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.

该主要研究仪器（MRI）项目奖为购置设备提供支持，以支持布法罗河下游和尚普兰湖受双向水流影响地区的水力和泥沙动力学研究。采购的具体设备包括：1)多个声学多普勒电流剖面仪（ADCP）、地面气象（MET）传感器包、底水温传感器和相关硬件，初步沿布法罗河下游安装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布法罗河下游控制沉积和底表面形态（如沟槽）的物理过程的研究，由于湖风驱动的淤积效应，布法罗河下游表现出类似于河口动力学的流体动力学行为。来自布法罗州立学院和佛蒙特州米德尔伯里学院的pi将把观测数据纳入布法罗河和尚普兰湖的水文和沉积河床动力学模型。布法罗河受到工业废水的严重影响，河底沉积物隔离了大量有害的无机和有机化合物。对沉积沉积和搬运的水动力强迫的理解的进展对修复工作有影响。布法罗州立学院（BSC）是一所西班牙裔的本科院校，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。
