Hazards due to large wood accumulations: Local scour and backwater rise

E3S Web of Conferences, 2018
Large wood (LW) in rivers increases the flow variability and provides habitats for various species. During flood events, transported logs can accumulate at river infrastructures and increase the flood hazard.

Simultaneous Effect of Collar and Roughness on Reducing and Controlling the Local Scour around Bridge Abutment

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Investigation of local scour around hydraulic structures particularly bridges is of crucial importance in river engineering. Bridge destruction mostly occurs as a result of scour phenomenon around piers and abutments, not because of structural weaknesses.

The importance of biodiversity components differs among wood‐based material Nature's contributions to people (NCP) in a tropical montane ecosystem

Oikos, EarlyView.
Biodiversity can influence forest productivity, but this does not necessarily translate into higher provision of wood‐based Nature's contributions to people (NCP), as only a subset of the wood produced is used for each NCP. Biodiversity–NCP relationships therefore require further assessment.

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

Investigating the effect of curved shape of bridge abutment provided with collar on local scour, experimentally and numerically

Ain Shams Engineering Journal, 2015
Scour around bridge supports such as abutments can result in structural collapse and loss of life and property, so there is a need to control and minimize the local scour depth.

Assessment of Local Scour at Bridges Abutment

Research Journal of Applied Sciences, Engineering and Technology, 2014
الأضرار الاجتماعية والاقتصادية هي أهم أضرار تعطل الجسر. ترتبط مشاكل استقرار هذه الهياكل ضد الفشل وعمق الدعامات ارتباطًا مباشرًا بكمية التنظيف المعدلة. كان الاقتصاد والموثوقية والاستقرار هي الاهتمامات الرئيسية بشأن تعزيز تصميم جسور الدعامة لمنع أو تقليل نظافة الركائز.

Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

People and Nature, EarlyView.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

The Effect of Geotextile Layer in Decreasing Local Scour of Cylindrical Bridge Pier

علوم آب و خاک, 2017
Flood currents are considered threatening factors by creating local scour along bridge piers. One method for decreasing local scour is to strengthen the bed against imposed tensions.
