Kuala Samboja is a port situated in East Kalimantan, precisely in Kutai Kartanegara Regency and is located between the Samarinda Port and Balikpapan Port so that this port is expected to support the two ports. A port certainly needs to design water resources aspects such as seaside facilities, reclamation protection or revetment, and an eco-hydraulic drainage system so that the port can operate properly. The design of seaside facilities is carried out to ensure the ship can moor safely against waves and tides at the pier. Reclamation protection or revetment should also be designed to protect reclaimed land from high waves and runup on the coast. In addition, the drainage must be planned so that the land side of the port is not flooded by rainwater that falls there. The seaside facilities designed are at the pier, shipping channel, harbor pool, turn, and dock elevation. Natural conditions that affect these things are sea waves, currents, tides, and bathymetry. The dimensions of the ship determine the design of the shipping channel. The revetment’s top elevation consists of the height of the breaking waves on the beach, the wave runup and the tidal ridge in advance. The design of the ecohydraulic drainage system consists of network design and conventional drainage dimensions, water storage, water supply, and infiltration wells to absorb excess water in the nearest green land. The drainage design uses daily rainfall data obtained from the BMKG website. It is found that the rainfall for the 5 year return-period. The synthetic unit hydrograph calculation is also performed to get the peak discharge hydrograph. The conventional drainage is made of concrete. There is also a sub-reservoir at the general cargo terminal. Finally, excess water is infused through 65 units of infiltration wells.
