In total, 23 water crisis variables are used for constructing an SE model. Amongst them, 20 variables are endogenous observed variables, two latent variables, and one dependent variable. These variables are selected from reviewing the water crisis, focusing on more profound variables that affect the crisis of water in Dhaka city. The variables are given in Table 2.
