What is the Relationship Between Water Hardness and Conductivity?

Project Description: 

Through a partnership with Jane Horwitz at the Penn Arts & Sciences Science Outreach Initiative and two teachers in the Radnor and Lower Merion school districts, activities for high school students studying mathematics and environmental science were developed for Honors and College Prep high school students.

This activity is presented here in the attached file.

Icacos Groundwater Monitoring

Project Description: 

A sample of data from three groundwater monitoring locations in the Icacos / Rio Blanco watershed are included here. Requests for a complete dataset will be considered, please email leonmi@sas.upenn.edu with an explanation of what you would like to do with the data. A complete dataset will be released to the public at a later date.

El Verde Stream Data

Project Description: 

This project presents data pertaining to the water chemistry of streams around the El Verde Field Station. Hobo U26 Dissolved Oxygen Loggers and U24 Conductivity Loggers collect data at a 15 minute time interval on the Q. Sonadora, Q. Prieta and Q. Toronja, in addition to a Hobo U20 Water Level logger at the Q. Toronja site.

Quantifying Hydrograph Unsteadiness and Sediment Cobble Dispersion

Project Description: 

Sediment transport is an intrinsically stochastic process, and measurement of bed load in the environment is further complicated by the unsteady nature of river flooding. Here we present a methodology for analyzing sediment tracer data with unsteady forcing. We define a dimensionless impulse by integrating the cumulative excess shear velocity for the duration of measurement, normalized by grain size. We analyze the dispersion of a plume of cobble tracers in a very flashy stream over two years.

Longitudinal Patterns in Stream Channel Geomorphology and Aquatic Habitat in the Luquillo Mountains of Puerto Rico

Project Description: 

The hydrologic, geomorphic, and ecological dynamics of tropical montane
streams are poorly understood in comparison to many temperate and/or alluvial rivers.
Yet as the threat to tropical freshwater environments increases, information on the
dynamics of relatively pristine streams is important for understanding landscape
evolution, managing and conserving natural resources, and implementing stream
restoration. This dissertation characterizes the geomorphology and hydrology of five
