Hydrogeological feasibility of mine water deep geological storage in Baotashan coarse sandstone: A case study in Ordos Basin

open access: yesDeep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022
We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...

Deglaciation history and subsequent lake dynamics in the Siljan region, south‐central Sweden, based on new LiDAR evidence and sediment records

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3515-3545, December 2022., 2022
Glacial geomorphology and postglacial landforms, derived from LiDAR‐based digital terrain models, together with radiocarbon‐dated sediment sequences, form the basis for landscape reconstruction spanning c. 2000 years (10,500–8500 cal. bp). After formation of streamlined terrain and ribbed moraine tracts followed intense glaciofluvial activity at ...
