| 1. | Alongshore bars are produced at the point of wave break .
沿滨砂洲是在波浪拍岸处形成的。 |
| 2. | Some of the bars and troughs are exposed by low tide .
一些砂洲和沟槽在低潮位时，露出于水面。 |
| 3. | The further growth of a bar is due to a lowering of sea level .
砂洲的进一步生长是由于海平面正在下降的结果。 |
| 4. | Tidal channels, deltas, and washover fans are characteristically associated with offshore bars .
潮汐水道、三角洲和冲刷扇典型地与滨外砂洲伴生在一起。 |
| 5. | The deepest relief along the bar is on the shoreward side where it is backed up by a lagoonal channel .

| 7. | The sand carried outside the bar is spread out over the slope by the expanding head of the rip current .
从砂洲外面搬出去的砂质物，在急流的汹涌水头作用下被展布于整个斜坡上。 |
| 8. | The growth of these bars is limited by the depth at which waves will plunge and prevent further sand encroachment .
这些砂洲的生长仅限于波浪能冲进的深度，并且阻挡了外边砂质物的进入。 |
| 9. | Such thickening is due to the relative noncompactibility of the sandstone of the bar as compared with the enclosing shale .
