Our lab has developed a 1 km resolution streamflow simulation for all of Thailand, aimed at improving water resource management, agricultural planning, and climate applications. This simulation offers detailed, high-resolution data for even the most remote, ungauged areas where traditional measurements are not available, providing a comprehensive and current view of streamflow patterns nationwide. Continuous updates make it an invaluable resource for managing water resources, forecasting agricultural needs, and evaluating climate impacts. This readily accessible information supports better decision-making, assists with flood warnings, and enhances overall resource management. By making high-quality hydrometeorological data available, our approach ensures more precise and timely responses to environmental challenges at both local and national levels.

Figure 1: A high-resolution, detailed view of streamflow dynamics across Thailand, illustrating how flow patterns evolve over time with exceptional clarity. The 1 km resolution captures fine-scale variations in streamflow that are often missed in coarser-resolution models, offering significant benefits for precise water resource management, accurate flood risk assessment, and targeted agricultural planning. By revealing intricate flow details, this animation enhances the ability to make informed decisions and respond effectively to changes in hydrological conditions.

High-resolution streamflow data is essential for understanding and managing water resources effectively. It gives a clear and detailed view of how water flow changes across different areas and over time. This detailed information helps in managing water supplies, assessing flood risks, and planning agricultural activities more accurately. It allows for precise predictions and timely actions by revealing local patterns and changes that might be missed with coarser detailed data.

Our development of a 1 km resolution streamflow simulation for Thailand represents a significant advancement in this context. While many studies offer high-resolution data, they are often confined to specific projects, limited to certain basins, or are discontinuous and not publicly accessible. In contrast, our nationwide dataset provides continuous, high-resolution coverage across the entire country, offering a comprehensive and up-to-date view of streamflow patterns. This broad and consistent availability fills a critical gap left by existing data sources, democratizing access to detailed hydrometeorological information. By offering a complete picture of streamflow dynamics at a national level, our data supports more effective and informed decision-making for water resource management, flood risk mitigation, and agricultural planning, making it a valuable and novel resource for stakeholders across Thailand.
