Estimation of Transverse Mixing Coefficient in Rivers and Experimental Flumes
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 1
Abstract
Rivers are the most important resource of drinking water and the chipset drainage for wastewater leaving agricultural lands, industrial regions and urban runoff. In later century, with increasing of civil population, many problems related to the pollution and quality of water resources have appeared. So study of mixing and translocation of materials in the rivers, are the important goals of water resource management programs. In mixing processes, specially, in the large and big rivers, longitudinal Dispersion and the transverse diffusion of pollution are the most parameters respectively. In this paper, in addition to introducing the measuring methods of transverse coefficient in rivers using collection of 19 hydraulic datasets, multiple suitable equations for estimation of this coefficient have been developed and accuracy of these equations compared to Fischer’s equation has been investigated. Furthermore, this coefficient is surveyed and evaluated.
