Author Response
The authors have simulated hydrodynamics and sediment transport phenomenon near delta formations in three rivers. It is indeed a challenge to the river engineers to simulate the tidal mechanism. However, the English language need to be polished before publishing some of them are listed below.
Thank you for your review. The English language has been edited. You could see the certificate in attaching document. If you have additional suggestions, please do not hesitate to contact me.
L17, P1- sand sediment?
Thank you for your review, I have changed the "sand" to "and".
L19, 145- ‘to analyse’ not ‘to analysis’
Thank you for your review. I have changed this word.
L51- 1 x 108 t : not understandable
Thank you for your review. t means tons in 1 x 108 t, 1 x 108 t means 100000000 tons.
Study area map must be included.
Thank you for your review. I have insert the study area map in method.
Units in the introduction section is difficult to understand.
Thank you for your review. In imtroduction, t/a means tons per year, km2/a means means square kilometers pear year. If you have any units is difficult to understand, please do not hesitate to contact me.

Reviewer 2 Report
The estuary delta is an area with active human economic activities and fragile natural ecological environment. With the intensification of global changes and human activities, the coastal and seabed erosion around the world is becoming more and more serious. This paper compares the hydrodynamic effect sand sediment diffusion path at the Yellow River subaqueous delta (river control type) and the Yangtze River subaqueous delta (tide-river type) in the East Asian monsoon area through Delft 3D numerical simulation to analysis the causes of the distribution of accumulation and erosion landform in the different types of subaqueous delta. Yet, I found the manuscript having several weak points:
1. The description of Line 179-185 should not be in the results.
2. The references of this manuscript are too few.
3. The first paragraph of the introduction is only one sentence, too thin.
4. The inadequacies of the research area are poorly described in the introduction.
5. The introduction should describe the novelty of the paper.
6. The content of model validation 2.3 should be placed in the results.
7. The figure in the manuscript is too small and needs to be enlarged.
8. Line 327-329 in the discussion, the authors should explain the reason for this phenomenon.

The estuary delta is an area with active human economic activities and fragile natural ecological environment. With the intensification of global changes and human activities, the coastal and seabed erosion around the world is becoming more and more serious.

Yet, I found the manuscript having several weak points:
Point 1: The description of Line 179-185 should not be in the results.
Response 1：Thanks for your suggestion. I have put the Line 179-185 to Line 100-107 in introduction, and add new references in the sentence.
Point 2: The references of this manuscript are too few.
Response 2：Thanks for your suggestion. I have added new references in Line 36-45 and Line 77-107.
Point 3: The first paragraph of the introduction is only one sentence, too thin.
Response 3：Thanks for your suggestion. I add content in the first paragraph in Line 36-39.
Point 4: The inadequacies of the research area are poorly described in the introduction.
Response 4: Thanks for your suggestion. I spend a lot of space introducing the influencing factors of delta erosion because of this paper intends to build a model that simulating the combined effect of the sediment diffusion and hydrodynamic in East Asian estuary through simulation technology to identify the formation mechanism and control factors of the erosion and accumulation landform at the three different types of major estuary deltas in East Asia. After getting your advice, I add sentences to introduce the inadequacies of the research in 108-118.
Point 5: The introduction should describe the novelty of the paper.
Response 5: Thanks for your suggestion. After getting your advice, I add sentences to describe the novelty of the paper in Line 120-129.
Point 6: The content of model validation 2.3 should be placed in the results.
Response 6: Thanks for your suggestion. According to your suggestion, the content of model validation 2.3 and 2.4 have been placed in the results.
Point 7: The figure in the manuscript is too small and needs to be enlarged.
Response 7: Thanks for your suggestion. According to your suggestion, The Figure 7, 8, 9, 13 have been enlarged.
Point 8: Line 327-329 in the discussion, the authors should explain the reason for this phenomenon.
Response 8：Thanks for your suggestion. In the early winter, the downstream water surface is frozen while the upstream water surface is not frozen, resulting in water storage in the upper reaches of the Yellow River. When the downstream ice surface is broken, the upstream storage water flow out form “Winter Flood”. The explanation has been added in Lines 363-366.
Thank you for your suggestion. If you have additional suggestion, please do not hesitate to contact me.

Round 2
Reviewer 1 Report
There are some minor corrections are required as follows:
L75: magnitude still not correct
Do not start the sentence with ‘And’ e.g. L36, and some other paces also need to be corrected.
I did not find any English editing certificate from professional editing agency.

Point 1: L75: magnitude still not correct
Response 1: Thank you for your suggestion, I have revised the magnitude in Line 74 and 76.
Point 2: Do not start the sentence with ‘And’ e.g. L36, and some other paces also need to be corrected.
Response 2: Thank you for your suggestion, I have revised start the sentence with ‘And’ in Line 36, Line 80, Line 101, Line 122 and Line 141.
Point 3: I did not find any English editing certificate from professional editing agency.
Response 3: Thank you for your suggestion, I am sorry for unproviding the English editing certificate in the previous revision. In this revision, I have attached the certificate in the attachment.
