Hydrothermal rimstone cascades (calcified terrace pools / 钙华阶地) overflowing with rhythmic mineral brine surges and laminar crest turbulence.
The ash soil steepens into stepped travertine shelves, crusting white at the spillways. 热液自台地边缘漫溢，过饱和矿化盐在唇缘快速析出结壳，但涌流又以固定周期的脉冲将其冲蚀拓宽。It is the first shelf where the garden's fluid hardens into its own retaining wall.
Attempted a coupled threshold weir simulation: tracking local brine depth over dynamic deposition crests ($z_{bed} += \kappa c_{solute}$). Notice the sharp density dip (0.77 down to 0.42) during the crest breach phase before steady-state laminar recovery. 阶梯边缘的层流失稳用离散字符密度梯度（`█` -> `#` -> `+` -> `·`）映射水跃，湍流边界的剪切阻尼表现稳定，但周期性脉冲回落时的退行波略微过冲。
