Abstract
Soil and water conservation is a priority in the watersheds of arid and semi-arid regions for the proper planning and integrated management of water resources. The objective of this work is prioritizing 91 watersheds in 14 regions of Peru with different geographical, hydrological and geological conditions, through the integration of Geographic Information Systems (GIS), Principal Component Analysis (PCA) and the Weighted Sum Approach (WSA). In addition, homogeneous regions were identified with hierarchical Cluster Analysis in R and Ward's method. The result showed the existence of 19.49 % of total area in high and very high priority category in two regions. The results of the Cluster Analysis showed that 35 % of the watersheds have homogeneous zones within the geometric and shape factor, while 65 % within the drainage and relief factor. In general, GIS, PCA and SWA methods are an efficient tool, which allows decision-making authorities for better planning and conservation of natural resources in hydrographic watersheds.
期刊介绍：
Published by the Mexican Institute of Water Technology, Water Technology and Sciences (Tecnología y ciencias del agua) is a highly specialized journal which reflects two important characteristics:
The interdisciplinary nature of its articles and notes.
The international scope of its authors, editors, reviewers, and readers.
It constitutes the continuity of the journal Irrigación en México (Irrigation in Mexico) (1930-1946); Ingeniería hidráulica en México (Hydraulic Engineering in Mexico) (1947-1971); Recursos hidráulicos (Hydraulic Resources) (1972-1978), and Ingeniería hidráulica en México, second period (1985-2009).
The journal is aimed at researchers, academics, and professionals who are interested in finding solutions to problems related to the water.
The journal’s contents are interdisciplinary and contain previously unpublished articles and notes that offer original scientific and technological contribution that are developed in the fields of knowledge related to the following disciplines:
Water and energy.
Water quality.
Hydro-agricultural sciences.
Political and social science.
Water management.
Hydrology.
Hydraulics.
