introduction one of the factors affecting in the control of environmental hazards, is the stability of the structure landforms. human activities especially in the case transportation, and also the need to expand it in different areas, can significantly affect on the region geomorphologic structures and causing high damages on life and financial. as a result, human activity can operate as a fact...

There are some Geomorphologic evidences of climate changes as alternate dry and wet climate in central parts of Iran. Maharloo Lake is a location that has protected the mentioned evidences as surfaces of detrital and evaporating sediments. The Lake drains an area of 4266 km2 and its present- day climate is dry so that evaporation is more than precipitation. Its climatic and lithological conditi...

Terrestrial laser scanning is of increasing importance for surveying and hazard assessments. Digital terrain models are generated using the resultant data to analyze surface processes. In order to determine the terrain surface as precisely as possible, it is often necessary to filter out points that do not represent the terrain surface. Examples are vegetation, vehicles, and animals. Filtering ...

Background and purpose: Finding a suitable location for the solid wastes is necessary for urban development projects. The Gonad city with a population of 131 108 people will produce 120 tons of garbage per day. This amount of wastes is buried in two temporary sites (adjacent of the river) and a permanent. Wastes leachate infiltration into the ground water river cause pollution and other environ...

in response to the demand for soil spatial information, the acquisition of digital auxiliary data and their matching with field soil observations is on the increase. with the harmonization of these data sets, through computer based methods, the so-called digital soil maps are increasingly being found to be as reliable as the traditional soil mapping practices, and with no prohibitive costs. the...

We examine portage sites in the U.S. South, Mid-Atlantic, and Midwest, including those on the fall line, a geomorphologic feature in the southeastern U.S. marking the final rapids on rivers before the ocean. Historically, waterborne transport of goods required portage around the falls at these points, while some falls provided water power during early industrialization. These factors attracted ...

Javoří hory Mountains is a part of Intra Sudetic Basin that belongs to the Permian-Carboniferous section of the Bohemian Massif, whose geological evolution was strongly influenced by volcanic activity. In the Pleistocene epoch cryogenic processes modeled the mountains significantly (frost cliffs, gelifluction streams), which resulted, in connection to the slope orientations, in substantial moun...

study area is located in west of iran with relatively rough topography. lithologic units in the region belong from jurassic and cretaccous till recent era. the study area of the alvand mountain region is related to the tectonic zone of the sanandaj-sirjan region and the area dominant neo-tectonic regime appears to be compressional-extensional type. one of the identification tools to find out th...
