This document summarizes a technical seminar on remote sensing applications for water resource management. The seminar covers an introduction to remote sensing, a literature review on its uses in measuring surface water, soil moisture, and evapotranspiration. It then outlines the objectives, a case study on the early development of radar imaging, advantages and disadvantages of remote sensing techniques. The conclusion discusses the potential of earth observation data in water management and challenges in integrating remote sensing with water resource specialists.
