摘要: This paper analyzes the impacts of climate change and human pressures on Yazd-Ardakan aquifer using Hadley Centre Coupled Model, version 3 (HADCM ) circulation Model A 2 emission scenario. Water levels in study were simulated three-dimensional finite-difference groundwater model (MODFLOW 2000) with GMS 8.3 as pre- postprocessing software. Input for recharge time series under scenarios derived a regression equation based cumulative deviation from mean rainfall MATLAB. Human modeled through water requirements cultivated areas. Three to represent effects storage hydraulic head. Climate (scenario 1) will reduce result decreasing head by −0.56 m year −1 . Reduction pumping scenario (irrigation system modification) modification cropping patterns level fluctuation about −0.32 0.08 , respectively. Scenario is capable restoring protecting resources aquifer. The results this are useful obtain sustainable management
