Abstract

The issues related to the assessment of the hydro morphological status of urban rivers in order to identify the revitalisation actions possible to be carried out, has been acquiring significant importance in recent years. The revitalisation of urban rivers and the waterfront urban space must be preceded by an assessment and determination of the direction of revitalisation measures necessary to be implemented. Most of the methods used worldwide to assess the hydro morphological condition of the river do not include the element of planning revitalization activities. Meanwhile, there is a close relationship between the morphological conditions of the river and its corridor, and the range of necessary and feasible activities aimed at recreating some of the natural features of the river, with the simultaneous increase in the possibility of using the adjacent area as a safe public space. The existing methods used to identify places where revitalisation works are possible, omit many morphological elements of the rivers under analysis. This makes impossible to monitor their morphological status later and assess the effectiveness of the implemented works. The paper presents the results of the Unified Stream Assessment (USA) method of the urban river Kłodnica, located in Upper Silesia, which is the area with the largest degree of urbanisation and industrialisation in Poland. The conducted assessment allowed to determine possible revitalization activities, indicated significant limitations as well as the need to modify the USA method. Results of the study revealed that proposed revitalisation actions based on the USA assessment should take into account the nature of the whole watershed and not just river corridor. The modification of USA method results proper development of urban river assessment and revitalisation process.

统一流评估方法在确定重整城市河流复兴方向上的应用

摘要

近年来，与确定城市河流水文形态状况有关的问题，以识别可能采取的振兴行动，已变得越来越重要。在振兴城市河流和海滨城市空间之前，必须先评估和确定必须采取的振兴措施的方向。世界范围内用于评估河流水文形态状况的大多数方法都不包括计划振兴活动的要素。同时，河流及其走廊的形态条件与旨在重现河流某些自然特征的必要和可行活动的范围之间有着密切的关系，同时增加了将相邻区域用作安全公共空间的可能性。用于识别可能进行复兴的地点的现有方法忽略了所分析河流的许多形态要素。这使得以后无法监视其形态状态并评估已实施作品的有效性是不可能的。本文介绍了位于Upper Silesia的城市河流Kłodnica的统一河流评估（美国）方法的结果，该地区是波兰城市化和工业化程度最高的地区。进行的评估可以确定可能的振兴活动，表明存在重大局限性以及需要修改USA方法。研究结果表明，基于美国评估建议的振兴行动应考虑整个流域的性质，而不仅仅是河流走廊。美国方法的修改导致城市河流评估和振兴过程的适当发展。
