Appendix C.5:   Hydrologic process modules of the Regional Simulation Model: An Overview General comment:   This paper contains some important concepts which are not detailed in the main body of the Theory Manual. You may want to consider eventually placing some of this material within the main body of the Theory Manual. This paper contains certain grammatical and other errors that need to be corrected before the document is presented in final form (see below). Page 1, Abstract:   Word "regional" in the first line is redundant. Page 1, Abstract:   Replace "surface water" with "surface-water" Page 1, Abstract:   "Replace "additional functionality is required" with "additional functionality is envisioned" Page 1, Abstract:  l; Replace "There are Hubs" with "In addition, there are Hubs" Page 2:   Review and apply consistent spelling of "south Florida" throughout. Page 2:   Is the used approximation, which neglects the inertia terms, named "diffusive wave" or "diffusion wave" or "diffusion flow"? Be consistent throughout the report (Theory Manual). Page 3, paragraph 1:   Avoid the use of the first-person pronoun "we" Page 4, paragraph 2:   Replace "explicitly define" with "explicitly defined" Page 5, paragraph 1:   Replace "right hand side" with "right-hand side" Page 5, paragraph 2:   Replace "local detention storage components" with "local detention-storage components" Page 7, paragraph 2:   Replace "landuse" with "land-use" (several instances) Page 7, section 3.1, paragraph 1:   Replace "surface water management systems" with "surface-water management systems" Page 8, section 3.2, paragraph 3:   Replace "process specific HPMs" with "process-specific HPMs" Page 9, section 3.3, paragraph 1;   "explicit solution for convenience and stability" Rationale is not clear, aren't explicit solutions conditionally stable? Page 9, section 4, bullet 1:   Replace "high water table soils" with "high-water-table soils" Page 9, section 4, bullet 4:   Replace "deterministic lumped parameter conceptual model" with "deterministic lumped-parameter conceptual model". Is the model is classified as deterministic, it cannot be conceptual; these are mutually exclusive terms. If it has components of both, then it is classified as deterministic-conceptual. Page 9, section 4, bullet 4:   Replace "where is apportioned" with "where it is apportioned" Page 11, paragraph 1:   Replace "dry season ET budgets" with "dry-season ET budgets" Page 11, paragraph 2:   Replace "generic crop correction factor" with "generic crop-correction factor" Page 11, paragraph 2:   Replace "reference crop potential evapotranspiration" with "reference-crop potential evapotranspiration" Page 11, Figure 4:   Replace "Water table Elevation" with "Water-table elevation" Page 12, Section 4.2:   Replace "except it considers" with "except that it considers" Page 13, paragraph 1:   Replace "vegetation specific reference vegetation PET correction coefficient" with "vegetation-specific reference-vegetation PET correction coefficient." Don't vegetation-specific and reference-vegetation contradict each other? Please clarify. Page 17, first sentence:   How is Imax determined? Page 18, paragraph 5:   Replace "lower zone storage" with "lower-zone storage" Page 18, paragraph 6:   Replace "upper zone storage" with "upper-zone storage" Page 18, last line:   Replace "root zone threshold value" with "root-zone threshold value" Page 20, section 5.1, paragraph 2:   Replace "soil moisture accounting" with "soil-moisture accounting" Page 27, Table 7:   What is the s attribute of agimp? Abstraction in the NRCS runoff method? Is it the potential storage (abstraction), commonly referred to as (capital) S? if so, the CN corresponding to S = 0.85 m is CN = 23. This value appears to be too low. Is this a good (central) value for South Florida? Page 29, Table 8:   What is the time duration of the depth attributes of the imperv HPM? One day? One time interval? Page 29, section 6.2, paragraph 1:   Replace "South Florid Water Management Model" with "South Florida Water Management Model" Page 30, paragraph 2:   How do you justify using the event-based NRCS runoff (curve number) method for hydrologic abstraction in continuous modeling? I know that this has been done in the past, but, is it generally justified? Page 31, paragraph 1:   How was Eq. 44 determined? How was the constant 0.5 in Eq. 44 determined? Page 31, Table 9:   How is time of concentration determined? Page 36, section 7.1, paragraph 2:   Replace "is described above in Section 5.1" with "was described in Section 5.1" Page 37, paragraph 2:   The sentence "The urban developments receive water from offsite public water supply wells (PWS), are self-served or have both where landscape irrigation comes from a local source." is ackward. Better state as "The urban developments receive water either from offsite public water-supply wells (PWS), or are self-served, or from both (PWS and self-served) in the case where landscape irrigation comes from a local source" I hope I have not changed the meaning. Please verify. Page 37, paragraph 3:   Replace "water storage capacity" with "water-storage capacity" Page 38, paragraph 1:   Replace "ignored" with "neglected." Provide additional justification for the statement "infiltration is assumed to be complete within a day." Page 38, paragraph 1: Replace "soil water storage" with "soil-water storage" Page 39, Fgure 16:   What is the temporal dimension of ET and runoff? Per day? Per year? Page 40, paragraph 3:   There is a danger of excessive reliance of NRCS runoff curve number to model conditions for which the model is known not to perform. NRCS is a design tool, not a continuous simulation tool. Its use in continuous simulation, for lack of a better or more convenient method, should be performed with extreme caution. Page 41, paragraph 2:   Equation 50 is dimensional, with the units of Lmax, 1000 and 10 given in inches. For usage in the metric system, the quantity 1000 and 10 need to be converted to the proper units (2540 and 25.4 for centimeters; 25.4 and 0.254 in meters). Please confirm that this is the case in this application. Page 42, section 10, paragraph 1: Replace "more functionality is necessary" with "more functionality becomes necessary"
