Investigation of quaternary deposits from the view point of direct evaporation from groundwater reservoir
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 6
Abstract
The main objective of this research is calculation of evaporate rate and it's zonation in Quaternary deposits of Segzi plain. After preparation of basic maps, the location of wells and their water-table statistic in the region were determined. By calculating D10 and by entering the data in GIS software and their interpolation, isocapillary map is prepared and is subtract from water-table surface isodepth map. Other hand, with separation of photometric units on the band compound 7-4-1 and using collected samples texture, soil texture map and subsequently soil porosity map were drown. Then using existence maps in affected evaporate areas through capillary rise, with multiple areas in the water high obtained from abstraction of capillary rise and groundwater depth in each month, the monthly vaporizable water volume per year was calculated. The result have shown that evaporation in the region is highly related to the depth of water- table and the rate of capillary rise.
