 My opinion about the picture is a bad scenery be an eyesore to us who see it because the flood is very disturbing society. One of them interfere with school activities. because the floods can be stuck in traffic longer than usual. Sometimes even coming late to school because of congestion is more severe. Floods that inundated the streets can make wet shoes. concentration learning can be interrupted for less comfortable with the state of wet shoes.

Can be seen from the photograph car must be careful in passing the flood because there may be a street damaged or perforated contained in there. Torrential flooding can disrupt the balance in driving. Homes affected by floods make the owner must keep goods in a safe place so as not to wet and broken by floods.

In my opinion this is caused because the public indifference about the importance of the environment and therefore we as a society to protect and preserve the environment in order to avoid flooding.

CAUSE FLOODING EVENT

Flooding occurs because of several factors as follows:

1. Blockage of the watershed or sewers

This blockage occurs because people used to throw garbage in the river. They assume that if the waste is burned, it will cause air pollution and odor. So they take shortcuts without thinking about cause and effect.

These blockages also occur due to sedimentation or precipitation that occurs downstream. This reduces the deposition of the river's ability to hold water.

2. Deforestation

Human attitude did not think long before acting, cause man to act arbitrarily on the environment. These actions may include logging which do not use selective logging system. The impact is the lack of trees to absorb water so that the water flowing uncontrollably.

3. The high rainfall

Rainfall is relatively high, causing rivers can not accommodate the volume of water that exceeds the capacity.

4. Small absorptive area

In modern times this time, the catchment area is very rare. Especially in urban areas are basically very vulnerable to flooding, given the condition of the city located in the lowlands. Just a lot of absorptive area covered by asphalt or the concrete so that water can not seep into the soil.

5. Establishment of houses along the river

People who set up home on the edge of the river, tend to reduce the width of the river. With the reduction of the width of the river, causing water to flow optimally.



IMPACT ARISING FROM ANY FLOOD

While the impact or due to flooding include the following:

1. Damage to facilities and infrastructure

Particles entering the water pooled on the wall of the building, if the walls are not able to withstand the water content of the wall will suffer cracks and eventually broken.

2. The loss of possessions

Large-scale floods in the stream was able to drag anything in its path, including possessions. Such as chairs, beds, tables, clothes, and so forth.

3. Potential casualties

This is because the water flow is too heavy, so many people were washed away.

4. Cause of germs

Diseases that can be caused, for example itching. The flood waters brought many of the germs that spread of disease is very large.

5. The destruction of agricultural areas

Flood able to submerge paddy fields. Of course this is extremely detrimental to the farmers and the country's economy to be disturbed.



HOW TO FLOOD PREVENTION

To cope with flooding, it is necessary countermeasures as follows:

1. Optimization of the river or ditch

River or ditch should be maintained and used properly. River or ditch not to landfills. Cleanliness of the water and swift currents to be monitored at all times just to observe if at any time there was a flood.

2. Prohibition of making houses along the river

Land on the outskirts of the river should not be used as residential areas. Besides causing floods, as well as public order patterns become irregular.

3. Carry out selective logging and reforestation program

A felled tree should have been replaced. Cutting down trees that have woody shoots back then planting new trees. It aims to regenerate the forest from being deforested.

4. Using a simple flood detector

To monitor for signs of flooding, we need a flood detector. The detector is made simple so that people can afford to make.
