Particle path characteristics at the large gravel-bed river Danube : results from a tracer study and numerical modelling
A tracer study performed on a 3 km long reach of the Danube River in Austria is presented. Forty artificial stones of 3 different sizes were produced and a coded radio acoustic transmitter was implanted. The positions of the stones were observed
monitored on a large gravel-bed river. The particle paths were found to be mostly bankline-parallel. A three-dimensional (3D) numerical model using a stochastic particle tracing approach was validated with the data, indicating that the observed positions
are well reproduced by the model. Single tracer stones were transported up to 1000 m during a single flood event. Size-selective behaviour could be shown and the incipient motion of the large 70 mm gravel was detected at lower discharges than predicted

Soils and geomorphology of the lower Little Cedar River valley, northeast Iowa
the Little Cedar River, soil development, sedimentological characteristics, and stone lines to distinguish alluvial units and landforms. Three Pleistocene surfaces were mapped in the valley, including two terraces and an erosion footslope. Holocene alluvial
The AA. investigated the alluvial stratigraphy, soils, and geomorphology along a section of the lower Little Cedar River to aid in understanding the processes forming this landform region. They used terrace- and floodplain surface height above

Calibration of the transport relations was based on bed load transport data collected over a wide range of flows on the Snake River and its 2 major tributaries within the study area in 2006 and 2007. Comparison of actual flows with unregulated flows
for the period since 1957 shows that operations of Jackson Lake Dam (JLD) have reduced annual peak flows and increased late summer flows. Painted tracer stones placed at 5 locations during the 2005 spring flood demonstrate that despite the reduction in flood
magnitudes, common floods are capable of mobilizing the bed material. Calculations suggest that the Snake River was not in equilibrium before construction of JLD, but was naturally in sediment deficit. This result highlights the value of transport data
