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 کاملModeling environmental factors on vegetation destruction in protected areas
Over the past two decades, degradation damage has increased in natural ecosystems. This research focuses solely on the degradation of soil and vegetation cover in Sorkheh Eshpar National Park. For this purpose, some physical properties of the soil (specific gravity and true porosity, moisture content, a percentage of pebbles, acidity and conductivity and soil texture) were measured. Also, the d...
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...
