Spatial Analysis & Large Datasets

Over the past two decades, I’ve provided GIS and spatial analysis for a wide variety of projects including but not limited to support for groundwater modeling, environmental monitoring, and water resource planning projects. My work has focused on developing and managing complex spatial datasets—including land use, irrigation, stakeholder, and hydrologic data—to support groundwater basin modeling, watershed analysis, and engineering design.   

I’ve also conducted watershed delineation, bedrock depth analysis, and geologic interpretation to support groundwater storage evaluations across multiple modeling iterations. In addition to modeling support, I’ve helped maintain monitoring well and habitat datasets, supported field data collection, and contributed to the development of a digital inventory of monitoring sites with real-time reporting for resource management and early warning systems.

For water planning and infrastructure projects across the American West, I led GIS analysis that supported conceptual irrigation systems, water conveyance networks, inundation impact analysis, and litigation. My work included processing LiDAR data from raw LAS files into DEMs and contour datasets for engineering design, maintaining utility and hydrologic databases, and producing maps, visualizations, and Google Earth fly-over presentations to communicate design concepts to stakeholders.

As part of my support of groundwater and surface water modeling, I’ve processed geologic layering, recharge, and water use datasets and compiled long-term time series (600+ months) of precipitation, recharge, runoff, and evapotranspiration using bulk geoprocessing workflows to prepare model inputs.  Setting up and repeating workflows to make the monthly historical USGS Basin Characteristics Model data available to aide in model calibrations has been a key spatial analysis tool for our team.
