[takes me back to my engineering geology days in the Southern Hemisphere, including my thesis – with a healthy dose of spatial analysis and modeling – and all with a specific use; what is not to like?]

photo - terraces in part of the Ticsani Valley, Peruphotos - (A) The main fluvial landforms in the AOI. The Carumas river can be seen here to be bounded by landslides affecting a fluvial terrace covered by agricultural terraces. (B) Landslides affecting a slope close to a community in the AOI. Note the construction of terraces on prior landslide deposits.schematic / cross-section - Typical profile of terraces built in Southern Peru. Wall rocks are directly piled over an excavated trench in bedrock without mortar. An upward decreasing gradation is used to fill the internal portion of the wall in compacted layers. Fertile arable soil is placed in the top 30 cm.imagery / map / schematic cross-section - (A) A 3D view of the San Cristobal landslide. (B) A 1:50,000 geological map of the landslide area, modified from [33]. Ki-mat = Matalaque Fm. P-Pi = Puno Fm. Q-pl = colluvial deposits, debris avalanche. Qp-vl-pi = pyroclastic deposits. Red line marks the topographic cross-section shown in A. (C) Cross-section of the San Cristobal landslide with estimated base groundwater conditions (blue) and materials boundaries (green) to be used for modeling and interpreted potential failure surfaces (dashed red).

Permeability (Earth sciences) (Hydrology 💧)

Permeability in fluid mechanics and the Earth sciences is a measure of the ability of a porous material to allow fluids to pass through it.

A new walking and cycling link in Knocklyon has hit a big grey wall. It separates Two Oaks, a just-built 590-home apartment complex, from the council’s grassy Dargle Park, and older area housing estates. #Dublin #Ireland #cycling #walking #activetravel #permeability
