The European Water Framework Directive requires the development of new and accurate methodologies, addressing the assessment of the physico-chemical status of transitional and coastal waters; these are considered by the Directive as the supporting elements for the final evaluation of the Ecological Quality Status. This contribution develops new approaches in the determination of the physico-chemical status, solving some problems detected in previous contributions, i.e.: (a) fitting the classification of water bodies and typologies, by means of the stretching of the typologies, according to the natural salinity gradient of types; (b) defining reference conditions, based upon the new approach to typologies, (c) proposing accurate multivariate methodologies, in determining the physico-chemical status of the transitional and coastal waters, based upon the defined typologies and references; and (d) discussion of the results obtained by reference to methodological aspects and water quality evolution in the Basque Country, Spain (as a case-study), during the last decade.
《欧洲水框架指令》要求开发新的精确方法，以评估过渡水域和沿海水域的物理化学状况；该指令将这些视为生态质量状况最终评估的支撑要素。本论文在确定物理化学状况方面开发了新方法，解决了先前研究中发现的一些问题，即：(a) 根据类型的自然盐度梯度，通过类型的扩展来拟合水体分类和类型学；(b) 基于新的类型学方法定义参考条件；(c) 基于已定义的类型学和参考条件，提出精确的多变量方法来确定过渡水域和沿海水域的物理化学状况；以及(d) 参考西班牙巴斯克地区（作为案例研究）过去十年的方法学方面和水质演变情况，对所得结果进行讨论。
