Cs in flood - plain soils of the Techa river
The Techa river was contaminated in 1949-1956 from the nuclear enterprise "MAYAK". The investigations were carried out in flood plain of the Techa river in 1992-1999. In the upper and middle parts of the river the basic contaminator is I 3 7 Cs; downstream more active is 9 0 Sr. Density of contamination of soils with 9 0 Sr down the river changes from 600 to 200 kBq/m , and that with 1 3 7 Cs f...
متن کاملUrban Flood Analysis Model for Plain Tidal River Network Region
Considering characteristics of high river density, special underlying surface in plain river network region, and municipal drainage system function, river network drainage unit model is proposed, which is defined as a region surrounded by main river or embankment. Flood storage variety and control projects regulation of small rivers in each unit is simulated. With drainage catchment as an objec...
متن کاملHeavy Metals in the Flood Plain Deposits Along the Upper Clark Fork River
Concentrations of copper, arsenic and cadmium in sediments and soils deposited on the flood plain of the upper Clark Fork River drainage were determined to be one to two orders of magnitude greater than in soils from typical noncontaminated systems. Aerial deposition of metal particulates during the period of smelting activities (1884-1980) has contributed approximately 2% of the excess copper,...
متن کاملGIS Methodology for Characterizing Historical Conditions of the Willamette River Flood Plain, Oregon
Recent environmental developments have stimulated an interest in conservation and restoration of the historical Willamette River flood plain, both to protect against flooding and to provide wildlife habitat. In order to best utilize scarce resources, we characterized historical and modern river channel and flood-plain conditions to evaluate changes and help prioritize restoration sites. Using c...
متن کاملFlood Pulse Dynamics of an Unregulated River Floodplain in the Southeastern U.S. Coastal Plain
Annual flooding in low-gradient rivers is recognized as an important subsidy between the river and its broad adjoining floodplains. Unfortunately, relatively few lowgradient rivers are unregulated and retain their natural "flood pulse" behavior in most developed regions of the world. Furthermore, attempts to quantify flood inundation dynamics of any river floodplain are scarce. We used aerial p...
