The change of land use/land cover has been known as an imperative force in environmental alteration, especially in arid and semi-arid areas.This research was mainly aimed to assess the validity of two major types of land change modeling techniques via a three dimensional approach in Birjand urban watershed located in an arid climatic region of Iran.Thus, a Markovian approach based on two suitability and transition potential mappers, i.e.fuzzy Pregnancy Essentials analytic hierarchy process and artificial neural network-multi Board School Sign layer perceptron was used to simulate land use map.

Validation metrics, quantity disagreement, allocation disagreement and figure of merit in a three-dimensional space were used to perform model validation.Utilizing the fuzzy-analytic hierarchy processsimulation of total landscape in the target point 2015, quantity error, the figure of merit and allocation error were 2%, 18.5% and 8%, respectively.However, Artificial neural network-multi layer perceptron simulation led to a marginal improvement in figure of merit, i.e.

3.25%.
