This paper explores the strength of simulation techniques in water conservation by employing a cellular automata (CA) modelling framework. The CA-based model allows the examination of various scenarios with different hypotheses in the context of water resources management in Egypt. Moreover, sensitivity analysis is applied to test the robustness of the model's results. The empirical results show that both social media posts as well as the fear of building the Renaissance Dam in Ethiopia play a motivational role to encourage the individuals to conserve water in Egypt. This is supported by the effort of the most effective and influential categories (family, friends, and relatives, according to the results of the current study) because they are identified as the major influencers on the surrounding people in their social networks. For the results of sensitivity analysis, there is no significant difference between the results of implementing the model and the results of sensitivity analysis.
