Abstract

Almost in every rainy season the area around the River District Cupo Ngawi experienced flooding. This is caused by the inability of the capacity to accommodate Cupo River water discharge during the rainy season. Consecutive rain that often helps to improve the potential for river Cupo flooding. The concept of flood control embankment construction is planned along to left bank and right bank. Mean daily rain fall areas calculated by Polygon Thiessen, while rain fall design calculations using the Log Pearson III. To find out the current flood discharge calculated using the Rational Method and Method Nakayasu with 10years reapitly. Water surface profile analysis using software to divide into 8 stations, on relatively long embankment slope of 1 : 1.5. From the calculations, the total discharge 14.761 m3/sec, planned embankment with soilmaterials. The dimensions of embankment at the extreme poles is 1.0 m for the high embankment, and 5.0 m for the width of the embankment. After the seepage and stability control avalanches, the safety factor obtained 29.84 for normal conditions, and 25.51 for earth quake conditions.
