"impact pressure"

One of the major concern for the gas sequestration/storage feasibility in natural underground formations is the assessment of the sealing efficiency of the low-permeable sequences overlying potential storage formations. The sealing efficiency is quantified via the threshold pressure and/or residual pressure difference parameters; the experimental laboratory procedures for their evaluation have been widely...


When major accident scenarios are considered, the effects of major events which give rise to a serious, immediate or deferred danger to human health or the environment, inside or outside the production or storage area due to the presence in high quantities of one or more dangerous substances are being considered. Events of this type, except in exceptional cases, have always had important consequences...


Debris flow events are known today as one of the most dangerous natural hazard events due to the elevated impact pressures they can reach. Depending on its intensity, a debris flow has the capacity to flatten forests and carry along the tree trunks, to completely demolish buildings and consequently to create a great risk to human life.

However,...


Crossing hydrogeological and ecological sensitive aquifers, water ingress can occur, which can lead to irreversible damage to hydrogeological and ecological systems. In order to avoid this, the rock mass surrounding these hydrogeological sensitive tunnel sections is sealed by injections to reduce the hydraulic permeability, the water inflows and consequently the regional water level drawdowns. In deep tunnels, complete sealing is not possible due to the high water pressures.
Residual water volumes will continue to enter the tunnel. The magnitude...

The rapid erosion of alpine valleys can be prevented by torrential barriers. For their design is crucial the thrust acting upon them due to earth and water pressures. From the evaluation of damage events and field investigations it can be inferred that often no water saturation and thus not the full hydrostatic pressure acts upon such barriers. The uncertainty associated herewith is reflected in various guidelines. The field observations can be explained by the structure of the
backfill but also by the distribution of the water pressure. An...

CiteScore:
2020: 3.8
CiteScore measures the average citations received per peer-reviewed document published in this title.
CiteScore values are based on citation counts in a range of four years (e.g. 2016-2019) to peer-reviewed documents (articles, reviews, conference papers, data papers and book chapters) published in the same four calendar years, divided by the number of these documents in these same four years (e.g. 2016 —19).
Source Normalized Impact per Paper (SNIP):
2019: 1.307
SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SCImago Journal Rank (SJR)
2019: o.657
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal's impact.
Journal Metrics: CiteScore: 1.0 , Source Normalized Impact per Paper (SNIP): 0.381 SCImago Journal Rank (SJR): 0.163
