Topics in Cement and Concrete Research [PDF]

, 2006
In recent decades, the construction sector has faced many changes. One of these changes is the shift in the role of national government from one-sided practices in which the government was solely responsible for strategic and long-term spatial planning ...

Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

River Research and Applications, EarlyView.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

River Research and Applications, EarlyView.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Significant Human Modification of the Lower Arkansas River Sediment Budget

Geophysical Research Letters, 2022
Anthropogenic stressors on large rivers have significantly modified riverine sediment transport. However, the impacts of dredging and sand and gravel (S&G) mining are poorly monitored.

Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

River Research and Applications, EarlyView.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...

Early recolonization of a dredged lowland river by dragonflies (Insecta: Odonata)

Knowledge and Management of Aquatic Ecosystems, 2016
The influence of dredging on the dragonfly assemblages of the small regulated lowland River Krąpiel (north-western Poland) was analyzed a short time after the dredging. Dragonfly assemblages were destroyed, but they began to recover rapidly.

Novel Bio-Logging Tool for Studying Fine-Scale Behaviors of Marine Turtles in Response to Sound

, 2017
Increases in the spatial scale and intensity of activities that produce marine anthropogenic sound highlight the importance of understanding the impacts and effects of sound on threatened species such as marine turtles.

Can Environmental Markets Pay for More Sustainable Farm Dams? A Cost–Benefit Analysis

Sustainable Development, EarlyView.
ABSTRACT Farm dams are widespread artificial waterbodies that play a critical role in agricultural water security. Enhancing these systems through sustainable interventions such as fencing, hardened access points, and revegetation can improve water quality and deliver carbon and biodiversity co‐benefits.

Cannabis Agritourism and Local Pathways Toward Sustainable Development Goals in Northern California

Sustainable Development, EarlyView.
ABSTRACT Recent acceleration in global cannabis legalization offers a new context for examining the multiscale links between agritourism, sustainability, and international policy frameworks. In this study, Responsible Tourism is used to conceptualize cannabis agritourism in Northern California's Emerald Triangle as a strategy that may advance targets ...

Slip characteristics of planar and rough granite fractures under unloading normal force

Frontiers in Earth Science
Unloading processes are common in natural systems. Intense unloading activities can alter the frictional equilibrium of faults and induce their instabilities.
