Dr. Gupta's conducts research on various aspects of Soil and Contaminant Hydrology, Waste Utlization, Soil Management, and Pavement Materials. His recent research interests are in water quality, landscape hydrology, soil structure, and soil mechanics.
The recent projects include:
Effect of antibiotic feeding in animals on the spread of antimicrobial resistance in the environment,
Fate and transport of antibiotics in soils,
Antibiotic uptake by plants
Effect of dense soil conditions and addition of recycled materials on hydraulic properties of subgrade under pavements,
Role of soil unsaturation on shear strength, and
Sediment pollution from mass wasting along river banks
Dr. Gupta's earlier work involved:
quantifying residue cover using LANDSAT data
tillage and manure interactions on surface and subsurface water quality
effect of winter waste water application on percolating water quality
effect of sugarbeet waste on surface and subsurface water quality
role of earthworm macropores on preferential water and contaminants transport through soil
use of drip irrigation to minimize nitrate leaching in potato production
soil structure simulation using a 3-D network model and percolation theory
raindrop impact on soil detachment
tillage and surface seal effects on water infiltration
modeling tillage and compaction effects on soil physical properties and processes
models for predicting excessive soil compaction
tillage and crop residue effects on soil temperature and corn emergence
availability of biomass for energy production, and
modeling simultaneous flow of water and solutes through soil.Bank Erosion Estimation Using Airborne Laser Altimetry
Measurement & Modeling Contaminant Transport Strategies in Roads Tracing the Path of Antibiotic Resistance THIS WORK WAS DONE IN MID 70'S UNDER THE LEADERSHIP OF BILL LARSON
