| 520 | |a"This document describes the CHyF logical model, a profile of the HY_Features conceptual model and also an implementation of it. CHyF is intended to meet the needs of hydrologists and environmental professionals concerned with hydrologic assessments or the health of watersheds and river systems. CHyF pertains to the description and behaviour of hydrologic features found on the surface of the earth. It is relevant to such questions as: where does surface water exist, how much of it is there, how does it change over time, what is upstream or downstream of what, how are land features connected to water features, and how can other types of data be related to water features. Groundwater and atmospheric phenomena must be taken into account with surface water features for many applications. However, they are out of scope for this document. Nevertheless, recent work demonstrating such links is described elsewhere"--Scope, page 3. |
