The terrestrial water cycle is being altered by human activity such as water diversion and withdrawal for agricultural use. In this study, a global water resource model was enhanced to perform a simulation considering nonlocal water resources which is diverted from remote places. In this study irrigation water requirement was met by major four major sources: river, reservoirs, nonlocal water sources and nonlocal water source. We created geographical data of water diversion systems for five regions of major irrigated cropland. The simulated result showed that annual irrigation water requirement for nonlocal water resources were 62km3 and that account large part of total irrigation water requirement in our subject areas.
