Water Seepage Meter

The seepage meter is installed into sediments of a body of water by inserting a PVC pipe into the sediment bottom, while ensuring the top of the tube is above the water’s surface. After allowing the system to equilibrate, the meter is activated.  A servo motor regulates the water level, and the device records base measurements. A linear position sensor determines if water is leaching out of the groundwater aquifer into the body of water, or if water is recharging from surface water into the groundwater aquifer.  A data logger measures the charge/recharge curve and sends information remotely for analyses of the data.  The measurements determine seepage rates and hydraulic conductivity of the sediments.
