Fluvial landscapes of the Harappan civilization.
The collapse of the Bronze Age Harappan, one of the earliest urban civilizations, remains an enigma. Urbanism flourished in the western region of the Indo-Gangetic Plain for approximately 600 y, but since approximately 3,900 y ago, the total settled area and settlement sizes declined, many sites were abandoned, and a significant shift in site numbers and density towards the east is recorded. We...
متن کاملMetapopulation Persistence in Random Fragmented Landscapes
Habitat destruction and land use change are making the world in which natural populations live increasingly fragmented, often leading to local extinctions. Although local populations might undergo extinction, a metapopulation may still be viable as long as patches of suitable habitat are connected by dispersal, so that empty patches can be recolonized. Thus far, metapopulations models have eith...
متن کاملAssessing the relative efficiency of fluvial and glacial erosion through simulation of fluvial landscapes
The relative rates of erosion by rivers and glaciers, and the topographic effects of these two different styles of erosion, remain outstanding problems in geomorphology. We use a quantitative description of local fluvial landscapes to estimate how glaciated landscapes might look now had glaciers not developed. This indicates the landscape modification attributable to glacial erosion. We present...
متن کاملEvolving Landscapes for Population Games
We consider population games where the possible actions of each player are labeled by a real number that ranges over a finite interval. The adjustment dynamics of such games can be visualized as motion over a “landscape” the surface defined by a payoff or fitness function. A leading example is gradient dynamics, in which the speed with which a player changes action is proportional to the gradie...
متن کاملNew Mesoscale Fluvial Landscapes – Seismic Geomorphology and Exploration
Megafans (100-600 km radius) are very large alluvial fans that cover significant areas on most continents, the surprising finding of recent global surveys. The number of such fans and patterns of sedimentation on them provides new mesoscale architectures that can now be applied on continental fluvial depositional systems, and therefore on . Megafan-scale reconstructions underground as yet have ...
