What had been there before the city was located?
To begin with, I propose to identify the elements of space that existed on the site before it was urbanised. This group of analyses includes examining the topographical conditions, the horizons. Identifying the flow of watercourses and other elements that we are sure existed before. An observation on your part could be to what extent they have been modified as a result of the urbanisation process: modifications to the landform, changes to the course of the river.
Climate change and problem of flooding
The direction of surface water runoff should be determined. This is especially important in recent times when extreme precipitation causes flooding and requires more attention to rainwater management.
