چکیده مقاله
Long term planning of water resources strongly depends on climate change and its effects on water resources and consumptions In the past, infrastructures planning and development programs wereintended based on historic data of climate But in recent decades according to the climate change impactson these planning and programs, moving toward estimation of its effects and finding appropriate strategies to overcome its risks has been interested One of these effects is impacted on water uses,especially agriculture In this research the impacts of climate change on water demands of agriculture in the downstream of dam in Zayandehrud river basin for future development of agriculture has been studied For this purpose we calculate the reference crop evapotranspiration with Penman – Monteithequation and gross water demands of agricultural sectors with AGWAT software Then the LARS WG model has been used for down scaling the parameters of climate change periods Results show that because of increasing in agriculture water demands, water resources management in the basin will face with big challenges in future So to reduce this hazard we propose a solution which works with changing in cropping pattern in the basin
