The Analysis of Hydro-Morphometric Characteristics of Qaladze Basin
Bakhtiar Osman Khzr
The research attempts to identify the fundamental standard characteristics of the Qaladze River Basin's water drainage network. One of the permanent rivers in Pishdar district's east, Sulaymaniyah Governorate's northeast, and Kurdistan Region's east. The most notable topographic elements that constituted the morphometric characteristics throughout the Pleistocene era were the most prominent geomorphological processes, most notably stream orders, the most extensive streams, drainage density, bifurcation ratio, texture ratio, and meandering coefficient. In the main Qaladze basin (6) stream orders, total number of streams is up to (358) tributaries, and their full-lengths are (235.56 km). The drainage density was attained (2 km/km2). In contrast, the numerical drainage density was obtained (3,03 streams/km2), the bifurcation ratio ranged between (2-7.22), the texture ratio was implemented (5.21 km), the meandering coefficient was struck (1.2), the extraction and flood coefficient was accomplished (8.2), and the runoff speed reached (3.9 m/s).

Nali Jawad Hamad
The study aims to evaluating the landform in the khalakan basin and its to preparing appropriate model for the capacity of the lands by using remote sensing (RS) technology and geographic information system (GIS) by depending on function of (Wighted-Overlay) which can be considered as one of the significant function of GIS. And in order to achieve the aim of the study, eight layers have been extracted for preparing appropriate ground model. according to the importance of each layer which is used to determine the ability and they are: (geological formations, slope, splash erosion, soil, plant cover (NDVI), elevation and lineaments, geomorphological unit) layers which can be considered as the result of Intrusive and extrusive processes. After the processes of Overlaying, the study successfully produced a general map for the appropriateness ground which categorized the area into three levels of appropriateness: the level of high appropriateness with area of(9.34Km), the level of mid appropriateness with area of (70.34Km) and the level with no appropriateness with area of (4.957Km.
