Velocity Analysis of a Flow Passing over a Vegetated Slope [PDF]
, 2014 A sheet flow or overland flow is simulated by the theory of laminar flow passing over a grassed slope with wood. The flow region is divided into two layers (vegetation layer & soil layer) or three layers (wood layer, vegetation layer & soil layer ...

Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Eradicating invasive predators from islands can result in substantial recovery of seabirds, but the mechanisms that drive population changes remain poorly understood. Meta‐analyses have recently revealed that immigration is surprisingly important to the recovery of philopatric seabirds, but it is not known whether dispersal and philopatry ...

Shuitu Baochi Xuebao, 2011 通过室内模拟降雨试验,研究了不同降雨条件下地面坡度对红壤坡面产流过程和侵蚀过程的影响,结果表明,红壤坡面起始产流时间随坡度的增加有所提前,但不明显,坡面起始产流时间的早晚主要受降雨强度控制;坡面径流量随雨强的增大而增大,随坡度的变化比较复杂,在雨强为50mm/h时,径流量随坡度的增加而减小,在雨强为75mm/h时,径流量随坡度的增加先增大后减小;不同降雨强度下各坡度的侵蚀产沙率都是在降雨初期急剧上升,随后以指数下降,形成一个向左倾斜的曲线。坡度对坡面侵蚀产沙的影响随雨强的增大而增强 ...

Disasters, Volume 48, Issue 3, July 2024.Aid relations in protracted displacement comprise a diversity of actors with different influence and involvement over time. Building on the case of Sri Lanka's northern Muslim's expulsion from the north of the country in 1990, this paper investigates the dynamic space of aid relations in their drawn‐out internal displacement.

Understanding consumers to inform market interventions for Singapore's shark fin trade
People and Nature, Volume 6, Issue 2, Page 733-748, April 2024.Abstract Sharks, rays and their cartilaginous relatives (Class Chondrichthyes, herein ‘sharks’) are among the world's most threatened species groups, primarily due to overfishing, which in turn is driven by complex market forces including demand for fins.

Shuitu Baochi Xuebao, 2016 通过设计2种降雨强度(90，120 mm/h)和4个地表坡度(10°，15°，20°，25°)的模拟降雨试验，研究了降雨强度和坡度对粘黄土坡面片蚀的影响。结果表明，试验条件下当降雨量相同时，降雨强度和坡度对径流量的影响不显著，而对坡面片蚀量的影响非常显著；当降雨强度由90 mm/h增加到120 mm/h时，在相同坡度条件下坡面片蚀量增加76.2%～128.0%；当坡度由10°变化到25°时，90 mm/h和120 mm/h两种降雨强度坡面片蚀量分别增加29.3%～72.1%和1.8%～75.4 ...

Influence of the Rainfall Parameters on the Stability of Landslide Dams [PDF]
, 2014 This study investigates transient seepage using a two-phase flow scheme in finite difference code, FLAC. The saturation of pore water pressure distribution and the stability of the assumed landslide dams are calculated.

Integrative Conservation, Volume 3, Issue 1, Page 76-86, March 2024.Jigme Dorji National Park is the exclusive refuge for the critically endangered Bhutan poppy in Bhutan and worldwide, confined to alpine screes in Tshophu, Tshophu base and Jichudrakey base in Soe gewog, Thimphu. The primary conservation threats to this species stem from harvesting, grazing and trampling by livestock, despite the majority of Bhutan ...
