Towards reliability-management for debris flow risk assessment

Recent progress in data-integrated simulation methods excelled our understanding of debris flows including triggering mechanisms and dynamic run-out behavior. Research groups geohazard practitioners worldwide successfully integrate advanced simulations into workflows for hazard mapping. However, many challenges remain predictively applying such tools accepted decision support. One reason is lack a systematic approach to managing the simulations’ reliability. In this contribution, we present results on an investigation which extent choice data used calibration influences simulation’s We start with introducing building blocks modular extendible flow toolchain developed by group. Next, introduce reliability as one quality measure holistic discuss how it can be assessed. Based synthetic example, then show different types observed data, impact area, deposit volume or localized velocity measurements impacts subsequent forward posterior probability distribution, hence conclude discussing linking type, scope resolution could offer novel pathway towards management risk assessment.
