Test sections in laboratory studies should be fully developed and uniform if they are to be generalized. The objective of this study is to develop a model for predicting the uniform flow development length (Lunif) in a rough laboratory flume as a function of hydraulic parameters and bed particle roughness height (ks). Using an ADV time-averaged point velocity was measured in developing and fully developed turbulent subcritical rough open-channel flows. A series of laboratory tests were carried out in a 6.1-m-long and 0.46-m-wide rectangular channel. Tests were conducted with fine gravel (d50 = 5.8 mm, ks = 3.1d90 = 0.026 m), medium gravel (d50 = 14 mm, ks = 0.068 m), and with fine /medium gravel (d50 = 11 mm, ks = 0.04 m). For each test, longitudinal point velocity measurements were made along the center of the channel at five elevations, and at thirteen longitudinal stations. The study concluded that for flow to be uniform, the flow depth and mean cross-sectional velocity must be constant. In addition, root mean square of the fluctuating component of the velocity, RMS(u'), which is the measure of the turbulence intensity, should be uniform in order for a flow to consider uniform. Thus, RMS(u') is one of the indicative measures for determining the location where the developing flow is fully developed and uniform. The results showed that increasing the bed roughness height decreases the uniform flow development length. Using the dimensional and statistical analyses Lunif was estimated as a linear function of Reynold's particle number and Froude number.

This research was conducted in the urban area of the municipality of Crato-CE in the Cariri. The study anger dealing with the application of a hydraulic model for runoff and free channels in a channel that winds masonry part of the urbanized area of the city center and over the years has been occurring flood events due to variable rainfall in the city. The work done included field visits possession of equipment for conducting surveys, measurements of flow, collecting images and measurement field. The information obtained from this study will be a bibliographic database to contribute to the advancement of research and provision of data for better planning and management of water resources site. / Esta pesquisa foi desenvolvida na zona urbana do municÃpio de Crato-CE na regiÃo do Cariri. O estudo tratou da aplicaÃÃo de um modelo hidrÃulico para escoamento em canais livres em um canal de concreto que percorre parte da Ãrea urbanizada do centro da cidade e que ao longo dos anos vem ocorrendo eventos de inundaÃÃo por conta das variÃveis precipitaÃÃes no municÃpio. O trabalho elaborado contou com visitas em campo de posse de equipamentos para realizaÃÃo de levantamentos topogrÃficos, aferiÃÃes de vazÃes, coleta de imagens e mensuraÃÃo de campo. As informaÃÃes obtidas nessa pesquisa servirÃo de base bibliogrÃfica para contribuir no avanÃo de pesquisas e fornecimento de dados para um melhor planejamento e gerenciamento dos recursos hÃdricos local.
