Computing river flows,
bringing technology to the field.

RiverLink is the core developer of iRIC, the river simulation software. Building on that, we offer AI adoption & coaching, numerical & geospatial analysis, programming and system development.

MISSION

Broadening the understanding and use of river simulation through iRIC

Drawing on our experience in every part of iRIC, from design and development to operation, we turn technology born in research into tools that work in river management and disaster prevention.

We value linking people with people, people with technology, and practice with research.

iRIC

Running iRIC day to day

iRIC is a free river-simulation platform that lets anyone use models developed by researchers through a common interface. Together with iRIC-UC and the iRIC research group, RiverLink handles the practical work of iRIC: development, web operations and training.
