Urban systems, patterns and change.
Site refers to the characteristics of the spot that a settlement is found on.
Situation describes where a place is in relation to its surroundings - other towns, uplands and rivers, for example.
Most large cities have developed where both the site and the situation have been an advantage.
The site was often the original reason for a town to develop, whereas the situation may explain why a settlement remains small or grows into a town or a city.
Settlements with a long history were usually built on sites which were advantageous to early dwellers, such as:
defensive sites - on a hill, or surrounded by water
route centres - for example, where valleys meet
bridging points - an easy place to cross a river
wet/dry sites - on springlines or higher land above marshland
