This Major Research Instrumentation (MRI) Program award provides support for the acquisition of equipment to support research on the hydro and sediment dynamics of the lower reaches of the Buffalo River and within Lake Champlain in areas impacted by bi-directional flows. Specific equipment to be purchased includes: 1) multiple acoustic Doppler current profilers (ADCP), surface meteorologic (MET) sensor packages, bottom water temperature sensors and associated hardware to initially install five ADCP/MET observational systems along the reach of the lower Buffalo River; 2) a bathymetric profiling system; and 3) a laser diffraction based grain size analysis system. The acquisition of these instruments will support research on the physical processes that control sedimentation and bottom surface morphology (e.g., furrows) in the lower reaches of the Buffalo River, which due to lake wind-driven seiche effects exhibits hydrodynamic behavior analogous to estuarine dynamics. PIs from Buffalo State College and Middlebury College in Vermont will incorporate observational data into models for hydro and sedimentary bedform dynamics in the Buffalo River and Lake Champlain. The Buffalo River is heavily impacted by industrial effluents and bottom sediments sequester a large variety of deleterious inorganic and organic compounds. Advances in understanding of the hydrodynamic forcing of sedimentary deposition and transport have ramifications for remediation efforts. Buffalo State College (BSC) is a Hispanic serving undergraduate institution, and Middlebury College is a liberal arts institution in Vermont with active undergraduate research programs.

该重大研究仪器 (MRI) 计划奖项为购买设备提供支持，以支持对布法罗河下游和尚普兰湖内受双向流影响的区域的水文和沉积物动力学研究。 需要购买的具体设备包括： 1) 多个声学多普勒海流剖面仪 (ADCP)、表面气象 (MET) 传感器包、底层水温传感器和相关硬件，以便在布法罗河下游河段初步安装 5 个 ADCP/MET 观测系统； 2) 测深剖面系统； 3) 基于激光衍射的晶粒尺寸分析系统。 这些仪器的获得将支持对控制布法罗河下游沉积和底面形态（例如沟渠）的物理过程的研究，由于湖泊风驱动的塞克效应，表现出类似于河口动力学的水动力行为。 佛蒙特州布法罗州立学院和米德尔伯里学院的 PI 将把观测数据纳入布法罗河和尚普兰湖水文和沉积岩床动态模型中。 布法罗河受到工业废水的严重影响，底部沉积物隔离了大量有害的无机和有机化合物。 对沉积物沉积和迁移的水动力强迫的理解的进展对修复工作产生了影响。 布法罗州立学院 (BSC) 是一所西班牙裔本科院校，米德尔伯里学院是佛蒙特州的一所文科院校，拥有活跃的本科研究项目。
