Our case studies highlight learning and innovations from ResilienTogether. They share new approaches and techniques that can be replicated by other schemes and organisations across the country. They also demonstrate how practical innovative actions can work to improve resilience to flooding.
ResilienTogether is working to connect the public and stakeholders with the Pix Brook and their local environment.
ResilienTogether is creating a Smart Catchment, through innovative technologies and techniques, to reduce flood risk to people and places, enhance the water environment in the Pix Brook catchment and improve community resilience in the face of climate change.
The project is achieving this through a close-knit partnership that collaborate to deliver six inter-related work packages. This case study comes from WP1 Flow Monitoring which aims to enhance the flow monitoring and telemetry network to improve understanding of flows within the catchment and establish near real-time flow monitoring.
Read more about our Stilling Tube Post, its benefits and why this innovation is important: Stilling Tube Post: Case Study
RDN have designed a stainless steel adapter and stilling tube post. The level gauge is slotted into the Stilling Tube Post 154mm ID Ring which has an end plate beneath. This is fixed onto a 600mm long Stilling Tube Post Internal Spear Plate that is embedded into the river bed .
When there is no flow, a trigger sensor acknowledges this and reduces data upload frequency. A micro power sensor then detects when flow picks back up to reactivate the default monitoring frequency. This save battery life and extends the life of the gauge.
This new and innovative design is installed on the Pix Brook tributary that joins at Stotfold. It overcomes the barriers of fixed gauges in low flow environments by creating a flexible and efficient approach to installation. These innovations in redeployment and energy saving provide the maximum benefit to river level monitoring for the least cost.
Through the design and installation process, learning has been gained on level monitoring costs, product specification and performance that may be of interest to organisations seeking to develop their own monitoring networks.
Easy installation
The Stilling Tube Post allows for easy installation by eliminating the need for concrete and overcoming the barriers of watery environments.
Mobile gauging
As the post is embedded in the ground with no use of concrete, the gauge is mobile. This allows for re-deployment and movement to other locations.
Free standing gauging
Gauges usually need to be installed on existing structures such as bridges or gates. This post means the gauge can be free standing, unlocking the ability to gauge in many more locations.
