The soil and water conservation hold the key position in agricultural position and watershed development. The expenditure incurred in construction is of high magnitude and hence structure need to last for longer duration in the field. The study was undertaken to study and compare the existing design procedures used in Department of Agriculture and reported in literature for various temporary and permanent soil and water conservation structures and to estimate the expected life of different soil and water conservation structures based on hydrological approach. It was revealed that the design return period considered in the design procedures adopted by Department of Agriculture are very less and hence the expected life of structure is less. This means that there is risk of failure of these structures due to unexpected high flows. The design return period for temporary, semi-permanent and permanent structures should be worked out by assigning certain risks of failure.
