Population in these areas and along waterways often are dry agriculture practice together. Population density in order to ensure their survival is high, it retains a culture of rebellion, excessive or inadequate systems for the development of first use of the river's water.
These systems are currently two main types of culture.

Also, stop solution is not far points to the issues involved in irrigation, especially when one of them serious damage or an excuse, salinization, water, capillarity as soggy, and then the desired depth of salt, the salt evaporation through a prima facie case to settle.
