Numerical Identification Of BOD5 And DO Profiles Using Beck Modified Khanna Bhutiani (BMKB) Model

Abstract

Seeing the mounting public pressure at water bodies the need to protect it from pollution is essential where mathematical modeling is the best alternative as accepted by the decision makers. The use of system analysis and mathematical modeling for formulating and solving river pollution is of relatively recent vintage and has been used widely during last three decades. The present study was aimed to verify the BMKB model for river Ganges. The results of BOD5 shows the correlation DF (1,2) =2, n=3, F=. 588, r =. 603 between two values i.e. obtained by Winkler's method and by model, which is significant. The regression model with the two value for BOD₅ is found as r² = .307 and BOD₅ (t)= 9.6 - 0.03 BOD₅ (m). while the result of DO shows the correlation DF (1,2) =2, n=3, t=. 407, r =0.120 between the two value which is significant. The regression model with the two value is found as r² = .300 and DO (t) = 8.4 + 0.30 DO (m).
