Abstract

In this paper, a new methodology is presented for analyzing urbanization of irrigation districts within a region. This method is based upon the fragmentation of irrigation water distribution networks (i.e. canals, pipeline, reservoirs, water control structures, etc.) due to urban growth and expansion. Two functions are presented, the fragmentation index which defines the extent that the water distribution network (i.e., canals and pipelines) is impacted by patchy urbanized areas within an irrigation district, and the fragment density index which identifies the most impacted locations in the region. Urban expansion and the use of these indexes are demonstrated through an analysis of 28 irrigation districts located in the Lower Rio Grande Region (LRGR) of South Texas over a 10year period.
