The Atlantic coast of NW Spain, where shingle beaches appear today, has suffered an important mobilization of dunes from a sea level about −120 m (bpsl), 20 ky ago. This aeolization caused the collapse of coastal/fluvial ecosystems (as forests) until the Late Holocene.

Analysis of Barchan morphology in the west of Loot desert using morphometric features [PDF]
In this article, we analyzed the morphology of barchans (crescentic sand dunes) using morphometric features of seven components of this landform in the west of the Loot desert near Pashoeyeh village. The components were height, width, length of the right

Morphological classification stability of Zab river channel on Rosgen method [PDF]
Introduction Rivers are one of the best geomorphic landscapes in which the connection between the system of forces and the forms of unevenness can be clearly understood (Chorley et al., 2000: 163).

This paper uses a numerical landscape evolution model to reconstruct the topographic history of Madagascar since the Late Cretaceous. The model is optimised by balancing the volumes of onshore erosion and offshore sedimentation; the former is predicted with erosion laws and based on uplift history inferred from elevated planation surfaces.

Assessing the Impact of Chemical Algae Management Strategies on Anurans and Aquatic Communities
Abstract Pond management with chemical and biological agents that reduce overgrowth of algae is an important means of maintaining water quality in residential ponds, yet the effects on nontarget species are not fully understood. We assessed the impact of Aquashade (a common nontoxic pond dye) and copper sulfate (a toxic algaecide) on American toad ...

Geomorphology and geomorphological landscapes of Fuentes Carrionas [PDF]
A 1:12,000 geomorphological map of Fuentes Carrionas (Northern Spain) is presented. Geomorphological landscapes maps are also shown to support map interpretation and show the area's geomorphological diversity. The maps were developed using the IGUL (Institut de Géographie, Université de Lausanne) geomorphological mapping legend.

Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

Rock slope failure preparation paced by total crack boundary length
Gravitational mass wasting prediction requires understanding of the factors controlling failure. Prior to slope failure, cracks in the weakened rock are thought to grow and coalesce, eventually forming a continuous failure plane.

Reconstruction of the collapse of the 'Azure Window' natural arch via photogrammetry [PDF]
The Azure Window was a natural arch situated in the west coast of Gozo (Maltese Archipelago) that collapsed in March 2017. We employ a Diver Propulsion Vehicle-mounted camera system to capture data for the 3D-modelling of this collapsed arch via photogrammetry. We demonstrate use of this method to document complex underwater geomorphology spread across
