Hydrological study of groundwater and its appropriateness for irrigation

Abstract EN

Irrigation in most countries represents the largest share of all water use.

Groundwater is the main water resource after the water of the Nile River in Egypt.

The water situation in the future is not optimistic due to the economic development, the increase in population growth and the increase in the agricultural area, especially after the completion of the construction of Ethiopian Renaissance Dam, so suitable alternatives must be provided for irrigation water.

This paper presents a hydrological study on groundwater for use in irrigation in Assiut, Upper Egypt, so that alternatives can be provided to the Nile River for water used for irrigation purposes and appropriate uses.

The experiments were performed using an experimental form created to achieve the purpose of the study.

The model consisted of a cascade aerator and a sand filter.

packed bed filter was added to be filled with some media before the sand filter.

The media that were used in the study were plastic balls (80 mm), gravel (5-8 mm) and coarse gravel (15-30 mm).

The results showed that use of water leads to improving the efficiency of groundwater and thus making it suitable for irrigation purposes.

Using this model with the addition of the media used in this study, groundwater was improved by up to 90% and therefore it could be used for irrigation.

Finally, it is believed that the results of this study are useful in hydrological studies of groundwater for conditions similar to the ones under which this study was conducted.
