I have primary interests in water resources management, hydrology, geomorphology, and stream and wetland restoration. My current research projects reflect these interests.
currently working on a collaborative project (with C Jantz, T Hawkins, S
Drzyzga, S Goetz, and P Jantz) to address how multiple stressors of
climate change and land use/land cover change will alter hydrologic
systems and forest ecosystems in the Delaware River Basin. We are
constructing a basin-wide coupled modeling framework that will support
societal adaptations to changing risks of floods, droughts, and forest
ecosystem response across multiple scales. My role is to model the
hydrologic response to extreme precipitation and drought under different
patterns and intensities of urban development expected over the 21st
century. We are working with resources managers to provide a scientific
basis to move planning to approaches explicitly acknowledging future
change and uncertainty. We appreciate the great support from the Delaware Watershed Research Fund.
I am also monitoring stream improvements on Larry's
Creek, Lycoming county Pennsylvania, an area that was significantly
impacted by channel straightening during the 1950s construction of State
Route 287. In October 2012 a section of stream was re-built to
mitigate bank erosion and includes bioengineering efforts such as "soil
burritos" and toe wood. Post-project monitoring includes documentation
of channel changes such as riffle-pool development and bank erosion.
recently completed research addressing stream temperatures in the
Navarro River watershed, northern California. Like many coastal
California rivers, the Navarro is host to endangered coho salmon and
steelhead trout and has been listed as impaired due to warm water
temperatures and excessive sediment loads. The TMDL (Total Maximum Daily
Load) for the watershed addresses those concerns, primarily via
riparian forest restoration and efforts to maintain minimum discharges
during the dry summer months. My work involved deploying a network of 24
temperature sensors to collect hourly data for two years and then using
that data to develop statistical and deterministic models of watershed
temperatures. I applied the Heat Source model to address potential
changes in water temperatures due to changes in climate, riparian shade,
and stream discharge. Two journal articles are in press from this work:

Other recent research efforts include:
I am also involved in a number of projects in the immediate Shippensburg area, focusing primarily on the Burd Run watershed. During 2001-2003 I served as co-Principal Director (with Brian Jaymes, Cumberland County Conservation District) in the effort to restore the Burd Run stream channel, riparian zone, and floodplain wetlands within the Shippensburg Township Park adjacent to the SU campus. The project was supported by a $129,000 Environmental Stewardship and Watershed Protection grant from Pennsylvania Department of Environmental Protection Growing Greener Program.
Much of the effort to work within the Burd Run watershed is the outgrowth of the "Burd Run Interdisciplinary Watershed Research Laboratory," established in 1999 with funding from the National Science Foundation. The Research Laboratory includes field and laboratory equipment that is available for faculty-student research.
Most of my research and teaching cuts across disciplinary lines, linking together elements from sciences such as hydrology, geomorphology, and aquatic biology. My approach is to better understand the biophysical system in order to support sustainable planning, management, and policy.
