Inception of Regular Valley Spacing in Fluvial Landscapes: A Linear Stability Analysis

Incipient valley formation in mountainous landscapes is often associated with their presence at a regular spacing under diverse hydroclimatic forcings. Here we provide a formal linear stability theory for a landscape evolution model (LEM) representing the ...

A new data set of granitic rock strength values from Yosemite Valley, California: applications to rock fall assessment

To explore connections between rock strength and rock falls, we undertook a comprehensive rock mechanics testing program for six granitic rock types in Yosemite Valley (California, USA) where rock falls are a common geomorphic and sometimes hazardous proce ...

From the clouds to the ground - Effects of flow-precipitation interactions on snow distribution in complex alpine terrain

Franziska Gerber

Knowledge about the spatial distribution of seasonal snow is essential e.g. to efficiently manage fresh water resources or for hydro-power companies. The large-scale gradient of snow accumulation over mountain ranges is mainly determined by lifting condens ...

Scaling of dissolved organic carbon removal in river networks

Tom Ian Battin, Enrico Bertuzzo

Streams and rivers play a major role in the global carbon cycle as they collect, transform and deliver terrestrial organic carbon to the ocean. The rate of dissolved organic carbon (DOC) removal depends on hydrological factors (primarily water depth and re ...

Morphological analysis of the upper reaches of the Kukuy Canyon derived from shallow bathymetry

Yosef Akhtman, Nicolas Le Dantec

We present preliminary results on the morphology of the upper reaches of the Kukuy Canyon and Selenga shelf in front of Proval Bay (Lake Baikal), derived from newly acquired, high-resolution bathymetry. Numerous and varied erosional and transport features ...

SEHR-ECHO v1.0: a Spatially Explicit Hydrologic Response model for ecohydrologic applications

Andrea Rinaldo, Enrico Bertuzzo, Bettina Schaefli, Ludovico Nicotina, Cédric Imfeld, Pierfrancesco Da Ronco

Abstract. This paper presents the Spatially Explicit Hydrologic Response (SEHR) model developed at the Laboratory of Ecohydrology of the Ecole Polytechnique Fédérale de Lausanne for the simulation of hydrological processes at the catchment scale. The key c ...

Street networks in relation to landforms: Implications for fast-growing cities

Nahid Mohajeri Pour Rayeni

In addition to socio-economic factors, major landforms may affect the city structure and urban form. Here we show that landforms have significant effects on the city shape and street patterns of the fast-growing Iranian cities of Dezful (a river) and Khorr ...

Geomorphic signatures on brutsaert base flow recession analysis

Andrea Rinaldo, Marc Parlange, Enrico Bertuzzo, Steven Vincent Weijs, Raphaël Mutzner, Serena Ceola, Ludovico Nicotina, Nevena Tomasic

This paper addresses the signatures of catchment geomorphology on base flow recession curves. Its relevance relates to the implied predictability of base flow features, which are central to catchment-scale transport processes and to ecohydrological functio ...

Geomorphic Signatures on Brutsaert Base Flow Recession Analysis: case study of 27 Swiss catchments

Andrea Rinaldo, Marc Parlange, Enrico Bertuzzo, Steven Vincent Weijs, Raphaël Mutzner, Serena Ceola, Ludovico Nicotina

Recession flow analysis are crucial in many areas of water resource management and useful to forecast base flow in gauged rivers. Moving from a classical recession curve analysis method, a large set of recession curves has been analyzed from Swiss streamfl ...

Observations, theory, and modeling of the differential accumulation of Antarctic megadunes

Michael Lehning

Antarctic megadunes are characterized by significant spatial differences in accumulation rate, with higher accumulation on the windward side and near-zero accumulation on the lee side. This leads to spatial differences in physical properties of snow and su ...
