With climate change and increased anthropologic activities on the rise, the coasts will face higher threats. Researchers are considering many forms of "green infrastructure" to protect against storm surge, including coral reefs, seagrasses, and mangrove trees. Mangroves are able to dissipate wave energy because of their complex prop root system. Under the direction of Dr. Heidi Nepf, I conducted experiments to determine the drag coefficient of mangrove trees. The drag coefficient is important to calibrate numerical models that can be used to plan future mangrove reforestation projects.
Rhizophora mangle can grow in a variety of environments, including saltwater, freshwater and brackish water
The experiments were conducted in a flume with 32 1/12-scale model mangroves.
I presented this research at the poster session of the Massachusetts Institute of Technology Summer Research Program.
This research was performed under the direction of Dr. Jorge Abad. Through ArcGIS analysis, I have been creating a baseline study for the morphodynamics of the Peruvian Amazon River by performing a spatial and temporal analysis of the river system from 1985-2010. The purpose of this research is to understand the migration of the river and the processes that form the river's unique geomorphic characteristics. This research will be important for future development in the Amazon region, because the migration of the river will have huge implications on navigation and accessibility.
The Peruvian Amazon River develops a unique anabranching structure to dissipate the large amounts of energy that is transported through its channels.
Water level fluctuations are incredibly apparent during the dry season when the channel bars are exposed.
In a field campaign to the Pacaya Samiria National Reserve during the CREAR-ED-SPA course, I learned about vegetation in the Amazon.
>My senior design group worked in partnership with the Pittsburgh Office of the American Rivers organization to perform the design work necessary for the permitting process to remove the Franklin-Glass Dam in Renfrew, PA. This dam, located on Connoquenessing Creek just downstream of the junction with Thorn Creek, is being removed to restore the river to free-flow conditions, allowing for improved fish passage and sediment transport. This project was incredibly multi-disciplinary, requiring work in hydraulics, ecology, environmental engineering, and construction management.
We need to survey the cross sections of the creek both upstream and downstream of the dam.
This dam, built nearly 100 years ago, needs to be removed because it is obsolete and harmful both to the ecology and kayakers.
