Analysis of dynamic change of Hongjiannao Lake based on MNDWI

IOP Conference Series: Earth and Environmental Science, 2017
In order to understand recent changes in inter-annual trends in water area of Hongjiannao Lake and to explore influence factors affecting the changes, the Landsat data during the year from 1988 to 2014 was processed by Modified Normalized Difference Water Index (MNDWI) and the water body boundary of Hongjiannao Lake was extracted.

Detection of Changes in Surface Water Bodies Urban Area with NDWI and MNDWI Methods [PDF]

International Journal on Advanced Science, Engineering and Information Technology, 2019
Land surface water bodies, an essential part of the Earth’s water cycle such as rivers, lakes, swamp, and reservoirs, influence the global ecosystem and climate global significantly. Makassar, one of the most populated cities in Indonesia, recently experiences massive development that affects the existence of vegetation area and urban aquatic ecosystem.

Monitoring of drainage system and waterlogging area in the human-induced Ganges-Brahmaputra tidal delta plain of Bangladesh using MNDWI index

Heliyon, 2023
Waterlogging is one of the major global problems which affects agro-economic activities around the world. In the coastal areas of Bangladesh, especially the southwestern coast, drainage congestion and waterlogging are very common which makes the area uninhabitable.

Utilizing NDWI, MNDWI, SAVI, WRI, and AWEI for Estimating Erosion and Deposition in Ping River in Thailand

Hydrology, 2023
The Ping River, located in northern Thailand, is facing various challenges due to the impacts of climate change, dam operations, and sand mining, leading to riverbank erosion and deposition. To monitor the riverbank erosion and accretion, this study employs remote sensing and GIS technology, utilizing five water indices: the Normalized Difference Water

MNDWI and BSI for Monitoring Land Degradation in Gresik Regency

IOP Conference Series: Earth and Environmental Science
Abstract Land degradation or land productivity declined in Indonesia, reaching 25.1% in 2014. However, in East Java, land degradation showed a downward trend from 2006 to 2018. This land degradation process was expected to affect the condition of agriculture and plantations in the region.

Fluvio-geomorphic change of the Padma-Meghna river course using the NDWI and MNDWI techniques

Water Science
Abstract This study intends to investigate the fluvial-geomorphic change and erosion-accretion processes of two significant rivers. The 2149 km2 research area's overall erosion and accretion were depicted using multi-temporal Landsat images and NDWI, MNDWI methods to measure and investigate change.
