| Abstract: | AIM: To clarify the mode and features of dispersal movement of Oncomelania snails in the static and running water and to explore new approaches of controlling snail dispersal. METHOD: The study was performed by using the methods and theories on hydraulics, silt motion mechanics and snail biology. RESULTS: The threshold value of the relationship between the snail movement in the running water and the water current velocity was obtained for the first time. Meanwhile, five parameters that indicate the movement characteristics of the snails in the water body including the snail sedimentation rate in static water (range: 0.94- 17.1 cm/s), the snail sedimentation rate in running water (range: 8.6- 43.7 cm/s),and the current velocity for starting movement of snails (range: 30- 40 cm/s) were obtained and seven relevant mathematical formulas were deduced. CONCLUSION: The features of the movement of snails in the water body were provided. |
