the SMD system. The instrumentation was implemented by ImaGeau teams in October 2019, and the data can be accessed in real time using the EMI platform. By regularly displaying the data and setting alert thresholds, we can obtain precise information on the state of salinisation of the aquifer in all its dimensions. The ultimate aim is to adapt, if necessary, the management measures and/or operating conditions of a wellfield.
