My research focuses on improving prediction of hydrologic and contaminant fluxes for better management of water resources using combination of field, laboratory, and modeling approaches. Current projects include: watershed modeling, development decision support tools for water resource management, green infrastructures for treating storm water in urban streams, fate and transformation of nitrogen, and organics in the vadose zone during soil-based wastewater treatment; modeling impacts of using tailored reclaimed water on nitrate leaching from irrigated crops, GIS-based nitrogen transport modeling for assessing aquifer vulnerability from onsite wastewater systems.
DST: Produced water management tool
The Decision Support Too (DST) [DST_Pr_v1.xlsm] is an
optimization tool for the selection of oil and gas coal bed methane produced
water treatment options for different wastewaters. Users can input feed water
quality from various sources by region. The DST selects treatment methods
capable of meeting beneficial use water quality requirement and calculates
costs associated with a treatment train. DOWNLOAD DST
STUMOD
STUMOD_v2 is a tool developed
for the purpose of predicting the fate and transport of nitrogen in soil
treatment units (STUMOD, or Soil Treatment Unit Model).
STUMOD calculates nitrogen species
concentrations, and the fraction of total nitrogen reaching the aquifer or a
specified soil depth. Input
data include parameters for hydraulics and nutrient transport and
transformation parameters. DOWNLOAD STUMOD
I am an Assistant Professor in Civil and Environmental Engineering at the SD Mines. I received my M.S. and Ph.D. in Environment and Water Resources Engineering. I worked as a research faculty and currently affiliated to Colorado School of Mines with a focus in watershed modeling and development of decision support tools for water resources management. Currently at SD Mines, I do research in water resource management and teach courses in hydrology and water resources.
