تغير الخصائص المورفومترية لمجرى نهر ديالى بين بعقوبة و المصب للمدة (1985-2016)‎

الملخص EN

This study dealt with morphometric aspect of the stream of Diyala River between Baqubah and Mouth of the River.

The area of study lies in an unstable pavement in the North-East of sedimentary.

The area includes a tectonic activity under the surface which works to make continuous slope.

The geology of the area is formed of modern river residuals of the fourth age going back to the age of playostosen and Holocene.

It is obvious that the area is flat and the slope of surface is from North- East till South-West.

The climate of area is continental climate which is within a regional dry climate having the aspect of high temperature degrees and less fall of rain with oscillation in it elements totally.

During the study it appears that the area contains different natural plants growing on the banks of the river and in the middle of the stream.

The soil appeared to be transported soil by the Diyala River and hugest part of it is mud of two types; soil of banks of river and soil of flood residuals.

The study included (21 stations) distributed within the area of study and showed differences in amount of river curving and differences on the length of the wave of the curves and differences in the average of river width and changes of banks and curves of Diyala river within the area of study.

The results showed visual satellite comparison of the stream of Diyala River in area of study for the years (1985-2000-2016) changing happened and for this purpose the study included morphometric analysis.

It appeared by morphometric measurements of visual satellite of the three periods increase and decrease of river length for the same three periods.
