Ökohydrologisch begründete Mindestabflüsse für Durchflusspegel an berichtspflichtigen natürlichen und erheblich veränderten Fließgewässer-Oberflächenwasserkörpern

The ecologically justified minimum runoff (Qmin,ök) describes the minimally necessary outflow to ensure the good status of the biological quality components macrozoobenthos and/or fish plausibilised with the quasi-natural or measured low-water requirement for the 1991-2015 series, but without taking into account other interests or special natural conditions of the catchment area. The Qmin,ök value is based on the ecologically justified minimum water management (Qök) and also takes into account natural branches of the waters for the flow levels. For comprehensibility of the calculations and comparisons, the level-specific values of the intermediate steps are listed in the attribute table of the shape. Please note the documentation as well. The ecologically justified minimum outflows were determined only for flow levels of natural and significantly altered flow water bodies. No minimum water requirement is levied for artificial water bodies from an ecological point of view.生态合理最小径流量（ecologically justified minimum runoff, Qmin,ök）指为保障大型底栖无脊椎动物（macrozoobenthos）和/或鱼类的生物质量组分处于良好状态所需的最小出流量，该值依托1991-2015年序列的准天然或实测枯水需求完成合理性验证，但未纳入流域的其他利益诉求或特殊自然条件。Qmin,ök值以生态合理最小水管理量（Qök）为基础，同时纳入水体天然支流的径流水位相关因素。为提升计算过程的可理解性与结果对比性，中间步骤的水位特异性数值已列于该矢量图层（shapefile）的属性表中，同时请参考配套文档。本次生态合理最小径流量的确定范围仅涵盖天然及受显著干扰的径流水体；从生态学视角而言，无需对人工水体设定最小需水要求。
