  • Garolim Bay is typically a semi-enclosed bay without a significant supply of freshwater and sediments from surrounding drainage area. The bay have a variety of subenvironments including deep tidal channels, tidal flats, sand dunes, islands, and inlet. Because environmental quality of bay strongly depends on the exchange of water over benthic subenvironments, it is necessary to analyze quantitatively exchange of water between sea and bay. Hydro-hypsography is the relative distribution of water-surface areas at different depths. The hydro-hypsographic curve in Garolim bay shows that the tidal flats occupy about 77 % of the bay surface. Hydraulic turn-over time (HTT) is 1.32 tidal cycles which indicate well-flushed bay. Hydro-hypsometric techniques will be useful for assessments of health of bays.
