Spatio-temporal scaling of channels in braided streams
نویسندگان
چکیده
The spatio-temporal scaling relationship for individual channels in braided streams is shown to be identical to the spatiotemporal scaling associated with constant Froude number, e.g. FrZ1. A means to derive this relationship is developed from a new theory of sediment transport. The mechanism by which the FrZ1 condition apparently governs the scaling seems to derive from the sensitivity of sediment transport to flow fluctuations when FrZ1. The condition FrZ1 is also given a theoretical basis using arguments from surface roughness. q 2005 Elsevier B.V. All rights reserved.

Assessment of Neonate's Congenital Hypothyroidism Pattern Using Poisson Spatio-temporal Model in Disease Mapping under the Bayesian Paradigm during 2011-18 in Guilan, Iran
Background: Congenital Hypothyroidism (CH) is one of the reasons for mental retardation and defective growth in neonates. It can be treated if it is diagnosed early. The congenital hypothyroidism can be diagnosed using newborn screening in the first days after birth. Disease mapping helps to identify high-risk areas of the disease. This study aimed to evaluate the pattern of CH using the Poisso...
متن کاملImproving Low Bit-Rate Video Coding using Spatio-Temporal Down-Scaling
Good quality video coding for low bit-rate applications is important for transmission over narrow-bandwidth channels and for storage with limited memory capacity. In this work, we develop a previous analysis for image compression at low bit-rates to adapt it to video signals. Improving compression using down-scaling in the spatial and temporal dimensions is examined. We show, both theoretically...

Objectives: The purpose of this study was to compare spatio-temporal gait parameters between elderly and young male subjects. Methods & Materials: 57 able-bodied elderly (72±5.5 years) and 57 healthy young (25±8.5 years) subjects participated in this study. A four segment model consist of trunk, hip, shank, and foot with 10 reflective markers were used to define lower limbs. Kinematic data c...
متن کاملEvaluation of Tests for Separability and Symmetry of Spatio-temporal Covariance Function
In recent years, some investigations have been carried out to examine the assumptions like stationarity, symmetry and separability of spatio-temporal covariance function which would considerably simplify fitting a valid covariance model to the data by parametric and nonparametric methods. In this article, assuming a Gaussian random field, we consider the likelihood ratio separability test, a va...

Rivers have different patterns of plan forms. Straight and meandering rivers have single channel but braided, anabranching and anastomosing rivers have multi channels. Gamasiab River in Kermanshah province has different plan forms of channels. In this study, historical method is used and is investigated different plan form and river's changes with using of aerial photography of 1955, 1969, 2003...
