what characterizes cities from a geologic perspective?
Where do cities tend to be located in the physical landscape? They often are located along transportation routes, in valleys, along rivers and on deltas, on the piedmont at the foot of mountains. Example of major cities along the fall line of the Eastern U.S. Coast. One can classify urban areas on basis of geologic setting: coastal setting, coastal-plain fluvial setting, piedmont setting, lake margin setting. Cities within each group could have common geologic problems. Try to see how many cities could fall into these catogories. Think of some cities that do not fit into these categories. Why was the city sited there? What might be environmental problems common to many cities? • Many cities have to deal with fluvial systems so flooding is a common concern. • Since it is a setting of intense construction, engineering properties of the substrate. • Associated with construction is often accelerated erosion (examples for Omaha). • In certain areas earthquakes, of distinct concern because o
