Objectives

The objective of the project is to analyze the data of precipitation of the countries involved and produce a statistical analysis for the various subregions allowing to answer the following questions:


How often droughts are observed?
What is the probability that the current drought will end in X months?
How long will the drought last for which we must prepare?
What is the frequency of maximum drought intensity observed?
The answers to these questions serve as as an input to the planning and to form the basis of a decision-making system on the issue of drought.

Activities Organization

This activity is developed in conjunction with the Institute for Water Resources (IWR) of the Army Corps of Engineers-USA with whom CAZALAC signed an agreement during 2007. It involves a professional from the IWR and a Yale professor, Dr.. James Wallis, who was part of the expert group that developed the Atlas of US Drought: (Http://www.iwr.usace.army.mil/iwr/atlas/Atlasintro.htm)

During 25th  and 26th of March 2008 a workshop was held in Santiago, bringing together professionals from Argentina, Peru and Chile. In the workshop, Dr. James Wallis (one of the pioneers in using the methodology of the Regional Frequency Analysis, which was prepared USA Drought Atlas), introduced the participants to the methodology used in the development of a Drought Atlas, and the main difficulties involved as well as proposing solutions for pilot cases brought by each of the countries. The project was launched in a pilot area of Argentina, Peru and Chile.
