本文以英国特伦特盆地古老的冲积沉积物为例，认为昆虫(主要是甲虫)的受涝遗迹可以用来探测全新世低坡度冲积景观中不同流量的发生和洪水-平原演变的变化模式。这种方法可能会提供宝贵的数据，因为沉积的细粒性质意味着缺乏其他类型的信息，如粗大的巨石护堤。三个高能和两个低能沉积物的鞘翅目组合对比表明，可以识别出一些明显的特征，并可以为区分这两种不同的沉积环境制定标准。这种方法是用从特伦特河谷下部斯帕尔福德草场的古河道填充物中发现的鞘翅目遗骸进行测试的。这一方法的应用有助于重建河流历史，这是了解谷底考古聚落模式分布的关键因素。
Using examples from dated alluvial deposits in the Trent basin, UK, this paper suggests that the waterlogged remains of insects, mainly beetles, can be used to detect the occurrence of varying discharge and changing patterns of flood-plain evolution in low gradient alluvial landscapes of Holocene age. This approach may provide invaluable data where the finer-grained nature of sedimentation means that other types of information such as coarse boulder berms are lacking. Comparison of Coleoptera assemblages from three high-energy and two lower-energy deposits indicates that a number of distinctive characteristics can be identified and criteria can be set for the distinction of these two contrasting depositional environments. This approach is tested using Coleoptera remains recovered from a palaeochannel fill at Spalford Meadows in the Lower Trent Valley. The application of this methodology could contribute to the reconstruction of river histories, a key factor in understanding the distribution of valley floor archaeological settlement patterns.
