  • 1. Rivers, climate and vegetation 5th grade BY PATRICIA VELASCO RICO
  • 2. What is a river?  Rivers are moving bodies of water. River Thames
  • 3. Where does a river originate?  A river originates in the mountains, and flows into a sea, a lake or another river.
  • 4. The river originates in the mountains The river flows into a sea, a lake or another river
  • 5.  For example… A river that flows into an ocean: River Tajo
  • 6.  For example A river that flows into another river: Guadarrama river flows into Tajo River.
  • 7.  For example A river that flows into a lake: River Ter (Gerona) flows into Lago de Bañolas
  • 8. Elements of a river - The course  We can Distinguish 3 - The flow elements in a river - The flow regime
  • 9. What is the course of a river?  The course of a river is the route which a river takes from its source to the mouth.This is the source of the river This is the mouth of the river This is the COURSE of the river
  • 10.  There are 3 courses: Upper course Middle course Lower course
  • 11. Upper course  It is near the source. Here, the river is narrow. The river bed is steep, so the water moves fast
  • 12. Middle course  Here, the river is wider. The river bed is flatter, so the water flows slowly.
  • 13.  In the middle course, the river forms curves. These curves are called meanderings. This is a meandering
  • 14. Lower course  It is near the mouth of the river. The river is wide here. The river bed is very flat, so the water moves very slowly.
  • 15. What is the flow of a river?  It is the amount of water that a river carries. The more precipitacion there is, the greater the flow will be
  • 16. What is flow regime?  It is the flow pattern during the year. ◦ If the flow regime varies very little, it is regular. ◦ If the flow regime varies a lot, it it irregular River Ibia - Brasil
  • 17. Torrents, lakes and reservoirs  Water can also be found in other places on the surface of the Earth. ◦ Torrents ◦ Lakes ◦ Reservoirs
  • 18. Torrent  They are streams of water which form after heavy rains
  • 19. Lakes  They are large bodies of water surrounded by land.
  • 20. Reservoirs  They are man – made lakes. They produce energy, irrigate fields and supply water to urban areas. Canals and irrigation chanels are used for transporting water from a reservoir to other places
  • 21. Reservoir in Hillsborough County
  • 22. What is a watershed?  Rivers that flow into the same sea belong to the same watershed (vertiente).  The rivers in Spain flow into three different seas, in other words, they belong to three watersheds: ◦ Cantabrian watershed ◦ Mediterranean watershed ◦ Atlantic watershed
  • 23.  Meter imagen de vertientes hidrográficas
  • 24. Cantabrian Watershed  It has short, swift rivers.  They have a regular flow regime and abundant flow.  The most important rivers are the Nervion, Saja, Navia and Nalón
  • 25. Mediterranean watershed  It occupies about one third of Spain.  With the exception of the Ebro, the rivers are short and have irregular regimes.  During rainy seasons, they may overflow. In the summer, they may dry up.  The most important rivers are the Ebro, the Júcar, the Segura and de Llobregat
  • 26. Ebro River It is the most plentiful river of mediterranean watershed
  • 27. Atlantic watershed  It occupies more than half area of Spain.  The rivers have abundant flows and regular flows regimes.  In the summer they carry less water.  The most important rivers are the Miño, the Duero, the Tagus, the Guadiana and the Guadalquivir
