Urban Multi-Source Water Supply in China: Variation Tendency, Modeling Methods and Challenges

Round 1

Reviewer 1 Report

This is a review paper about the problem of optimally scheduling urban water resources.  My concerns about the paper are the following:

Tianjin is referred as a “typical city” for discussing the problem but then authors state that “At present, Tianjin has the lowest per capita water resources in mainland China, and it is far off the average level of the world.” This seems to be a contradiction.

Major software vendors that provide optimization software are omitted in 3.3.2.: IBM ILOG CPLEX, Gurobi, XPressMP. Also, what about open source software?

No reference to the EPANET software tool is made (https://www.epa.gov/water-research/epanet) in section 3.3.2.

There are too many references (117). Some of them are about methods and tools that can be considered dated.

There are grammatical and syntactical errors spread across the text. Proofreading is needed.

Some sentences can be improved to better convey the intended meaning. See bellow.

 

Other remarks:

• Subfigure d in figure 1 is about domestic water, again.
• Page 4, line 155: Grondwater ==> Groundwater
• Page 4, line 156: in Typical City ==> in a Typical City
• Page 4, line 169: Up ==> up
• Page 5, line 197: perfection might not be the adequate word for describing the raise of the water prices 12 times in 17 years.
• Page 6, lines 246-247 ==> text is incomprehensible
• Page 6, line 248: the water plants is ==> the water plants are
• Page 6 and 7, lines 254-259: delivery ==> deliver
• Page 7, line 284: a word is missing after and
• Page 7, line 299: the word representing is written twice
• Page 8, line 321: In recent years … China ==> improve text
• Page 8, line 333: the word and is written twice
• Page 8, line 347: Summary … supply ==> improve text
• Page 9, line 401: and it had global ==> improve text
• Page 13, line 595: An high ==> A high
• Page 14, line 621: At last ==> Finally
