2.2. Stage of 3D numerical modeling

Modeling activities have continued to establish ways to improve the application of Delft3D

model by local adjustments in the bottom sill area, given the measured data sets. The conducted

numerical simulations aimed to establish the necessary elements for the development and

recalibration of Delft3D model for current conditions, with a better substantiation based on

measurements from the period from autumn 2013 until the first half of 2014.

Calculations were performed with Delft3D model regarding the water flow parameters at

critical point 10, based on data from June. Completion of datasets for modeling continued by

processing the results of measurements carried out in June conditions.

2.2.1. Numerical simulations for Delft3D model aplication improvement, in actual

conditions in bottom sill area

An important part of the bottom sill effect on water flow parameters result using

calculation methods applied within Delft3D model and the additional structure option has a role of

completing the calculation of these effects.

Bottom sill effect on the water level was calculated with different Delft3D models and the

results were analyzed based on measured data sets. Simulations were conducted for local section

of the first part of Bala branch and used various vertical discretizations.

Measured datasets based on which the numerical simulations results were analyzed, refers

to situations with relatively low flows to an average, over 2500 m3/s Bala branch and below 4000

m3/s.

For data regarding the flows measured in March (situations marked with a and b) were used

recent data from May regarding riverbed configuration on local sector near the bottom sill. For

situations from previous months, with flow rates from the end of 2013 and beginning of 2014

(situations marked with 1, 2, 3, 4, 5) has been used bathymetric data from December 2013.

Simulations carried out with Delft3D models sigma type, without structures option, shows

that in order to achieve more accurate results on water level differences between the ends of the

sector, it would be useful a very fine discretization.

With the structures option at the bottom sill and in old section, a usual Delft3D model

sigma type can be locally adjusted so as to provide better results regarding water levels. This is

shown by the results of simulations for the situations in March (a and b), in addition to the results

presented above for other studied cases. It is found that with finer vertical discretization and at

riverbed level (which however requires larger memory resources and increase the duration of

calculation), the necessary adjustment of the model through structures option can be reduced.

This adjustment remains necessary to obtain calculated levels upstream and downstream near

those highlighted by measurements. Otherwise, there is a need for other local changes in the

model in order to obtain adequate levels.



33

Figure 2.2.1 – Relative differences of water levels in the sector with bottom sill at Bala, results for relatively low flow with Delft3D models sigma type, with different vertical discretizations, without structures option

Figura 2.2.2 – Relative differences between the water levels at the ends of sector with bottom sill on

Bala branch, results at average flows with Delft3D model sigma type, with structures option at the sill and old section

Placing the structures in slightly different positions within the grid has a very little

influence on the results of water levels upstream and downstream from the bottom sill.

Considering that for the riverbed roughness representation may occur changes, in order to

make local adjustments of the model, have been taken into account also different roughness

values on the analyzed section. It is found that the effects of usual roughness modification are



34

practically separate from those of structures option.

Numerical simulations performed with Delft3D models of z type, with horizontal layers,

without structures option, revealed that in order to get more accurate results regarding water

levels would be useful a finer discretization.

Figure 2.2.3 - Relative differences between the water levels at the ends of sector with bottom sill on Bala branch, results at a relatively low flow of Delft3D model of z type with different vertical disctretizations,

without structures option

Using additional option of structures at the bottom sill and at old section, the results show

that an usual Delft3D model of z type can be adjusted locally in order to provide more accurate

results on water levels in different situation.

Figure 2.2.4 - Relative differences between the water levels at the ends of sector with bottom sill on Bala

branch, results at relatively low to medium flows, of Delft3D models of z type with different vertical discretizations, with structures option at bottom sill and in old section

The results of Z type non-hydrostatic models, with different vertical discretizations show,

for a relatively low water flow, differences in water levels at the ends of the sector that are

similar with those obtained with Z hydrostatic models.

branch, results at relatively low to medium flows, of Delft3D models of z type non-hydrostatic with different vertical discretizations, without structures option

2.2.2. Simulation with Delft3D model for water flow parameters in critical

point 10, in flow conditions from June

Simultation results with Delft3D model have indicated a flow percentage value on Danube

slightly lower than flow percentage on Caleia branch, the two values being relatively close.

This situation is similar to those previously observed, showing that the works performed at

the critical point 10 had significant effects in terms of flow distribution balancing on Danube

compared to Caleia branch.

Velocities distributions obtained by numerical simulation in critical point 10 area, upstream

from the entrance on Danube sector near Caleia branch, indicates values usually found on other

sectors of the Danube.

The distribution of calculated velocities in a section upstream from Caleia branch highlights

the effects due to water flow towards the two sides of the island and respectively the flow

influence on Valciu branch. The values distribution is similar to that obtained based on velocities

and flow measurement through a very close section. The measured values contain also fluctuations

due to water flow turbulence.

2.2.3. Completing the data for modeling

Processing activities for data measured on Danube and preparing the data sets and files in

a usable form for modeling have included the following:

Preparing the data for each section, regarding flow and velocity distributions

measured in main critical points areas.

Preparing the data sets for measured cross-sections representation and those

regarding bathimetric measurements on various trails for the riverbed.

6. CONCLUSIONS, RECOMMENDATIONS, WARNINGS

5.1 This Monthly Report reflects the monitoring activities in June 2014.

5.2 For the specific monitoring objectives within this phase, the Provider respects the field and

laboratory activities, logistics and infrastructure be made according to the graphics and

stipulations mentioned in the Specifications.

5.3 Taking into consideration the importance of the construction works that take place on

Danube, on the section between Calarasi and Braila, the Consortium recommends further

actions on biodiversity monitoring, with the frequency related with the post-construction

stage, up to end of the project, in order to ensure an informational volume, with a high

confidence level, to allow if necessary, the development of preventive solutions.

5.4 ADCP measurements performed in June in Bala branch area confirmed the phenomenon of

erosion pit expansion, developed behind the bottom sill, to the right bank (phenomenon

shown by the bathymetric monitorings in previous months and especially by multi-beam

measurements made in May).

Irregular geometry of the riverbed and bottom sill leads to the occurrence of strong vortices

that cause problems to navigation in bottom sill area. At the same time, ADCP measurements

in the bottom sill area highlight the high water velocities.

5.5 Regarding sturgeons situation, we specify that during May were recorded three starry

sturgeon specimens that swim against the current over the new bottom sill built on Bala

branch. So far, our researches have not noticed problems regarding migration or for the

possibility to swim over the hydrotechnical construction.

5.6 Bala branch medium flows calculated at the time of passing of the three specimens of starry

sturgeon were:

- 5300 m3/s on 18.05.2014, for starry sturgeon with code 7S47;

- 5650 m3/s on 20.05.2014, for starry sturgeon with code 7S43;

- 5780 m3/s on 26.06.2014, for starry sturgeon with code 7S22bis.

Figures bellow presents migration maps for those 3 starry sturgeons:
