Monitoring the Devastation of Isfahan Artificial Water Channels Using Remote Sensing and Gis

One of the most important rivers in central parts of Iran which has the major effects in the ecology of region is named “Zayanderood”. This river divides Isfahan city into north and south parts. “Sheikh Bahaee” (one of the most famous Iranian scientists) designed an intelligent water network (cannels derived from Zayanderood and passed through Isfahan city). The innovative and intelligent construction of this water network called MADIs was cited by many researchers. However, some changes have been applied to it which seem to have devastating influences especially in agricultural, urban and suburb environments. The aim of this paper is to design and develop a spatio-temporal GIS for analysing and querying the changes of this water network. The proposed system are designed and developed using two historical datasets; a map which has been produced in 1972 and a new map which is produced from Ikonos images using remote sensing techniques. The analyses show that the changes are mostly applied to ..... parts of the water network.
