Some geomorphic indices in the North Central Vietnam

Geosciences Journal, 2021
We have applied geomorphology to investigate the tectonic fault in the North Central Vietnam. At the local scale, the active tectonic possibility of fault zones in the study area is geomorphologically assessed for the first time. The results show the geomorphic indices of drainage basin asymmetry (AF = 0–34), valley floor width-to-height ratio (Vf = 0 ...

Neotectonics from Geomorphic Indices: Highlights from Main Mantle Thrust (Pakistan)

Geotectonics, 2021
The collision of the Eurasian and Indian plates has resulted in two spatially offset subduction zones, the Makran subduction zone to the south and the Himalayan convergent margin to the north. The Main Mantle Thrust (MMT) and adjoining regions have a complex geomorphic setting and geological variations with a number of active faults that were connected

Possible geomorphic indicators of methane emission in three Martian impact craters

2022
<p>Methane has been detected these last years in the Martian atmosphere both from orbit (TGO-ExoMars mission - still active) and from ground (Curiosity rover – Mars Science laboratory mission). The sources of methane remain undetected.

Hydrologic, water quality and geomorphic indicators of catchment Effective Imperviousness

Australasian Journal of Water Resources, 2008
Recent research has related waterway ecosystem health to a simple composite indicator of catchment Effective Imperviousness (EI). EI is defined as the impervious area that is directly connected, via a stormwater pipe or channel, to receiving waters. Empirical evidence has shown that catchments with EI greater than 5% have a significant impact on stream

Analytical Estimation of Geomorphic Discharge Indices for Small Intermittent Streams

Journal of Hydrologic Engineering, 2016
AbstractEffective, f-load, and functional-equivalent discharges are metrics that can be used as design flows for stream channel restoration and for eco-hydrologic and geomorphic studies. Previously published analytical estimators of these discharge indices are reviewed and new estimators are derived for gamma, lognormal, mixed gamma, and mixed ...

River reorganization based on geomorphic indices in the Huashan Mountains, central China

2022
<p>In many mountainous regions on Earth, strong spatial variations in uplift with a fault-bounded transition from uplift to subsidence drive the coevolution of high mountain topography and adjacent low-lying basins. In this study, we investigate which topographic patterns are characteristic for such a geodynamic setting where actively ...

Geomorphic indications of contour map inaccuracy

Cartography, 1967
In Volume 6, No. 2, of this journal Jennings (May, 1967) discussed the geomorphologist's use of maps in general. One very interesting example of map use that highlights the relationship between geomorphology and cartography is provided by the “morphometric methods”.
