Large-scale and dynamic surface water mapping is crucial for understanding the impact of global climate change human activities on distribution resources. Remote sensing imagery has become primary data source due to its high spatiotemporal resolution wide coverage. However, reliability current products during flood seasons limited influence clouds optical remote images. Moreover, annual seasonal cannot capture intra-month variations bodies. To address these challenges, we proposed a framework Google Earth Engine that combines multi-source data. Our can generate 10 m spatial maps at 15-day time step.

Intertidal mudflats are an important component of the coastal geomorphological system at interface between ocean and land. Accurate up-to-date mapping intertidal topography high spatial resolution, tracking its changes over time, essential for habitat protection, sustainable management vulnerability analysis. Compared with ground-based or airborne terrain mapping, satellite-based waterline method is more cost-effective constructing large-scale topography. However, accuracy affected by extraction waterlines calibration height. The blurred boundary turbid water in tide-dominated estuary brings enormous challenges accurate extraction, errors estuarine level simulations prevent direct heights. To address these issues, this paper developed a novel deep learning using parallel self-attention mechanism boundary-focused hybrid loss to extract accurately from dense Sentinel-2 time series. UAV photogrammetric surveys were employed calibrate heights rather than simulated levels, such that error propagation constrained effectively.

Remote sensing plays a crucial role in modeling surface water quality parameters (WQPs), which aids spatial and temporal variation assessment. However, existing models are often developed independently, leading to uncertainty regarding their applicability. This study focused on two primary objectives. First, it aimed evaluate different for chemical oxygen demand (COD), total phosphorus (TP), nitrogen (TN), suspended solids (TSS) body, the J. A. Alzate dam, Mexican highland region (R2 ≥ 0.78 RMSE ≤ 16.1 mg/L). The were estimated using multivariate regressions, with focus identifying dilution dragging effects inter-annual flow rate estimations, including runoff from precipitation municipal discharges. Second, sought analyze potential scope of application these other bodies by comparing mean WQP values. Several exhibited similarities, minimal differences values (ranging −9.5 0.57 mg/L) TSS, TN, TP. These findings suggest that certain may be compatible enough warrant exploration joint future research endeavors.
