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.
Embankment Ground Movement Detection with Built-in Accelerometer
A shallow landslide on an embankment can happen when the soil becomes too wet. If the monitoring data says the soil is nearly saturated, then a week of forecast rain may indicate that a slope is susceptible to 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 email can be automatically generated when a moisture level threshold is exceeded or when ground movement is detected.
Across time, the monitoring data begins to paint a picture of the characteristics of a slope and increases understanding of when to prioritise a site visit for deeper analysis.
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:
