O článku:
The technique of photogrammetry permits the study of contemporary river channel changes if the river is large enough and characterized by active evolution of geomorphic pattern. Results presented in the study confirm the dynamic and continual change of the Sacramento River channel and floodplain. The results also showed the channel narrowing along the active channel and straightening of the channel. This specific evolution of the river channel may be generally attributed to local geological conditions, discharge, the occurrence of floods, sediment transport, resistance to erosion and type, presence and density of vegetation. All these causes, except geological conditions, can be influenced by human activities. Analysis of the data set, enhanced by a wide range of field measurements and observations, have demonstrated a successive diminishing of the active floodplain and also higher occurrence of the river cutoff lakes.
