Our clients have relied on us over the years to provide support with the latest computational tools and data analysis methods. Herrera develops and applies advanced hydrologic, hydraulic, gas, and air quality models, coupled with statistical programming, to quantify uncertainty in model results and in the process help our clients meet their project objectives. We are not only proficient with all the industry-standard models but use Python and R scripting to automate runs and customize analyses and graphical data presentations. We pride ourselves on the art of data presentation and enjoy working with complex data structures.
