A database of environmental input parameters for River Invertebrate Prediction and Classification System (RIVPACS Model 44) implemented in a new version of the River Invertebrate Classification Tool (RICT).
The model predicts the invertebrate biological communities (species composition, abundance and value of biotic indices) at any site if its environmental quality was minimally impacted by people.
The database contains abiotic environmental parameters from geographical information systems for the river network of Great Britain on a 50 m grid based on the UK Centre for Ecology and Hydrology (CEH) Intelligent River Network. It includes the start and end location of the river segment on the Intelligent River Network on a 50m grid so that users can identify the river segment for which they want data.
The data is delivered to users from an online GIS system that allows them to select a location by Ordnance Survey grid reference, select an area and extract data for a 50m² grid, plus a larger polygon covering the 50m grids around the one selected.
