Short Outline
In recent decades, with more attention to sustainability, there is a greater understanding of the vital role of urban rivers. This paper offers an understanding to the challenges of urban rivers based on recent practices by means of comparative analysis.
The history of human settlements is intertwined with different aspects of
water. Among water resources, ‘flowing waters’ such as rivers, streams,
creeks, etc. have a prominent role as they are the lifeblood of most cities
in terms of providing transportation, security, energy, irrigation,
commerce, and recreation. By the late 19th century, developments of
terrestrial transportation modes diminished the magnetism of rivers and
growing industries led to the deterioration of rivers. Urban rivers
suffered from discharges of sewage, industrial waters and stormwater, and
careless exploitation of water supply. Rivers are among the most sensitive
of all ecosystems to climate change as well. After being neglected for
decades, since the second half of the 20th century, with more attention
given to sustainability of resources, an awareness has grown of the vital
role of urban rivers as a resource for humans and a lifeline for cities. As
a result of the problems associated with urban rivers cannot be isolated
from the water system; a new approach was developed for the last decades,
one that is integrative, taking the problem of rivers within the water
system. Besides growing consciousness about urban river and their urban
integrity, urban rivers gets attention as they are significative elements
of cities, within the global agenda as well. Aiming to create sustainable
cities, there is a concentration on the development of many transformation
projects including urban waters.
In this regard, the paper aims to better understand the challenges on urban
rivers in the meaning of its integration to urban water system. To be able
to clarify the challenges, the discussion extends into the old and emerging
paradigms. The discussion is supported by major practices on rivers and
comparative analysis on them conducted. Evaluating Porsuk River as a case,
Turkey in accordance with the contemporary context, provides a framework on
the dynamics of new approaches in Turkey as a final outcome.
