Increased Asymmetry of Pit-Over-Peak Statistics with Landscape Smoothing
Shashank Kumar Anand, Amilcare Porporato
The local extremes (i.e., peaks and pits) of the landscape-elevation field play a critical role in energy, water, and nutrient distribution over the region, but the statistical dis…

Variational Analysis of Landscape Elevation and Drainage Networks
Milad Hooshyar, Shashank Kumar Anand, Amilcare Porporato
Landscapes evolve toward surfaces with complex networks of channels and ridges in response to climatic and tectonic forcing. Here we analyze variational principles giving rise to m…
