There are three instances when crossing the river – stream:
– Song wadi, can wade pass.
– River deep stream, to swim or use the float, raft to cross.
– How to bypass bridge.
★ cores CROSSING
– Selecting the right position to cross the river: The river where the water flows slowly winding than in straight lines, but beware there are underground vortex.
– Exploration of the rapids of the river, often large shoals and easily surpassed the narrow and deep space.
– When two rivers and streams meet, we should exceed the upper part of the intersection, but must pass twice, but there is often shallow and weaker flow.
– Survey bottom rivers and streams, where many mud should not wear shoes because the shoes you may have gotten under the mud. If the gravel should wear shoes to limit slip, causing injuries, scratches …
– Note to the different speed of the flow when the obstacles encountered, the site has backwater circle.
– Search for the point can cling when needed.
– If you experience fast-flowing rivers and deep, then you should go back to the upstream, preferably where the branching of the river.
– Watch out for trees, logs, or other foreign objects drift downstream.
– Do not cross the river at sections with rocks, many trees float, water tightening, slippery …
– The mild and dry maelstrom they can pause to break point, but if deep swirling and then become dangerous, may capsized boats and drown you.
– Note to the sudden rain in the area, or the storms in the high mountains nearby, it could create unexpected flash flood, very dangerous.
Crossing rivers alone:
– Choose a wide river, shallow, little mud, no subsidence, water, empty.
– If the water is muddy river, carrying sediment, garbage, water hyacinth floating …. You used a long stick to probe the front. Move slowly, gently put sticks to probe but not rested people on sticks.
– If you have luggage, worn high on the shoulders for balance (not wearing a shoulder for easy off-balance) and not get wet, but not so tied to the people, because when necessary, can be quickly removed.
Collective River Crossing
– If the river is not very wide and long enough wires then appoint one most fit to swim, do not carry luggage, holding rope angle to the flow goes through the other side, and then rope tied to a tree or Gross rock.
– Once finished, the columns rest on this side stretched rope tied to a tree and or gross stone. Such is the grip you have a safe place to cross the river.
– The final, uncouple, tied to the same person to both pull him into computing.
– If the cord is not long enough, the entire group went in single file, in the hip straps, sticks. Healthy people are ahead or behind responders.
– Move slowly one by one, the man walked, others remain, not to take steps at once, to prevent if there is a risk of falling, the others not being dragged under.
This method can be used in places where water is quite strong, and must have 3 or more people, but do not be too crowded.
Standing in a circle, arms clinging to each other’s shoulders. The strongest stand under the upper end of the flow. When moving, so close shuffled riverbed, do not turn your feet up, the water will make your book off balance. The downside of this method is that if a person slipping and falling, can entail a two-person, damaging the structure of the team.
Using a long pole:
Find a medium diameter pole handle, length enough for people to stick together. This method for use in areas where the stream. When moving, the most powerful person at the bottom of pole, the bottom flow. Everyone has the power against the flow medium passes to the other side.
★ POOL TO SONG
If you have a deep river, wade across the river can not be, but if you know how to swim, you can swim into. But before you swim, you should note that:
– The wide river, with large water flow and high pressure is very dangerous and should not swim through.
– The width of the river often due to wider width of your eye estimation.
– Except for the athletes you are swimming or fishing, or else swimming ability of you often “fake” than you think.
– If the weather is cold, do not cross the river in the early morning and when your body is not heated.
– When the water temperature is too low (below 15 ° C) should not cross the river, whether you are a good swimmer will quickly frostbite.
– We should undress, shoe socks, pocket cloth or plastic bag and grabbed the top of a column or team.
– When swimming, you should rely to support downstream energy consuming.
– If there are people who can not swim or companion bad swim, the skilled swimmers strung across the river so that they cling to that cross the river, but the last time they will also need a good swimmer next to guidance support and escort , making them feel secure.
★ crossing the river by pontoon
To cross the river safely, with less effort, you should teach yourself the buoy. Depending on conditions and materials permit, you can do the following simple float:
Float with pants
Use a thick cloth pants with better, grabbed both tube column again, buttoned, soak the cloth swells. Hold both sides of the waistband, swung over from the back to banging into the water.
Use the trunk:
Find the dry trunk (or fresh) have good buoyancy as bamboo, banana, cotton balls, drop into the water and communication … you stick side to swim through.
Use a plastic cloth and vegetation:
If you have a plastic bag, a sheet of nylon or waterproof fabrics, then you take hyacinth (duckweed) removing the groom, dry grass, dry leaves, twigs (cork …), put into bags or apprehend column, turned into a pretty good floats to cross the river.
Use straps and wood:
Two stick tightly over 1 meter (look good buoyancy crops). Using ropes together, leaving a gap size 40-50 cm. Have you had a very good floating buoy.
Use a light or interference empty crates
– If there is an empty wooden crate light or interference, then you hug the chest and swim hard forward on two legs.
– If two or more bins, then you put together as friends or float.
Use poncho and luggage:
If you have a poncho or waterproof fabric, you make a pontoon across the river can carry a fairly heavy amount of luggage. Carry out four steps in the illustration below:
★ crossing the river by FRIENDS
When transportation needs many, many times, many, many luggage …. Or you want to float along the river … If you have the time and tools, you should play a raft sure. But this is a primitive means of transport but quite safe and comfortable.
To close a friend, first you have to choose some plants floating nature well as the bamboo-lined, wool, communication … have the same size and same type together. Use a wire rope available or forest, plus the skill and talent of the resourceful flexibility you to pair them together according to the following ways:
Bring friends into the river to the rhythm Pendulum:
When you need over and over again on a river, you can select a segment of the river brackets with the stream. Column friend angle difference to a tree (as shown). Adjustable fastener until friends thanks to water power, automatic friend-offering from this shore to the other side that you do not need to power the paddle.
Safe for river raft drifting
If you want to make a long journey by raft drifting along the river, then firstly, you climb a tall tree or a hill, far larger eye for sweeping downstream. This is essential, because it will give us an overall view of the landscape, where we will arrive.
– Should do a rudder for easy control friends. Bring a pole or paddle to paddle, avoid bumping friend, in the obstacle, the promontory, rocks …
– Listen to audio transmitted by water, it can alert you to the presence of waterfalls, rapids or obstructions … thanks hour pouring water.
– If you see the horizon cut across the river, immediately pulled raft ashore immediately, because maybe there is a high waterfall, easily broken or submerge your friends.
– When friends going away to places underground, rapids, waterfall, whirlpool turbulent region, go to the shore and climbed slowly by rope raft giong to have hit rock missed friends, caught up in the vortex or fall in rapids … you still can keep the safety of friends.
– Baggage on friends to put the cover waterproof and cinch tightly to friends, or tied to a piece of wood slightly, well, just in case if it falls off the raft, you can find easily.
– Note the wavy weird, because it may hide rocks, easily derailed Tuff your friends.
★ EXCEED RIVER BRIDGE IN SPRING
In fact, only when you plan to stay long in the new area to build a bridge, otherwise you find the natural bridge from the trees fallen across the stream (in tropical forests very much) to pass stream.
To build a bridge, you should know some essentials such as:
– The width of the stream
– The depth and flow of water
– Current status of stream bottom
– The situation on both sides …
Usually, you only need to make a monkey bridge, simply by choosing a tree that grows along streams inclined, just enough length to width of the stream, he traveled all the branches to entangle. So you’ve got a convenient bridge.
You can also design a V-rope bridge to cross the gorge, abyss … very convenient. This type is matched by demand from 3-5 to rope, sure, Stretch V-shaped, fixed together using smaller ropes. Largest rope in the middle, below the other fibers, used to go. The other yarn tension is higher, as handrails and railing.
