终止于Chryse Planitia的大型火星外流通道是洪水事件的残留物，涉及数百万立方公里的地下水的局部排放，超过了区域地壳中的储存量。我们使用一个动态地下水模型来证明，积雪或冰川的Tharsis上升，形成在高湿度期间，当冰是稳定的在低纬度地区，可能提供了一个有效的补给源和水头的circum-Chryse流出通道。在Tharsis补给模型中，水通过流出通道排出的速度比类似的南极补给模型快几倍。
The large martian outflow channels terminating in Chryse Planitia are remnants of flooding events involving the localized discharge of millions of cubic kilometers of subsurface water, more than can be regionally stored in the crust. We use a dynamic groundwater model to demonstrate that snowpack or glaciers on the Tharsis rise, formed during periods of high obliquity when ice was stable at low latitudes, may have provided an efficient source of recharge and hydraulic head for the circum‐Chryse outflow channels. Water is discharged through the outflow channels several times faster in Tharsis recharge models than in comparable South Pole recharge models.
