Interpretive Summary: The first of a two part final report by the Am. Soc. Civil Engineers, Task Committee on applications of Artificial Neural Networks in Hydrology covers the fundamentals needed to carry out applications. This tool from artificial intelligence has been highly touted, but its applicability to hydrology not determined. The task committee was charged with making such an assessment. The results are described in Part II. This research will benefit water resources engineers and planners who will use it in analyzing the effects of improved practices on the response of a watershed to rainfall events.

Technical Abstract: In this two-part series, the writers investigate the role of artificial neural networks (ANNs) in hydrology. ANNs are gaining popularity, as is evidenced by the increasing number of papers on this topic appearing in hydrology journals, especially over the last decade. In terms of hydrologic applications, this modeling tool is still in its nascent stages. .The practicing hydrologic community is just becoming aware of the potentia of ANNs as an alternative modeling tool. This paper is intended to serve as an introduction to ANNs for hydrologists. Apart from descriptions of various aspects of ANNs and some guidelines on their usage, this paper offers a brief comparison of the nature of ANNs and other modeling philosophies in hydrology. A discussion on the strengths and limitations of ANNs brings out the similarities they have with other modeling approaches, such as the physical model.
