Dataset Display Service: DMV Minimum Outflow — Corrective Factor (Q) — DGR No.1268/2022

The Minimum Life Flow (DMV) is the instant flow rate, to be determined in each homogeneous section of the watercourse, in order to guarantee the ecological integrity for the protection of aquatic life, to ensure a balanced use of the water resource and to protect the balance of the 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 factor (Q) expresses the dilution requirements of pollutants conveyed in watercourses according to existing human activities and is modulated in a range between 1.00 and 1.60. The Q values are determined on the basis of the periodic update of the state of the surface water bodies.最小生物需水量（Minimum Life Flow, DMV）是指需在河道各均质河段中确定的瞬时流量，旨在保障水生生物保护所需的生态完整性、确保水资源的均衡利用，并维护水体平衡与水文地质平衡。《水保护规划》依据流域片区主管机构制定的相关标准，明确了DMV校正因子的确定与应用方法。因子Q用于表征基于现有人类活动产生的河道污染物稀释需求，其取值范围被限定在1.00至1.60之间。Q值的确定需以地表水体状态的周期性更新结果为依据。
