DEM-based analysis of tectonic geomorphologic characteristics and tectonic activity intensity of the Dabanghe River Basin in South China Karst

Open Geosciences, 2023
The Dabanghe River Basin, in the west of Guizhou Plateau, consists of numerous prominent geological structural features, such as the Shuicheng–Wangmo, Yadu–Ziyun, and Yongningzhen Faults, the Huangguoshu Waterfall, and the Guanjiao Knickpoint.

Evidence of Quaternary tectonics along Río Grande valley, southern Malargüe fold and thrust belt, Mendoza, Argentina [PDF]

, 2019
The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous.

Geomorphic indexing of landslide dams evolution

Engineering Geology, 2016
AbstractLandslide dams are rather common events in hilly and mountainous areas and they occur when a landslide reaches a valley floor closing the riverbed. If they form a lake basin, unstable landslide dams can have catastrophic consequences when they occur in upstream of populated regions.

Investigation of the watershed hydro-morphologic characteristics through the morphometric analysis: A study on Rayeng basin in Darjeeling Himalaya

Environmental Challenges, 2022
The analysis of morphometric parameters gives a precise scenario about the geomorphic characteristics and the hydrological behaviour of a drainage basin, especially in the areas where hydrological data are unavailable due to the absence of a gauging ...

Quantifying Anthropogenic Interventions in Yamuna River Through River Flow Health Index and Geomorphic Analysis

, 2023
Abstract The study deals with the flow alterations and planform adjustments due to the construction and operation of barrages in Yamuna River, India. The flow alterations are quantified using the River Flow Health Index on a 0–1 scale. The planform adjustments are analyzed using satellite-generated geomorphic maps.

Modified geomorphic flood index (GFI) method on backwater problem in tidal tropical river for rapid flood assessment

IOP Conference Series: Earth and Environmental Science, 2023
Abstract The Geomorphic Flood Index (GFI) model can show flood inundation in a watershed based on flood events. Flood inundation can occur because of the backwater effect in the river channel. The different water levels from the river and tide that occur downstream may temporarily disturb the water depth and flow velocity.

Assessment of the geomorphic indices in relation to tectonics along selected sectors of Borpani River Basin, Assam using Cartosat DEM data

Geosystems and Geoenvironment, 2022
We studied geomorphic indices related to tectonics along the Borpani River using Cartosat 10 m spatial resolution Digital Elevation Model (DEM) data. A total of 11 geomorphic indices such as transverse topographic symmetry factor (Tt), drainage basin ...
