- Bonding and Access to Capital Education Program
The Michigan Department of Transportation (MDOT) contracted with LEBS to provide technical assistance and coaching to small businesses as well as individual client management and wrap around support services for each of the small businesses accepted in the USDOT/MDOT Bonding and Access to Capital Education Program (BACEP). The purpose of the BACEP is to increase small business and DBE participation, as subcontractors or prime contractors, on USDOT and MDOT infrastructure projects

A Partial List of Our Team’s Past Projects
- High Performance Computer Applications in Hydrology
Dr. Sritharan accompanied by three (3) Water Resources Management students carried out research for the NASA sponsored High Performance Computing Summer Research Institute at Morgan State University, Baltimore, Maryland. The team performed simulation studies of surface water and sediment runoff using CRAY J916 computer at Morgan State University. Using the Computer Model KINEROS peak flows of runoff and sediment were correlated with watershed parameters using different storm patterns. Equations for peak runoff and time to peak were developed for general use by analyzing different watersheds of extents in the range of 250-750 square miles. The model is useful in tracking the after-effects of storms in watersheds by satellite imagery. The work culminated in a presentation by the team to NASA on evaluating satellite imagery needs for assessing the impact of flood events.
- Carbondale - Acid Mine Drainage Project
The Division of Reclamation (DOR) of the Ohio Department of Natural Resources (ODNR) assigned Dr. Sritharan and his team to undertake studies related to monitoring and evaluating a wetland constructed by the DOR in Carbondale, Ohio to mitigate acid-mine drainage from an abandoned coal mine site. This assignment by ODNR was an important project in the southeastern part of Ohio The study resulted in developing an empirical relationship for iron removal efficiencies of wetlands constructed to ameliorate effects of acid mine drainage that can be used to design wetlands and assess existing wetlands.
- Applied Remote Sensing for Evapotranspiration United States Bureau of Reclamation (USBR)
In this project for the USBR, LEBS team members lead the $3 million effort and collaborated with Ohio View Consortium Universities, Ohio Aero-Space Institute, Colorado State University, Utah State University, USDA-ARS Water Conservation Lab, USGS, and NAS. Research objectives included assisting the USBR in applying advanced remote sensing technologies for water management in the arid West with a specific focus on applying remote sensing technologies for estimating large area evapotranspiration. Pilot areas were located in Lower Colorado Region – Blythe, CA and in Great Plains Region in Colorado – Arkansas River Valley.
- Soil Sampling for US Army Corps of Engineers -Huntington District, WV
At regular intervals, LEBS team members conducted soil sampling tests for the US Army Corps of Engineers (USACE) of the Huntington District, West Virginia, for river systems in Great Lakes and Ohio River Divisions. Soil gradation tests consisting of sieve analysis, hydrometer tests, and Atterberg limit tests were typically investigated. Throughout the project our team developed improved procedures for the hydrometer tests performed. We studied Ohio, Monangahela and Illinois rivers and bed samples were analyzed among other systems. Assistance was given to the Huntington District USACE for studying the habitat structures in the Marmet Pool of the Kanahwa River, Huntington, WV.
- Biospheric - Atmospheric Interactions
Dr. Sritharan and two Water Resources Management students were assigned to the Biospheric Sciences Division of NASA’s Goddard Space Flight Center, Greenbelt, MD. They engaged in adapting the Simple Biospheric Model (Sib2 Model) which is a sub-component of Global Circulation Model (GCM) for predicting evapotranspiration and yield performance from agricultural areas using satellite data. The team recommended new modifications to the radiation component after finding needs for improvement in the work by NASA in this regard.
- Environmental Assessment Project- University of Zambia
In collaboration with the University of Zambia, LEBS team members assessed the energy needs and the hydro-power potential and environmental improvement in Zambia. A faculty and student team led by LEBS’ Dr. Okunade visited University of Zambia (UNZA) in Lusaka and made a preliminary assessment in collaboration with UNZA.
- Hydrologic Redistribution of Soil Moisture in Senegal, West Africa
Senegal graduate students and LEBS scientists were involved in this project which was located in Dakkar and Thies, Senegal. This project investigated the beneficial effects of native shrubs in reducing water stress in the Senegalese crops in the dry season. This project involved several disciplines including Water Resources Management, Environmental Engineering and Biology.
- Hydraulics of Surface- Subsurface Flow Interactions
LEBS team members were engaged by the Egyptian Council of Universities with funds from USAID to be part of the Wadi- El Assiuti Groundwater Resources Evaluation Project, in Egypt. Drs. Okunade and Sritharan conducted studies in collaboration with researchers from Assiut University in Egypt. The work involved research related to the feasibility study of developing groundwater resources for agricultural development on a Wadi (dryrun) basin East of River Nile in the middle of Egypt. The LEBS team conducted a study of the surface hydraulics of flash floods including sediment transport phenomena in the area as it impacts the contribution to groundwater. Our team members developed a surface-subsurface flow interaction modeling procedure involving hydraulic modeling of surface flow coupled with the unsaturated flow in dry run (wadi) beds. This would later enable further studies by Egyptian researchers to investigate groundwater recharge in the Wadi El Assiuti basin.
