Monitoring Overland Flow
Overland flow of water over the surface of soil can be accurately monitored with the addition of an Overland Flow Adapter that holds the unit with the top moisture zone above the surface. This zone is then calibrated for water, instead of soil, to an accuracy of 2mm.
If you know when water flows over the surface, you know when flooding begins.
Monitoring Water Table Levels in a Dipwell
The water table level is the most important factor in peat regeneration and also for sequestering carbon in peat. The Dipwell Adapter creates a secure mounting to the dipwell, and instead of returning 4 separate moisture zones, the data is calculated to estimate the water level in the dipwell, to an accuracy of 2mm.
As this data is returned in real-time, there is no need to send people into the field to take manual readings, which saves both effort and money.
Ground Movement Detection with Built In Accelerometer
Monitoring the state of a field that drains toward a railway or highway embankment provides early indications of potential problems. If the entire field is saturated, then any additional rainfall is headed toward the embankment increasing the risk of landslide. The unit’s built in accelerometer knows when ground movement has actually occurred.
The onboard accelerometer is sensitive to 0.25 degrees in any axis. An alert can be set to be sent immediately upon detected ground movement.
Data from the monitors in the embankment can highlight sections that require a site visit for deeper analysis. Soil saturation data along with temperature data showing freeze/thaw cycles can point to a slope at risk. An alert from the unit that shows actual ground movement means the risk of landslide is high.
Dales Land Net Rain Gauge
Having real time rainfall data available to compare with the changes in soil moisture levels is invaluable, as shown in the dashboard screenshot below.
We offer the DLN Rain Gauge unit with the same data connectivity options available for the DLN Soil Monitor.
Data Availability
We provide the data to you on a dashboard, or you can access the data directly using a web API.
Additionally, alerts can be set to notify when moisture or temperature reading cross a user-defined threshold. Alerts can also be set to warn of low battery levels, so that the unit can be serviced before it shuts down.
This screenshot from the dashboard shows the 4 zones of soil moisture data graphed against rainfall data (in grey), which is provided by the optional Rain Gauge unit:
