My work focuses on the collection of surface water flow and continuous water quality data. More recently this work has been extended to research the use of using surrogate models to estimate concentrations and loads for several different water quality constituents, including suspended sediment and chloride.

I've participated on several high-water mark and surveying campaigns related to large flood events following severe storms, including Hurricane Maria in Puerto Rico.  
 

CURRENT PROJECTS

Determination of time-of-travel, dispersion characteristics, and oxygen reaeration coefficients during low streamflows--Lower Tacony/Frankford Creek, Philadelphia, Pennsylvania Determination of time-of-travel, dispersion characteristics, and oxygen reaeration coefficients during low streamflows--Lower Tacony/Frankford Creek, Philadelphia, Pennsylvania

Time-of-travel, dispersion characteristics, and oxygen reaeration coefficients were determined by use of dye and gas tracing for a 2-mile reach of Tacony/Frankford Creek in Philadelphia, southeastern Pennsylvania. The reach frequently has concentrations of dissolved oxygen (DO) below the water-quality standard of 4 milligrams per liter during warm months. Several large combined sewer...
