Popis: This paper presents the application of sluice gates to control the excess runoff in the wide and very mild channel in an industrial area which is located in the Cikande, Banten, Indonesia. St. Venant equation is used and solved by 1-D model HEC-RAS. The result shows that the main channel can be utilized as a long storage or long reservoir if it is combined with sluice gates. Various scenarios of gates opening and closing operation have been conducted in order to determine the most effective gates operation. Two options of gate operations have been analyzed. The first option is the automatic option in which the gates are able to open and close automatically at a certain water level in the main channel. The second is manual option where the gates constantly open at a certain height. The results show that the main channel successfully reduced the 10 years of flood discharge from 37.45 to 17.37 m3/s for the automatic gates and from 37.45 to 17.38 m3/s for the constant opening. Although both options give the same result for controlling the flood, there are several differences between the options, especially the capability of both the systems to provide raw water for the industrial purposes. In conclusion, the automatic operation is the most effective operation, despite the fact that it is more expensive and harder to implement than the manual operation.
