Flood Plains

The flood plains indicate the area of land inundated by runoff in a storm event that has a 1 percent or greater probability of occurring in any given year, assuming maximum probable development (MPD) and future climate change. The flood plains are mapped from hydraulic modelling results. Information specific to each flood plain is accessible using the Identify tool, including the flood report. This dataset is continually updated at catchment scale to reflect the best information available. This dataset is updated by the Heathy Waters team on a regular basis. Disclaimer: In using the Catchments and Hydrology data set, you acknowledge that you have read, understood and agreed to the disclaimers below. The flood plains and flood sensitive area data layers are generated from catchment level modelling based on the datasets, requirements and technology available at the time of model build. They are compiled regional layers with varied data uncertainty and currency, which may directly impact data accuracy for the area of interest. The information provided therefore does not preclude the need for appropriate site-specific assessment and cannot be construed as an endorsement or approval of any development by Auckland Council. The Catchments and Hydrology data set is updated regularly when new information becomes available. As such, downloading and copying activities may result in data invalidity. Whilst due care has been taken in producing the Catchments and Hydrology data sets, Auckland Council gives no warranty as to the accuracy and completeness of any information given and accepts no liability for any error, omission or use of the information.本数据集所界定的漫滩，指在假设采用最大可能开发（Maximum Probable Development, MPD）情景并考虑未来气候变化的前提下，任意一年发生概率不低于1%的暴雨径流淹没区域。该漫滩数据基于水力模型模拟结果绘制而成。可通过识别工具（Identify tool）调取每一处漫滩的专属信息，其中包含洪水报告。本数据集以流域为单元持续更新，以纳入当前可获取的最优信息。本数据集由Heathy Waters团队定期更新。免责声明：使用《流域与水文学》数据集前，请确认您已阅读、理解并同意以下免责条款。漫滩与洪水敏感区数据图层基于模型构建当时可获取的数据集、技术标准与需求，通过流域尺度建模生成。上述区域图层由多源数据整合而成，存在不同程度的数据不确定性与时效性差异，可能直接影响目标区域的数据精度。因此，本数据集提供的信息并不替代必要的场地专属评估，也不应被视为奥克兰议会（Auckland Council）对任何开发项目的背书或批准。《流域与水文学》数据集将在获取新数据后定期更新。因此，下载或复制该数据集的行为可能导致数据失效。尽管奥克兰议会在编制《流域与水文学》数据集时已尽合理审慎义务，但不对所提供信息的准确性与完整性作出任何担保，且不承担因信息错误、遗漏或使用该信息而产生的任何责任。
