The Guadix Basin developed as an endorheic depression during the Upper Miocene–Upper Pleistocene. Its principal palaeogeographical characteristics are a large lake in the eastern sector, an axial fluvial system and two fluvial systems transverse to it in the western sector. The uplift of a central sector of the Betic Cordillera during the Upper Pleistocene affected the study area, causing north...

The widespread urbanization of the corridor of the Sarno River has drastically modified the environment of this fluvial system. The aerial recognitions show that “the river continuum” was replaced by a continuum of town centres developed along the course of the Sarno River and its tributaries often on both banks. The urban and industrial building areas appear as a continuum and the agricultural...

Gullies on Mars are km-scale landforms that resemble small fluvial features on Earth. Their discovery [1] challenged the paradigm that over the last ∼2 Ga, Mars has been a dry, frozen desert. The gullies are found commonly in the mid-latitudes, have a pole-facing preference [e.g., 2] and are found many kinds of steep slope (valley wall, dunes, etc.). We have chosen to concentrate on gullies fou...

A surface processes model incorporating large-scale fluvial processes, local hill-slope processes, and glacial erosion is used to investigate the effect of glaciation on the relief of a fast-growing, narrow orogen. The results of several simulations show that: glaciers concentrate erosion near peaks; fluvial erosion is reduced downstream of glaciers; glaciers with frozen bases can lead to an in...

Water-related disasters, such as fluvial floods and cyclonic storm surges, are a major concern in the world’s mega-delta regions. Furthermore, the simultaneous occurrence of extreme discharges from rivers and storm surges could exacerbate flood risk, compared to when they occur separately. Hence, it is of great importance to assess the compound risks of fluvial and coastal floods at a large sca...

[1] Mechanistic theories of fluvial erosion are essential for quantifying large-scale orogenic denudation. We examine the topographic implications of two leading classes of river erosion model, detachment-limited and transport-limited, in order to identify diagnostic and testable differences between them. Several formulations predict distinctly different longitudinal profile shapes, which are s...
