Editing Garonne (section)

===Course===
The Garonne follows the Aran Valley northwards into France, flowing via [[Toulouse]] and [[Agen]] towards [[Bordeaux]], where it meets the [[Gironde estuary]]. The Gironde flows into the [[Atlantic Ocean]] ([[Bay of Biscay]]). Along its course, the Garonne is joined by three other major rivers: the [[Ariège (river)|Ariège]], the [[Tarn (river)|Tarn]], and the [[Lot (river)|Lot]]. Just after Bordeaux, the Garonne meets the [[Dordogne (river)|Dordogne]] at the [[Bec d'Ambès]], forming the Gironde estuary, which after approximately {{convert|100|km|mi|}} empties into the Atlantic Ocean. Other tributaries include the [[Save (Garonne)|Save]] and the [[Gers (river)|Gers]].

The Garonne is one of the few rivers in the world that exhibit a [[tidal bore]].<ref name="Chanson_etal2010">{{cite book|author=[[Hubert Chanson|Chanson, H.]], Lubin, P., Simon, B., and Reungoat, D. |title= Turbulence and Sediment Processes in the Tidal Bore of the Garonne River: First Observations |url= http://espace.library.uq.edu.au/view/UQ:219711 |publisher=Hydraulic Model Report No. CH79/10, School of Civil Engineering, The University of Queensland, Brisbane, Australia, 97 pages|year=2010 |isbn= 978-1-74272-010-4}}</ref><ref name="Simon_et_al2011">{{cite book|author=Simon, B., Lubin, P., Reungoat, D., [[Hubert Chanson|Chanson, H.]] |title= Turbulence Measurements in the Garonne River Tidal Bore: First Observations |url= http://espace.library.uq.edu.au/view/UQ:243200 |publisher=Proc. 34th IAHR World Congress, Brisbane, Australia, 26 June – 1 July, Engineers Australia Publication, Eric Valentine, Colin Apelt, James Ball, [[Hubert Chanson]], Ron Cox, Rob Ettema, George Kuczera, Martin Lambert, Bruce Melville and Jane Sargison Editors |pages=1141–1148 |year=2011 |isbn= 978-0-85825-868-6}}</ref><ref name="Chanson_etal2012">{{cite journal|last1=Chanson|first1=Hubert|author-link1=Hubert Chanson|last2=Reungoat|first2=David|last3=Simon|first3=Bruno|last4=Lubin|first4=Pierre|title=High-frequency turbulence and suspended sediment concentration measurements in the Garonne River tidal bore|journal=[[Estuarine, Coastal and Shelf Science]]|date=December 2011|volume=95|issue=2–3|pages=298–306|bibcode=2011ECSS...95..298C|doi=10.1016/j.ecss.2011.09.012|citeseerx=10.1.1.692.2537}}</ref> Surfers and jet skiers could ride the tidal bore at least as far as the village of [[Cambes, Gironde|Cambes]], {{convert|120|km|mi}} from the Atlantic, and even further upstream to [[Cadillac, Gironde|Cadillac]], although the tidal bore appears and disappears in response to changes in the channel bathymetry.
