تزداد الحاجة إلى الحفاظ على المياه مع ندرة الموارد. إن الخطوة الأكثر أهمية لإدارة هذا المورد هي تقدير جريان مستجمعات المياه. إن جريان المياه وهطول الأمطار هما المصدران الرئيسيان اللذان يحافظان على المياه الجوفية ويعيدان تزويدها في فصل الشتاء. تم محاكاة جريان المياه السطحية لمنطقة الدراسة من خلال تقنية رقم منحنى خدمة الحفاظ على التربة (SCS-CN) المدمجة في نظام المعلومات الجغرافية (GIS)، اذ أظهرت نتائج البحث عن ع

The valley Dwiridj of drainage basins task that lies east of Iraq and thus we have in this study the application of tow models athletes on the three basins of the valley to get Mor e values accurate to Estimate the volume of runoff and peak discharge and time climax and through the use of Technology remote sensing (GIS),has been show through the application of both models, that the maximum value for the amount of Dwiridj valley of (1052/m3/s) According to Equation (SCS-CN) and about (1370.2/m3/s)by approach (GIUH) that difference is the amount of discharge to the Equation (SCS-CN) ar not accurate as(GIUH) approaches Equation ecalling the results of the Field ces Department of damand reservoirs that the volume of runoff to the valley wase

The research risk of flooding on six water basins located in the eastern part of the western plateau, reached total area of the basin (22,998.9 km 2), has reached all the Basin area (basin to time 7056.1 km2 basin by 3585 km 2, Bath Alheiazi 6404 km 2, Abu beasts 544.1 km2 basin Abu Shannan 144.6 km 2, Bath Valley Faraj 5265.1 km 2), where it was specifically spatial degree of this risk by studying some of the hydrological basin transactions directly related to operations spate runoff study area and the occurrence of flood risks on the surface of ponds.

تهدف الدراسة إلى دراسة وتخلي الخصائص الهيدرولوجية للحوض مثل تقدير حجم الجريان السطحي وزمن التركيز وسرعة الجيريان ومعامل الفيضان وعمق الجريان وزمن الوصول واخيرا اتجاه الجريان

Dry environment study forms an important part in the field of applies geomorphology for
the wide rang of its lands which form most of the world, homeland, and Iraqi lands specially,
and what these lands include of scientific cases which needs to be searched and investigated.
They include rocks, land shapes, water supplements, its ancient soil and its active diggings are
all signs of the environment changes and effects that these lands under take over time, with
continuous remains of its features of characteristics under geo morphological dry
circumstances which works to slow change average, when the geomorphologic fearers varies
in this environment and what it contain of important economical resource. As to participl

تُعدّ الملاءمة المكانية لحصاد المياه من الموضوعات الجغرافية التطبيقية المهمة، إذ تهتم بتحديد أنسب المواقع جغرافيًا لإنشاء منشآت حصاد المياه اعتمادًا على مجموعة من العوامل الطبيعية والبيئية، مثل التضاريس، التربة، الجيولوجيا، الغطاء الأرضي، وشبكة التصريف المائي، بما يسهم في استغلال مياه الأمطار والسيول بصورة فعّالة ومستدامة. هدفت هذه الدراسة إلى تطوير نموذج مكاني متكامل لتحديد المناطق ذات الأولوية لاختي

Free water surface constructed wetlands (FSCWs) can be used to complement conventional waste water treatment but removal efficiencies are often limited by a high ratio of water volume to biofilm surface area (i.e. high water depth). Floating treatment wetlands (FTWs) consist of floating matrices which can enhance the surface area available for the development of fixed microbial biofilms and provide a platform for plant growth (which can remove pollutants by uptake).  In this study the potential of FTWs for ammoniacal nitrogen (AN) removal was evaluated using experimental mesocosms operated under steady-state flow conditions with ten different treatments (two water depths, two levels of FTW mat coverage, two different plant densities and

In this work, an enhanced Photonic Crystal Fiber (PCF) based on Surface Plasmon Resonance (SPR) sensor using a sided polished structure for the detection of toxic ions Arsenic in water was designed and implemented. The SPR curve can be obtained by polishing the side of the PCF after coating the Au film on the side of the polished area, the SPR curve can be obtained. The proposed sensor has a clear SPR effect, according to the findings of the experiments. The estimated signal to Noise Ratio (SNR), sensitivity (S), resolution (R), and Figures of merit (FOM) are approaching; the SNR is 0.0125, S is 11.11 μm/RIU, the resolution is 1.8x〖10〗^(-4), and the FOM is 13.88 for Single-mode Fiber- Photonic Crystal Fiber- single mode Fiber (SMF-P
