Supporting files for a Langrangian particle tracking model evaluation of sediment exposure and burial for freshwater mussels

This project contains field data and supporting files for a Lagrangian particle tracking (LPT) model at a representative reach on the Osage River, Missouri. Field datasets include a topobathymetric digital elevation model (DEM) for a 5-km reach of the Osage River, water surface elevation profiles, and velocity data collected with acoustic Doppler current profiler (ADCP). Channel topography was generated from data collected by USGS staff from the Columbia Environmental Research Center during single beam sonar surveys of the channel bed and high-resolution Real Time Kinematic Global Navigation Satellite Systems for positioning. Field data was used to generate and validate a Lagrangian Particle Tracking model to evaluate the risk of sediment exposure and burial to freshwater mussel communities.

本项目包含用于密苏里州欧塞奇河（Osage River）典型河段的拉格朗日粒子追踪（Lagrangian Particle Tracking, LPT）模型的野外观测数据与配套文件。野外数据集涵盖欧塞奇河5公里河段的地形水深数字高程模型（Digital Elevation Model, DEM）、水面高程剖面，以及采用声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）采集的流速数据。河道地形数据由美国地质调查局（U.S. Geological Survey, USGS）哥伦比亚环境研究中心的工作人员，通过单波束声呐对河道床体开展勘测，并借助高分辨率实时动态全球导航卫星系统进行定位所采集的数据生成。所获取的野外数据被用于构建并验证拉格朗日粒子追踪模型，以评估沉积物暴露与掩埋对淡水贻贝群落带来的风险。
