Water Resources Management

To assess the eutrophication of urban water bodies, NDCI derived from Sentinel 2 imagery was used. The high-resolution 20-meter Red Edge band allows for accurate rankings of the state of the water bodies, which are particularly vulnerable to urban waste. More info

Cropland was analyzed using false composite images of amplitude, phase, and max-NDVI values. The map shows the croplands in Ninh Thuan during 2018 as colored pixels with high phase and amplitude, while non-croplands are represented as grey/dark pixels with low phase/amplitude. More info

I coordinated a multidisciplinary team to assess how hydropower operations in the Xekaman River Basin affect river flows, ecosystems, and local communities. The goal was to find a balance between energy generation and the health of the river system, following international good practice on environmental and social safeguards.

Our work showed that, in places where water is diverted, the river channel can become almost dry—leaving only scattered pools and very limited habitat for aquatic life (photo). These findings highlight the importance of managing flow releases and tributary inflows so that rivers can continue to support biodiversity and provide water for people downstream. By bringing together hydrological analysis, ecological knowledge, and community perspectives, we developed practical recommendations to help guide more sustainable water management in the basin.

Flood risk assessment (FRA) plays a vital role in planning and development, helping identify areas vulnerable to flooding and guiding the design of effective mitigation measures. (Photo: Using SAR Sentinel-1 satellite data, I analyzed 135 images from 2016–2020 to create a water occurrence map of the project site. This map reveals the site’s flood history and patterns, providing valuable insights for managing risks and making informed decisions about future development.
