Analyzing Rivers for Whitewater Kayaking

Whitewater kayaking is an exciting adventure sport that every paddler would love to experience, once in their life. Although, one must realize that whitewater kayaking is often a sport for hardcore kayakers, and beginners have to gain ample expertise and experience to live the thrill.

Whitewater kayaking requires meticulous planning and accurate execution of the plan. The first step in whitewater kayaking is analyzing the river. Rivers are classified according to their speed of flow, waves and the course they follow. The International Scale of River Difficulty is a scale that classifies rivers into different grades depending upon their level of difficulty. The grades range from Grade I to Grade VI.

Following are the Grade-wise classification of the river characteristics.

Grade I – Rivers that fall under Grade I category are calm and easy to paddle through. They are virtually free of any obstacles and have a clear passage.

Grade II – Rivers flow moderately fast but are free of obstacles. To attempt kayaking in these rivers would require a fairly experienced kayaker.

Grade III – Rivers flow faster with numerous, irregular waves. Only an experienced paddler can maneuver through the narrow passages.

Grade IV – High, irregular waves coupled with narrow and rocky passage, reserve Grade IV rivers only for paddlers with excellent skills to maneuver their kayaks. Good quality equipments and powerful paddling skills are necessary to tame Grade IV rivers.

Grade VGrade V Rivers are extremely difficult. Violent currents, steep gradients, dangerous passage with rocky obstacles, high waves, boiling eddies are the river characteristics.

Grade VI – Rivers are highly untamable and pose a serious threat to life.

These numerical grades are often followed by a plus (+) or a minus (-) to indicate if a river is inclined towards the higher or lower end of difficulty. There are specific grading systems in USA, India, Australia and New Zealand. They are more or less based on the International Scale of River Difficulty.

 

Rivers are very unpredictable. Thus, even though the rivers are classified into these Grades, it is essential to study the river before kayaking. River conditions are likely to change seasonally, so it is better to check with the locals, in advance. Increase in the water level makes rapids more difficult. In case of floods, even Grade II rivers can be fatal.

Similarly, heavy tides can cause a river to flow uphill. For whitewater kayaking, selecting the right path helps in averting difficulties. Reading a river or studying river patterns take time and years of experience. Beginner paddlers often learn to read the rivers from other experienced paddlers.
