澳門為何建不到深水港？
Feng Shui Analysis of Building a Deep-Water Port in Macau
It is widely recognized that Macau suffers from inherent geographical disadvantages—its waterways are simply too shallow to accommodate a deep-water port. From a commercial and economic standpoint, water depth has always been the critical bottleneck constraining Macau’s takeoff. Today, Mickey Hung combines Macau’s unique feng shui and geographic setting to examine the conditions for constructing a deep-water port in the territory.
I. Feng Shui Layout
From the perspective of traditional geographic feng shui, Macau sits on the western bank of the Pearl River estuary, with a classic “mountains embracing and waters encircling” topography.
• Water mouth and qi accumulation: The three islands—the Macau Peninsula, Taipa, and Coloane—are scattered like pearls, occupying a pivotal position at the Pearl River outlet. The currents from Modaomen and Lingdingyang converge here, forming a “crisscross” pattern. Feng shui holds that “water follows the mountains, and qi follows the water.” As a zone where the Pearl River runoff and ocean tides contend, Macau is a natural “qi-gathering” place.
• Geographic advantage of Ka-Hó Village: Coloane’s Ka-Hó Container Terminal, located at Datan Point, is backed by hills and faces the open sea. In feng shui terms, this represents a stable “backed by mountains, facing water” configuration. Unlike the Inner Harbour and the Outer Harbour, which are constrained by shoals and siltation, the Ka-Hó Container Terminal possesses a natural aura that “breathes in the ocean’s energy,” making it a vibrant site for Macau’s new growth momentum.
II. Topographic Conditions
The surrounding topography poses natural challenges to deep-water port development, but solutions do exist.
1. Natural depth limitations
Macau lies on the western side of the Pearl River estuary, precisely in the main area where riverine sediment spreads and deposits. As the current slows here and is further obstructed by tidal backwater, massive sedimentation occurs, resulting in significant siltation around Macau’s waters. Port depths generally range only from 3 to 5 metres. Even the Ka-Hó Container Terminal, built after attempts to create a deep-water facility, reaches only 7–9 metres and faces annual siltation of 38–50 centimetres, with extremely high maintenance costs.
• Inner Harbour and Outer Harbour: Water depths are only 3–4.5 metres, maintained mainly through frequent dredging, and can only accommodate vessels of around 1,000 tonnes—far from sufficient for modern ocean-going shipping.
• Shizimen: Although certain local deep grooves reach 7 metres in depth, the strong back-siltation caused by sediment transport from the Maliuzhou waterway makes it an undesirable deep-water site.
2. The “geographic advantage” of Ka-Hó Container Terminal
The Ka-Hó Container Terminal is widely regarded as the best port site in Macau—and even in the western part of Lingdingyang.
• High dredging efficiency: The dredging volume required for a 10,000 tonne channel is only one-third of that for the Outer Harbour and one-quarter of that for the Inner Harbour.
• Controllable siltation: The rate of back-siltation is far lower than at the Outer Harbour. Studies indicate that once throughput reaches a certain scale, the economic returns are sufficient to cover dredging costs, effectively breaking the “shallow-water constraint.”
III. Hydrological Conditions
In the Northern Hemisphere, because water flow consistently deflects to the right, two distinct types of riverbanks emerge:
• Right bank (erosional bank): The current continuously scours the right bank, causing bank collapse and deepening of the riverbed. Thus, the right bank tends to have deeper water and steeper slopes, providing natural conditions for a deep-water port.
• Left bank (depositional bank): The current carries eroded sediment to the left bank, where it settles. Hence, the left bank is typically shallow, gently sloping, and prone to siltation—unsuitable for a deep-water port.
Note:
The main stem of the Pearl River (the Xijiang) flows from northwest to southeast into Lingdingyang and the South China Sea. The direction of flow is northwest → southeast.
Standing at the Modaomen outlet, facing southeast (toward the sea):
• On your left-hand side (geographic west): Macau and Zhuhai—the left bank of the Pearl River system, i.e., the depositional bank.
• On your right-hand side (geographic east): Hong Kong and Shenzhen—the right bank of the Pearl River system, i.e., the erosional bank.
Applying the Coriolis effect (Northern Hemisphere currents deflect rightward):
The river flows southeastward and deflects to the right (east), so the water force hits the eastern shore (Hong Kong and Shenzhen), continuously eroding and deepening it. The sediment is separated and deposited on the western shore (Macau and Zhuhai). This perfectly matches the theory:
• Right bank (eastern shore – Hong Kong/Shenzhen): erosion, deep water, natural good harbour.
• Left bank (western shore – Macau/Zhuhai): deposition, shoals, persistent siltation.
IV. Comparative Waterway Advantages: Macau vs. Hong Kong
From a feng shui perspective, Macau lies on the western side of the Pearl River estuary. The Earth’s rotation generates the Coriolis force, which deflects Northern Hemisphere currents to the right. Since the Pearl River’s main flow moves northwest to southeast into the sea, the rightward deflection shifts the current toward the west (the Macau side). This western side receives about 95% of the river’s sediment load, which, combined with lateral circulation, causes continuous sediment deposition near Macau’s coast. As a result, extensive shoals and a westward‐biased sandbar have formed, leaving natural water depths severely inadequate—making the site unsuitable for a large deep-water hub port.
Hong Kong (eastern side of the Pearl River estuary):
Hong Kong is located on the eastern side (right bank) of the estuary. Although the right bank is theoretically erosional, Hong Kong’s uniqueness lies in:
1. Geological advantage: Victoria Harbour itself is a rock‐flooded valley, with a solid bedrock foundation that resists siltation.
2. Strong hydrodynamics: The sea areas around Hong Kong experience powerful currents that effectively carry away sediment.
Thus, even though it sits on the “theoretically depositional” side, Hong Kong—thanks to its exceptional geological conditions and marine dynamics—has naturally become an excellent deep-water harbour.
V. Feng Shui Recommendations
For the development of a deep-water port in Macau, the following recommendations are proposed:
• Integrated planning and multi-purpose works: Combine deep-water port construction with land reclamation and airport projects. Employ artificial measures (e.g., silt intercepting dikes) to reduce back siltation, achieving multiple benefits such as wave protection, sediment control, and land utilisation.
• Strengthen inland waterway connectivity: Resolve the “bottleneck” at the Hongwan section of the Maliuzhou waterway, opening up the vital link between Macau and the Pearl River’s inland navigation network, thereby extending the port’s hinterland deep into the Pearl River basin.
• Differentiated competition: Rather than competing head on with Hong Kong or Gaolan Port, Macau should leverage its free port advantages to develop dedicated deep sea routes (e.g., to Europe), positioning itself as an international hub within the Pearl River Delta port cluster.
