Applicability of Geomorphic Index for the Potential Slope Instability in the Three River Region, Eastern Tibetan Plateau. [PDF]

Sensors (Basel), 2021
Geomorphic indices (e.g., the normalized channel steepness index (Ksn) and the stream length-gradient index (SL)) highlight changes in fluvial shapes and gradients. However, the application of these indices was seldom used to identify potential landslide zones.

Remotely sensed mid-channel bar dynamics in downstream of the Three Gorges Dam, China [PDF]

, 2020
The downstream reach of the Three Gorges Dam (TGD) along the Yangtze River (1560 km) hosts numerous mid-channel bars (MCBs). MCBs dynamics are crucial to the river’s hydrological processes and local ecological function.

3D Inundation Mapping: A Comparison Between Deep Learning Image Classification and Geomorphic Flood Index Approaches

Frontiers in Remote Sensing, 2022
Inundation mapping is a critical task for damage assessment, emergency management, and prioritizing relief efforts during a flooding event. Remote sensing has been an effective tool for interpreting and analyzing water bodies and detecting floods over the past decades.

Delineation of flood‐prone areas in cliffed coastal regions through a procedure based on the geomorphic flood index [PDF]

Journal of Flood Risk Management, 2021
AbstractThe geomorphic flood index (GFI) method provides a good representation of flood‐prone areas. However, the method does not account for floodwater transfers in undefined interbasins (UIBs), which represent intercluded small basins along the coastline likely to be flooded by adjacent major rivers.

Impact of Geomorphic Variables on Dissection Index in Western Doon of Dehra, Uttarakhand, India

Journal of Geography, Environment and Earth Science International, 2023
Dissection Index is a scale of measure of degree of roughness of the earth surface. The degree of roughness of earth surface is consolidated outcome of morphometric elements like – average slope, relative relief, absolute relief, drainage density and lithology. The dissection index is very useful variable in the study of the terrain.

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.

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.
