Minimum Vital Outflow DMV — Corrective Factor (Q) — DGR No 609/2018

The Minimum Vital Outflow (DMV) is the instantaneous flow rate, to be determined in each homogeneous stretch of the watercourse, in order to guarantee ecological integrity for the protection of aquatic life, to ensure a balanced use of the water resource and to protect the balance of water and hydrogeological balance. The Water Protection Plan identifies the methods for determining and applying the corrective factors of the DMV on the basis of the criteria identified by the District Basin Authorities. The parameter (Q) expresses the dilution needs of pollutants conveyed to watercourses according to existing anthropogenic activities and is modulated in a range between 1,00 and 1,60 by assigning values based on the status of surface water bodies classified with Presidential Decree No 11/2016. For the area of competence of the F. Magra Basin Authority, please refer to the Excerpt Plan for the Protection of Watercourses affected by derivations approved by DCR No 15/2001.最小必要流量（Minimum Vital Outflow，DMV）指需在河道各均质河段内确定的瞬时流量，其设立目的为保障水生生物保护所需的生态完整性、确保水资源的合理均衡利用，同时维护水体与水文地质的平衡状态。 水保护计划（Water Protection Plan）明确了基于区域流域主管部门（District Basin Authorities）所定标准，开展DMV修正系数确定与应用的具体方法。 参数（Q）用于表征依据现有人类活动排入河道的污染物稀释需求，其取值被调控于1.00至1.60的区间内，具体数值根据第11/2016号总统令划定的地表水水体等级确定。 针对马格拉河流域管理局（F. Magra Basin Authority）的管辖范围，请参阅由第15/2001号DCR批准的《受引水影响河道保护摘录方案》。
