The water quality prediction model raises the efficiency of the water quality management with control of be pollutant load and it is a method which is useful is used in water quality prediction of currently and future.
It used the QUALKO and the QUAL2E model from this research and Nak dong River Downstream water quality modeling it led and result the QUALKO and QUAL2E two model for comparative analysis.
In this research, objective segment's from the Samrangjin to the Weolchon, and the length is 26㎞, basin area is 505.7㎢.
It divided the basin with 5 reach and 26 element it composed the model and the calculation element is total 22 things.
It calculates a basin be pollutant analysis and a production pollutant loading, effluent pollutant loading, runoff pollutant loading. Pollution sources are Populations, Livestocks, Industries, Nurserys, Landfills, Land Uses.
The estimation results, the basin show BOD production pollutant loading 64,783.2㎏/day, T-N production pollutant loading 16,246.47 ㎏/day, T-P production pollutant loading 3,755.81 ㎏/day and BOD effluent pollutant loading 8,751.83 ㎏/day, T-N effluent pollutant loading 4,854.59 ㎏/day, T-P effluent pollutant loading 491.36 ㎏/day and BOD Runoff pollutant loading 894.60 ㎏/day, T-N Runoff pollutant loading 1,088.35 ㎏/day, T-P Runoff pollutant loading 26.25 ㎏/day.
The calibration and verification of the model executed the DO, BOD, T-N, T-P, Chl-a and Comparative analysis it did the application result of the QUALKO and the QUAL2E model with measurement price.
The DO, T-N, T-P and Chl-a simulation consistency of the water quality modeling result basin the price whose two models are similar came out. But the simulation consistency of the BOD the result of the QUALKO model to be nearer the QUAL2E model than reappearance characteristic was good in measurement price.
This result shows the fact the QUALKO model which complements the QUAL2E model could well be applied in Nakdong River Downstream.
