An in-situ integrated sampler relies upon the natural sedimentation process to continuously collect suspended sediment from a flowing stream over extended time periods. An upstream facing funnel captures a portion of the flowing stream and directs it into a sedimentation chamber where the flow is slowed sufficiently to induce settling of sediment. A receptacle disposed within the chamber collects settled sediment and apertures in a base member allow excess water to escape from the chamber. A stake mounted in the stream bed can be employed to orient the sampler and position it at a desired depth. |
