السدود هي انشاءات هندسيه تقام فوق وادي او منخفض والهدف منها حجز المياه والسدود هي اقدم المنشأة المائية التي تساهم في تنمية موارد المياه ويتم الاستفادة منها في الري والزراعة والثروة الحيوانية وفي الصناعة والسدود لها أهمية كبيرة في عمان فهي تحمي من الفيضانات و الامطار الغزيرة تتحمل السدود المياه و الطمي فتترسب مما يمنع تدفقها الى المصب مما يؤدي الى تأكل مجرى النهر بتزايد الرواسب المتراكمة في الخزانات والسدود ويختلف معدل الترسبات من سد الى اخر مما يؤدي الى اخذ مساحات في الخزان ويمنع حفظ المياه في السد ويؤدي الى انخفاض المياه وتأثر الرواسب على كفائه السدود وبالتالي السد يحتاج الى صيانه والتخلص من هذه الرواسب صيانه السدود مكلفه وصيانتها متعبه .

Dams are construction engineering are held above the valley or low and aim water reserve and dams is the oldest hydro facility, which contribute to water resources development and are utilized in irrigation, agriculture, livestock, industry, dams are of great importance in Amman. It protects from flooding and heavy rains bore dam water and silt Vtaatersb which prevents flow to the estuary leading to erosion downstream increasing accumulated sediment in the reservoirs and dams varies deposits rate from dam to another, leading to taking space in the tank and prevents water conservation in the dam and leads to low water and affected sediment on the efficiency of the dams and therefore the dam maintenance needs to get rid of these sediments maintenance of dams and expensive maintenance tiring.

Dams are geometric constructions is held above the valley, or lower the dams and water block is the oldest established water to water resources development and utilization in irrigation, agriculture and animal husbandry in industry, are of great importance in Oman are protected from floods and heavy rain water and silt dam shoulder which prevents the flow of Fttrsb to the downstream river course leading to eat the increasing accumulated sediments of reservoirs and dams The rate of deposition of the bridge to another thereby keeping spaces in the reservoir and dam, water conservation and water decrease the sediment on the efficiency of dams thus the dam needs maintenance and disposal of sludge dam maintenance of expensive and tedious.
