Abstract: The fans flooded one of spreading shapes that formed as a result of the availability of several factors, including tectonic, climate, topography, hydrology, and represents the fan one of these shapes formed in the southeastern part of Iraq, at the feet of the Iranian hills, and occupied space (1608.74) km2 and are all located inside the Iraqi border and within the province of Maysan, either her pelvis area reached (3582.87)km2 and the Association located within the Iranian border. A stronomicall Diwearege fan located between latitudes (31°40,56 - 32°10.41) north and the to the longitudes (47?18.15 - 47?51.39) east. The study aims to find out the main geomorphological and hydrological characteristics in the fan alluvial configurations, as well as to detect and track the inception stages of formation and evolution, through the study of their properties spreading, in addition to studying the water basin, which represents the main source of deposits. The use of geographic information systems (GIS) and remote sensing (RS) in the interpretation and analysis of visual and satellite digital elevation model (DEM). To get maps and geological structures of sin and maps of the surface, including the slope and direction and morphometric maps of water basins and land cover classification. And that helped to draw a geomorphological map of the fan. Through the relationship between the factors and processes geomorphological problem of the appearance of the ground and geomorphological units associated with them.The study found that the tectonic factor in the role originated fan where study area is located between two unstable tectonic. As well as the role of climate change in the growth and development of the fan, where grown and developed fan on the basis of four stages was during the era of Albulallostosen, as well as the worker hydrological and goal Basin propeller role in the growth and development of the fan through what moves them from the sediment through the rain periods, as well as the role of the worker hydrological in the evolution of the fan through the course of the river has changed and thus increase the fan area and change the geometry of her, as well as its role in increasing the thickness of the fan through the distribution of secondary points deposition on the surface of the fan, especially in parts of the lower ones.It turns out that the geomorphological processes active role on the roof of the fan and a private water erosion, as characterized by three types of erosion are Sheet and Rill and Gullies and this is due to the floods that have hit the fan.The study found that there are four varieties of shapes geomorphological on the surface of the fan, and that most of these forms the rule is problematic with watery origin precipitation, but the problem with the water origin erosion.It was found by classifying land cover fan Diwearege that there are six categories, namely, (barren land, covers are salinizaion, water cover, vegetation, bogs, agricultural land). An evaluation of the fan in accordance with the appropriate and reactivity ground it includes four varieties of appropriate as well as four levels of the earth's susceptibility which is almost identical with Aedha and that most of these categories are valid to agricultural investment and found during the study that the fan is exposed to various degrees of environmental risk, especially floods which are exposed in wet seasons.Especially the lower parts of the fan.Show that can be harvested sources on the surface of Ruha to control floods and to take advantage of this water in agriculture and various purposes. The study conclusions and recommendations and a list of sources and Savior in English concluded.

Abstract: This study is aimed to assist. The aquatic resources in Wadi Warazan Basin in the Republic of Yemen in order to estimate the water balance with regard to the natural resources and the way of usage in the different fields of activities.The importance of this study depends on the fact that wadi Warazan Basin which is (412)Km2 is one of the most fertile a agricultural areas, moreover area it is regarded to be a tourism area. The second thing is that the basin is more close to Taiz city which suffers at the present from water shortage.The final results of the study show that : 1 - The most rainy seasons are spring and summer especially, in some few days during the rain season. The most rainy month is August (14.8%) of the total rain while December is regarded to be the lesser rainy month (0.7%). The rainfall estimations during (44) years is about (346 - 875.8)mm. 2 - The annual aquatic in Wadi Warazan Basin ts about (241 349 600)m33 - The ground water runoff increases during autumn, because it occurs after the rain season, where there are many quantities of the ram underground. In contrast, other months of the year has less drainage.4 - The armual drainage which is (3492)m3 per hour varies in (193.6%) because of it's close relation with rainfall. 5 - The (165.59)mm out of the total annual rainfall is found to a wasted aquatic quantities as a result of evaporation.6 - The Absence of specific channels, which leads to increase the evaporation rate in the valley. In addition the pools which fonned at the sides of the valley represented a suitable environments for transfer various diseases such as Schistosomiasis (Belhars) and Malaria diseases. 7 - The deviation factor of Wadi Warazan shows the variation in the compactness of their rocks, so the evaporation rate of ground water runoff produced as a result of the expansion of the area exposed to the sun light.Moreover barriers and folts at the long side are an important factors for ground water recharge.8 - The present consumption of the ground water appears to be in the higher rocky aquatic layer and the volcanic aquatic rocky layer third layer (Tawila Sandstone) seems to be unconsumed because it's (600)m deep.9 - The ground water is affected by the increasing number of wells.10 - The aquatic basin net work appear to be having a high density of valleys number about (1.05)/Km2 which affects the surface flow that makes floods danger is probable.11 - It seems that the aquatic basin resources may become unable to met the increasing demand of the area and Taiz city as regarded to be an alternative to solve the city water supply problem. Moreover, the rising of the population in the basin.

Abstract: Study of climate in Basrah and its impact on Asthma and other diseases of the respiratory system have revealed the following : - 1. Climate is the most effective factor in the study. Rise of temperature, increase of evaporation and the little humidity content in soil because of the little rainfall make it possible for the wind, particularly north and northwestly wind that is dominant in the area under study, to carry the decomposed particles of soil. This is particularly true in case of the alleviatory plain which constitutes a %50 of the area of the governorate. This area is characterized by being generally plain from the north to the south and that makes it easy for the wind to blow from it. These factors greatly affect the soil in many places in the governorate; especially its western part and the unused lands in the alleviatory plain because of lack of agriculture and of natural plants which protect soil. Because of all these reasons, dust increases in the area under study.2. Areas outside the range of the study have obvious effect on carrying the particles of soil from the surrounding governorates like Thi Qar and Muthana. Thi Qar, in particular, witnesses repeated dust storms. This, in turn, increases the amount of dust in the western part of the area under study. Most of the lands in these governorates are arid and dust coming from them dominates when northwestly wind blows. Dust may come from the deserts in the neighboring countries such as the Arab Peninsula, the great African desert, sham desert and Sinai. Increased iron in the dust of the area under study is brought by the dust storms coming from the neighboring countries to the governorate. These are also other factors that increase asthma and other diseases of sensitivity in the respiratory system.3. Dust increases in summer because of rise of temperature. Variation of temperature during the day leads to prevalence of dust. Also, currents that carry dust are made, more upwards and draw the dust particles from their sources. Therefore, dust prevails in the governorate is the afternoon when temperature is the highest during the day. 4. The water surface (marshes and swamps) in the eastern part of the governorate that occupy big area (3182 Km2) of the land during flood decrease the rate of asthma and other sensitivity diseases of the respiratory system in the towns and municipalities of the governorate such as Qurna and Mediana where these surfaces become places for settling dust and soil down. This is contrary to the case is the western part of the governorate where there are no such water surfaces. But, sometimes, these water surfaces have negative impact on the population in the governorate when temperature rises and humidity increases during summer and the weather becomes very tiring especially when the wind is still. The area under study is affected by the Arabian Gulf when the south easterly wind that is filled with humidity blows during summer. Because of this wind, patients of asthma, in particular, suffer repeated symptoms of the diseases.5. The rate of the diseases under study increases in the governorate in : a. Spring because of the existence of pollen and residue of the insecticide and fertilizers in air. b. Autumn in comparison to summer because of rising in temperature and increase of humidity in the atmosphere. c. Winter because of the low temperature and the high relative humidity.d. The many periods of heat rise in summer.6. Man contributed a lot to the increase of rate of diseases of the respiratory system in the area under study particularly after 1990. The year 1991 witnessed the highest rate of dust storms. Soil was very highly decomposed because of the movements of the explosives that were used, the different soil barriers that were made and man’s wrong practices in agriculture and grazing. Man, also, does not follow the appropriate means to stop sand dunes that reach many forms, factories and roads.7.Means of transportation in most areas of the governorate cause increase of still and moving dust because they are usually not good for movement and transportation. Any movement of these means causes dust. Besides, means of transportation release different dangerous pollutants that negatively affect the respiratory system.8. Petroleum refineries, electricity power stations, flour mills and ice factories are located near the population areas. This means that little care is given to the palming of the governorate. These establishments are also, reasons of such diseases. 9. Basrah, particularly recently, is exposed to dust because of the little green area in and around it. Construction processes reduce such areas that work to refresh and refine air. It is, therefore, very necessary to full the empty spaces with trees, to take care of private and public gardens and to clean roads and allocate specific places for gar bage. Besides, old wet houses in some places in the governorate contribute to increasing the diseases under study.10. Wet salty lands in Basrah governorate are considered as a type of desertification that pollutes air with salt and diminishes many lands that are fit for forming. 11. All the above mentioned reasons raise the number of patients of asthma and other sensitivity diseases of the respiratory system. The total number of such patients was during the time of the study as following : 85320 patients of sensitivity diseases and 119366 patients of asthma
