The US Gulf of Mexico coastal region has repeatedly been subjected to major flood events. Local geotechnical site characteristics and geomorphology can change due sediment transport processes during such However, field measurements extreme conditions are challenging. This paper discusses initial attempts at a combined geophysical investigation the uppermost layers riverbeds following severe flo...

Burrowing into riverbanks by animals transfers sediment directly river channels and has been hypothesised to accelerate bank erosion promote mass failure. A field monitoring study on two UK rivers invaded signal crayfish (Pacifastacus leniusculus) assessed the impact of burrowing processes. Erosion pins were installed in 17 across a gradient burrow densities monitored for 22 months. Bank retrea...

The problems regarding hunter-gatherer/early farmer interactions are quite an important topic in southeast European archaeology. According to the available data, two economic subsistence systems have coexisted for some 2000 years during 6th–4th millennia cal BC (Telegin 1985; Lillie et al., 2001). In areas, hunter-gatherer and early sites located just a few kilometers apart. Southern Buh River ...

Rapid water level decreases due to hydropeaking are known negatively affect riverine biota, mainly the stranding of organisms in river bank area that becomes regularly dewatered. Even though studies last decades have focused on salmonid fish, also cyprinids may be affected. However, limited knowledge is available this fish family. Therefore, we conducted mesocosm experiments under semi-natural ...

Abstract Wildlife abundance estimation is one of the key components in conservation biology. Bayesian frameworks are widely used to adjust potential biases derived by data collected field, as they can increase precision model parameter a consequence combination previous pieces knowledge (priors) combined with field produce an a-posteriori distribution. Capture-recapture most common techniques a...

Environmental rehabilitation of urban streams has been widely applied in Global North countries, at least since the 1970s, but it is a recent approach South countries. The objective this paper to evaluate whether experience carried out 2006 three stream sites third-largest Brazilian metropolis (c. 5.5 million inhabitants) was and continues be effective terms socio-environmental improvement afte...

Riverbanks undergo changes caused not only by river hydraulics, mainly sediment erosion and deposition processes, but also the possible landslides that eventually change channel bank profiles. Those failures are an important form of alluvial adjustments usually difficult to include during morphodynamic modeling. This paper proposes a novel approach combining 2D depth-averaged hydrodynamic, tran...

Introduction: Environmental compensation is a legal-administrative instrument used by agencies that supervise the environmental impact assessment (EIA) to offset irreversible impacts generated development projects. The usually framed in principle of ecological equivalence, which seeks equate losses due with net gain obtained compensatory actions. Methods: We analyzed records projects have merit...

Erosion at either dam or spillway foundations, destabilization in riverbanks, and damage the natural environment located downstream of dams spillways represent crucial elements to be taken into account risk assessment hydraulic structures. One main problems is related scouring that water flow may induce boundary spillways. This issue exacerbated case undersized stilling basins, i.e., when a sig...

Riverbanks are very dynamic habitats for riparian vegetation strongly influenced by fluvial and geomorphic processes. This habitat type was severely reduced in the past river straightening bank stabilisation. Restoration establishment of new floodplain streams promote this habitat, but a directed succession to later stages observed many times. Our study aimed analyse whether often streambank af...
