Abstract

River flow velocity is the movement of elements of water mass through the cross section of the river unity of time. Naturally; the speed (fluid movement) in the estuary area is controlled by two main factors namely river flow and tides. The measurement and determination of points (according to the depth and width of the Ranoyapo river mouth) must be such that the steady; non-turbulent or homogeneous flow requirements are met. The availability of data and the profile of the flow velocity variable can be used as a reference for the analysis of the flow velocity distribution model and changes along the Ranoyapo Amurang estuary at high tide. The velocity v0.6h model at high tide shows that the velocity function is exponentially negative; where the velocity distribution v0.6h at high tide at a position of 600 meters towards the coastline; has an exponential model function applicable to 82 meters £ x £.. 600 meters. The velocity functions v0 and v0;6h at low tide produce the same model shape; the exponential (negative) function; in the condition of v0 when low tide is above the flow velocity at high tide; thus v0.6h at low tide has a lower gradient than with the tide. Physically; this is due to the higher density of sea water; compared to the density of river water so that the profile of the boundary plane of the two water masses has a gradient decreasing upstream.
