I have primary interests in water resources management, hydrology, geomorphology, and stream and wetland restoration. My current research projects reflect these interests.
I am 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 also continue my 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 current work (2018-2019) involves documenting the streamflow and water temperature benefits of agricultural water conservation projects and is conducted with the Mendocino County Resources Conservation District and funded by the National Fish and Wildlife Foundation. Prior work (2014-2016) was based on deploying a network of 24 water temperature sensors to collect hourly data to support 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. See:

Other recent research efforts include:
- From 2012-2017 I monitored 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 included documentation of channel changes such as riffle-pool development and bank erosion.
- I collaborated with Kurt Fuellhart to study the economic costs and savings of various residential water conservation programs in Shippensburg, PA. See: Woltemade, C. J. and K. Fuellhart. 2013. Economic efficiency of residential water conservation programs in a Pennsylvania public water utility. The Professional Geographer. 65(1):116-129.
- I worked with Erick Ammon (M.S. Geoenvironmental Studies student) to evaluate the impact of soil compaction in residential lawns on infiltration and runoff rates. See: Woltemade, C.J. 2010. Impact of residential soil disturbance on infiltration rate and stormwater runoff. Journal of the American Water Resources Association. 46(4):700-711.
- I worked with Jinnieth Woodward (M.S. Geoenvironmental Studies 2006) on the water quality benefits of a small restored wetland in Shippensburg, PA. With 2 years of monitoring data we found that the wetland removes over 60% of the nitrate that enters the wetland from a limestone spring. See: Woltemade, C.J. and J. Woodward. 2008. Nitrate removal in a restored spring-fed wetland, Pennsylvania, USA. Journal of the American Water Resources Association. 44(1):222-234.
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.
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.
