Our Story

URUNME was envisioned in 2014 to automate the tedious process of running the integrated Occoquan watershed model, operated and maintained at Occoquan Watershed Monitoring Laboratory located in Northern Virginia. The model is a set of computer models sequentially linked together to simulate the watershed’s hydrology and water quality. It consists of seven watershed models (HSPF) and two reservoir models (CE-QUAL-W2). At that time, this model was mostly operated manually which would take days, if not weeks, to create inputs, simulate a particular scenario, analyze output, and present visual results. After four years and more than 50,000 lines of code, URUNME has evolved into a feature-packed generic platform for environmental systems modeling.

Commonly, integrated modeling refers to the coupling mechanism used to automate the data transfer between different linked models. However, such an application, or any standalone model for that matter, requires extensive pre and post-processing for simulation. For instance, many environmental models lack advanced analysis and graphing tools, forcing the user to export the outputs to another software after each run. URUNME was developed with the goal to not only enable standalone or coupled operations of various models, but to automate the entire simulation process – creating inputs from different data sources, reading outputs, analyzing data, making statistical inferences and ultimately showing results in a visually-aesthetic and interactive way. It serves as an intelligent layer between the users, models, and data sources, practically hiding the underlying mechanics of the complex simulation process.

I am a PhD candidate and currently working at Occoquan Watershed Monitoring Laboratory in Virginia Tech. My professional journey of 20 years has included responsibilities with multinational companies and most recently heading an organization focused on environmental engineering. I am a passionate software programmer and have written software code in various computer languages. My postgraduate research was focused on the biochemical modeling coupled with asset management analysis, which led me to develop an intelligent process simulator, real time optimizer, and risk assessment software, called IViewOps (Intelligent View of Operations), which has been used in many wastewater treatment plants across the USA. As part of my PhD research, I have developed URUNME for integrated modeling to automate coupling, data analysis, statistics, visualization, scenario management and decision support systems.
