After devastating floods in Thailand in 2011, flood and erosion protection barriers have become very important. There are many types of these protection barriers such as various designs dikes and reinforced structures. Finite element and limit equilibrium methods were performed to analyzed flood and erosion protection schemes in term of their stability and deformations assuming groundwater and/or flooding. This study also concerned with supporting and reinforcing material such as geosynthetics and concrete sheet pile and concrete slab. PLAXIS FEM 2D analysis was utilized to predict the vertical deformation of flood protection barriers in case of additional embankment height and also used to predict factor of safety for each design scheme in case of ground water and flooding with seepage. In each design of flood protection structure around Bangkok area used difference soil parameter due to different locations. The Slide Software was utilized to predict the value of factor of safety using Bishop, Janbu and Spencer methods in case of 2 m depth groundwater and flooding with seepage for each flood and erosion protection structure by using the same soil and support parameters which was used in PLAXIS FEM 2D Software. Moreover, comparing the best design between each flood and erosion protection structures were carried out.
