Map Viewing Service (WMS) of the dataset: Risk — TRI Loire aval — Isocote lines for a water height of 5.80 m in Loir-et-Cher

Table of isocote lines (level curves representing altitudes reached by water during flooding). Spatial data set produced by the GIS High Flood Risk Land Flood Directive (TRI) of... and mapped for reporting purposes for the European Flood Directive. European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe. It requires the production of flood risk management plans to reduce the negative consequences of flooding on human health, the environment, cultural heritage and economic activity. The objectives and implementation requirements are set out in the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. In this context, the primary objective of flood and flood risk mapping for IRRs is to contribute, by homogenising and objectivating knowledge of flood exposure, to the development of flood risk management plans (WRMs). This dataset is used to produce flood surface maps and flood risk maps that represent flood hazards and issues at an appropriate scale, respectively. Their objective is to provide quantitative evidence to further assess the vulnerability of a territory for the three levels of probability of flooding (high, medium, low).等淹高线表（即表征洪水期间水体淹没高程的等值曲线）。 本空间数据集由……的《高洪水风险土地洪水指令》（TRI）对应的地理信息系统（Geographic Information System, GIS）生成，并为符合《欧洲洪水指令》的报告要求开展制图工作。 2007年10月23日发布的欧盟指令2007/60/EC《关于洪水风险评估与管理的指令》（官方公报L 288，2007年11月6日，第27页）影响了欧洲的洪水防治战略，该指令要求制定洪水风险管理计划，以减轻洪水对人类健康、自然环境、文化遗产及经济活动造成的负面影响。 该指令的目标与实施要求已在2010年7月12日发布的《国家环境承诺法》（LENE）以及2011年3月2日发布的政令中予以明确。在此框架下，针对IRRs区域的洪水与洪水风险制图工作的核心目标，是通过统一洪水暴露相关认知标准并实现其客观化，助力洪水风险管理计划（WRMs）的制定。 本数据集可用于制作洪水淹没范围图与洪水风险图，二者分别以适宜比例尺表征洪水灾害与相关风险。其核心目标是提供量化依据，以针对高、中、低三级洪水发生概率，进一步评估区域的洪水脆弱性。
