Abstract:
The study area is located in the western part of Iraq within the
province of Anbar, with an area of (138,288) km2, equivalent to (31.8)
of the total area of Iraq, amounting to (434,128) km2. It is located
astronomically between the two latitude circles (33, 33.6) and (30, 31,
34) north and between Longitude (41,12 ° 35) and (40-18 ° 42 °) east.
The total area of the district is (5701.5) km2 and constitutes (4) % of
the governorate area. The region is classified within the arid and
semi-arid climatic regions that are characterized by low rainfall and a
lack of permanent water sources. Therefore, groundwater is an important
source on which the investment process depends.
The natural factors also affected the hydrological characteristics of
groundwater in the region due to the presence of geological formations
whose rocks contain a high percentage of gypsum and lime that dissolve
in water quickly. High temperatures, low rainfall and increased
evaporation are other factors which affected the efficiency of
groundwater and its spatial distribution in the region. The
geomorphological characteristics also affected the change in the path of
groundwater movement in different directions and the variation of its
depths.
Underground water resources in the study area vary spatially by
studying the area and taking (50) samples of wells. They are located
within two reservoirs, namely the Euphrates underground reservoir, Anah
and Sheikh Alas reservoir which contain a group of underground
reservoirs. They depend for their feeding on several sources, foremost
of which is rain and surface water. The depths of the wells were
(150-30) m.
The constant groundwater level ranged between (9-95) meters and the
variable level reached (0.5-28) meters, while the productivity of the
wells reached (0.5- 45) liters / second. The direction of groundwater
movement is from the south and southwest towards the north and northeast
according to its hydraulic inclination, with some secondary directions
due to different surface appearances.
The study of spatial and temporal analysis of the physical and
chemical properties of groundwater in the study area shows that the
properties of ions varied between the dry and wet seasons. The reason
for this variation is due to the influence of a group of factors. The
most important of which is the natural factor represented by climatic
conditions as well as the human factor represented by agricultural
activity, the extent of using chemical fertilizers and the amount of
water withdrawn from ground wells in the study area.
After comparing the results of the analysis with international and
local standards, it was found that they are not suitable for human
drinking and industrial purposes at present. They can be used for
irrigation purposes if there is a good soil and water management. They
are also suitable for various types of animals. The study showed that
the agricultural activity took first place in the amount of available
groundwater, and the spatial modeling of the qualitative characteristics
of water proved that most of the study area is suitable for different
human uses, especially agricultural and animal use.
In light of these data, aspects of groundwater investment, its problems
and future prospects in the study area were studied. One of the most
important aspects of its investment in the region is agricultural
investment, which constitutes the largest percentage about (91.8)%
compared to other uses (for human drinking, animal drinking, industrial
purposes, building and constructions).
It is not a secret that there are some problems that groundwater
suffers from, represented by the problem of low productivity, the
problem of pollution, the problem of lack of interest in wells, as well
as other problems. These problems activates the research to present
solutions and proposals for the development of groundwater in the study
area by improving water quality and increasing the feeding of
groundwater (water harvesting), as well as rationing water consumption,
addressing the problem of pollution, taking care of wells and
maintaining them. Using modern technologies as well as other solutions
and proposals aimed at developing the investment of groundwater in the
region in the future.
