The Great River of Caranus

The Great river at 30 degrees south.  The Tropical rains of the Winter mix with the Equatorial rains, the mountains scoop more rain out, it is only in the Summer when the the weather is drier in in this area and at the equator is the river slower.


The Great River at about 40 degrees South is fuller for more of the year.  The scale on the y-axis is in 10,000 of cubic meters of water per second.  At this point it is a ten Amazon rivers, so it is deeper and a lot broader and a lot swifter.  The river floods three to five times a long year, mostly in the early and late winter, but also in the late spring.


The Great River at 50 degrees south peaks in the early Spring.  Precipitation in the Winter is mostly snow at this latitude and so there is a peak when it melts in the mountains.  The floods are less frequent, about three years of the cycle, but they are also more severe. The calculations for this water flow do not include the tributaries from the East, but they are drier regions; still they drain a huge area and would bump the summer volumes up a lot, perhaps to the 200 mark.  The 200 mark would be close to the brim of the river, and it would only flood after 250.  Therefore, there would be a large flood in the early spring period and a minor flood in the first summer month.


At the 60 degree mark, the Great River approaches the delta.  The Spring flow from within the continent would boost volumes up to 300 mark, making it over 15 times the size of the Amazon River.  The four years of mid Spring would see the largest flood time and this is due to 8-10 years of winter snows melting.  At the peak it would see more than twice the flow passing through the river.

The Great River flows along a cordillera mountain chain that causes a lot of rain to fall.  The river travels the distance of the chain and drains nearly 40% of the continent.  It is a Mature river, and so it has a wide floodplain and meanders most of the length, with plenty of  oxbow lakes littering its edge.
