The rivers connectivity in the Community of Madrid: an environmental review through global projects of hydrographic mapping
Abstract
For thousands of years the rivers played a fundamental role in human societies, providing water for domestic and agricultural use and also as an essential medium for transportation, industrial production and generating electricity. For this reason the rivers are essential sources of economic wealth, environmental health and also elements of cultural cohesion. Over the past decades, due to the increasing need of fresh water, the number of dams and reservoirs have been increased drastically all over the world, putting in danger the connectivity of many rivers and causing serious environmental repercussions. This study focuses on the analysis of the longitudinal connectivity of the rivers inside the Community of Madrid; through the comparative evaluation of different global projects of hydrographic mapping, with Geographic Information System (GIS) in high spatial resolution.
