大型河流流域和洪泛区的水文建模继续受到建模输入和模型校准观测数据的低可用性和低质量的挑战。全球数据集通常用于弥补这一差距，但通常难以获取且耗时，特别是在世界上资源匮乏的地区。许多人呼吁标准化和共享数据，以提高本地盆地建模能力，减少冗余，但仍然存在障碍。我们讨论了数据稀缺地区水文建模的挑战，并描述了一个免费提供的在线工具网站，该网站使用户能够提取任何规模的任何流域的输入数据。该站点将允许用户根据预期应用程序的需要对数据进行可视化、映射、插值和重新格式化。我们使用了赞比西河上游流域和乔比-赞比西河洪泛平原的水文模型来说明这个在线工具集的使用。增加水文建模数据的获取和传播是一项迫切需要，特别是在数据需求和获取继续阻碍当地驱动的水文系统管理的用户中。
Hydrological modeling of large river basins and flood plains continues to be challenged by the low availability and quality of observed data for modeling input and model calibration. Global datasets are often used to bridge this gap, but are often difficult and time consuming to acquire, particularly in low resource regions of the world. Numerous calls have been made to standardize and share data to increase local basin modeling capacities and reduce redundancy in efforts, but barriers still exist. We discuss the challenges of hydrological modeling in data-scarce regions and describe a freely available online tool site developed to enable users to extract input data for any basin of any size. The site will allow users to visualize, map, interpolate, and reformat the data as needed for the intended application. We used our hydrological model of the Upper Zambezi basin and the Chobe-Zambezi floodplains to illustrate the use of this online toolset. Increasing access and dissemination of hydrological modeling data is a critical need, particularly among users where data requirements and access continue to impede locally driven management of hydrological systems.
