Cartographic generalization and its reflections on the morphometric characteristics of the upper Daquq-Jai basin

Abstract

The study area is located in the upper parts of the Daquq Gay Basin in Kirkuk Governorate, between latitudes 35, 7, 9 - 35, 42, 43 north and longitudes 44, 50, 24 - 45, 25, 47 east. The research topic aims to know the most important The morphometric characteristics of the basin by applying the rules of cartographic generalization and their effect on the variables of the morphometric values. This is done through the analysis processes followed based on digital elevation models and the geographic information systems program Arcgis. The research problem is summed up in arriving at the most important variables for the morphometric characteristics of the basin and the extent of the influence of the scale change according to the rules of generalization with different scales. On the morphometric analysis values, scales of 1:90,000, 1:170,000, and 1:400,000 were used. The analysis of the study revealed that the basin falls within the ninth rank, that the lengths of the waterways of the basin are different, and that the bifurcation ratios of the basin are different according to the different scales. The morphometric variables were revealed in terms of the results we reached, and it must be There is a detailed study related to the research area
