APPLICATION OF ENVIRONMENTAL ISOTOPES TECHNIQUE IN GROUNDWATER RECHARGE WITHIN MULLUSA CARBONATE AQUIFER-WEST IRAQ
Bayan
M. Hussien
This paper applies environmental isotope techniques to interpret recharge mechanisms of Mullusa aquifer (East Rutba ) and offers an environmental isotope view . Mullusa aquifer is of major importance for the water supply of Rutba region in particular of increasing demand of water resources and sustainability assessment in the future. The traditional hydro chemical and hydraulic interpretation show same phenomenon of groundwater source and interconnection, which may need advance isotope technique to define the exact actual origin of recharge water, using carbon-14 and tritium dating . Based on the isotope analysis of deuterium, oxygen-18, tritium, carbon-13 and carbon-14, the recharge of the carbonate aquifer is mainly from direct infiltration of atmospheric water (Rainfalls and / or runoff ) originated to Indian low pressure depression through exposure outcrops within Hauran catchments area of ( 600-740 )m.asl due to south and southwest Rutba town . The isotope compositions also show that the groundwater is a mixture of an old groundwater with modern recharge in the areas adjacent to Rutba . The maximum percentage of modern water ( pMC % ) is 71% (29% ancient ),which was usually found at the intensively infiltration zones of porous media and / or fractured areas ( Hauran valley ), while the minimum percentage of modern water is 10% (90 % ancient ), which was found at discharge zones as fossil water with very poor replenishment mechanism. Also, this research shed light on the paleo-hydrologic setting ,that may control the recharge mechanism using 14C dating for each site . Finally, the important detected result is that Mullusa aquifer in Dhabaa site (pumping station of multi boreholes system) stored ancient fossil water with slow and limited recharge. The reachable transit time of replenishment is of about 29000 years calculated by traditional hydrogeologic technique, which is closed to the value of residence time that detected by14C dating (31500 years ), so that it is necessary to regulate the production of groundwater according to active plan.

Soil Salinity is one of the most important considerations for monitoring soil degradation and continued desertification that threat some regions in Iraq. Remote sensing techniques and GIS operations have been used for multidate image processing to detect and monitor the history changes of soil in the western part of Mesopotamian plain. The aim of this research is to assign the appropriate and effective image processing techniques to be implemented for monitoring, and then to evaluate soil salinity in the term of the corresponding spectral response in the best spectral band. Landsat MSS, TM, and ETM images for the periods 1972, 1990, and 2000 respectively have been selected, as well as ancillary data of the available salinity field measurements have been used. ERDAS (8.5), ENVI (3.6), and ArcGIS (9.2) softwares have been used for the purpose of digital processing, creation of information layers, integration, and statistical correlation. It is concluded that created image brightness and salinity indices indicate the increasing of salt affected soil during the mentioned period of images. And these image indices have the highest correlation coefficient with Mid-IR band. A predictive equation is established to estimate soil salinity in the term of spectral response of Landsat images; the effective relationship is specified at the value above 28 ds/m of Electrical Conductivity (EC), and the obtained correlation coefficient 87 % reaches to 95% when EC values of soil increase to more than 70 dS/m.

H. Kamel
Water resources is one of the most important criteria for societies building and their development. Evaluation, planning, and management of water resources are rasid to be one of important subjects in the humans life, particularly in arid and semiarid region like Iraqi western desert, since precipitation is extremely limited and spatially distributed, with poorly available ground water supply. Rainwater harvesting is defined as a method for inducing, collecting, storing and conserving local surface runoff for agriculture in arid and semi-arid regions. This paper examines the effects of different variables on the water harvesting in Iraqi western desert like catchments area, bed slope geometric and topographic properties. By using unit hydrograph theory, the volume of harvesting water was calculated, and by frequency and statistical analysis to determine maximum harvesting water for return period (5, 10, 25) years, with geographic information system (GIS) we make a number of maps for the region of optimum harvesting water which can use for design of agriculture and irrigation project in Iraqi western desert. The study show there is a potential ability for using the harvesting water in Iraqi western desert.

Abstract: Aeolian deposits and dust storms have wide geographic distribution in Iraq and northeastern part of Arabian Gulf, this phenomenon get an overtaken interest owing to their environmental impacts on economic activity and human health. Most of aeolian deposits are in the form of dunes. Burchan is the dominant type of sand dunes at Najaf area initiated by the uni-directional northwesterly winds action, nevertheless; dome-shaped and elongated types of dune (Fixed dune) were also reported at Nasiriyia and Samawa. Dust storm phenomena are common in central and southern Iraq and northwest Arabian Gulf. Aeolian deposits are concentrated south of Baghdad, Karbula, Najaf, Nasiriya, Basrah as well as Kuwait. The major source area of dust is Baher el-Najaf sands, and ancient sediments of Dibidbba, Injana, and Rutba Formations cropping out of western Iraq, as well as, alluvial deposit of Tigris and Euphrates Rivers. The mineralogical analysis indicated higher percentage of light minerals in comparison with heavy one. Furthermore, the heavy and light mineral assemblages of the studied sand dunes proved that their materials have been derived from rocks cropping near by, as well as, the Tigris- Euphrates alluvial deposits contribute to the source materials. The mean values for Pb, Cd, Fe, Cu, and Ni heavy metals in dust fall over Thi-Qar governorate are:149, 8, 7569, 72 and 212 ppm respectively. These values indicate that vehicles engines besides agricultural activities form major sources of these metals

Abstract: Less than 50% of leaching requirement application was chosen in order to reduce the negative offect of saline water in irrigation forming by conducting an experiment on clay loam soil, three qualities of water were : river water (Ec 1.4, SAR 2) saline well water ( Ec 4.99 ds/m, SAR 7.5), and mixed water with 1:1 ratio from both above mentioned waters ( Ec 3.1 ds/m, SAR 5), to irrigate corn plants during fall season (2006). The (50% leaching requirements) for each quality of used waters was calculated based on equation mentioned in FAO irrigation water quality index). Were the values (5,15,30%) for each of ( river water, mixed water, saline well water) respectively. Irrigation practices were applied by using a net of main and sub-main pipes, was designed for this purpose. Soil moisture was monitored by using netron probe device. The results showed that the use of mixed and saline water to Irrigate corn plants resulted in significant increase in soil surface (0-0.40 m) salinity which was 1.4 and 1.8 times more than pre planting. A significant increases in modulous ofrupture in soil irrigation with saline water, by 68% and a significant decreases in mean weight diameter by 33% compared with river water. Significant reduction by (23%) in relative yield of corn compared with river water, on the other hand no significant reduction was shown between mixed and river water on their effect on modulus of rupture and mean weight diameter and relative yield. It was calculated that the addition of 50% of minimum leaching fraction was not adequate for maintaining salt balance, and the importance of increasing saline water application, especially is fine-texturel soil like study soil.

Abstract The study was conducted for determining the effect of application amount and pattern of leaching requirement for corn (zea mays L.) in fall season in 2007, in the soil and water resources center research station - Ministry of science and Technology. The experimental design was factorial complete randomize block design in three replicates. The main factors were three:- i. Two quality of irrigation water. ii. Two level of leaching requirement application. iii. Two pattern of leaching requirement. Soil chemical characteristics and yield of corn was monitored as affected by irrigation with saline water. Results indicated increasing in values for salinity of soil saturation paste solution for depth (0 – 60 cm) to values 3.7 time in irrigation with saline water without application of leaching requirement comparing with soil irrigated with river water. Using two levels (20 , 40 %) of leaching requirement caused reduction in the values of soil salinity to 30% and 43% comparing with treatment without leaching requirement respectively. Minimum redaction in the yield 14% was occurred in using the second pattern (application of leaching requirement after 50 days from the first application) with 40% level comparing with the yield of irrigation with river water.

Abstract: This study was conducted at fields of Al-Majd agricultural company which located between falluga and thirthar at al saqlawia / Al-Anbar government, to study the effect of using different irrigation methods (flood - drip - sprinkler) irrigation to using its gypsiferous soils with irrigation water class C3S1, to know the effect of this irrigation methods in some soil morphological and physical properties . After semi detail survey, four positions were pointed that were different in agricultural using nature for three years as following:P1 virgin soil (B), P2 land which used for cereals with flood irrigation method (FW3), P3 land which used for cereals with sprinkler irrigation method (SW3) and P4 land which used for vegetable with drip irrigation method (DV3).These four pedons were described morphologically then soil samples were taken from each horizon to analysis some physical properties. The results showed that following: 1. The thickness of surface horizons for cultivated site increased in comparison with uncultivated soil from 18cm to 25 cm. 2. The soil structure grade was weak in all pedon’s , especially at soil which was under the flood irrigation 3. There is no significant effect for irrigation method on particle density at all horizons, this property data was showed decreasing in its value with increasing soil content of gypsum, but the bulk density was effected by irrigation practice significantly, it was increased 5.4%, 10.0% and 13.9%as mean for treatments DV3, SW3 and FW3 respectively. 4. There is significant effect for irrigation method on studied soil water properties (field capacity, wilting point and available water).Using of drip irrigation method was showed higher increasing in these properties in comparison with other irrigation methods. 5. Soil penetration resistance was decreased 3.9% in farming lands without significant different in comparison with virgin land, and lower value was pointed at Ap horizon for DV3 treatment reached 2.6 kg.cm-2 while the same horizon for SW3 treatment was showed the higher value 3.1 kg.cm-2.

Abstract: A field experiment was carried out at Alsaqlwiyah town/fallujah/AL-Anbar Governorate, on a clay sandy soil to study partitioning of phosphatic fertilizer and water stress on growth and product characteristic of maize (Zea mays L.). The treatment combinations were two levels of phosphorous fertilizer, one dose and three doses application with three levels of water stress, non – stressed, stress at early growth and stress at flowering initiation stage arranged with factorial experiment using R.C.B.D design with three replicates. The results concluded that phosphorous doses significantly increased leaf area and individual plant yield. Water stress significantly decreased leaf area, plant height, individual plant yield and 100 grain weight. The application of three doses of phosphorus was superior than one dose. The plants that underwent water stress at early growth stage were more impacted than been at flowering stage. It could be concluded that phosphorus had potentiality to increase stressed-crop yield, whereas the initiation of phosphorus partitioning three times X water stress at pre-flowering improved individual crop yield 191.5 gm more than one time without partitioning X early water stress 182 gm. The integrated management of maize is very important to tolerate stressed environment, because of being difficult to apply phosphorus incorporatedly into soil, due to loss large accounts soil fixation and lowering of plant uptake.Therefore,it has to partition with plant growth stages to increase its efficiency. That is necessary to assist increase of extracting of latent abilities of processes which had important role for increasing water economics, production and productivity. These will emphasize properly scientific decisions for managing these operations.

Abstract Many research aim at benefiting from the solid wastes of houses , grocers and fruit shops by converting there wastes to organic fertilizers using biological techniques to decompose the waste which, then, will be used as nutrition to agricultural lands. The fermented organic fertilizer increases the productivity of heavy crops and it erades the environmental pollution problem because it is discarded in great amounts annually. The objective of the present research was to study the influential factors in the decomposition of wastes to gain the optimal conditions that increase the velocity of decomposition and the amounts of nitrogen compounds that attain it through the use of some organisms to top-up there secondary product values to be weal as organic fertilizer. Solid wastes of agricultural products and kitchens have been collected from Ramadi city (Taameem Quarter). An initial information list has been designed and distributed in to 100 vegetable shop and 1000 houses and flats. The results have shown that the average of waste weight from agricultural sources from families was 2 kg / home / day and 10 kg /shop /day. Treatments were prepared by forming a mixture of waste with rock phosphate (RP) P%8, with mixing percentages 0 and 30%, Nitrogen quantity in urea fertilizer was modified from 0, 0.24% urea . Decomposition was carried out under aerial and unaerial conditions. Two types of aerial bacteria Azomonas and Streptomycetes were used .The sample was putin plastic cups of 5 kg weight solid phase . Humidity was demermined at 60%. All treatments were subjected to the specified conditions in the study for two months. Results of analyzing the decomposition products show that:- All treatments have undergone thermal changes between 22 - 23 Co except the treatment under the unaeral conditions which recorded a noticeable rise to reach its climax at the 5th and 6th weeks with an average between 60 – 64 Co . The smallest pH 5.18 was recorded in decomposition treatments under unaerial conditions followed by treatments using Azomonas bacteria with 6.61 average. Moreover, mixing urea decreased pH to an average of 6.43. The total carbon quantity significantly decreased to 53.8% (182 g. C / kg) before decomposition in the treatments with 30% RP mixing using Azomonas and urea 0.24% . The was a significant increase in the total nitrogen with 14.9, 19.1, 18.6 % and 27.5% percentages, using Azomonas isolate and 30% RP mixing . C:N reached its lowest levels after the decomposition in Azomonas treatments 8:1 , 12.6:1 , 9.5:1 ,14.1:1. The upheld treatment urea 0.24% and RP O% under aerid conditions showed the highest levely of humic acids which was 12.65 g/kg. The beast treatment for dissolving phosphate composition was RP 30% and urea 0.24% under unaerial conditions , or using Azomonas provided 23.2 and 22.6 g p/kg with a dissolve ratio of 82.3% and 80.1%, respectively 0f total phosphate comositions. The higest quantity of phynol was 2.24 g/kg from treatment RP 30% and urea 0% under unaerial conditions, while the lowest quantity was between 0.23 and 0.75 g/kg with the control treatments and Azomonas. The best numerical density of microbes 8.35 Log cfu/ g was achived from the use of streptomycetes bacteria.
