Building the dams

7. Dams are small barriers across the stream. Dams hold up the water, so that the water of the stream rises. In this way, the water of the stream overflows into the low- lying land.

It is best to have concrete dams.
They cost more, but they last longer.
The good harvests of the following years will pay for the dams.
The technician will tell you where to build your dams.

Building the dams

8. When the dam is built, dig irrigation channels around the edges of the field.

These are called main Irrigation channels. Dig also, right through the middle of the field, the main drain.

The water flow starts from the dam.
It goes into the main irrigation channels.
It floods the rice field.
It goes out of the rice field into the main drain, which is the channel for the outflow of the water.
