该模型的核心为深度积分理论(浅水方程)，用户可轻松指定单个/多个泥石流启动区和侵蚀铲刮区开展数值仿真。根据案例与工况需求，用户可采用块体(block release，整体失稳)和水力(hydrograph release, 渐进失稳)两种方式启动泥石流。该模型基于单层深度积分理论，将泥石流视作均值等效流体，采用双参数Voellmy流变模型控制泥石流运动速度和致灾范围。

目前，团队正协同瑞士RAMMS AG团队Perry Bartelt教授携手开发RAMMS::Two-phase Debris flow模型。基于双层多相流和深度积分理论分析泥石流内部固-液作用，可模拟固相泥石流碎屑堆积后，饱水泥流远程致灾。即将上线，敬请期待。
