Abstract. Construction of warping dams destroys the consistency of annual maximum discharge series, which makes it difficult to calculate design floods, and even harder to calculate design floods in regions with no data. In this paper, an approach including consistency handling and regional formulae for statistical parameters was proposed to solve the problem encountered in calculation of design flood in no data regions influenced by warping dam projects. Analysis showed that the calculation results of such an approach are close to the actual situations and the approach has flexibility.
