QUality Evaluation and Simulation TOol for River systems (QUESTOR)

QUESTOR simulates water quality in rivers to understand changing water quality and ecosystem health under past and present conditions. It is used: (1) to predict how river water quality will respond to climate change; and (2) to predict how river water quality will respond to changing water management (eg increased abstraction or discharge; planting river-bank trees; or building a flood relief channel).
