| RESEARCH INTERESTS Earth System Science: hydrologic
and geomorphic controls on
ecosystem processes; watershed-scale restoration Ecohydrology: benthic light availability; spatio-temporal trends in water quality; biotic responses to flow variability and watershed disturbances Fluvial Geomorphology: sediment erosion; suspended sediment transport; reservoir sedimentation; channel evolution Anthropogenic Influences in Watersheds: dam removal; urbanization; stream restoration |

Current Research Project |
||
| I am measuring spatio-temporal trends in sediment transport and water quality associated with dam removal at four locations: Big Spring Cr., WI; Baraboo R., WI; Deep R., NC; and Little R., NC. I am also creating a Benthic Light Availability Model (BLAM) that predicts the magnitude and duration of photosynthetically active radiation (PAR) on the riverbed based on riparian shading and optical water quality. | ||
 Hemispherical canopy photo of Big
Spring Creek, WI
This image is
used with Gap Light Analyzer software and solar radiation data to
determine the amount of PAR reaching the river surface. The water
column light attenuation coefficient is then used to derive PAR at the
riverbed.

 Carbonton Dam
on Deep River, NC
This dam was removed in Dec. 2006. I am currently
monitoring sediment transport and water quality upstream and downstream
of the former reservoir to determine the downstream geomorphic and
ecological impacts of dam removal.

Thesis Research Project I examined the
controls of hydraulic erosion of cohesive
riverbanks. The study was conducted on Sand River (Aiken, SC), an
urban ephemeral stream with active bank erosion. Using the
properties of magnitude, duration, event peak, and variability, excess
shear stress distributions were evaluated at three cross-sections
within
the channel. Results indicated that hydraulic erosion rates of
cohesive riverbanks are dictated by flow intensity (i.e. event peak and
variability).
