Abstract

Landscape indices can be used as an approach for predicting water quality changes to monitor non-point source pollution. In the present study, the data collected over the period from 2012 to 2013 from 81 water quality stations along the rivers flowing in MAZANDARAN PROVINCE were analyzed. Upstream boundries were drawn and LANDSCAPE METRICS were extracted for each of the sub-watersheds at class and landscape levels. Principal component analysis was used to single out the relevant water quality parameters and forward linear regression was employed to determine the optimal metrics for the description of each parameter. The first five components were able to describe 96.61% of the variation in water quality in MAZANDARAN PROVINCE.Adaptive Neuro-fuzzy Inference System (ANFIS) and multiple linear regression were used to model the relationship between LANDSCAPE METRICS and water quality parameters. The results indicate that multiple regression was able to predict SAR, TDS, pH, NO3-, and PO43- in the test step, with R2 values equal to 0.81, 0.56, 0.73, 0.44. and 0.63, respectively. The corresponding R2 value of ANFIS in the test step were 0.82, 0.79, 0.82, 0.31, and 0.36, respectively. Clearly, ANFIS exhibited a better performance in each case than did the linear regression model. This indicates a nonlinear relationship between the water quality parameters and LANDSCAPE METRICS.Since different LAND COVER/uses have considerable impacts on both the outflow water quality and the available and dissolved pollutants in rivers, the method can be reasonably used for regional planning and environmental impact assessment in development projects in the region.
