Climate change and human activities are the main threats to ma- rine, estuarine and riverine environments, making effective mon- itoring essential. This study uses DIY single-beam echosounders with Sentinel-2 satellite imagery to create Satellite Derived Ba- thymetry (SDB) models in sedimentary zones. The 2023-2024 campaigns in the Ebro Delta and the Mequinenza and Riba-roja reservoirs demonstrate the feasibility and cost-effectiveness of these methods to observe morphological changes. Combining DIY technologies with satellite data, we can develop accessible and sustainable approaches to study and protect vulnerable aquatic environments.
