Morphotectonic is one of the new reconition methods of tectonic movements and earthquakes knowledge. Study and measurement of landscapes and forms which made by active tectonics are important objects in morphology science. Active tectonic movements have recorded in the morphology of rivers, drainages, alluvial fans and mountain fronts in a region. Research area is located between 55° 30' -57° 00' E and 32° 00' -33° 00' N in Central Iran structural zone. In this paper, we have studied geological map of Abdoughi and processed satellite images, digital elevation model (DEM), geomorphic and morphotectonic indices along the main faults. Also tectonic activities were measured in this area. The results of mountain- front sinuosity (Smf), ratio of valley-floor width to valley height (Vf) and ratio of valley width to valley height (V) indicate respectively: 1/15, 0/94 and 9/88 values. The displacement of the rivers, alluvial fans and triangular facets indicate tectonic activity during Quaternary along the faults. The morphotectonic evidences and seismicity data show which Abdoughi area is an active region.

 Today, the resiliency of the human centers, especially urban centers against the natural hazards such as earthquakes, is one of the main challenges in the targeted management of urban. One of the effective strategies in the control, containment and prevention of risks from earthquakes is zoning of urban areas in terms of vulnerability. In this regard, the purpose of this study was to determine the zoning and seismic active zones in the urban area of Urmia city. The seismic – tectonic situation and recorded seismic data  surveyed in the current study. findings showed that there were seismic active zones in the Uremia city area. The seismic effects and geo-tectonic results Verified, so the results marked that local geology condition would be effective in earth motion. This research investigated the local geology features especially fault, geo units and seismic data in zoning of seismic risk. Many methods are proposed by different researchers. In this study the SABTA (1987) method has been used for estimating seismic risk by using most important parameters such as seismic, fault and geology data. The obtained results showed that the P.G.A measure variation was from 0.035 to 0.33 which indicated the existence of seismic activity in the study area.

حذف شدیک جمله Identify water resources management and proper application of relevant officials and managers are the main concern. Groundwater as a most important natural resources of Iran needs to planning and management of all aspects. In this regard, a study done of the Shaharchay river basin in the west of the Urmia Lake and the northern structural, sedimentary zone of Sanandaj - Sirjan. The aim of the study is to identify areas where the water table is higher in groundwater. To achieve this, an interpolation of (IDW) water level underground of Shaharchay by using the data of piezometeric well, then matching results with the position of faults and available tectonic seismic data. fractures were checked and the role of basin natural characteristics such as slope, lithology, soil type, ages of Geological, precipitation and landuse on groundwater level fluctuations were checked as well. Investigations show 4 different patterns of movement of groundwater in the basin area. Except of fault, other criteria alone are not much of a water table. The results show that the the western part of the water table is located in a very low of ​​zoning , which has very high mountains with high slopes, high rainfall, no fracture Quaternary and pasture. Eastern part of the basin is located in the area of ​​medium and high underground water level only a part of the shores of Urmia Lake in this zoning has a very high water table. With very little gradient, local average precipitation, high permeability, active Quaternary faults, the garden and the city landuse. But the center of the basin zoning was very high with very low permeability, high slope, average precipitation and mixture of garden, forest and grassland usages. basin center located on high seismic intensity zone and density Quaternary faults. only because of the high level in the basin center of Silvaneh are active faults and a high intensity tectonic seismic.
 

Rivers are environmental forms that react strongly to changes in their bed, tectonic is the most important factor affecting morphology of the river, causing significant changes in river systems. In this study, using the digital elevation model (DEM), Geographic Information System (GIS) and Global mapper 13, we investigated the effect of tectonic activity on river systems in the eastern slopes of Mullah Daghi, southeast of Zanjan province, this The area is drained by Abhar river. Using the Digital Elevation Model (DEM) in the Arc Gis 10.2 software environment, required maps including geological maps, topography and…, Geological map of 1: 250,000 leaves of Zanjan was used to prepare the fault map. In order to achieve the research objectives, tectonic activity indicators including: are Mountain front sinuosity, basin shape, drainage density, longitudinal gradient of the river, River maze, basin asymmetry, hypersometric integral, the topographic symmetry of the basin and the width of the valley floor to the height. The combination of these indicators is achieved by the tectonic activity index (IAT). The results obtained through the Iat index indicate the activation of tectonic and neotectonic in the watershed of Ardejin and Abhar and the moderate activities in the basin of the zareh bash basin. The impacts of these activities on river systems that are different from the tectonic indexes in the studied basins, such as river meanders(main stream), coniferous formation (Ardejin watershed basin),  tilt watersheds  abhar and Ardejin and  the shape of the basins (Basin elongation zareh bash)
