Abstract
Since the beginning of the 19th century the monitoring of climate phenomena
has made considerable progress, first through the use of analogue media and,
more recently, through computer systems and remote communications, including
meteorological radar and the analysis of satellite information.
There has been notable development of Geographical Information Systems
(GIS) for Hydrology and Water Resources in the past twenty years, with the
introduction of geoprocessing for spatial analysis.
In this communication we describe the development of tools for systematizing
the use of a GIS in different situations in the water domain: more precisely, in
the definition of flood plains, in the hydrologic and hydraulic evaluation of the
use of the water domain and in the quantification of sediment transport in a water
course.
Keywords: water basin, floods, GIS, hydraulics, hydrology.
1 Introduction
1.1 Generalities
The analysis of extreme flow conditions and the consequences of such
phenomena open up a wide array of possibilities for study. Land use planning,
environmental components, like regularizing and using water resources, and
social questions related to civil protection, are among the key issues intrinsically
related to extreme flow conditions.
Keywords
water basin, floods, GIS, hydraulics, hydrology.
