T/ACEF 121-2023 Specification for the construction of numerical model of lake and reservoir water environment

Scope

Scope: This document specifies the technical requirements for selecting numerical models, collecting data, constructing models, calibrating and validating models, conducting simulations, and analyzing the rationality of results when assessing, analyzing, and forecasting water quality in lakes and reservoirs. This document is applicable to numerical simulations of water quality evolution processes in large reservoirs (including large hydropower projects and large water conservancy hub projects) and deep-water lakes. This document is applicable to routine numerical analyses of water quality in lakes and reservoirs, emergency analyses of water quality incidents, and special studies on water quality. Medium- and small-sized reservoirs and shallow lakes may refer to this document for use. Main technical contents: 4. Basic process of mathematical simulation of lake and reservoir water environments 5. Basic data requirements for models 6. Preliminary analysis of hydrodynamics and water quality conditions in lake and reservoir water bodies 7. Construction of numerical models for lake and reservoir water environments 8. Determination, calibration, and validation of model parameters 9. Mathematical simulation of lake and reservoir water environments and analysis of the rationality of results Appendix A: Basic equations and solutions of commonly used mathematical models Appendix B: General description of the transformation process of common pollutants Appendix C: Evaluation of the nutrient status of lakes (reservoirs)
