Examination of Sakurajima drained sand to beach nourishment materials [PDF]

open access: yes, 2007
本研究では大量に発生した桜島火山灰(流下土砂)のリサイクルを目的とし、養浜材としての応用の可能性を調べたものである。はじめに、桜島火山灰(流下土砂)の土砂としての特性と粒子としての特性を調べた.次に移動床実験を行い、桜島火山灰(流下土砂)を養浜材と仮定し、侵食型・堆積型の波浪を発生させ,地形変化・汀線変化量・前浜勾配等の基礎的な特性量を観察した.以上より桜島火山灰(流下土砂)は養浜材としてリサイクル可能であると結論付けた。Under an aim for recycling of Sakurajima ...

Pea gravel envelopes for tile drains in Coachella Valley

open access: yesCalifornia Agriculture, 1967
The average water application on the 60,000 acres being farmed in Coachella Valley is about seven acre-feet per acre per year. Infiltration rates are high, especially on the high ground.

Modeling the cyclic response of trunk-root-soil systems under lateral loads in sand

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Dynamic response of the trunk-root-soil system is pivotal under wind-induced lateral loads in vegetated regions, especially with the increasing frequency of typhoon events driven by climate change. Existing research has focused on lateral behavior of the

Gaps in the landscape

open access: yesBulletin KNOB
Around 2000 years ago peat was present on a vast scale throughout the Dutch lowlands. Over the course of time, however, peat extraction and post-reclamation subsidence led to the disappearance of large volumes of peat. A quarter of the Netherlands ended

What Is Beyond Hyperbola Detection and Characterization in Ground-Penetrating Radar Data?—Implications from the Archaeological Site of Goting, Germany

open access: yesRemote Sensing
Hyperbolae in radargrams are caused by a variety of small subsurface objects. The analysis of their curvature enables the determination of propagation velocity in the subsurface, which is important for exact time-to-depth conversion and migration and ...
