Graduate Research Assistant  - 

- Modeling the multistate “age” of water across the entire active hydrologic continuum, under a range of meteorological forcings and hydro-geologic parameters • A fully coupled spatially distributed flow – solute transport – age of water model was developed and integrated with Penn State Integrated Hydrologic Model • Model solves multistate coupled flow-transport-age (Q-C-A) dynamics of conservative tracers and provides an estimate of residence time of the watershed • Model was used to gain insights into classic problem of old and new water in stream runoff at Shale Hills Susquehanna critical zone observatory using observations of deuterium isotope concentration in precipitation as input.

- Fully coupled modeling of hydrologic and solute transport • A spatially distributed physically-based solute transport model was developed, which was coupled with the multistate, multi-physics representation of watershed in Penn State Integrated Hydrologic Model system • It simulates coupled flow and solute transport for 1D channel routing, 2D surface overland, 2D subsurface flow, interception, snow-melt, evapotranspiration, macro-pore flow, and groundwater recharge using the semi-discrete Finite Volume approach.

- Using integrated hydrologic models to trace the source and dynamics of freshwater discharge in a coastal watershed • Processes representing spatially distributed surface and subsurface freshwater exchange between coastal watershed and tidal estuary were coupled in Penn State Integrated Hydrologic Model (PIHM) • Coupled model was used to investigate spatial variability in hydrologic processes in a coastal watershed at Rhode River basin (an experimental watershed managed by Smithsonian Environmental Research Center, SERC) • The spatial and temporal behavior of freshwater discharge to the estuary along the shoreline was estimated under varying climate and tidal forcing.

- Location, function and seasonal dynamics of wetlands in Susquehanna river basin and impacts of global climate change: An integrated, physics-based distributed modeling approach • In this research role of distributed models in predicting the location, ecologic function, and dynamic seasonal response of wetland was examined • “Nested-modeling” approach facilitated by PIHMgis, was used to capture high-resolution spatial variability in hydrology at a wetland ‘supersite’ with critical wetland specific monitoring • Model simulated spatial extents of wetlands were validated against wetland polygons delineated in National Wetland Inventory (NWI) • Impacts of climate change on the watershed and wetland hydrology were assessed by evaluating hydrologic changes under two long-term climate scenarios (a) Historic (1979-1998), and (b) Scenario (2046-2065), both obtained from dynamic downscaling of Meteorological Research Institute (MRI), Global Climate Model (GCM).

- Bridging the gap between geo-hydrologic data and integrated hydrologic model: PIHMgis • A strategy for coupling of distributed hydrologic model and Geographic Information System was established to meet pre/post processing of data and visualization through development of object oriented shared-data model • PIHMgis, an open-source, platform independent, tightly-coupled GIS interface to PIHM was developed • PIHMgis provides improved model-data coupling by creating a strategy to drive distributed model using national data products.

- Coupling of hydrologic processes in Little Juniata watershed • Coupling of the hydrologic processes across disparate spatio-temporal scale was demonstrated in Little Juniata river, which is located in south-central Pennsylvania, encompassing 865 square miles.

- An efficient domain decomposition framework for accurate representation of geodata in distributed hydrologic models • Research outlines a flexible domain decomposition strategy and related algorithms for efficient and accurate integration of the physiographic, climatic and hydrographic watershed features in distributed models. The framework is critical for producing high quality, multi-resolution, adaptive and nested grids with least computational expense for watersheds of multiple scales.

- Object oriented shared data model for GIS and distributed hydrologic models • The design of an object oriented “shared data-model” taking into consideration the data type descriptions, identification of data-classes, relationships and constraints is presented. Data-model utilizes extensive GIS data and enables seamless data flow, increases accuracy, reduces the model setup time and analysis of model outputs, • Strategy makes it easy to perform sophisticated numerical modeling procedures (e.g., real time forecasting, sensitivity analysis) and integration of complex data objects in model.

- Automated detection and spatio-temporal classification of channel reaches in semi-arid Southwestern US • An automated method for the detection of stream channels and their classification into ephemeral, intermittent and perennial reaches using remote sensing, ASTER Level 1B data was developed • Steps include calculation of NDWI map for area followed by bi-level classification to obtain watered channel and change-detection to attain channel classifications.

- Impact of dynamic response characteristics on uncertain streamflow prediction • Regionalization approach was used to understand the influence of watershed physical characteristics on uncertainty in model predictions in ungauged catchments.

- Development of software for furrow irrigation • A user friendly software for the hydraulic simulation of furrow irrigation was developed • Graphical user interface (GUI) of the software was designed using MS Visual Studio and C++ • Accuracy of developed software was tested against field observed data • Performances of Kinematic-Wave model, Volume Balance model, Zero Inertia model, and Full Hydrodynamic model were compared.

- Evaluation of traditional and non-traditional optimization techniques for determining well parameters from step-drawdown test data • Three standalone and interactive computer programs for the optimization of hydraulic parameters of production wells were developed • Methods use graphical analysis of step-drawdown pumping test, nonlinear optimization techniques (Levenberg–Marquardt and Gauss–Newton), and genetic algorithm for optimization • Inter-comparison of results were performed.
