Average Domain

Landscapes evolve towards surfaces with complex networks of channels and ridges in response to climatic and tectonic forcing. Here, we analyse variational principles giving rise to minimalist models of landscape evolution as a system of partial differential equations that capture the essential dynamics of sediment and water balances. Our results show that in the absence of diffusive soil transport the steady-state surface extremizes the average domain elevation. Depending on the exponent m of the specific drainage area in the erosion term, the critical surfaces are either minima (0 <  m  < 1) or maxima ( m  > 1), with m  = 1 corresponding to a saddle point. We establish a connection between landscape evolution models and optimal channel networks and elucidate the role of diffusion in the governing variational principles.

Folk Taxonomies

Bats are depicted in various types of media in Central and South America. The Moche of northern Peru portrayed bats in many figurative ceramic vessels in association with themes of sacrifice, elite status and agricultural fertility. Osseous remains of bats in Moche ceremonial and domestic contexts are rare yet their various representations in visual media highlight Moche fascination with their corporeal form, behaviour and symbolic meaning. By exploring bat imagery in Moche iconography, I argue that the bat formed an important part of Moche categorical schemes of the non-human world. The bat symbolized death and renewal not only for the human body but also for agriculture, society and the cosmos. I contrast folk taxonomies and symbolic classification to interpret the relational role of various species of chiropterans to argue that the nocturnal behaviour of the bat and its symbolic association with the moon and the darkness of the underworld was not a negative sphere to be feared or rejected. Instead, like the representative priestesses of the Late Moche period, bats formed part of a visual repertoire to depict the cycles of destruction and renewal that permitted the cosmological continuation of life within North Coast Moche society.

Stream Erosion

&lt;p&gt;The role of groundwater flow in determining overland flow, drainage density and landscape evolution has long been debated. Landscape models often only address groundwater as a simplified storage term and do not explicitly include lateral groundwater flow, although recently some model codes have started to include lateral flow. However, the role of groundwater flow on landscape evolution has not been explored systematically to my knowledge. Here I present a new numerical and analytical model that combines groundwater flow, saturation overland flow, hillslope diffusion and stream erosion. A number of model experiments were run with different values of transmissivity and groundwater recharge. The model results demonstrate that transmissivity, groundwater flow and the depth of the watertable strongly govern overland flow, the incision of stream channels and erosion rates. The results imply that the permeability and transmissivity of the subsurface are important parameters for explaining and modelling landscape evolution. &amp;#160;&lt;/p&gt;
