1Under Airy linear wave theory per JTS 145 (Code of Hydrology for Port and Waterway Engineering), which equation represents the exact dispersion relation relating wave angular frequency ω (= 2π/T), wave number k (= 2π/L), and water depth d?

A.ω² = g · k · tanh(k · d)

B.ω² = g · k · sinh(k · d)

C.ω² = g · k² · tanh(k · d)

D.ω = g · k · tanh(k · d)

Explanation: Per JTS 145-2015 Section 4.1, the linear wave dispersion relation derived from the kinematic and dynamic free-surface boundary conditions under Laplace's equation for irrotational, incompressible, and inviscid flow is ω² = g · k · tanh(k · d), or equivalently (2π/T)² = g · (2π/L) · tanh(2πd/L). In deep water where kd > π, tanh(kd) approaches 1, giving the deep-water dispersion relation ω² = g · k.

2A swell with period T = 10.0 s propagates from deep water into coastal shallow water where water depth d = 8.0 m. In deep water, the wave crest angle with straight seabed contours is α₀ = 45.0° and deep-water wave celerity is c₀ = 15.60 m/s. If the local wave celerity at d = 8.0 m is c = 8.20 m/s, what is the refracted wave crest angle α at this depth according to Snell's law?

A.21.8°

B.32.4°

C.15.2°

D.45.0°

Explanation: Per JTS 145-2015 Section 4.3 on wave refraction over parallel straight seabed contours, Snell's law states that sin(α) / c = sin(α₀) / c₀. Rearranging yields sin(α) = (c / c₀) · sin(α₀) = (8.20 / 15.60) · sin(45.0°) = 0.52564 · 0.70711 = 0.37168. Therefore, α = arcsin(0.37168) ≈ 21.82° (or 21.8°). As waves enter shallower water, celerity c decreases, causing the wave crests to refract and align nearly parallel to the bathymetric contours.

3According to JTS 145-2015, what is the theoretical maximum wave height to water depth ratio (breaking index γb = Hb / db) for solitary or shallow-water waves on a flat or gently sloping seabed before wave breaking occurs under McCowan's criterion?

A.0.78

B.0.142

C.1.25

D.0.50

Explanation: Per JTS 145-2015 Section 4.4, McCowan's classical wave breaking criterion for solitary and shallow-water waves on gentle slopes establishes that wave breaking occurs when the wave height reaches approximately 78% of the local water depth, i.e., Hb / db ≈ 0.78. In coastal engineering design, this depth-limited breaking index is fundamental for determining maximum design wave heights in shallow surf zones.

4In Chinese port and waterway hydrological design (JTS 145-2015), assuming wave heights in deep to intermediate water follow a standard Rayleigh distribution, what is the theoretical ratio of the 1% cumulative exceedance wave height (H₁%) to the significant wave height (H₁₃%)?

A.1.50

B.1.25

C.1.85

D.1.00

Explanation: Per JTS 145-2015 Section 3.2 on statistical wave height distributions, under the Rayleigh distribution P(H > h) = exp[-A · (h/Hmean)²], the wave height with cumulative exceedance probability p is given by Hp = Hmean · √[ln(1/p) / (π/4)]. Therefore, the ratio of H₁% (p = 0.01) to H₁₃% (p = 0.13) is √[ln(1/0.01) / ln(1/0.13)] = √[ln(100) / ln(7.692)] = √[4.6052 / 2.0402] = √2.2572 ≈ 1.502 ≈ 1.50. In Chinese port design codes, H₁% is approximately 1.40–1.50 times H₁₃% depending on shallow water bottom friction.

5Under JTS 144-1 (Load Code for Harbour Engineering) and the Goda formula, how is the elevation of the maximum wave pressure action line (η*) above the design still water level determined on a vertical wall under non-breaking wave action?

A.η* = 0.75 · (1 + cos β) · λ₁ · HD

B.η* = 0.50 · (1 + sin β) · λ₁ · HD

C.η* = 1.00 · (1 + cos² β) · HD

D.η* = 1.50 · λ₁ · HD

Explanation: Per JTS 144-1-2010 Section 4.2.3 and JTS 145, Goda's formula specifies that the design elevation of wave pressure reaching above the still water level is η* = 0.75 · (1 + cos β) · λ₁ · HD, where β is the angle of wave incidence relative to the wall normal, HD is the design wave height (taken as H₁₃% or H₁% based on structural importance), and λ₁ is a modification factor for structure type (λ₁ = 1.0 for conventional vertical walls).

6According to the Goda wave pressure formula in JTS 144-1-2010, what is the assumed distribution and peak magnitude of wave uplift pressure (pu) acting on the bottom base slab of a caisson breakwater resting on a rubble mound?

A.Triangular distribution with peak pu = 0.5 · (1 + cos β) · αu · γw · HD at the seaside toe, tapering to zero at the portside heel

B.Uniform rectangular distribution with constant pressure pu = γw · HD across the entire caisson base width

C.Trapezoidal distribution with peak pu at the seaside toe and a non-zero residual uplift of 0.5 pu at the portside heel

D.Parabolic distribution with maximum uplift pressure concentrated at the midpoint of the caisson base

Explanation: Per JTS 144-1-2010 Section 4.2.3, the wave-induced uplift pressure acting on the bottom base of a caisson resting on a permeable rubble foundation bed is modeled as a triangular distribution. The maximum uplift pressure pu = 0.5 · (1 + cos β) · αu · γw · HD acts at the seaside toe (where αu is the uplift coefficient) and decreases linearly to zero (0) at the inner rear (portside) heel.

7In the Morison equation for wave forces on slender piles (JTS 144-1), which dimensionless parameter governs the relative magnitude of the drag force (fD) versus the inertia force (fI), and under which condition does inertia force overwhelmingly dominate?

A.Keulegan-Carpenter number KC = umax · T / D; inertia force dominates when KC < 5

B.Reynolds number Re = umax · D / ν; inertia force dominates when Re > 10⁶

C.Froude number Fr = umax / √(g · D); inertia force dominates when Fr > 1.0

D.Strouhal number St = f · D / umax; inertia force dominates when St < 0.2

Explanation: Per JTS 144-1 Section 4.3 and fluid dynamics principles, the Keulegan-Carpenter number KC = umax · T / D (where umax is maximum horizontal water particle velocity, T is wave period, and D is pile diameter) represents the ratio of water particle excursion amplitude to pile diameter. When KC < 5, boundary layer separation and vortex shedding are negligible, making the hydrodynamic drag force negligible and inertia force (fI) overwhelmingly dominant.

8A vertical circular steel pile of diameter D = 1.0 m is driven in a coastal harbor. At an elevation where water density ρ = 1025 kg/m³, the instantaneous horizontal water particle acceleration is ∂u/∂t = 1.50 m/s². Given the inertia coefficient CM = 2.0 per JTS 144-1, calculate the peak wave inertia force per unit length (fI) acting on the pile at this elevation.

A.2.42 kN/m

B.4.83 kN/m

C.1.21 kN/m

D.6.28 kN/m

Explanation: Per JTS 144-1 Section 4.3.2, the Morison inertia force per unit length is fI = CM · ρ · (π · D² / 4) · (∂u/∂t). Substituting the given values: fI = 2.0 · 1025 kg/m³ · (π · (1.0 m)² / 4) · 1.50 m/s² = 2050 · 0.7854 · 1.50 = 2415.1 N/m ≈ 2.42 kN/m.

9According to JTS 144-1-2010, when a large-scale marine cylinder has a diameter-to-wavelength ratio D / L > 0.20, why does the standard Morison equation become invalid, and what theoretical approach must be used?

A.The structure scatters and modifies the incident wave field; wave diffraction theory (e.g., MacCamy-Fuchs formulation) must be applied

B.Turbulent boundary layer separation dominates; empirical Reynolds drag formulas must be applied

C.Dynamic slamming forces occur; Wagner water entry impact theory must be applied

D.Soil-pile interaction becomes non-linear; P-Y curve beam theory must be applied

Explanation: Per JTS 144-1 Section 4.4, when the structural dimension exceeds 20% of the wave length (D / L > 0.20), the cylinder is classified as a large-scale structure. It significantly disturbs, reflects, and diffracts the incoming wave field, violating the slender-body assumption of the Morison equation. Hydrodynamic loads must therefore be calculated using wave diffraction theory (such as the MacCamy-Fuchs analytical solution for circular cylinders or 3D source distribution methods).

10In accordance with JTS 145-2015, how is the Design High Water Level (设计高水位) determined for seaport terminal engineering in coastal areas with regular semidiurnal tides?

A.The water level with an annual cumulative frequency of 90% from the high-water level duration curve (or 4-year cumulative frequency of high tides)

B.The annual maximum tide level with a 50-year return period calculated via Pearson-III distribution

C.The mean sea level (MSL) averaged over a 19-year National Tidal Datum Epoch

D.The highest astronomical tide (HAT) computed from the 11 main tidal harmonic constituents

Explanation: Per JTS 145-2015 Section 2.3, for coastal ports with regular semidiurnal tides, the Design High Water Level (设计高水位) is established based on the high tide level corresponding to a cumulative frequency of 90% from the tide curve (or a 4-year observation period cumulative frequency). It represents the standard operating high water level for berth deck elevation design and quay wall stability under normal operational conditions.
