ASCE has honored Krishna R. Reddy, Ph.D., P.E., D.GE, ENV SP, F.ASCE; Rajiv K. Giri, S.M.ASCE; and Hanumanth S. Kulkami with the 2018 Wesley W. Horner Award for the paper “Modeling Coupled Hydromechanical Behavior of Landfilled Waste in Bioreactor Landfills,” Journal of Hazardous, Toxic, and Radioactive Waste, January 2017.

In this nominated work, the researchers model for migration of contaminants in a multibarrier system for the safety assessment of near-surface disposal facilities (NSDFs). The model considers scenarios during the dumping period, after the dumping period, and after the closure of the NSDF. In all the scenarios evaluated, a third-order polynomial gave the best fit for the model and the coefficient of determination (R2) of 0.99 was obtained for a third-order polynomial. Reliability analysis was carried out, and the probability of failure of an annual radiation dose of 14C exceeding the permissible limits was estimated for different scenarios. The results show that the probability of failure of the system in all scenarios is very low, confirming the adequacy of the system.

The Wesley W. Horner Award recognizes papers that have contributed to the areas of hydrology, urban drainage, or sewerage.
