Aims:The main aim of this research is to progress characterisation of fundamental behaviours of debris flows identified in the field to assess for critical design cases for structural barriers with respect to fluid rheological properties and particle dispersity. This seeks to enhance numerical simulation ofevents and mitigation structure flow interactions for improved protection.Objectives:1. To determine small-flume scaling requirements to improve physical modelling application to field events and large-scale experiments.2. To produce a data-based understanding of flow mobility responses to fluid viscosity, clay minerology, and implications on segregation.3. To compare numerical model outputs to physical data of unobstructed flow to establish and reduce limitations.4. To develop a preliminary numerical model based on physical testing of flow response to slit barriers for appropriate application and design refinement in industry

目的：本研究的主要目的是推进现场确定的泥石流基本行为的表征，以评估结构屏障在流体流变特性和颗粒分散性方面的关键设计案例。这旨在加强事件的数值模拟并减轻结构流相互作用，以改善保护。目标：1。确定小水槽缩放要求，以改进物理建模在现场事件和大规模实验中的应用。2．基于数据了解流动性对流体粘度、粘土矿物学的响应以及对离析的影响。3．将数值模型输出与无阻碍流动的物理数据进行比较，以确定并减少限制。4．开发基于对狭缝屏障的流动响应的物理测试的初步数值模型，以便在工业中适当应用和设计改进
