在三角形的暗影里是深达200米的白色漏斗形内心火山口。

Within the shadow of the ash cone lies a white, funnel-shaped inner crater that is 200 meters deep.

对库区纵、横向淤积形态，坝前区冲刷漏斗形态、尺寸及干、支流三角洲的关系进行了分析研究。

Finally, the longitudinal and transversal sedimentation patterns in reservoir, scoured funnel in front of the dam, and relation between main river and tributaries were also studied.

通过对宝石水库冲刷漏斗的试验分析认为，在边界条件限制下，冲刷漏斗将呈现二维结构，淤积三角洲基本向坝前平行推进。

According to the tests, the scour funnel would be two-dimensional feature under the specific condition. The deposit material transport to the dam synchronously.
