Bulanık-Malazgirt Basin (Muş) exists in the middle of this section and in the "Upper Murat-Van Section " of Eastern Anatolia Region. Bulanık-Malazgirt Basin (Muş) is included Euphrates River drainage basin hydrographically and it exists in downstream of Murat River at the top of this basin. Waters of the region are discharged to Euphrates River and from there to Persian Gulf by Murat River and its arms. Hydrographic properties of the basin were shaped by climate, geology and geomorphological factors of the field. The hydrographic properties of Bulanık-Malazgirt Basin (Muş) that exist in an important position in the Eastern Anatolia Region were'nt searced geographically. The purpose of this work in this framework, The hydrographic properties of Bulanık-Malazgirt Basin are to search geographically. In accordance with this purpose, Digital Elevation Model (DEM), digital topography maps, geological maps and numerical hydrographic data field of examination were analyzed with Geographical Information Systems (GIS). In addition to analyzes related to flow quantities and regimes of rivers were made with data of the flow monitoring stations of DSİ and analyzes of underground waters were made with Malazgirt, Bulanık and Patnos Plain Hydrological Survey Report (1978). At the end of work frequency of streaming web in Bulanık-Malazgirt Basin is not the same everywhere. The basin is fertile in terms of drainage types and climate conditions are decisive on the flow-regime conditions. Plains and basin floors are fertile in terms of groundwater.

The junction of several major structures and stratigraphic sequences is in the Konakpinar-Sarica area of central Turkey. Most of the area is underlain by Upper Jurassic to Cretaceous limestone and siltstone, early Tertiary sedimentary rock, and remnants of younger volcanic rocks and lacustrine deposits. The northeastern part of the area, however, is formed of serpentinite, of possible Cretaceous age, unconformably overlain by Upper Cretaceous conglomerate and silts tone that crop out extensively east of the area.. The regional structure changes direction in the area. Folds and faults change across a northerly striking hinge line from northeast trends on the west to northwest trends on the east. A north-trending regional fault zone is a little east of the hinge line. The northern part of this fault zone and yA northwest-striking fault, a possible thrust, east of it form the boundary between the two stratigraphic provinces. The area northeast of this boundary is cut by a series of vertical northwest-trending faults that are downdropped on the southwest. A large northeast-trending fault that is part of a broad fault zone that extends from the Mediterranean Sea north-* eastward to Divrigi is in the northwest corner of the area. Some thrust faults cut the Cretaceous rocks in the western part of the area; the Upper Jurassic limestone may be allochthonous. The only economic deposit known in the area is at the Otlukilise Iron Mine where iron is present in a sedimentary filling of sinkholes and as secondary replacement deposits in limestone at their borders. Minor deposits of chrome, copper, and coal also occur in the area.
