Veronese, A. (author)The note summarizes the study and the results of two series of experiments, carried out in the laboratory, on the erosion of the mobile bottom downstream of a drain (model). Confirming the degree of reliability of the method followed and the final results, the formulas deduced are applied to the underlying erosions found in two cases on...report 1937

Gorio, O. (author)Overview of the studies and works in the Po river (Italy) in the years 1919 to 1941. The object of the work is the arrangement of the river Po with "free flowing water"system for the navigation profit and for the hydraulic protection, projectation and execution of the works. Moreover there is described an economic an special system adopted for...report 1953

Frijlink, H.C. (author)Extensive study or the rivers Niger and Benué in order to describe the hydraulics and morphology with the aim to improve inland navigation in Nigeria. Part I gives a summary of the original NEDECO studies and their results as contained in the Report, without summarising the information obtained from other sources. This is followed by a...report 1959

Anonymus, A. (author)If we plot the discharges of natural water-courses measured under all manner of circumstances against the water levels measured at the same time, the points obtained win give us what is called the stage-discharge relation curve. But it should be noted that the relation win only be a true one ifthere is no backwater effect (due, for exampIe, to a...report 1969

Berdenis van Berlekom, H.A. (author)It is the task and target of River Engineering as a profession to provide all the tools for arriving at an optimum utilization of the potential resources, optimum in the sense of promoting the beneficial characteristics of the river and eliminating or at least checking the adverse qualities. To strive for this aim, there must be a scientific...report 1969

De Vriend, H.J. (author)The axisymmetrical, viscous flow in curved channels is considered in the case where the hydraulic radius of the cross-section is small with respect to the average radius of curvature of the bend. First Ananyan's theory on this subject is reconsidered, using a regular perturbation method. The results are applied to a specific channel with a...report 1972

Hooke, R.L.B. (author)A one-meter wide, meandering flume with movable sand bed was utilized in these experiments. Uniform flow was established at discharges of 20, 35, and 50 l/sec. Velocities near the bed, the distribution of sediment in transport, bed geometry, and strength of secondary flow were determined at each discharge . Bed shear stress was assumed to be...report 1974

Van der Veen, K. (author), Van Bennekom, A.J. (author), Tijssen, S.B. (author)Observations were made of temperature, salinity, currents and meteorology in the ocean off the northern coast of South America, during autumn 1970 and spring 1971. The observed salinity distributions in the surface layer reflect the seasonal variation in the trade winds. Besides, very strong vertical current shear waS found over the layer...report 1976
