Leonardo da Vinci (1452-1519) stated, "I will treat of such a subject. But first of all, 1 shall make a few experiments and then demonstrate why bodies are forced to act in this matter. " Even with the current advancements of mathematical numerical models, certain complex three-dimensional flow phenomena must still rely on physical model studies. Mathematical models cannot provide adequate solutions if physical processes involved are not completely known. Physical models are particularly attractive to investigate phenomena-involved sediment movements because many three-dimensional sediment processes are still unclear at this stage. Theoretically, there are numerous factors governing movable bed processes and it is nearly impossible to design model studies to obey all the model criteria. Sometimes, appropriate lightweight materials are difficult or too costly to obtain. Often, distorted models are used due to the limitation of available space and the requirement for greater vertical flow depth to investigate vertical differences of various parameters. The turbulence level in the model may also b | | 出版日期 | Book 1990 | | 關(guān)鍵詞 | experiment; reproduction; transport; turbulence; hydrogeology | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-2081-1 | | isbn_softcover | 978-94-010-7434-6 | | isbn_ebook | 978-94-009-2081-1Series ISSN 1389-2185 | | issn_series | 1389-2185 | | copyright | Kluwer Academic Publishers 1990 |
