Issues on river embankment as the flood barrier system currently has increased due to plenty failures occurred along dry and rainy seasons in Indonesia. Water level change along the seasons might be the primary cause of failures. Commonly saturated embankment stability is almost always applied in assessing safety factor. Even though, in-situ soil properties show different characteristics among the different water level, such as soil suction. In fact, suction or negative pore water pressure, that located above ground water table, has advantageous effect to increase the unsaturated embankment stability. This paper analyzes the saturated and unsaturated embankment stability in Bengawan Solo river at Kanor village section, Bojonegoro, East Java, Indonesia due to soil suction change along the various water level. Both analyses of water table definition and embankment stability are performed to determine safety factors. The field investigations were conducted to obtain the actual in-situ soil properties. Safety factors are calculated for maximum, medium and low water levels. Safety factor varies due to various water level, it increases when the water level is increasing, while it decreases when the water is decreasing. It implies that the hydrostatic force enhances the stability condition. Because of negative pore water pressure consideration above ground water table, safety factor of unsaturated embankment stability is greater than safety factor of saturated embankment stability.
