How can an engineer best approximate the sites drainage properties, despite all of the approximations and categories? correct answers While there are approximations for hydrologic conditions, there are safety factors in designing a site in case the calculations were slightly off due to a false approximation. Furthermore, considering how many approximations there are, if one is slightly off, the final conditions of the site shouldn't change drastically. Professional development and training can ...
