This paper introduces a method for calculating the steady turning diameter of inland-water ships by using the nonlinear equations of steering motions.

Endogenous rivers often do not reach the sea but drain into inland basins, where the water evaporates or is lost in the ground.
内源河流通常不会流入大海，而是流入内陆盆地；在那里，水会蒸发或流失到地下。
