Contract for the Supply of Hydroacoustic River Flow Instrumentation

The Authority is seeking to establish a two-year call-off framework with an optional one year extension for the supply of hydroacoustic instrumentation, associated software, and supporting services to enable accurate measurement of river discharge. Accurate river-flow data is critical to the Authorities’ ability to manage water resources, understand changing river conditions, support flood forecasting, and respond effectively to incidents. The framework will cover the supply and, where required, installation support of: - Lot 1 - Mobile boat or tether‑mounted velocity profilers - Lot 2 - Handheld wading measurement systems - Lot 3 - Short‑range fixed‑deployment velocity instruments - Lot 4 - Long‑range fixed‑deployment velocity instruments
