Information About Rivers

Information About Rivers

Each river is characterized by an "international" scale of difficulty, starting from I to VI, based on a combination of information on technical difficulty and risk.

The scale has six basic steps and, with the help of signposts (+ and -), multiply and give a clearer picture of the difficulties that need to be addressed. Grade WW.I is the easiest case and does not require previous experience or a particular physical condition, whereas from WW.VV + the boat crew must necessarily be experienced, have a good physical condition and be able to synchronize so it performs well.

Each river is characterized by the degree of difficulty of its passages, the speed and volume of water flow, its depth and numerous other parameters that have to do with river hydrophography etc. Arachthos B! (WWIIII, 2 IV)


The degree of difficulty in a river can be slightly changed, e.g. from 2 to 3 or 1 depending on the volume and momentum of the water dropping eg. in the summer the waters are reduced 1.

Also, a river may have a different degree of difficulty in its various parts, and it may be possible to select the part you wish to cross eg. a place to be a Grade 3 and a Second Grade to Grade 2.


The degrees of difficulty are on a scale of 1ww - 5ww (ww - wild water):

1 - beginners 4 - advanced

The water moves quickly with small turbulence and waves

If the water moves, if there are small waves and maybe some rocks at the edge of the river, if the flow of the river does not require precision maneuvers from the boat, if you can get it downhill ...... this river is of 1st degree of difficulty.

These passages are rarely illustrated on maps, but beginners have to be careful. Large, strong but predictable vortices require precise handling in troubled waters. Dangerous points: small drops, rooftops etc there are depending on the river.

You can always understand when a 4th degree passage is in front of you.

The driver's silent concentration, the clarity of the orders, as well as the big and terse currents, the great inclinations and speed of the water, the precision maneuvers, and the big rocks are typical of this difficulty.

Rowers always feel it even if they go through closed eyes.

These passes the drivers talk about camping camp the night before and inspect them before they pass.

2 - easy

Simple vortices with obvious passages. Some maneuvers may need to be done, but the rocks and waves are easily avoided.

If you have been sleeping on the boat after lunch, you may be splashing into a river of second difficulty.

Small waves, few rocks that I avoid easily, very small stoppers, counter currents, etc. appear. Protect your book and your camera and have fun.

5 - experienced

Large prolonged or very strong vortices with obstacles that may put the rope at risk. Steep drops of low height, difficult, complicated routes and obstacles that can not be avoided.

The excursion to rafting in rivers of this difficulty is in itself an adventure. It requires very good preparation on a route with very large rocks, with dangerous currents, with steep falls in small or big waterfalls and large waves like mountains.

It is necessary to inspect the passage from the bank and require precise handling with minimum margin of error.

Successful crossing for each of these passes will surely cause excitement and applause.

3 - Medium

Dines with moderate and variable waves that can stutter an open canoe.Avoiding them difficult. Required: complex maneuvers in fast currents, good control of the boat in narrow passes. You need continuous observation ahead.

You can listen to this river. You can meet small waterfalls, big rocks, large waves, strong counter-currents, large stoppers.

With the required attention, the crews on a rafting boat have no problem, but many have been heard for the careless.

In good river maps these passages are marked and depicted.
