Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional reservoir water quality model, CE-QUAL-R1, is currently being developed for use by U.S. Army Corps of Engineers District and Division Offices. Tests are needed which will ensure that model predictions are satisfactory. Although the literature contains much information concerning model evaluation, there is little agreement among authors concerning specific tests. Two general types of tests are proposed. The first group of tests are used to ensure that the coding of the model is correct, and the second group to ensure that the model predictions are suitable for the needs of the Corps. The latter tests include both qualitative and quantitative comparisons of model predictions with field-measured values. It is argued here that a thorough model evaluation must include comparisons of fluxes between variables, as well as comparisons of the mass or concentrations of variables.

Download or read book Evaluation of the Model CE QUAL R1 for Use by the Aquatic Plant Control Research Program written by Joseph H. Wlosinski and published by . This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Corps of Engineers One-Dimensional Reservoir Water Quality Model (CE-QUAL-R1) was evaluated for use in the Aquatic Plant Control Research Program (APCRP). Calibration of the thermal portion of the model for a period of one year and subsequent verification for a period of three years produced satisfactory results concerning the water budget and temperature predictions. Calibration of the water quality portion of the model also produced satisfactory results. Measured data were not considered satisfactory for model verification. It was concluded that CE-QUAL-R1 would be useful to the APCRP for predicting water quality variables after the addition of a macrophyte algorithm and after improvements are made concerning the interaction between the algorithms, time step, and solution scheme. All current model developments within the Environmental Water Quality Operational Studies Program should enhance model use for the APCRP. Other possible improvements which should be considered include the incorporation of: (a) output dealing with system function, (b) input via rainfall, and (c) effects of wind on sediments.
Download or read book Confirmation of the Water Quality Model CE QUAL R1 Using Data from Eau Galle Reservoir Wisconsin written by Joseph H. Wlosinski and published by . This book was released on 1985 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional model (CE-QUAL-R1) of water quality of reservoirs was evaluated using data collected on the Eau Galle Reservoir, in west-central Wisconsin. Data collected on the Eau Galle Reservoir, in west-central Wisconsin. Data collected in 1982 were used for confirmation. Graphical and statistical comparison were made for over 6.500 samples representing 21 variables. The statistical test used for comparing measured versus predicted values was the Reliability Index (RI). The average RI for each variable indicated that precision was always better than a half-order of magnitude, even for variables that ranged over more than three orders of magnitude. Graphs are presented for all variables, including profiles for the date with the poorest predictions (according to the RI). In addition, comparisons of measured and predicted flux values were satisfactory, helping to ensure that reasonable predictions were made for the correct reasons.

Available in PDF, EPUB and Kindle. Book excerpt: The use of models to assess water quality is becoming increasingly important worldwide. In order to be able to develop a good model, it is necessary to have a good quantitative and ecological description of physical, chemical and biological processes in ecosystems. Such descriptions may be called ``submodels''. This book presents the most important, but not all, submodels applied in water quality modelling. Each chapter deals with a specific physical process and covers its importance, the most applicable submodels (and how to select one), parameter values and their determination, and future research needs.The book will be an excellent reference source for environmental engineers, ecological modellers and all those interested in the modelling of water quality systems.

Book excerpt: This two-volume reference presents a series of review and research articles on advances in computing, marine physics, and remote sensing and addresses their importance to shallow sea modeling. Intended as a tribute to Dr. Norman Heaps, topics in the book reflect the range and diversity of his work, as well as his influence on international marine science. Topics discussed include numerical techniques, flow in homogenous sea regions, stratified flows, lake regimes, validation of numerical models, remote sensing as a method to collect oceanographic data at the sea surface, and bottom boundary modeling. Marine scientists actively involved in mathematical modeling and scientists who are interested in using models as tools to gain more insight and understanding of the processes they are observing will find this text useful.
