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.

这项主要的研究仪器（MRI）计划奖为获得设备的获取提供了支持，以支持对布法罗河下游和尚普兰湖内的水力和沉积物动态的研究，并受到双向流动影响的地区。 要购买的特定设备包括：1）多个声学多普勒电流剖面（ADCP），表面气象（MET）传感器软件包，底部水温传感器和相关硬件，以最初沿着下部布法罗河的触及到最初安装五个ADCP/MET观察系统； 2）一个测深的分析系统； 3）基于激光衍射的晶粒尺寸分析系统。 这些仪器的获取将支持对控制沉积和底部表面形态（例如，沟（例如，犁沟）的物理过程的研究，布法罗河的下到达，这是由于湖泊风驱动的seiche效应表现出类似的流体动力学行为。 来自佛蒙特州布法罗州立大学和米德尔伯里学院的PI将将观察数据纳入布法罗河和尚普兰湖的水力和沉积床形动态模型中。 布法罗河受到工业废水和底部沉积物的严重影响，隔离了各种各样的无机和有机化合物。 理解沉积沉积和运输的流体动力强迫的进步在修复工作方面有很大的影响。 布法罗州立学院（BSC）是一家西班牙裔美国人的本科机构，米德尔伯里学院（Middlebury College）是佛蒙特州的一家文科机构，拥有活跃的本科研究计划。
