Post‐fire debris flows and tailing impoundment failures destroy lives and property. These geologic hazards – and other similar processes – fall on a continuum between classic Newtonian flood analyses and geotechnical stability analyses. The US Army Corps of Engineers (USACE) is developing a non‐Newtonian library (DebrisLib) that includes a suite of rheological and clastic approaches to hyper‐concentrated, mudflow and debris flow dynamics. The Hydrologic Engineering Center (HEC) has implemented these non‐Newtonian methods into the widely used, public‐domain open‐channel hydraulics and morphodynamic software, HEC‐RAS (river analysis system). This work presents part of the verification and validation of these non‐Newtonian approaches, applying several rheological equations to published laboratory results high‐concentration flume experiments.

将单相，非牛顿方法与实验结果进行比较：验证HEC-RAS中的水垢垢和泥石流

火灾后的泥石流和尾矿库破坏破坏了生命和财产。这些地质灾害和其他类似过程属于经典的牛顿洪水分析和岩土稳定性分析之间的连续体。美国陆军工程兵团（USACE）正在开发一个非牛顿图书馆（DebrisLib），其中包括一套流变学和碎屑方法，用于处理超浓缩，泥石流和泥石流动力学。水文工程中心（HEC）已将这些非牛顿方法应用于广泛使用的公共领域明渠水力学和形态动力学软件HEC-RAS（河流分析系统）中。这项工作提出了对这些非牛顿方法的验证和确认，将几个流变方程应用于已发表的实验室结果高浓度水槽实验。
