Historical temporal trends in groundwater levels from British Columbia, Canada [PDF]
A time trend study of groundwater monitoring well levels was conducted in British Columbia, Canada. Trend data was available for a total of 210 groundwater monitoring well stations throughout the province with end-of-month water levels over the period of

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring
ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

ABSTRACT Invasive species can fundamentally alter their introduced habitats by changing natural processes and harming native species crucial to functional ecosystems and human needs. Although the number of potential invasive species is large, the suitability of novel locations to support population establishment is limited by both physical and ...

The origin of fault scarps & fissures on moorland plateaux & in the vicinity of landslides, in the South Wales Coalfield, UK [PDF]
Fault scarps and fissures occur on moorland plateaux and in the vicinity of deep-seated landslides in the South Wales Coalfield, UK. These scarps may reach about 4 m in height and 3-4 km in length.

Identification, prediction and mitigation of sinkhole hazards in evaporite karst areas [PDF]
Sinkholes usually have a higher probability of occurrence and a greater genetic diversity in evaporite terrains than in carbonate karst areas. This is because evaporites have a higher solubility, and commonly a lower mechanical strength.

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

ABSTRACT Salmonid fishes typically express anadromy. During their juvenile riverine emigration, their downstream movements can be inhibited by hydropower schemes that entrain fish in their intakes. Here, the riverine migration success of smolts of brown trout Salmo trutta (“trout smolt”) and Atlantic salmon Salmo salar smolts (“salmon smolt”) was ...

Transfer function-noise modeling and spatial interpolation to evaluate the risk of extreme (shallow) water-table levels in the Brazilian Cerrados [PDF]
Water regimes in the Brazilian Cerrados are sensitive to climatological disturbances and human intervention. The risk that critical water-table levels are exceeded over long periods of time can be estimated by applying stochastic methods in modeling the ...

Using Trail Cameras to Monitor Culvert Connectivity in Wadeable Streams
ABSTRACT Anthropogenic barriers in aquatic habitats have led to fragmentation and decreased fish diversity worldwide. Road crossing barriers such as culverts are a significant source of fragmentation and can impede aquatic organism passage (AOP). Many large extent efforts to inventory road crossing barriers and prioritize restoration efforts do not ...
