1. INTRODUCTION
The coastal area of the Lower Mekong Delta (LMD) influenced by waves, tidal currents,
changing sediment loads from the Mekong and Saigon-Dong Nai river system, and storm
surges from the East and West Sea. In addition, human activity has an impact on erosion
and deposition processes through dyke construction and drainage, agriculture,
aquaculture, and fishery exploitation along the coastal areas. In recent years, the impact
of upstream dams, especially on the Mekong main river, has reduced sediment feeding
into the LMD and its estuary. All of these impacts have caused shore erosion along
approximately two thirds of the total coastline length, and a land loss rate of about 500
ha/year in the past ten years. In the future, climate change and sea level rise will make
this situation worse. Figure 1.1 shows the LMD and seasonal wind patterns affecting the
seasonal transport of sediment along the coastal zone; Figure 1.2 shows the estimation of
erosion and deposition rates along the LMD coastal zone.
The subject of this project is the coastal zone of the Vam-Lang, Kieng-Phuoc, Tan-Dien,
and Tan-Thanh communes of the Go Cong district (Tien Giang province), located at the
coordinates of 106o40’50’’ ÷ 106o47’40’’ Easting and 10°15'35” ÷ 10°25'45 Northing. Research area is contiguous to the Soai Rap River in the North, to the Cua Tieu River in
the South, to the East Sea in the East and to the Go Cong Eastern Dyke System.
2. OBJECTIVES
The goal of the project is to model the coastal erosion situation of Go Cong with Telemac-
Mascaret Modeling Suite to propose the coastal protection measures.
This report presents the results of calibration and validation of flow and wave numerical
models over the regional and local zones for further simulation in the LMDCZ.
3. METHODOLOGY
A desirable approach for this project is integration from general to specific. Firstly, the
whole LMDCZ should be considered in the context of South China Sea with its
hydrodynamic characteristics. Secondly, the impact of human activities should be
estimated, especially the reduction of sediment to the LMD and coastal area due to
upstream Mekong dams. In addition, sea level rise from climate change should be
accounted.
The numerical approaches will be used for this work-package with consideration of
experimental works in other work-package of the project. The well-known numerical
models such as TELEMAC-2D, TOMAWAC and SISYPHE will be used to compute
waves, currents, and sediment plumes in the LMDCZ.

The LMDCZ project will use the whole South China Sea model solutions for tidal and
wave fields in the East and West Seas. The LMDCZ project will use the results obtained
from the large-scale study as initial and boundary data for the simulations with very fine-
scale resolution of tides, waves and geo-morphological changes.
Then, the numerical simulations of the whole LMDCZ will provide boundary conditions for
simulations of regional areas, which will in turn provide initial and boundary conditions for
the study areas, that is Go Cong (largely impacted by the Mekong estuary and the East
sea flow-wave regimes).
Modeled shore protection measures for Go Cong should be considered both as “hard” and “soft”. The appropriate protection measures need to be assessed based on numerical models with consideration of physical models, focusing on their possible impact in the
long term, under changing conditions for sediment sources and climate.
In order to calibrate the model for flows and sediments, 2 additional measurement
campaigns, each lasting 15 days, in the estuaries and in coastal zones along the lower
Mekong Delta. The two 15-day measurement campaigns for each site is carried out in
October 2016 and in February 2017.
There are 6“stations”planned for each campaign, including: 2 stations in Mekong (at My Thuan) and Bassac (at Can Tho) rivers (coincided with
National Hydrology Stations) for measuring discharges (Q) and suspended sediment
concentration (SSC) by ADCP.
2 fixed stations at Go Cong and U-Minh;
2 “mobile” ships along the East and West seas Measured fields for the 4 latter “stations” will be:
Water level (hourly at the 2 fixed stations) Vertical distribution of velocity Vertical distribution of salinity (5 points for each vertical line) Vertical distribution of sediments (5 points for each vertical line) Waves (height, period and direction)
Numerical models have reached a level of accuracy and detail over the past 25 years that
most of the dominant processes in the coastal environment can be quantified. However,
the numerical models are tools only for the coastal engineers and planners.
I ideal, the study is should be divided into 2 parts: a) baseline study and b) measures’ assessment. Baseline studies of ocean and coastal conditions leading to:
Baseline description of wind, waves and tides in the area
Coastal classification
Description of littoral drift conditions
Equilibrium orientation of shorelines

Description of variability in above conditions
Regional and extended zones modeling
Sufficiently long recording of time series of tides and waves is normally not available at a
project site as basis for establishment of design conditions, whereas wind recordings and
weather maps are normally available from local meteorological stations and international
organizations (NOAA, NCEP,.etc.). Such wind and air pressure data are very suitable as
input data for spectral wind wave models and 2D or 3D hydrodynamic flow models. The
combination of advanced numerical wave and hydrodynamic models and powerful
computers thus makes it possible to run long time series, i.e. decades of years, of
hydrodynamic and wind wave simulations thereby providing basis for establishment of a
baseline description of the following offshore conditions:
Winds
Waves
Currents and flushing conditions
Tides and storm surges
Possible shorter recording time series of waves, tides and currents are suitable for
calibration of the numerical models. The established time series of regional marine
parameters are thereafter suitable for statistical description of normal conditions as well
as of design conditions. Furthermore, the established regional models can provide
boundary conditions for local wave, hydrodynamic and sediment transport models
Local area modeling
The study of the conditions in the local project area will normally require the
establishment of local models. The new generation of such models are Flexible Mesh
Models, in which the local model resolution can be adjusted as required. This technique
provides the possibility of modeling large areas in one single model without shifting to
several layers of finer grid models
4. MODEL SETUP, DATA USED, CALIBRATION AND VALIDATION
4.1. MODEL SETUP
Figures 3.1, 3.2, 3.3 depict the research scope of the models with different scales and
levels of details. The Regional computational model (RCM) was established for the whole
South China Sea with the aim of deep-water waves modeling to get wave and current
boundary data for more detailed models. The main boundary for the RCM model itself are
located at Malacca, Luzon and Taiwan Straits.
Model A is an extended model, used to simulate offshore boundary conditions (tidal,
storm surge, wave, current generated by wind, etc.) for coastal study areas. The spatial
-

scope of Model A was chosen broadly enough to ensure that the effects of uncertainty at
the open boundary to the main study area were minimized. In this study, model A covers
an area of about 130 km diameter around the LMD coastline of from Dong Ho Lake
(RachGia Province) to Long Hai cape (Vung Tau Province). The bottom of the seabed at
about -67.2 m÷3.29 m.

measures. The open boundary data for the model B are extracted from the results of
model A simulation.
Because the actual data is only within the range of model A, this report only presents
calibration and validation results for the RCM Model and Model A. The parameters of
model A are also used for model B.
4.2. DATA USED
4.2.1. Wave model setup of the whole South China Sea
Forecast tidal levels are used at open boundaries of the model. These tidal levels were
predicted based on the harmonic constituents obtained from the analysis of global tidal
data monitored with satellites and corrected with real measured data. All datasets are
integrated within FES2014 database.
Wave heights, periods, frequencies, directions for the Malacca, Luzon and Taiwan straits
are extracted from WAVEWATCH-III database.
4.2.2. HD and sediment transport modeling in the extended study area
Upstream open boundaries at river estuaries are 7discharge boundaries. Two of
discharge boundaries are located near the hourly observed station so they are provided
with real discharge data. For the 5 other boundaries, flow data are generally extracted
from the results of the 1D hydrodynamic model (MIKE11). The mentioned above 1D
model has been established, calibrated, validated and used by the SIWRR in different
research projects in the recent several years, so the model is highly reliable. In the wave
model, these boundaries are assumed to be closed boundaries (land or wall boundary).
4.2.3. 2D Hydrodynamic and sediment transport model in the detailed study area
For upstream discharge boundary, the discharge data used are similar to model A. For
the seaward open boundaries, water level data used are extracted from simulation results
of model A.
For the wave model, seaward open boundaries are extracted from the wave simulation
results of model A. Upstream boundaries are also assumed to be Land Boundary (Closed
Wall).
4.2.4. Topographic data
The topographic data used in this study were inherited from different sources and earlier
researches:
For estuarine areas (Soai Rap, Cua Tieu, Cua Dai, Ham Luong) and coastal areas of Go Cong, Can Gio and the Ganh Rai Gulf, the topographic data is extracted
-

from the surveying reconnaissance of 1/5.000 scale topographic plane. In the
years 2008, 2009, and 2010, under the framework of the Baseline Survey Project
implemented by the SIWRR and the ICOE as well as survey work-package of this
research.
For coastal areas from HCMC to Kien Giang, the topographic data was extracted from the map (scale of 1/100,000) published by the Navy in 1982.
The topography in other areas of the South China Sea was extracted from the SRTM30_PLUSV6.0 database from the Scripps Institution of Oceanography,
Californian University, USA. This is a dataset with 30"×30" resolution, constructed
from the satellite-gravity model, in which the gravity-to-topography ratios are
corrected by 298 million ADCP depth points.
4.2.5. Wind field data
Wind field data is the most important input parameter for the wave computation model.
The background wind data used in this study derived from the modeling results of the
Climate Forecast System Reanalysis (CFSR) of the National Center for Environmental
Prediction, the part of the US National Oceanic and Atmospheric Administration
(NCEP/NOAA). The wind field results obtained from the “reanalysis” simulation, which includes the model validation with the measured data from the global marine observation
stations system so the data should be highly reliable. This wind field data is from 1979 ÷
2009 with a time step of 1 hour and a grid size of 0.312o×0.312o. This is a very good
dataset for the wind and weather research. Wind speed (NCEP) [m/s]Wind speed (Observed) [m/s]

4.2.6. Wave field data
The wave and wind data collected at Bach Ho drilling platform in 1996 was collected for
the model calibration and validation purposes. The wind data used to verify the reliability
of wind data extracted from the CFSR model. The wave data used to verify the
TOMAWAC model.
The satellite-monitored wave data used to calibrate the South China Sea model in this
research was provided by France's AVISO organization. Concretely, the datasets are
combined in Ssalto/Duacs wave-field toolset (compiled from wave monitored by different
satellite system such as Jason-1 and Jason-2, Topex/Poseidon, Envisat, GFO, ERS-1
and ERS-2, and Geosat). This data only includes significant wave height, with a time step
of 1 day, a coarse 1o×1o space grid, and is available from September 14, 2009 to present.
The wave simulation results of the WAVEWATCH-III model used for comparison with the
TOMAWAC results are also provided by NCEP/NOAA. This dataset includes such wave

components as significant wave height, maximum wave period, and average main wave
direction. The data has a time step of 3 hours, 0.5o×0.5o space grid, available from 2005
to present.

5.1. WAVE AND CURRENT MODEL CALIBRATION
To calibrate and validate the TOMAWAC wave model for the whole South China Sea
(SCS) domain, we compare the wave results pattern from the SCS model with the
following wave data: (i) Observed wave data from the satellites of France's AVISO
organization, and (ii) Wave pattern simulated using the WAVEWATCH-III model of the
NCEP/NOAA in the US.

For the current calibration of the South China Sea we use the FES2014 H and UV values
at certain points in the deep water (P1-P56) and certain points located near-shore or
around islands (Kolak, Tioman, Kuantan, Cendering, Curimao, Bintulu, Phu Qui, Con

6. CONCLUSIONS
With nesting approach, TELEMAC2D and TOMAWAC has been calibrated well from the
Regional (South China Sea) Model to Extended Model with water levels, discharges,
tides, waves and currents, especially the validation results based on the in-situ data of the
LMDCZ project in October 2016 and February-March 2017. The hydrodynamic regimes
were simulated to understand the hydrodynamics of the LMDCZ and ready for creating
the boundary conditions for the detail study areas of Go Cong.
