[EN] This research presents a new drillability value (SJ*) that corrects the most-used Sievers¿ J-value (SJ) by removing the accommodation effect of the drill bit in the first tenths of a millimetre to better represent the ...
[EN] Sediment budgets and morphological channel adjustments are closely related to changes in stream power. In ephemeral channels, whose geomorphic response depends on the magnitude and frequency of hydrological events ...
[EN] Stream power represents the rate of energy expenditure along a stream reach and can be calculated using topographic data acquired via structure-from-motion (SfM) photogrammetry and terrestrial laser scanning (TLS). ...
[EN] Groundwater is a vitally important resource for humans. One of the main problems derived from the overexploitation of
aquifers is land subsidence, which in turn carries other associated natural risks. Advanced ...
