I am a hydrologist for the USGS – New Mexico Water Science Center and in charge of all technical watershed-modeling activities. I have developed data processing and analysis techniques and serve as the center's technical authority on all precipitation runoff modeling system (PRMS) and snow hydrology activities. I am currently developing and implementing novel characterizations of forest canopy as well as snow modeling tools in order to quantify the effects of canopy disturbance on snow water resources from a recently awarded competitive grant from the South Central Climate Science Center.

•Scripting / Coding is and has been an integral part of my work flow for over ten years. After I open my email each morning, I typically then open the command line window and start a blank matlab script. My scripting activities range from daily data analysis to dyanmically programmed interfaces and stand alone programs to process and analyze environmental data. I have several packages for novel LiDAR data manipulation, analysis and visualization available upon request. I coinisder myself an expert in Matlab, highly proficient in R, and have a base foundation in Python and Fortran as well as HTML and CSS.
• Deployment and Development of Meteorological Equipment
The recovery timing of burned watersheds, or the time the watershed takes to return to pre-fire peak flow state, is a function of many processes and can range from just a few years to decades. The watershed recovery continuum (the initialization, duration, rate and plenum) is based upon many interrelated aspects such as the portion of the watershed initially affected by fire, fire severity, storm duration, storm timing and storm intensity. However, recovery can be indirectly quantified by runoff efficiency, which is defined as the percent of precipitation that collects and creates runoff in a stream channel. Runoff efficiency is related to runoff travel time, and in general runoff travel time decreases as post-fire runoff efficiency increases following a wildfire compared to pre-fire values.
Stay tuned for an upcoming ISI joiurnal article which analyzes watershed response and recovery in a small SW US watershed.Wildifire, Watershed, Modeling, Recovery
I was responsible for the development of a Precipitation Runoff Modeling System (PRMS) created for a small southwestern US watershed to determine post-fire wildfire effects of the hydrologic system. I created and calibrated two models: one model for pre-fire conditions and one model for post-fire conditions. The post-fire model was able to accurately model post-fire watershed response primarily from the manipulation of 5 manually calibrated parameters (PRMS has over 130 tunable parameters), which includes 2 canopy density parameters, shortwave radiation transmission through the canopy, soil recharge capacity and soil-water storage capacity.
There are dramatic diferences in pre- and post- wildfire watershed response. The above graph compares overland flow between the pre- and post- fire models at diferent precipiation events. Interestingly, the larget diference between the two models were at median soil moisture capacities. Stay tuned for an upcoming USGS Scientific Investigations Report and an ISI Journal article.PRMS modeling, post-fire watershed response
I was recently awarded a competetvie grant from the South Central Climate Science Center to qauntify the effects of forest canopy disturbance on the underlying snow water resources.
Snow accounts for approximately 70% of total streamflow from the South Western US region’s primary water arteries, the Colorado River and Rio Grande. Forests within these watersheds are affected by climate change, modifications in land management, and a variety of natural disturbances such as wildfire and bark beetle attacks, all of which create uncertainty regarding the fate of this major water source. No studies have characterized or quantified the effects of forest fire on snow-water resources under a range of meteorological conditions that represent potential future climate scenarios. Until recently, forest snow models have been ill equipped to accurately quantify under-canopy snow accumulation and melt processes as they relate to the overlying forest canopy structure. Without tools to simulate and analyze potential impacts of wildfire on snow-water resources, effective water-resource planning, watershed protection, post-wildfire risk assessments, and future forest gap and growth analyses will have limited scientific basis or applicability in regions with wildfire potential. In order to better constrain forest-snow processes, a new snow-melt model has been developed that directly integrates LiDAR data for a high resolution representation of the modeling domain. A new process-based snow-interception model has also been developed that integrates LiDAR data to characterize the forest canopy.High Resolution Snow Modeling, Forest Canopy Disturbace, Aerial LiDAR
The Water Cycle is affected by our changing world and climate; as such, we need more accurate measures to quantify the distribution of this critical resource over the landscape.
