بناء نماذج ديناميكية فيديوية (Multimedia) لتغير مسار نهر دجلة على امتداد مدينة تكريت

Abstract

The study used modern dynamic methods to represent the phenomenon of changing the course of the Tigris River for the period 1950-2022. One of the most prominent methods is the animated dynamic modeling or the so-called multimedia maps, and the 3D dynamic study was used.

    The study area is located in the central part of Iraq within the administrative boundaries of Salah al-Din Governorate, between latitudes (0′34⁰28-0′34⁰44) to the north, and longitudes (10′43⁰38-50′43⁰46) to the east. It is represented by the Tigris River along the city of Tikrit, which starts from the University of Tikrit in the north and the region of Al-Awja in the south. As for the east, it was defined by the area of Al-Alam, bypassing the city of Al-Alam, because the historical records indicate that the river has bypassed the city of Al-Alam, while it was defined from the west by the city of Tikrit all the way to the highway, relying on the contour lines of the city.

     The study concluded that the dynamic and mobile methods are the best in representing the ever-changing phenomena, especially rivers, as they reveal areas that change in the form of multiple media based on sound and moving images, which are the most effective in perception and reading. The study also revealed the availability of modern programs that address this problem, the most important of which is the geo da program in its modern version, as it is one of the best programs for dealing with distribution maps.
