5203 |a"The recognition that groundwater supplies are susceptible to contamination by pesticides has led to the development of a number of pesticide transport and transformation models capable of assessing the potential for the contamination of groundwater. The computer codes are categorized into two main groups, screening models or mathematical models, based on the approach taken in the assessment. Mathematical models are further sub-divided into educational, management and research models, according to the level of complexity incorporated in the models. A literature review identified 15 existing pesticide models. These models are briefly discussed, under their appropriate classification. Selection criteria and typical applications for the different model classifications are discussed and typical output from two of the models is presented"--Abstract.
