The impact of anthropogenic channel alteration on the Retention of Particulate Organic Matter (POM) in the third-order river Ilm, Germany

Wagner, Falko

This paper describes new, easy to handle, liquid nitrogen sampler for the upper layer (80-160 mm) of water sediment and associated benthic organismus in streams and lakes up to 1.2 m depth. The 0.0531 m2 sediment sample keeps its natural composition and spatial structure. The 15 kg total weight of the two sampler components enables use by hand even in not easily accessible rural areas. A successful two year test period in several first and second order streams demonstrated the applicability of sampler for sediment textures from fine clay to cobbles and velocity up to 1 m s-1.
