I am currently working on my MSc. Dissertation on the recent GLOF disaster which occurred in my state. Even with literature review I am unable to understand the methodology and process of the analysis.
I know that I require the river volume=Area * Depth.
How should I go about getting the area and depth, would it require the use of Dem?

Calculate River Area: Using GIS tools, calculate the area of the river channel within the delineated basin. This involves determining the total area of the cells or pixels that represent the river channel in the DEM. Estimate River Depth: To estimate the depth of the river, you'll need additional data such as water level measurements. If available, use field measurements or remote sensing data (e.g., satellite imagery) to determine the water level at various points along the river. Then, subtract the elevation of the riverbed (from the DEM) from the water level to obtain the depth.
