LUCST: A novel toolkit for Land Use Land Cover change assessment in SWAT+ to support flood management decisions

Land Use Cover (LULC) change is widely recognised as one of the most important factors impacting hydrological response river basins. SWAT+, latest version Soil and Water Assessment Tool, has been used extensively to assess impacts LULC change. However, process making assessing such changes in SWAT+ often cumbersome non-intuitive, thereby reducing its usability amongst a wider pool applied users. We address this issue by developing user-friendly toolkit, Change SWAT + Toolkit (LUCST), that will: (1) allow end-user define various scenarios their study catchment, (2) run model with specified changes, (3) enable interactive visualisation different output variables. A good System Usability Score (79.8) positive feedback from end-users promises potential for adopting LUCST future studies. https://youtu.be/QygBidYr4cQ . • an open-source, locally hosted, JavaScript application SWAT+.
