Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

A Bio-Wicking System to Mitigate Capillary Water in Base Course [PDF]

, 2016
Water within pavement layers is the major cause of pavement deteriorations. High water content results in significant reduction in soil’s resilient behavior and increase in permanent deformation. Conventional drainage systems can only drain gravity water

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Evaluating Erosional Stability of Reconstructed Mine Landscapes Using Landform Evolution Models: Parameterisation and Decadal‐Scale Erosion Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Ensuring the long‐term erosional stability of post‐mining landforms remains a major challenge in open‐pit mining. Reconstructed landscapes must support the agreed post‐mining land use, such as cattle grazing in the Hunter region of southeastern Australia, requiring stable pasture and minimal soil loss.

Investigation of durability of geotextiles tubes in marine conditions [PDF]

E3S Web of Conferences
Geotextile tubes are widely used in coastal protection structures like revetments, breakwaters, and containment bunds. Geotextile sheets that make up the tube are exposed to harsh environmental conditions, such as UV radiation and wave action.

Determining Geotextile Effects on Bearing Capacity Ratio and Cost of Pavement Layers by Conducting CBR Tests

Journal of Natural Fibers, 2022
In this study, California Bearing Ratio (CBR) tests in a laboratory were performed to observe the effects of geotextiles on bearing capacity ratio, pavement layer thickness, and cost for geotextile reinforced soils.

Permeability Testing for Geotextile and Geotextile/Soil Systems

Proceedings of geotextile symposium, 1986
The permeability properties of geotextiles and geotextile/soil systems were studied using gradient ratio testing apparatus improving on the type of U. S. Army Engineer Waterways Experiment Station.It is suggested that the permittivity is better than permeability to evaluate the characteristics of geotextiles as filter materials. From the results on six

Catchment conversion to agriculture alters freshwater macroinvertebrate community responses to flow disturbance: results from a replicated in‐stream experiment

Oikos, EarlyView.
Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

A study on soil-geotextile interaction using gradient ratio tests

Przegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2019
Nonwoven geotextile have been widely used for filtration. In this paper, the clogging potential for a soil-geotextile system were assessed using laboratory tests. An ASTM modified gradient ratio test device was used to determine gradient ratio as well as
