• October 1996 to October 1997- University Corporation for Atmospheric
Research (UCAR) Visiting Scientist at the National Weather Service,
Office of Hydrology, Hydrologic Research Laboratory in Silver Spring,
MD. Research and development focused on two(2) major areas of water
resources. (1) Distributed Hydrologic Modeling - This research included
hydrologic model development and testing, investigation of space and
time scale sensitivity of both models and model parameters, and the
use and development of Next Generation Weather Radar (NEXRAD) precipitation
estimates in hydrologic modeling and flash flood guidance. (2)River
Mechanics - Present work focused on the development of a graphical user
interface (GUI) input routine for the National Weather Service unsteady
flow model, FLDWAV.
• 1992 to 1996 - "A Hydrologic Model for Use with Raster
Data Structures." Research conducted in conjunction with Penn State
University - Earth System Science Center and the National Aeronautics
and Space Administration. This research was performed in partial fulfillment
of a Doctor of Philosophy Degree in Civil Engineering. This project
includes the development and testing of a hydrologic model at Penn State.
The model utilizes raster data sets such as Digital Elevation Models
(DEM's), soils, and land use/land cover data. Precipitation is supplied
by the user or obtained from a mesoscale model being used at Penn State.
Overland flow is approximated using a finite difference solution of
the kinematic wave equations and finally, a modified Muskingum-Cunge
channel routing scheme is employed. Additionally, hydrologic abstractions
are estimated using one of several methods, including the Soil Conservation
Service curve number method and solution of the Green-Ampt equation.
The hydrologic model has been successfully tested on small watersheds
using precipitation supplied by recording stations within the basin.
The current thrust of the research is to investigate the model’s
ability to simulate precipitation responses in large basins by coupling
the spatially distributed hydrologic model with a mesoscale model. Current
model development is focusing on incorporating other processes into
the model to allow for the simulation of long term hydrology, in order
to assess the inter-annual variability in the hydrologic cycle.
• January 1996 to September 1996 - Post-doctoral research investigating
the impacts of climate variability on hydrology, water resource allocation,
and socioeconomic patterns within the Susquehanna River basin. This
research entails data collection, data base management and development,
statistical analysis, and climate and hydrologic modeling. Research
aimed at investigating the extent to which various socioeconomic activities
are affected by climate change, as well, the planning and management
of water resources throughout the Susquehanna River Basin. Modeling
involves hydrologic budgets, and integrating climate variability within
hydrologic models to ascertain basin water resources.
• January 1995 to Summer 1996 - Project involving Penn State University,
the Federal Energy Regulatory Commission (FERC), and a private consulting
firm. This work entails evaluation of the FERC's guidelines for computation
of the Probable Maximum Flood (PMF) at hydropower projects. Specifically,
this work will investigate the recommended procedures for hydrologic
loss estimations, snowmelt determinations, unit hydrograph applications,
and channel and reservoir routing procedures. A companion document for
Chapter VIII of the FERC's Engineering Guidelines for the Evaluation
of Hydropower Projects is to be produced. This document will elaborate
on the assumptions, limitations, and data requirements of the aforementioned
modeling processes. Additionally, examples of the various recommended
procedures will be detailed and published.
• June 1992 to August 1996 - Interdisciplinary research with other
members of the Susquehanna River Basin Experimental Team. This research
entailed extracting data from various sources including satellite images,
aerial photographs, and other spatial data sets. Investigations include
land use and land cover, soils, and general topographic information.
Data sets utilized include STATSGO, SSURGO, EPA-EMAP, LUDA, LANDSAT,
AVHRR, and SPOT. Image processing and GIS packages include ARC/INFO,
GRASS, ERDAS/IMAGINE, IDRISI, and SPYGLASS. Investigations also include
examining the effects of human influences on natural resources and ultimately
the possible effects on the hydrologic cycle and climate.
• August 1989 to May 1992 - "Bridge Scour Prediction Methods
Applicable to Streams in Pennsylvania." - Research project in conjunction
with the Pennsylvania Department of Transportation, submitted as PaDOT
Research Project 89-03. This two-year research project consisted of
pertinent data collection through field surveys, sampling, inspection
reports, and interviews with a regression analysis being performed on
the data base. Also, several equations were examined for their applicability
to streams in Pennsylvania.
