Answer:
Cities near water allow for water transportation, which is generally faster than land transportation. This is especially true in older times (before the invention of trains, for instance). Cities with access to water trading routes could deliver great amounts of goods for trade with other coastal cities, which ment more money and trade goods for both settlements, and allowed for cultural mixing. Landlocked cities, on the other hand, were limited to land trade routes only, which tended to be slower and in some cases more costly.
