Focus on the classification history Some of the earliest classification of water inrush according to geological features originated from the perspective of mining science. Gao (1999) seems to have been the first to distinguish between the various types of water inrush in coal mines: exposure of ...
On the western flank of the Murzuq Basin the Assedjefar Formation is mappable from Tikiumit to South Anay. The thickness ranges from 140m in the Hasi Anjiwal area to 50 m at Anay reflecting a gradual change from a clastic section in the north to a more calcareous facies in the south....
In this work, we aim to verify the predictions of the numerical simulators, which are used for designing field-scale hydraulic stimulation experiments. Alt
The longitudinal slope of rock fishways was highly variable but there was a slight but non-significant trend toward flatter slopes over time, from 1 V:20H (5% gradient) in the early 1990s to 1 V:30H (3.3% gradient) in late 2023 (Fig. 3A). The construction (excluding design) costs wer...
To avoid confounding by slopes parallel to the barriers,we selected a segment of the barrier system on a near 0% north to south slope for the ... JK Aase,JL Pikul - 《Journal of Soil & Water Conservation》 被引量: 33发表: 1994年 Delineating the major landforms of catchments using an...
The estimated effective porosity for the AEB_IIIG reservoir ranges from 12 to 17% (Fig. 4c). The formation-water resistivity in the interval of interest was determined using Pickett's plot, yielding a value of 0.016 Ohm.m (Fig. 5). The utilization of water resistivity and deep resistivity...

The YouTube video https://www.youtube.com/watch?v=kVNkt7WUD6I by the Swiss company Geobrugg shows the types of barriers constructed to protect against such rockfalls and a test of one boulder bouncing down a slope into a barrier. The COR and slope contour can have an important effect ...
In the Swiss concept, the canister is placed on a bed of highly compacted bentonite blocks, and the upper part is filled with bentonite pellets. In an earlier Belgian concept, the canister was planned to be surrounded by clay-rich blocks. This barrier should be separated from the plastic ...
Additionally, snow melt on North-facing rock slopes tends to form a basal ice layer under the snow pack in spring, largely preventing the infiltration of melt water (Phillips et al. (2016)). After the 2017 failure, first-hand observations via telescope confirmed small patches of ice in the...
