Estimating BMP Treatment Train Benefits with Lidar Data.

As higher resolution geospatial data become available, new geoprocessing techniques are being developed to better estimate physical processes occurring throughout the landscape. This includes estimating pollutant loading to surface water resources and determining suitable locations for best management and conservation practices. However, estimating the load reduction of multiple conservation practices (i.e. treatment trains) that provide treatment of water in sequence often proves challenging.  This presentation will outline a novel technique that was developed to measure water quality improvements from treatment trains by utilizing the high resolution (3 meter) light detection and ranging (LiDAR) data.  The results provide valuable information for practitioners to assist in resource management, implementation planning, and overall budgeting.
