Topography and hydrography . Canelones Department, is characterized by flat lands and absence of relief (like most parts of Uruguay), with small coastal sand dunes at the south, and with meadows and woods in the center, north and west. The department is rich in waterways, with many rivers and streams. However, there are two rivers that stand out for their importance: the
Santa Lucía River and the
Río de la Plata, which is actually a sea of salt water. On the coastline formed by the Río de la Plata, there are many spa towns and their respective beaches. Santa Lucia River, meanwhile, forms the northern boundary with Florida, which is separated by a bridge known as the
Paso Pache.
Regions Despite being a small department, Canelones has a population of over 500,000 inhabitants and one of the highest population densities in the country with 114 inhabitants per square kilometer. The department is divided into approximately 20 sections. Within these, there are significant populations centers, some of which have the status of municipality, while others are part of cities formed recently by decree, and then there are also those that do not have enough inhabitants and are therefore often considered simple population entities with no mayor or government, remaining under the direct jurisdiction of the Municipality of Canelones (in Spanish,
Intendencia Municipal Canelones or
Comuna Canaria), which is based in the departmental capital,
Canelones. ==History==
