Адаптация модели эрозии от стока талых вод, разработанной Государственным Гидрологическим Институтом, для проектирования противоэрозионных мер

Аннотация

Verification of Russian erosion models, using for evaluation of landless by melt water runoff, showed that the best results may be obtained by the equation of SHI, though it can't be used for soil protection projecting. We have improved this equation to exclude this defect. For this purpose the function of the slope length was given as an explicit one, the new slope gradient factor was included, the slope runoff was used instead of river's one, the soil erodibility was evaluated more accurately, the impact of slope gradient and granulometric composition of soil on the runoff coefficient was taken into account.
