In the present research Experimental Determination of Manning roughness coefficient for granular surfaces by simulating a natural channel of rectangular section is intended to experimentally determine the coefficient of Manning, through the design and construction of a physical model of a channel called ““channel morphological processes““, because it simulates a section of a river bed and you can also perform other experimental work with granular material as scour and erosion pillars, piers, barrages, etc. Viewing and hydraulic phenomena. Materail as samples taken from work Chicama downstream sector River Bridge Punta Moreno, selected granular material by sieving and washing of the samples was used. This channel was located in the laboratory of Fluid Mechanics and Hydraulics of the University Antenor Orrego, in order to undergraduate students can also perform the tests performed and improved. He anlizo theoretically roughness coefficients for channels with gravel base and rocky channels considering normal and another in extreme conditions due to the passage of water and observe the washing material. It has made several experimental tests considering the materials to calibrate equipment and reduce errors in the tests. Finally three trials were considered, of which has been considered three thicknesses of material 5, 7 and 9 cm, noting that as the water passes through the gravel this reduced the tight achieving measure different water heights as shown in the tables result.
