<b>Abstract :</b><p align=\"justify\"> <br /> A River can be definition as a channel system formed naturally, instead of flowing water. It also transporting sediment and erotion.. The erotion cause ferfile soil surface get peeled off (top soil). decreasing land production. The erotion level can be controlled. In order to prevent enviroment destruestion. So that it is nesaccazy to know how the erotion allowed. Predected from observing the condition an area that can endure production declined and damage of the soil surface <br /> <p align=\"justify\"> <br /> Besides sedimentation problems to estimate the dischange of the river can be done used a simple model. That represented through the regrcsion correlation between dischange (Q) with element geometry moist section. That is area (A) ,width (W), height (I)), ratio width to height (WID) and slope surface water (S) .As done in the reseach trying to use the simple model for Citanduy River in west Java, in four observing post location with 45 dischange datas used to design the model and tested the measured dischange in withing river at Pataruman. Concerning with the statisticed accuracy criteria. It showed that the model selected to be used to estimate the dischange. <br /> <p align=\"justify\"> <br /> In this reseach HEC6 is used to analyzed the rate change of bed river elevation and sediment transport. It\'s a part of Citanduy River area, then simulated and analyzed with one dimension model. Using cubic spline program for calculating the rate of sediment volume transporting in Citanduy River at Pataruman.
