Risk — TRI Loir — Isocote lines for a height of water of 1.15 m at La Chartre en 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).

等淹水高度线表（isocote lines，即表征洪水期间水体抵达海拔高度的等值线）。
该空间数据集由……的地理信息系统（Geographic Information System, GIS）高洪水风险土地洪水指令（TRI）生成，并为适配欧盟洪水指令的报告需求完成制图。
2007年10月23日发布的欧盟第2007/60/EC号指令《关于洪水风险评估与管理》（刊载于2007年11月6日第L288号官方公报（Official Journal, OJ），第27页），对欧盟境内的洪水防控战略具有深远影响。该指令要求编制洪水风险管理计划，以降低洪水对人类健康、自然环境、文化遗产及经济活动造成的负面影响。
相关目标与实施要求已在2010年7月12日颁布的《国家环境承诺法》（LENE）以及2011年3月2日颁布的政令中予以明确。在此框架下，针对IRRs的洪水与洪水风险制图工作的核心目标，是通过统一并客观化洪水暴露相关认知，助力洪水风险管理计划（WRMs）的编制。
本数据集可用于生成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。其目标是提供量化依据，以进一步评估某一区域在高、中、低三种洪水发生概率下的脆弱性。
