Geomorphology of Lagrangian ridges [PDF]

arXiv, 2019
We prove an "h-principle without pre-conditions" for the elimination of tangencies of a Lagrangian submanifold with respect to a Lagrangian distribution. The main result states that such tangencies can always be completely removed at the cost of allowing the Lagrangian to develop certain non-smooth points, called Lagrangian ridges, modeled on the ...

A New Global Geomorphology? [PDF]

Geomorphology is entering a new era of discovery and scientific excitement centered on expanding scales of concern in both time and space. The catalysts for this development include technological advances in global remote sensing systems, mathematical ...

The influence of light attenuation on the biogeomorphology of a marine karst cave: a case study of Puerto Princesa Underground River, Palawan, the Philippines [PDF]

, 2014
Karst caves are unique biogeomorphological systems. Cave walls offer habitat for microorganisms which in-turn have a geomorphological role via their involvement in rock weathering, erosion and mineralisation.

The Geomorphology of Life

, 2021
<p>Since geologic time began, Earth’s surface has been evolving through natural processes (geologic and climate forcing). Now a new force of global change is altering Earth’s morphology in unprecedented ways: humanity.

Watersheds in disordered media [PDF]

arXiv, 2014
What is the best way to divide a rugged landscape? Since ancient times, watersheds separating adjacent water systems that flow, for example, toward different seas, have been used to delimit boundaries. Interestingly, serious and even tense border disputes between countries have relied on the subtle geometrical properties of these tortuous lines.

Transferring Google Earth observations to GIS-software : example from gully erosion study [PDF]

, 2013
High-resolution images available on Google Earth are increasingly being consulted in geographic studies. However, most studies limit themselves to visualizations or on-screen measurements.

Study Channel Changes and Bank Erosion in the Gamasiab River from 1958 to 2010 [PDF]

نشریه جغرافیا و برنامه‌ریزی, 2014
River channel change, such as bank erosion and accretion are natural processes in alluvial rivers. This paper aims to investigate migration and channel change plan form and effect on bank erosion and accretion done in Gamasiab River in Kermanshah ...

Gully cut- and- fill cycles as related to agromanagement : a historical curve number simulation in the Tigray Highlands [PDF]

, 2015
Gully cut-and-fill dynamics are often thought to be driven by climate and/or deforestation related to population pressure. However, in this case-study of nine representative catchments in the Northern Ethiopian Highlands, we find that neither climate ...
