INTEGRATED PLANNING OF RURAL WATER SUPPLY AND SANITATION1

ABSTRACT: Development schemes to improve the health of the rural populace through prevention of the transmission of communicable diseases should be considered in the context of some kind of “Sanitation Package” to ensure effectiveness. The general practice of concentrating resources on limited objectives, like water quality improvement, is shown to be less effective than allocating the same resources to multi-objectives defined in the Sanitation package. Systems Dynamic Modeling based on the DYNAMO II language, is presented as a capable tool for sanitation systems planning.     

Optimization of ambient Air Quality Monitoring Networks

A method has been developed to obtain a joint solution to the problem of optimum number and configuration of ambient air quality monitors, on the principles of spatial correlation analysis and the minimum spanning tree. The interest in this case is to represent the patterns of regional air quality, at a minimum of an overlap of information. This methodology is extended to account for the uncertainties in air quality simulations and also to incorporate the probabilities of occurrence. As an illustration to these methodologies, an example of Taipei City, Taiwan has been considered.
