Image Analysis and Numerical Modeling of the Chrome Dilution in Irrigation Channels

This project proposes an image analysis of chrome in irrigation channels of variable slope and his numerical modeling. The experiment is based on a scale model of irrigation channels in the region of Irapuato, Gto. Mexico for the production of sorghum and corn. The concentrations reported in extraction wells for irrigation, ranged from 3 to 10 gm/L. The purpose of this study is to quantify the dilution of contaminant in different sections of primary irrigation channels using advection-diffusion-reaction equations.

Results show the behavior of chrome dilution in a water column and in the x-y plane. Firstly, through the use of image analysis, the concentration of chrome is estimated by color analysis in digital frames extracted from a set of videos using computational vision techniques. Subsequently, this analysis is compared with the numerical modeling using the FLOW-3d software. An error of 2.87% is observed in the quantification of the concentration, as well as an error of 1.40% in the estimation of the dispersion and dilution of chrome in the physical model.
