Abstract

The Small Geographically Isolated Wetlands (AUGIs) are hydrogeomorphological targets characterized by depressions surrounded by topographical elevations, with no visible connectivity to other water bodies. However, they play an important role in the local to regional hydrological cycle, such as the storage of surface water. Predominantly located in the Paulista Peripheral Depression and Cuesta, AUGIs are crucial for maintaining regional water availability, but they are still poorly understood, especially regarding the quantification of stored water. This project aims to quantify the water storage capacity of AUGIs in the Corumbataí River Basin through the development of an innovative methodology based on advanced geospatial technologies, such as LiDAR sensors, sonar embedded in drones, and multispectral imagery. The use of these technologies will allow for accurate mapping of the microtopography of AUGIs and the generation of high-resolution digital elevation models. Expected results include quantitative data on the volume of water stored in these areas and their contribution to regional water management. This information is essential to support public policies focused on the conservation and sustainable management of AUGIs, which are crucial for regional water security and environmental preservation.
