Automating drainage direction and physiographic inputs to the CEQUEAU hydrological model: Sensitivity testing on the lower Saint John River watershed, Canada

Abstract

© IWA Publishing 2017. CEQUEAU is a process-based hydrological model capable of simulating river flows and temperatures. Despite an active user base, no facility yet exists for the automatic assembly and input of watershed data required for flow simulations. CEQUEAU can therefore be time-consuming to implement, particularly on large (≥104 km2) watersheds. We detail a new MATLAB toolbox designed to remove this key limitation by automatically computing CEQUEAU's key drainage direction and physiographic inputs from geographic information system (GIS) data. With the toolbox, model implementation can now be achieved extremely quickly (
