IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

A new simulation-optimization approach for simultaneously identifying the spatial distribution and source fluxes of the areal groundwater pollution sources
Author : M. TAMER AYVAZ (1)
ABSTRACT
This study proposes a new simulation¨Coptimization approach for simultaneously identifying the spatial distribution and
source fluxes of the areal pollution sources in groundwater systems. In the proposed approach, groundwater flow and
pollution transport processes are simulated via MODFLOW and MT3DMS models in the simulation part. These models are
then integrated to an optimization model where a binary genetic algorithm (GA) is used. In the proposed GA based
optimization model, finite difference grid blocks of the given aquifer domain are considered to be the potential areal pollution
source locations. The main objective of the GA is to evolve the source fluxes and spatial distributions of source locations
through genetic operators by minimizing the error value calculated between the measured and simulated pollution
concentrations at given monitoring locations and times. The performance of the proposed approach is evaluated on a
hypothetical aquifer model for 4 different pollution source distributions. Identified results indicated that the proposed
simulation¨Coptimization approach may be used as an effective way to solve the areal pollution source identification
problems.
