Abstract
Debates on irrigation have recently integrated the concept of sustainable water
use, involving qualitative and quantitative conceptualizations of flows of
resources. The nature of unstable water availability during seasons and over years is
a key issue. A storage facility is usually desirable. In the process of enlarging
control through such facilities, water patterns in basins, in terms of flows, storage
and use have changed. This paper discusses historical patterns of water flows in
the Río Dulce basin in Argentina, in which the irrigation area known as the
Proyecto Río Dulce has an immense influence on the catchment water balance.
Keywords: irrigation, river basin, water flows, catchment, Argentina.
1 Introduction
An important issue in water management is the nature of unstable water
availability during seasons and over the years. Many rivers have an irregular
flow pattern, with large fluctuations in and over seasons and very low flows in
the dry season. In such a setting it is difficult to match water availability with
actual water requirements. In many river basins, exploitation of the river through
damming, channel manipulation, power generation and irrigation has become
very intensive. Latin America is not an exception. The basin of Río de la Plata,
fifth largest in the world with its area of 3.1 million km2 counts a large number
of dams, used for flood control, irrigation and industrial supply too. Petts [1]
sketches the relationship between water, engineering and landscape as a threephase
development:
