The quality and quantity of water have a strong relationship. As the quantity of the water deteriorated decreases, the quality of the water goes worse. Even if the volume of the corrupt water is large enough, it takes much time and cost to use it again. By the climate change after industrialization, the whole world has realized the importance of water. Even though homeland (Korea) has not lower precipitation compared to other countries, our country is classified as the water scarce country. Of course, it is pointed out that the criteria is a simple indicator only considering the boundary of land area, the population density and the amount of rainfall for the warning about the water scarce as increasing population. In addition, the World Water Forum in 2006, published in the water poverty index (WPI), shows that it is hard for people tonotice if we are in the water scarce country or not, for homeland(Korea) belongs to the relatively benign group. It might cause controversy about which is correct. However, it is certain that our nation made up of 70 percent of the land area with high coefficient of river-regime will have difficulty in making the water clear compared to other countries.The purpose of this study is variation and correlation analysis of the regional hydrological data and electrical conductivity. It is possible to predict future changes in the region by analyzing the changes in the characteristics and trends through past observations of water quantity and quality factors. The regional water quantity quality characteristics and influencing factors can be screened by analyzing the correlation of the electrical conductivity and hydrological data. If take advantage of the selective regional water quality and quantity influencing factors through changes in the characteristics and correlation analysis, will be able to determine the more efficient management of water resources. |
