- Table — final selected geometry for every element: dimensions, thickness, grade, spacing, elevation
- Table — inlet, pipe, culvert and outlet sizing with slope, capacity and headwater depth
- Table — ultimate limit state check summary: demand, capacity, ratio, pass or fail, governing clause
- Table — serviceability check summary: deflection, crack width, settlement, freeboard or velocity against its limit

- Figure — hydraulic grade line and energy grade line profile
Equations — at least 8
- Equation — equilibrium equations written out for each free body (sum of forces and sum of moments, or continuity and energy)
- Equation — the internal force relations V(x) and M(x), or the momentum/thrust relation, used to compute each element's demand
- Equation — the resulting demand at the critical section of each element, with numeric substitution
- Equation — the capacity expression for each element type, shown with full numeric substitution and units

- Equation — each limit state check written as demand over capacity with numbers substituted
- Equation — the factor of safety calculation for each failure mode checked
- Equation — outlet scour velocity and riprap sizing check
Number every table and figure (Table 4.x, Figure 4.x), caption it, and refer to it by number in your text. Number displayed equations and show the substitution with units. These counts are minimums — add whatever else your design needs.
Engineering documentation standard — required in every Chapter 4 subsection
These rules are graded on every subsection. Work that misses them is capped on technical accuracy, exhibits, codes and communication, whatever the quality of the prose.
Code and standard references
- Every requirement, factor, coefficient, limit and allowable you apply cites the governing document AND the exact section, article or sub-article number — e.g. ACI 318-19 §22.5.5.1, AISC 360-22 Chapter J, Section J3.6, AASHTO LRFD 10th Ed. Article 3.6.1.2.2, ASCE 7-22 §12.8.1, ASTM D2487, state DOT manual section, local stormwater manual chapter.
- Give the edition or year of every document the first time it appears, then use a consistent short form.
- Where a code equation is used, quote the equation number (e.g. Eq. 22.5.5.1) next to your displayed equation.
- Where you depart from a code provision, state the clause you are departing from and the engineering justification.
- List every code, standard and manual actually used in a Codes and Standards table at the start of the subsection.
Citations for statements
- Every statement of fact, value taken from elsewhere, material property, soil parameter, rainfall depth, unit cost or published method carries an in-text citation (APA) to its source.
- Field and lab data cite the report, boring log, gauge, survey file or test number and its date.
- Manufacturer data cites the product literature and revision date; software results cite the program, version and model file name.
- Uncited assertions are treated as assumptions and must appear in the assumptions table with a justification.
- Every in-text citation resolves to a full entry in the reference list.
Step-by-step calculations
- Structure every calculation the same way: (1) objective, (2) governing code clause, (3) equation in symbolic form with the equation number, (4) definition of each symbol, (5) numerical substitution, (6) result with units, (7) comparison against the limit and the pass/fail statement.
- Show the substitution line — never jump from the formula to the answer.
- Number displayed equations sequentially (Eq. 4.1, 4.2, …) and refer to them by number in the text.
- State the load or flow combination governing each calculation by name.
- Carry consistent significant figures and round only at the reported result; state the rounding convention once.
- Present repetitive element checks in a calculation table with one row per element and the same column order throughout.
Free body diagrams and figures
- Draw a separate free body diagram for each isolated element — no combined sketches standing in for several members.
- Dimension every FBD: span, depth, thickness, cover, eccentricity, embedment, slope, pipe diameter, wall height — with the dimension lines and values shown.
- Label every force, pressure, reaction and moment with its symbol, magnitude and units, and show the sign convention and coordinate axes.
- Show supports and boundary conditions explicitly (pin, roller, fixed, elastic, buoyant, hydrostatic).
- Accompany each FBD with its shear, moment, thrust, pressure or hydraulic grade diagram at the same scale reference.
- Number and caption every figure (Figure 4.x) and refer to it by number in the narrative; add a scale or north arrow to plans.
Units and notation
- Every number in text, tables, figures and equations carries its unit — no bare numbers.
- Use one unit system throughout (US customary or SI); if both appear, give the converted value in parentheses consistently.
- Check dimensional homogeneity of each equation and say so — the units of both sides must match.
- Provide a nomenclature table defining every symbol with its unit.
Checking and verification
- Every calculation is checked by an independent route — hand check against software, alternative method, order-of-magnitude estimate, or a published worked example — and the check is shown, not just claimed.
- Report demand-to-capacity ratios and factors of safety against the required values, with the source clause for each required value.
- Include a verification/checking table: item, method of check, expected, obtained, difference, accept or revise.
- Sanity-check every result (magnitude, direction, plausibility) and state the conclusion.
- Record who checked the work and on what date; flag anything still unverified as an open item.
- State limitations and the range over which the result is valid.

Section B
Engineering story
A real project situation that frames this module
A water resources engineering team hits water resources design submission in week 6, with the hydrologic and hydraulic model with the sized conveyance already promised to the owner. Compile and submit the complete water resources design chapter for advisor review. The reviewer starts at the end and works backwards, and the chain breaks at calculation package organization and cross-referencing to drawings and models.
Submitting a model file that does not match the reported results in the calculation package. Because independent design check documentation and sign-off, the error does not stay local: it is carried into the design of record that drawings, quantities and cost are generated from, and every downstream product inherits it before anyone notices.
Downstream property owners, emergency responders and the utility carry the consequence. On this module specifically, the exposure runs through basis-of-design narrative summarizing design storms, standards, and controlling decisions, and the cost of correction rises every week the hydrologic and hydraulic model with the sized conveyance moves closer to issue.
Decisions the engineer must make
- What record establishes calculation package organization and cross-referencing to drawings and models, and is that record in the project data inventory?
- Does FHWA HEC-22 (3rd Ed.), N/A, govern here — and is that the edition adopted by the jurisdiction?
- What is the acceptance criterion for independent design check documentation and sign-off, and was it written before the result was known?
- Is the documented procedure valid for the conditions this project actually presents?
- If the check fails, does the team revise the hydrologic and hydraulic model with the sized conveyance or raise a change request against the locked baseline?

Section C
Why this matters
Professional
A licensed engineer defending water resources design submission cites FHWA HEC-22 (3rd Ed.), N/A, and shows the record behind each input. Your complete water resources design submission package with calculations, models, drawings, and basis of design. is reviewed the same way — traceability is assessed before arithmetic.
Technical
Calculation package organization and cross-referencing to drawings and models controls the numbers this module hands forward. Independent design check documentation and sign-off determines whether those numbers remain valid once conditions change.
Safety
The failure mode this module guards against is a conveyance or storage element overtopped by the design event. It reaches people through version control and submission record-keeping, which is why the safety check is recorded explicitly here rather than inferred from a passing strength or performance check.
Economic
The design of record that drawings, quantities and cost are generated from is priced from this work. Quantities, unit costs and schedule float all trace to calculation package organization and cross-referencing to drawings and models; a late correction here is paid for as a change order, not a redline.
Environmental
Environmentally, this module fixes receiving-water quality, channel erosion and altered baseflow. Choosing conservatively without justification is not free — the excess shows up as material, energy and land that the project consumes for no measurable gain.
Community
Households and businesses in the floodplain the design is meant to protect inherit whatever this module decides — performance, accessibility, cost of ownership and resilience are set here, not at the ribbon-cutting.
Section D

Instructional content
Full lecture notes with figures and governing equations
Water Resources Design Submission: from proposal statement to engineering product
Compile and submit the complete water resources design chapter for advisor review. That single sentence hides the substance of the module: calculation package organization and cross-referencing to drawings and models, and independent design check documentation and sign-off. Both must be established from project evidence before anything downstream is credible.
In water resources engineering, this work is the input to the hydrologic and hydraulic model with the sized conveyance. Basis-of-design narrative summarizing design storms, standards, and controlling decisions — which is why this page asks you to record the source of every quantity, not just its value. The design of record that drawings, quantities and cost are generated from depends on it.
- Calculation package organization and cross-referencing to drawings and models
- Independent design check documentation and sign-off
- Basis-of-design narrative summarizing design storms, standards, and controlling decisions
- Version control and submission record-keeping

Decision logic: the procedure that replaces a closed-form solution
Water Resources Design Submission is governed by a documented procedure rather than a single expression, so the decision logic is the deliverable: what you accept, what you reject, and on what evidence. Calculation package organization and cross-referencing to drawings and models.
Write the acceptance criterion before you look at the result. Independent design check documentation and sign-off — recording the criterion afterwards lets it be shaped to fit the number you happened to get.

Constraints, adopted standards and the safety case for water resources design submission
FHWA HEC-22 (3rd Ed.), N/A, governs this module: Governing standard referenced across the chapter
The safety case is explicit here. The failure mode is a conveyance or storage element overtopped by the design event; the people exposed are downstream property owners, emergency responders and the utility; the control that prevents it is version control and submission record-keeping together with an independent check by someone who did not perform the work.
- Controlling criterion for this module: calculation package organization and cross-referencing to drawings and models.
- Adopted reference: FHWA HEC-22 (3rd Ed.) — cite N/A by number.
- Failure mode guarded: a conveyance or storage element overtopped by the design event.
- Evidence produced: Complete water resources design submission package with calculations, models, drawings, and basis of design..

Where this method stops being valid
Every method has a domain of validity. State the range of geometry, loading, material behaviour or flow regime over which your approach holds, and state what you would do instead beyond it.
For this project, the boundary you are most likely to push is version control and submission record-keeping. If you cross it, say so in writing, bound the error, and carry the limitation into your results chapter. A disclosed limitation is professional practice; a silent extrapolation is not.

Engineering workflow
Steps
- 1. Assemble the inputs this module needs — calculation package organization and cross-referencing to drawings and models; independent design check documentation and sign-off — each with a unit and a source record.
- 2. Confirm FHWA HEC-22 (3rd Ed.) is the adopted edition and locate N/A.
- 3. State the assumptions and the acceptance criterion for calculation package organization and cross-referencing to drawings and models.
- 4. Execute the documented procedure, recording each judgement and the evidence behind it.
- 5. Test the result against basis-of-design narrative summarizing design storms, standards, and controlling decisions.
- 6. Audit units and run an order-of-magnitude check by hand before the number leaves your desk.
- 7. Obtain an independent check from a teammate who did not perform the work, and record their name and date.
- 8. Assemble complete water resources design submission package with calculations, models, drawings, and basis of design. and submit it to the floodplain administrator for review.
Decision points
- Is every input behind calculation package organization and cross-referencing to drawings and models traceable? If not — stop and collect the record.
- Does the result satisfy independent design check documentation and sign-off? If not — revise the work, never the criterion.
- Would the correction change the design of record that drawings, quantities and cost are generated from? If yes — raise a change-control request before proceeding.
- Have you ruled out the most common error on this module — submitting a model file that does not match the reported results in the calculation package?

Common mistakes and how to avoid them
- Submitting a model file that does not match the reported results in the calculation package
- Omitting the independent checker's name and date
- Missing a basis-of-design narrative tying design storms and standards to the final decisions
- Treating calculation package organization and cross-referencing to drawings and models as a given instead of establishing it from a project record.
- Producing complete water resources design submission package with calculations, models, drawings, and basis of design. without showing how independent design check documentation and sign-off was satisfied.
- Recording the outcome of this module without recording the judgement and evidence that produced it.
- Missing version control and submission record-keeping, which is exactly the path to a conveyance or storage element overtopped by the design event.
- Designing to the average condition when the governing condition is the controlling one.
- Freezing a design before the constructability and access review that would have changed it.
- Omitting the safety check because the strength check passed.
- Referencing figures, tables, or sources that never appear in the reference list.
- Carrying an assumption forward after the governing condition changed, without re-checking the result.

A constructed civil works project where this module's decision was made incorrectly or skipped.
Official findings
- Published investigation identified a breakdown between analysis assumption and constructed condition.
Field observations
- The controlling assumption was documented nowhere in the design record.
- No independent check existed at the stage where the error entered the work.
Engineering interpretation
- Interpretation below is student analysis for instructional purposes, not an official finding.
- Map the failure to a step in your own workflow and state where your process would have caught it.
