Mathematical models of geomorphic processes can have value as both predictive tools and precise conceptual frameworks. Well-posed mechanistic models have great conceptual value because they link geomorphic processes to universal scientific principles, such as conservation of energy, momentum, and mass. Models without this linkage (e.g., models based exclusively on cellular rules or empirical co...

Two of the geomorphic Laws of Drainage Net Composition are discussed and it is shown that they are essentially abstract mathematical relationships that hold for any bifurcating system. Some of the geomorphic factors that determine the value of the characteristic coefficients that are obtained by application of the Laws to single nets are also discussed.

geomorphic indexes are useful tools in identification of evaluation in trace of tectonic activity (relatively rapid or even slow). since the drainage network morphology and behavior changes resulting from tectonic activity are very sensitive it seems to be evidence such as crossing the fault line and changes river bed affected by the neotectonic activities in basin. thus, for understanding and ...

“Urbanization” encompasses a diverse array of watershed alterations that influence the physical, chemical, and biological characteristics of streams. In this chapter, we summarize lessons learned from the last half century of research on urban streams and provide a critique of various mitigation strategies, including recent approaches that explicitly address geomorphic processes. We focus first...

High-resolution topographic data expand the potential of quantitative analysis of the earth surface, improving the interpretation of geomorphic processes. In particular, the morphologies of the channel beds of mountain streams, which are characterised by strong spatial variability, can be analysed much more effectively with this type of data. In this study, we analysed the aerial LiDAR topograp...

This study examines the role of surface geomorphic features in tree establishment at the alpine treeline in Glacier National Park, Montana, through the presentation of a multiscale, conceptual model of biogeomorphic relationships at alpine treeline. Empirical observations gathered through a multiscale field methodology over three summers serve as a base for the model. The model highlights the i...

Morphotectonic investigations were carried out by the use of morphometric indices which serve as a tool of identification in regions with active tectonic warp. Landforms in active deformation area are produced from relations of tectonic and surficial processes. One of the most significant landforms underground is rivers that are extremely responsive to tectonic movements mainly uplift and tilti...

Most geomorphic transport laws proposed to date are local in character, i.e., they express the sediment flux at a point as a function of the elevation gradient or curvature or other geomorphic quantities at that point only. We argue that non-local constitutive laws, in which the flux at a point depends on the conditions in some larger neighborhood around this point in space and/or time, present...
