AB  - As maritime state, most of Indonesian reside in coastal areas or estuaries, leading sanitation and water
supply a major concern of the people. The use of groundwater with considerably limited amount is more limited
due to seawater intrusions. On the other side, surplus of freshwater from upstream is very abundant near the
estuaries. However, morphological condition of river downstream or in estuaries with huge dimension and
depth causes expensive cost in order to utilize freshwater in estuaries. One of the solutions to utilize water
downstream or near estuaries as raw water for clean water is to build free intakes around river estuaries.
However, as the utilizing proceeding it is found a problem that intake capacity is far below their design capacity.
The research is an experimental research conducted in the laboratory which aimed to investigate the relationship
of flow velocity distribution on no free intake and with free intake condition and its influence to the capacity
of free intake structures. The result shows that either on no free intake and with free intake condition minimum
velocity occurs around channel bed and increasing upright and decreasing again when approaching surface
of the channel. The positioning of intake pipe is highly influencing intake capacity. Maximum condition is
achieved when intake pipe is positioned on channel bed and near channel surface while minimum condition is
achieved when pipe is around middle part of the channel.
