enzymes are so crucial in the mineralization process of organic material. information of the soil enzymes activity is used in determining of the soil microbial properties and they are also important in soil health and quality. topographic attributes, soil properties and soil enzymes are associated together. hence, it is essential to know how these parameters affect on the soil enzymes activity....
gully erosion is one of the most severe types of water erosion that inclusive and global model to represent its development under different environmental circumstances is difficult. moreover, having knowledge about history behaviors of a gully and its advancement requires direct annual monitoring that is not possible in iran conditions because of cost and time. gis and remote sensing with provi...
Many geomorphic phenomena such as bank failures, landslide dams, riffle-pool sequences and knickpoints can be modelled spatial point processes. However, the locations of these are constrained to lie on or alongside rivers, their analysis must account for geometry topology river networks. Here, we introduce a new numeric class in TopoToolbox called Point Pattern Stream networks (PPS), which supp...
despite of suitable geological and climatic conditions for forming and evolution of alluvial fans and importance of this landform as soil and water resources in arid regions, there are limited studies about this landform in iran. in the present study, evolution and pedogenic development of geomorphic surfaces of an alluvial fan in eastern isfahan were studied by using remote sensing, field and ...

Visualizing large data by the SOM and GTM methods – what are we obtaining? Anna Bartkowiak University of Wrocław, Institute of Computer Science, Przesmyckiego 20, Wrocław 51–151, PL Abstract We consider the visualization of multivariate data yielded by the SOM and the GTM methods. Special emphasis is put on the position of outliers and extreme points. When evaluating four data sets, it is found...
Development and interpretation of morphometric maps are important tools in studies related to neotectonics and geomorphology; Geographic Information Systems (GIS) allows speed and precision to this process, but applied methodology will vary according to available tools and degree of knowledge of each researcher about involved software. A methodology to integrate GIS and statistics in morphometr...
