A conceptual model of the hydrological influence of fissures on landslide activity [PDF]

Hydrology and Earth System Sciences, 2012
Hydrological processes control the behaviour of many unstable slopes, and their importance for landslide activity is generally accepted. The presence of fissures influences the storage capacity of a soil and affects the infiltration processes of rainfall.

Patterns in fish assemblages in the Loire floodplain: the role of hydrological connectivity and implications for conservation [PDF]

, 2007
Hydrological connectivity is known to determine biodiversity patterns across large river floodplains, but it is often greatly altered by human activities.

Review of mechanism and quantifying methods of river system connectivity

Shui kexue jinzhan, 2017
"Connectivity" in a river ecosystem originated from landscape ecology, which plays a significant role in hydrological cycle, wildlife migration, and environment improvement.

Connecting fluvial levee deposition to flood-basin hydrology

Journal of Geophysical Research: Earth Surface, 2019
Abstract Levees are commonly found along every kind of river system, yet there are no widely accepted models for where along the channel they form and what controls their shape. In this study, we investigated whether levee growth is driven by sediment transfer from the channel adjacent to the levee or by inundation dynamics in the ...

Low flow controls on benthic and hyporheic macroinvertebrate assemblages during supra-seasonal drought [PDF]

, 2009
Despite the widely accepted importance of the hyporheic zone as a habitat for stream macroinvertebrates during floods, few data exist regarding community composition and distribution during periods of low flow or drought in perennial streamsi ...

Correlates of zooplankton beta diversity in tropical lake systems. [PDF]

PLoS ONE, 2014
The changes in species composition between habitat patches (beta diversity) are likely related to a number of factors, including environmental heterogeneity, connectivity, disturbance and productivity. Here, we used data from aquatic environments in five

Assessment and Optimization of Hydrological Connectivity for Effective Management of Water Resources in the Samian Watershed [PDF]

برنامه ریزی فضایی
Water scarcity has become a critical issue in some regions. Accordingly, increasing attention has been given to the structural and functional connectivity of river networks as the primary source of surface water supply, while this can be a potential ...

Evaluation of river connectivity using a composite index method and its impact on nutrients dynamics in large rivers

Ecological Indicators, 2023
The connectivity of large rivers is impaired by human activities, which could cause severe consequences to hydrodynamics, water quality. To clarify the changes in hydrological connectivity of large rivers and their effects on nutrients, a composite index

Development and testing of a risk indexing framework to determine field-scale critical source areas of faecal bacteria on grassland. [PDF]

, 2009
This paper draws on lessons from a UK case study in the management of diffuse microbial pollution from grassland farm systems in the Taw catchment, south west England. We report on the development and preliminary testing of a field-scale faecal indicator

Identifying freshwater wetland suitable habitat through a hydrological-biological connectivity framework: A case study of Naoli River wetlands, China

Ecological Indicators
Changes in hydrological connectivity not only interfere with the material transfer and energy flow processes within wetland ecosystems or between wetland ecosystems and other ecosystems but also pose potential risks to the ecosystem service functions of ...
