The sampling site was placed on the lower shore around the northwestern corner of the sandflat, 260-280 m seaward of the upper shoreline and 30-50 m landward of the MLWS (Stn A in Fig.
To obtain a data set on the temporal variation in water velocity in relation to the water level close above the substrate surface through the reproductive season of Nihonotrypaea harmandi on the Tomioka sandflat, measurement was made using a 2-dimensional electromagnetic current meter (Compact-EM, JEF Advantech) and an underwater pressure-type wave meter (HJ-401, IO Technic), respectively, from May 27, 2010 to May 10, 2011, at a lower shore station, 50 m landward from the MLWS on the northwestern part of the sandflat (Stn B in Fig.
starting 1.5 h before MLWS and ending at high tide (7.5 h later).
Individuals were found up to 130 cm above MLWS (in the mid-high intertidal), but only at low densities of =10/[m.sup.2].
However she said MLWS
availed funding for minimal land servicing at Masunga, Matshelagabedi, Matsiloje, Shashe Bridge, and Tati Siding villages during 2016/17 financial year adding that more projects would be considered in future depending on funds availability.
The deepening covers an approximately 29,000 m large area with current water depths between approximately +2 and -6 meters MLWS
. The deepening be made to level -9.3 meters MLWS

Only a part of the sandy flat, which extends 4 km onshore to offshore, is exposed at mean low water spring (MLWS), with a total tidal amplitude of 2.0 m.
Banzu is a tidal flat, located at the Obitsu River estuary on the east coast of Tokyo Bay, consisting of the Obitsu River mouth, dredged channels and sandy flats, with a length of 12 km and offshore width of 1.0-1.5 km at MLWS. The second site, Kisarazu, is adjacent to the river mouth, which flows into Tokyo Bay in southern Banzu.
Indicator collectors were attached to ropes at 5 m, 10 m and 15 m beneath the water surface at MLWS
and installed in the Bally Hork Bay site in 1981 (Fig.
