HCM – 20-2019

Waters: Ho Chi Minh City, Dong Nai Province.

Fairway: Dong Nai fairway.

VMS-South would like to inform that:

Within surveyed of the survey of Dong Nai fairway, is limited and guided by AtoN system, the smallest depth in meters from the water level “0” Charts are as follows:

  1. Paragraph 1: continuation of fairway Saigon – Vung Tau in Nha starting nose red light to the junction canal pipes length 9.5 km, width 150m stream bottom, smallest depth reached 8 , 5m.
  2. Section 2: from the junction canal downstream pipes to Dong Nai (Dong Nai Bridge 150m) length 26,2km, 150m bottom width flow as follows:

- Shallow right stream extending from upstream buoy number “15” + 100m to upstream buoy number “15” + 160m, length of about 60m, encroaching stream farthest 76m, the depth of the smallest in the middle of the heart stream reach 8,2m, 7,8m depth the smallest gain.

- Strip land is located on the left-stream extending from upstream buoy number “15” + 340m to upstream buoy number “15” + 400m, length of about 60m, encroaching stream farthest 20m, minimum depth of 7, 9m.

- Appeared shallow 8.4m; 4.8m; 6.5 m at the position of the coordinates:

- Shallow stream to the right target extends from posting Buoy “23” to the target upstream of beacon “23” + 330m, 330m in length, 12m farthest stream encroachment, the smallest depth reaches 7.7 m located marginal stream.

- Shallow right stream extending from the downstream float Buoy “27” – 420M to float Buoy “27”, length of about 420M, encroaching stream farthest 100m, depth of the smallest in the middle of the heart flows reached 8, 1m, 7,0m depth the smallest gain is marginal stream.

- The float downstream from Buoy “28” – 620m upstream to float Buoy “28” + 290m, 910m in length, the smallest depth in the middle of the stream reach 6,9m heart, the smallest depth reaches 6, 5m.

- The float downstream from Buoy “39” – 800m to float Buoy “41”, approximately 4.6 km in length, the smallest depth in the middle of the stream reach 4,4m heart, reached a depth of 3.0 m is the smallest left marginal stream, flows from the left border of about 11,0m.

- Clips from buoy number “41” to the lower Dong Nai Bridge (Bridge Dong Nai 150m), about 3,7km length as follows:

+ Survival reefs located on the left-stream, between pairs of buoys BHHH symbol “E1″, “E2″, reefs stream encroachment farthest 48m, smallest depth of reef reaching 1.2m at the encroaching stream location coordinates are as follows:

Depth (m) Contacts VN2000 WGS-84 system
Latitude (j) Longitude (l) Latitude (j) Longitude (l)
1.2 10052’12,1” N 106050’37,1”E 10052’08,4”N 106050’43,6”E

+ In addition to the reef at a depth above this stream segment reached 4,1m.

In addition to the shallow, shallow reef bands above paragraph depth reaches 8.5 m or more streams.
