Dataset Direct Download Service (WFS): Reference profiles for the flooding of the centennial flood of Orconté — Orconte sector in Frignicourt

During hydraulic modelling, the centennial flood hazard was determined on the area. In addition to the envelope of this hazard, the water levels over the entire sector could be determined. In order to visualise these water heights, a set of profile, known as “reference profiles”, was positioned with an altimeter deviation of about 25 cm. All of these ratings are linked to the General Level of France and are expressed in NGF meter.

Genealogy: The reference profiles are represented on the graphic documents. They are represented by open polylines with a rating in NGF meter. These ratings will determine the regulatory ratings used in the interpretation of the future IPP Regulations. The profiles are located throughout the PPRi sector.

水力模型（hydraulic modelling）构建期间，已针对该区域确定百年一遇洪水风险。除该风险的包络线外，还可获取整个片区的水位高程数据。为可视化展示这些水位高程，布设了一组参考剖面（reference profiles），其布设高程的偏差约为25厘米。所有上述高程值均关联法国国家高程基准（NGF），单位为NGF米。
溯源信息：参考剖面绘制于图文文档中，以带有NGF米高程标注的开放多段线（open polylines）表示。上述高程值将作为解读未来IPP法规时所采用的法定判定高程依据。该剖面覆盖整个PPRi片区。
