"Considerable progress has been made on the regional acidification analysis by intelligent systems on a microcomputer, acronymed RAISON-MICRO, particularly in the area of storage, manipulation and display of watershed data. The RAISON-MICRO system is designed to examine the relationships between terrain sensitivity indexes which assess susceptibility to acid deposition according to geologic and soil factors, and resultant aquatic chemistry. Interactive procedures making use of geographic indicators for region, watershed, and sampling site permit fast and concise data retrieval and data base editing. External computer systems including mainframes can be accessed for data transfer via menu driven protocols. Statistical analysis including frequency distributions and step-wise multiple regression analysis as well as mean, median, standard deviation and standard error can be produced on any of the data variables through a menu driven analysis package. The systam is also able to seed data for specified watersheds to a programmable function library"--Abstract. Includes abstract in English and French. gccst Acid rain gccst Software Fraser, A. S.
