Abstract:
The study aims to detect natural factors and human influence in changing the map hydrological Map province of DhiQar, south of Iraq between latitudes (30.20 - 32.00) and attitudes (45.40 - 47.00) and find out their environmental consequences during the period (1990 - 2015) the study produce of maps of high hydrological accuracy based on remote sensing data of TV visuals using ArcGIS10.2 program one of the most GIS programs. Largest hydrological change is has been observed what happened in 2002, as it reduced the Hammar HorAoanh Gmokh marshes which dried up completely, including Hor Abu your button and Hor easier Gleuen Central and marshes after it was occupies large areas in 1990 and this is illustrated by the map hydrological for the year 1990 and 2002, then they returned these marshes occupies large areas after the recovery of the marshes, which occurred after the year 2003 operations and is continuing to the present time, which led to the emergence of some of the marshes in 2015 and of which Hor Justice low Alsalibat and Hor and some swamps in parts of the province and this is illustrated by the map Alheidroujeh for the year 2015 are installed in aboard the research, as well as that there was a change in the maps hydrological not only in the marshes, but in the number and lengths drainage conals characteristics morphometric for those hydrological units during the period (1990 - 2015) as there has been a change in the (length, width, area, the proportion of the cohesion of the ocean, elongation , rotation)The study also deals with the hydrochemical of rivers and marshes and drainage conals study area, as it was collected (42) samples from different locations than those Alhidologih units in February and July to explain discrepancies spatial and temporal in those characteristics that have signed the maps named maps hydrochemical. The was comparable standards international and global knowledge of their suitability for different uses.Follow this change in the map hydrological during the period (1990 - 2015) the occurrence raised environmental special study area during the year 2002, represented by the occurrence of a change in the climate characteristics of the province of DhiQar, as drought coefficient rose and shrinking vegetation and water cover space and the increase in the barren land area, as well as a clear shortage of Animal Resources and fisheries and change the numbers Mqarndta population in 1990 and 2015
