In this study using the Idrisi software system, a methodology for jointly analyzing and interpreting multi-spectral images and DEMs for extracting structural-geology features is given. In analyzing and interpreting multi-spectral images for geological features, certain criteria are employed to acquire information about the geological structures of the land, such as topographic, geomorphologic, ...

The effect of artificial island on the geomorphologic processes in coastal area under coupled hydrodynamics, wave, and sediment transport system is a complicated multi-scale problem. Studying these dynamic will suggest how ecological restoration should be conducted. In this study, unified, unstructured, gridded model topographic evolution were adopted. Based field observations water depth, velo...

The most crucial but difficult task in the analysis of the risk due to landslide hazard is the estimation of the conditional probability of the occurrence of future landslides in a study area within a specific time period given the presence of spatial and geomorphologic features. This contribution explores a modeling procedure for estimating that conditional probability. The procedure proposed ...

Although many different erosion processes affect the coastal area of South Iran, wind caused erosion, considered a restrictive factor in human activities, makes one of the more common landscapes of the coastal strip. Therefore the recognition of wind caused erosion and its result is inevitable to conduct an effective coastal management. This study discusses the littoral geomorphologic shape of ...

the geomorphology is an important branch of natural geography that its goal is promotion of human life, ultimately. the geomorphic processes have considerable impact on human life, and opposing, human activities and behaviors have its impacts on the geomorphologic units and geomorphologic processes, enhancing the above argument. the gilan county, at its geographic position; embraced by two stru...

[1] The Transantarctic Mountains (TAM) define the western flank of the West Antarctic rift system. Cape Surprise, near the Shackleton Glacier in the central TAM, is the only location along the range’s >3500 km length where upper Paleozoic Beacon Supergroup strata are down-faulted to near sea level. Previous studies have inferred a range front master normal fault accommodates extension and rock ...

1. This review focuses on the connectivity between river and groundwater ecosystems, viewing them as linked components of a hydrological continuum. Ecological processes that maintain the integrity of both systems and those that are mediated by their ecotones are evaluated. 2. The hyporheic zone, as the connecting ecotone, shows diverse gradients. Thus it can be characterized by hydrological, ch...

the volume and surface area of the coast is a function of basin water levels. recognizing the factors of coastal geomorphologic changes could have a pivotal role in planning and managing the coast. effective factors in the formation and evolution of geomorphologic factors such as geological, tectonic, paleoclimatic, paleoclimatic and sea level changes have been considered in this study and the ...
