Mapping specific landform entities in the past is mainly achieved by manually examining contour lines on topographic maps. Automated delimitation of specific landform from digital elevation data remains difficult in geomorphologic mapping. This paper presents a method to automatically identify five common surface features of karst landscapes: isolated karst hill or sinkhole, clustered karst hil...

In recent years, various process-based models for the evolution of regional landform systems have been developed (Coulthard, 2001). Quantitative models have considerable use in applied geomorphology, but also represent a good means we have for testing and developing theoretical models. Nevertheless, there remains a considerable gap between the detailed quantitative representation of individual ...

[1] Numerical landscape evolution models driven by uniform vertical uplift often develop a static drainage network and a precise balance between uplift and erosion. Small-scale physical models of uplifting drainage basins, however, continually reorganize by ridge migration and do not reach an ideal steady state. Here I show that the presence or absence of persistent drainage migration in a bedr...

The fluvial system is a major concern in modeling landform evolution in response to tectonic deformation. Three stream bed types (bedrock, coarse-bed alluvial, and fine-bed alluvial) differ in factors controlling their occurrence and evolution and in appropriate modeling approaches. Spatial and temporal transitions among bed types occur in response to changes in sediment characteristics and tec...

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 ...

The paper describes the development of a spatial modeling language and visualisation environment that simulates landscape processes. The virtual reality modeling language (VRML) is evaluated as a suitable technology for visualising landscape models. Examples for water runoff and landform evolution are given. D.
