When I first started studying geomatics engineering, geoinformatics, geography, and environment, I didn’t imagine I would one day spend hours looking at rivers from space. My interest in rivers began much earlier, long before academic papers, coding notebooks, or satellite imagery, when I grew up surrounded by mountains, streams, and seasonal floods in Nepal. Rivers were never abstract to me. They shaped livelihoods, agriculture, and sometimes disasters. Over time, as I moved through formal education and eventually into research, I realized that rivers are not just physical features on a map; they are living systems constantly responding to climate, vegetation, and human decisions. That realization led me to ask a simple question: How do rivers change over time, and how can we measure those changes objectively? In my recent research, I used satellite imagery and GIS to track how river channels migrate over years and decades. Instead of relying on one-time field observations, satel...
