TY - JOUR ID - 1076416 AU - Šulc Michalková, Monika PY - 2009 TI - Diachronic analysis of floodplain lakes of the Sacramento River JF - Geografický časopis VL - 61 IS - 4 SP - 257-268 EP - 257-268 SN - 00167193 KW - lateral erosion KW - floodplain lake KW - human influence KW - Sacramento River N2 - This study is based on temporal (diachronic) analysis of floodplain lakes using aerial photographs (1942, 1962, 1985 and 1999). The synchronic analysis researches into the internal linkages of a system at a given point in time. A diachronic analysis regards the phenomenon in terms of developments through time. We analysed the planimetric changes in order to highlight the spatial structures and their stability over time. Aerial photography is used for diverse diachronic analyses of channel change on the Sacramento River, California. Georeferenced and rectified aerial photos and maps are most desirable for use in the analysis of meander migration and floodplain lakes. All data were integrated into a GIS database (ArcGIS 9.3). Three main types of floodplain lakes were observed according to their spatial geometry, plug length and connection to the main channel: the oxbow lakes, the straight backwaters and the straight secondary channels.
