A double continuum hydrological model for glacier applications [PDF]

open access: yesThe Cryosphere, 2014
The flow of glaciers and ice streams is strongly influenced by the presence of water at the interface between ice and bed. In this paper, a hydrological model evaluating the subglacial water pressure is developed with the final aim of ...

Geomorphic Effects and Habitat Impacts of Large Wood at Restoration Sites in New England

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Large wood (used interchangeably with the term “instream wood”), which refers to trees, logs and other wood within a channel, is beneficial to river ecosystems and is being used more frequently as a component of river restoration projects. We identified metrics to evaluate the effectiveness of large wood to promote ecological and geomorphic ...

Modeling glacio-hydrological processes in the Himalayas: A review and future perspectives

open access: yesGeography and Sustainability
The Himalayas and their surrounding areas boast vast glaciers rivaling those in polar regions, supplying vital meltwater to the Indus, Ganges, and Brahmaputra rivers, supporting over a billion downstream inhabitants for drinking, power, and agriculture ...

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

Modelling glacier hydrology in West Greenland

open access: yesRapport Grønlands Geologiske Undersøgelse, 1981
There is great interest in the possibility of using runoff in West Greenland for the generation of hydroelectric power. However, there is still very little information about hydrological conditions in the country. For example, measurements of runoff and glacier mass balance were only started at a few sites in the late 1970s by the GTO and GGU ...

Assessing Spatial Riverbed Clogging and Its Dynamics at the Reach Scale: A Coupled Approach Combining Field Measurements and 1D Hydro‐Sedimentary Numerical Modeling

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Tropical climate and glacier hydrology: a case study in Bolivia

open access: yesJournal of Hydrology, 1995
Runoff from intertropical glaciers is highly variable, indicating that they are greatly affected by climatic changes peculiar to tropical climates. The 3 km2 basin presented in this case study lies in the Cordillera Real of Bolivia and is 77% covered by glacier ice, ranging in elevation from 6000 to 4830 m a.s.l.

RESPONSE OF CANADIAN ROCKIES GLACIER HYDROLOGY TO CHANGING CLIMATE [PDF]

open access: yes, 2020
This thesis investigates the impact of snow and glaciers in mountain hydrology under changing climate conditions and glacier configurations in the Canadian Rockies, where a warming climate and glacier retreat cause concern about changes in mountain ...

The consequences of elevated CO² and land use in alpine ecosystems [PDF]

open access: yes, 2014
The consequences of elevated CO2 and land use in alpine ecosystems This PhD thesis addresses two main aspects of Global Change and their impacts on alpine vegetation and eco-hydrology, (1) the steadily increasing concentration of CO2 in the atmosphere
