Estimation of changes in water quality parameters including electrical conductivity along a river is essential. In this paper, ANN and ANFIS-SC were used to estimate the ECs of the Nekarood River, North Iran, from 1992-2013. The study period was divided into two periods of dry and wet, based on the river flow rate. Then, Using the PCA, the effective parameters in EC estimation were determined...
The land-use change, cutting forest trees and the grasslands conversion to agricultural lands destroyed natural ecosystems and also current or future production capacity reduce and these are harmful effects on the soil physicochemical characteristics. This study taken with aim, checking the role of forest-land change on some soil physical-chemical characteristics and then identify some effectiv...
