奥摩斯坝位于美国圣安东尼奥河一条名叫奥摩斯科里克的支流上,在得克萨斯州圣安东尼奥市区东北方向上,距市中心约8.9公里。该坝建造于1925～1927年。从此,圣安东尼奥市的人口从16.1万增加到78.5万人,伯哈尔县的人口从20.2万增加到98.7万人。奥摩斯坝集流区由于受墨西哥湾不稳定气团向东北方向移动的影响,从而出现超过100年一遇的大暴雨,如1921年和1972年的暴雨即是。暴雨面积有时超过31080平方公里。 1973年研究发现,用几次复盖全集水区暴雨进行的洪水演算,都将不同程度地使大坝漫顶,致使大坝承受的应力超过了原设计允许的极限,安全系数减小以致结构破坏。
Omoos Dam is located on the tributary of the United States San Antonio River called the Aomorsk Rick in the northeast of San Antonio, Texas, about 8.9 km from the city center. The dam was built in 1925-1927. Since then, the population of San Antonio has risen from 161,000 to 785,000 and the population of Bohar has increased from 202,000 to 987,000. In the wake of the instability of the Gulf of Mexico, the flow-dominated area of the Omoz Dam has seen a heavy rainfall over 100 years, such as the torrential rains of 1921 and 1972. Rainstorm area sometimes exceeds 31080 square kilometers. In 1973, the study found that flood calculation using several rainstorms covering the whole catchment area would cause the dam to overhang to varying degrees, causing the dam to withstand stress exceeding the allowable limit of the original design and reducing the safety factor so that the structure damage.
