Project Title: Modeling Runoff Flows into the Potomac River at the Featherstone National Wildlife Refuge
BASIS Advisor: Robert Biemesderfer
Internship Location: Center for Computational Fluid Dynamics, George Mason University
Onsite Mentor: Dr. Rainald Lohner
Pollution greatly impacts waterways and the health of the ecosystems they support. In the Potomac River specifically, development is increasingly polluting urban runoff and storm water entering the river. Water quality is important not only to the aquatic wildlife and surrounding environment but also to the five million people who rely on the Potomac for drinking water. My research will evaluate the land features at the Featherstone National Wildlife Refuge in order to determine significant factors for runoff flow in that particular riverbank along the Potomac. My research will provide information to local conservation agencies on methods to reduce the runoff that reaches the river at the Featherstone Refuges. Slowing the rate at which storm water reaches the river allows it to be diverted and filtered or absorbed into the soil so that fewer pollutants enter the water. Though I will investigate only a small region along the Potomac, every small change is progress toward cleaner water, and my findings may apply to nearby regions with similar characteristics.

Week 4: Latin Hypercube and SWAT
Hi, everyone! This week I continued improving my code for heat optimization, constraining the temperature to a certain value and adding terms to the equation I’m solving to essentially penalize (increase the cost function at that point) when the temperature exceeds this value. I had a lot of trouble with this, as the computed temperature […]
Week 3: Gradient Algorithms and Riparian Zones
Welcome back, everyone! This week I continued working on my genetic algorithm, fine-tuning it, then started on a gradient-based algorithm. Gradient algorithms find the minimum of a function by calculating the gradient (slope) at the current point and then taking a step (of prescribed size) in the negative direction. If taking that step doesn’t lead […]
Week 2: Optimization Algorithms and Riparian Buffers
Hi, everyone! Welcome back to my senior project blog. This week in my internship, I finished coding my heat optimization problem and began a new one–a genetic, or evolutionary, algorithm. Genetic algorithms are optimization methods where, in each generation, the best ‘individuals’ (data sets) are kept and their ‘chromosomes’ (characteristics/values) mixed to form new individuals. […]
Week 1: Internship Start
Hi, everyone! I started my internship this week! I learned a lot, experienced new things, and had fun. I used CAD software, a program Dr. Löhner coded, and ParaView to visualize fluid flows past objects. It was super cool! I included a picture below. I also met professors in the math department and watched a […]
Introduction
Hello! My name is Daria, and my senior project will explore runoff flows into the Potomac River at the Featherstone National Wildlife Refuge. Runoff in our area is becoming increasingly polluted due to urban development. This pollution harms not only the aquatic life and surrounding ecosystem but also the five million people who rely on the […]
