Title of Paper : A New Record of Sediment Accumulation Rate in Sayung Coast, Demak, Central Java Using Unsupported ²¹⁰Pb Isotope

Comment on Descriptions 1. Title

[ ] Appropriate [ x] Should be changed

“A New Record of….” has no significant meaning. It is only to indicate that it is a new study then should be erased or paraphrased.

2. Abstract

Yes[x] No[ ] Is the length reasonable?

Yes[ ] No[ ] Is it an appropriate summary of the content?

Yes but it needs to be rearranged or paraphrased because it is mixed up the background information and the results.

3. Main Text

Yes[ ] No[ ] Is there anything new in this work?

Yes: application on new location

Yes[] No[ ] Is the relation to previous studies adequately stated?

Need to add previous studies regarding current technique (sediment accumulation technique) in other locations such as those conducted by BATAN. Previous studies regarding the study area are appropriate.

Yes[ ] No[x] Are the assumption(s) and/or method(s) described comprehensively?

The author need to add some formulas he/she used to find the results Yes[ ] No[ ] Are the new results adequately emphasized?

Line # Referee’s Comments

1-3 “A New Record of” in the title has no significant meaning. It is only to indicate that it is a new study, then it should be erased or paraphrased.

11-13

Abstract:

- The two beginning sentences in the abstract are only background information and they are not part of authors research. Please start the abstract by a sentence that explaining or the result of your study.

- 3^rd sentence: “Some efforts have been measured……..” please explain what do you mean by the word “measured”.

- 3rd sentence: “Some efforts have been measured to cope with these hazards……..”

please elaborate the hazards.

- 5^th sentence: “This study aimed to determine……….., sediment sources analysis,

…” I hardly see discussion about sediment sources analysis in this paper.

- 6^th sentence: “The supported ²¹⁰Pb sediment accumulation rates…………” please paraphrase this sentence because it is not very clear either it refers to ²¹⁰Pb accumulation rates or sediment accumulation rate.

- 9^th sentence: “This increased to around 0.4 cm/year in 2016 in………….” the subject of the sentence (“This”) is not very clear to what it refers to.

- 10^th sentence: “Normalization of rivers ……….” It this is not the results of your study (only suggestion) then don’t put it as a part of your abstract.

- The last 2 sentences has no any significant meaning, hence, can be omitted.

25-26 Please change “area” to “land” and “reached” to “has reached to” in “The total eroded area………reached 495.80 ha [4].”

27-29 Please be consistent to use plural or singular. Please change “environment” to environments” in “This erosion……….

(5)

48 - 58 Please use appropriate “tenses” past or present was instead of is.

55 “wide-spreading of” ”wide spread”

99 If all the 3 morphological units have been mentioned then the word “including” is not appropriate in this sentence.

112 Use common conjunction word instead of “After that, …”

118 “unique geology”  “unique geological formation”???

127

“EXPERIMENTAL METHOD”  “METHODOLOGY”

Subsection to how you determine the sediment accumulation rate (model, formula, steps) should be added in this section because it is the main discussion in this study.

174 MSE  RMSE 180 -

186 These sentences should be moved to “RESULTS and DISCUSSION”

193

“Flow Model Simulation” Why is this subsection to be elaborated here? What is the purpose of this flow model simulation, because this flow model simulation is not discussed in the

“RESULTS AND DISCUSSION”. If it is discussed in “RESULTS AND DISCUSSION”

then please mentioned it. If Figure 4 is the output of this simulation model then you should mentioned it explicitly.

203- 205

“To develop hydrodynamic model, ……..” does it mean that you develop hydrodynamic model?

215

…………the model developed.  ………the developed model.

Which one do you mean the developed model? Did you develop any model by your self in this current study?

225- 227

Be careful to use the term “accelerates” the unit of acceleration is m/s² not m/s. You may consider this instead:

“During high tide, the surface current can reach up to 0.41 m/s………”

269- 273

Figure 4: Keep the title of the figure as simple as possible Background information (findings) can be discussed in text of the manuscript.

278 ……….Bq.kg-1 respectively.  …………Bq.kg-1, respectively. Always put comma before “respectively” (check other sentences).

277 -

… Bq.kg-1???  Bq/kg 281-

283

“The unsupported …….the unstable ……….those two analysis period.” Please be clear about the meaning of the unstable value and two analysis period?

286 Please refers to previous comment to find correct word for “including”.

285 -

…

Please explain what LS1, LS2, etc and mixing layer means. To help the readers, please give an example to how you divide the layers based on the data. Please rewrite cm.y-1 to cm/y 301-

302

CIC model please elaborate this model in “METHODOLOGY”.

There is no Table 2.

348 Figure 6. Again, to help the readers to understand the study, please elaborate how do you convert ²¹⁰P radio activity to years (give an example case from your data”.

351 What do you mean by “The acceleration of sedimentation rates”? Why don’t you use simply

“sedimentation rate” instead?

386-

388 Please recheck this sentence either it has grammatically correct or not 389 Please use consistent terminology sedimentation or sedimentation rate

(6)

434-

436 “Based on ………..observation stations.” Please correct this sentence.

436- 439

Is it widely accepted the terminology “the sediment accumulation decreased” is called erosion? Please give reference here.

453- 474

“CONCLUSION”

- The conclusion so short compared to very long discussion in “RESULTS AND DISCUSSION”.

- Some values are not matched between those in “RESULTS AND DISCUSSION” to those in CONCLUSION i.e., in line 329 – 330 the sedimentation rates for

Timbulsloko was written 0.15 and 0.14 cm/y but in the CONCLUSION was written 0.06 cm/y.

Final comments and recommendations:

Major revisions are needed if the manuscript to be accepted:

a. There are still many grammatically errors, in the writing b. The abstract is not yet properly written

c. Subsection to how the author to determine the sediment accumulation rate need to be added in “METHODOLOGY”

d. Physical units are not written properly and consistently i.e., Bg.kg-1 etc

e. Table 2 is mentioned in the discussion, but it is not included in the manuscript.

f. Many uncommon terminologies have been used i.e., acceleration rate???

This paper is recommended to be [ ] Accepted without further revision [ ] Accepted with minor revision [x] Major Revision is required [ ] Rejected
