الموازنة المائية المناخية في شمال العراق

الملخص EN

The quantitative relationship between the falling of rain and the amount of evaporation/ transpiration to know the hydrous superfluity or shortage is called hydrous climatic balancing.

Balancing is mainly influenced by some climatic factors, in particular the amount of falling and temperature through which the amount of evaporation is known mathematically.

The need of agricultural crops for water is mostly connected to the amount of hydrous losses through evaporation/ transpiration, which can be compensated through falling or irrigation.

In order to improve the agricultural production and to be able to provide food for people on one side, and to achieve economic growth and increase the national income on the other side, large areas of arable lands should be utilized, and this requires supplying additional amounts of fresh water to be used in irrigation.

Therefore, the research studies the seasonal distribution of the superfluity and shortage in the zone of the study in order to know the winter and summer crops' needs for water, and the possibility of supplying enough water for the land in case of future expansion of planted areas.

The research attained conclusions and solutions the researcher considers useful to this zone of Iraq.
