Alexandria is a major city in Egypt. Lying at the western edge of the Nile River Delta, it extends about 40 km (25 mi) along the country's northern coast. It is Egypt's principal seaport, the second largest city after Cairo, and the largest city on the Mediterranean coast. Founded in 331 BC by Alexander the Great, Alexandria is one of the largest and most important cities of antiquity and a leading hub for science, culture, and scholarship.

Nicknamed the "Bride of the Mediterranean" and "Pearl of the Mediterranean Coast", the city is a popular tourist destination and a major industrial centre. It is the sixth-largest city in the Arab world and in the Middle East, and the eleventh-largest city and urban area in Africa. Alexandria was established originally near an ancient Egyptian settlement named Rhacotis, which later became its Egyptian quarter. The city was made the capital of the Ptolemaic Kingdom and became the foremost commercial, intellectual, and cultural centre for much of the Hellenistic age and late antiquity; at one time, it was the most populous city in the ancient world. Alexandria was best known for the Lighthouse of Alexandria (Pharos), one of the Seven Wonders of the Ancient World; its Great Library, the largest in the ancient world; and the Catacombs of Kom El Shoqafa, one of the Seven Wonders of the Middle Ages.

An island country, island state, or island nation is a country whose primary territory consists of one or more islands or parts of islands. Approximately 25% of all independent countries are island countries. Island countries are historically more stable than many continental states but are vulnerable to conquest by naval superpowers. Indonesia is the largest and most populated island country in the world (and the fourth most populated country overall).

There are great variations between island country economies: they may rely mainly on extractive industries, such as mining, fishing and agriculture, and/or on services such as transit hubs, tourism, and financial services. Many islands have low-lying geographies and their economies and population centers develop along coast plains and ports; such states may be vulnerable to the effects of climate change, especially sea level rise.

Borders are generally defined as geographical boundaries, imposed either by features such as oceans and terrain, or by political entities such as governments, sovereign states, federated states, and other subnational entities. Political borders can be established through warfare, colonization, or mutual agreements between the political entities that reside in those areas.

Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded. Most external political borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints; adjacent border zones may also be controlled. For the purposes of border control, airports and seaports are also classed as borders. Most countries have some form of border control to regulate or limit the movement of people, animals, and goods into and out of the country. Under international law, each country is generally permitted to legislate the conditions that have to be met in order to cross its borders, and to prevent people from crossing its borders in violation of those laws.

Public works are a broad category of infrastructure projects, financed and procured by a government body for recreational, employment, and health and safety uses in the greater community. They include public buildings (municipal buildings, schools, and hospitals), transport infrastructure (roads, railroads, bridges, pipelines, canals, ports, and airports), public spaces (public squares, parks, and beaches), public services (water supply and treatment, sewage treatment, electrical grid, and dams), environmental protection (drinking water protection, soil erosion reduction,wildlife habitat preservation, preservation and restoration of forests and wetlands) and other, usually long-term, physical assets and facilities. Though often interchangeable with public infrastructure and public capital, public works does not necessarily carry an economic component, thereby being a broader term. Construction may be undertaken either by directly employed labour or by a private operator.

Public works has been encouraged since antiquity. The Roman emperor Nero encouraged the construction of various infrastructure projects during widespread deflation.

During the era of the Roman Empire, most of modern-day Egypt except for the Sinai was ruled as the imperial province of Aegyptus, from the time it was conquered by Roman forces in 27 BC, to AD 642. The province was bordered by Crete and Cyrenaica to the west and Judaea, later Arabia Petraea, to the East.

Egypt came to serve as a major producer of grain for the empire and had a highly developed urban economy. It was by far the wealthiest Roman province outside of Italy. The population of Roman Egypt is unknown, although estimates vary from 4 to 8 million. Alexandria, its capital, was the largest port and second largest city of the Roman Empire.

A border checkpoint is a location on an international border where travelers or goods are inspected and allowed (or denied) passage through. Authorization often is required to enter a country through its borders. Access-controlled borders often have a limited number of checkpoints where they can be crossed without legal sanctions. Arrangements or treaties may be formed to allow or mandate less restrained crossings (e.g. the Schengen Agreement). Land border checkpoints (land ports of entry) can be contrasted with the customs and immigration facilities at seaports, international airports, and other ports of entry.

Gulf of Burgas or Burgas Bay (Bulgarian: Бургаски залив, Burgaski zaliv) between the coastline and the straight line joining Cape Emine and Cape Maslen nos is the largest bay of the Bulgarian Black Sea Coast and one of the largest in the Black Sea. The length of the gulf is 44 kilometres. It is 41 km at its widest and 25 m at its deepest, reaching 31 km at its greatest innermost extent, approximately where the Bulgarian city and major port of Burgas is located. Other towns in the region include Pomorie, Sozopol and Nesebar. The Burgas Bay is the Black Sea's westernmost point.

The bay gets narrow to the west. While the northern coast is lower and has two big peninsulas, at Nesebar and Pomorie, the southern part of the bay is rougher, with many little inlets and headlands. The water's salinity in the bay is 17‰; the sand is of magnetite origin. The Burgas Lakes are located in the wetlands to the west.

29°58′N 32°33′E / 29.967°N 32.550°E / 29.967; 32.550Railway lines and highways connect the city with Cairo, Port Said, and Ismailia. Suez has a petrochemical plant, and its oil refineries have pipelines carrying the finished product to Cairo. These are represented in the flag of the governorate: the blue background refers to the sea, the gear refers to Suez's status as an industrial governorate, and the flame refers to the petroleum firms of Suez. The city has three ports: the Suez Port (Port Tewfik), al-Adabiya, and al-Zaytiya, and extensive port facilities. Together, the three cities form the Suez metropolitan area, located mostly in Africa with a small portion in Asia.

Hinterland is a German word meaning either the 'land of men' or the 'land behind' a city, a port, or similar. Its use in English was first documented by the geographer George Chisholm in his Handbook of Commercial Geography (1888). Originally the term was associated with the area of a port in which materials for export and import are stored and shipped. Subsequently, the use of the word expanded to include any area under the influence of a particular human settlement.

In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While channel typically refers to a natural formation, the cognate term canal denotes a similar artificial structure.

Channels are important for the functionality of ports and other bodies of water used for navigability for shipping. Naturally, channels will change their depth and capacity due to erosion and deposition processes. Humans maintain navigable channels by dredging and other engineering processes.

Sevastopol Marine Trade Port (SMTP) is a port in Sevastopol. It is located mainly at the Bay of Sevastopol, and at smaller bays around the Heracles peninsula. The port infrastructure is fully integrated with the city of Sevastopol and naval bases of the Russian Navy and the Black Sea Fleet.

The port had previously been under the sovereignty of Ukraine following the dissolution of the Soviet Union in 1991 and a formal partition treaty was signed by Ukraine and Russia in 1997. Portions of the port were owned by the private sector.. The port came under full Russian control when Russia occupied the Crimean peninsula in early 2014 after a highly criticized referendum known as the 2014 Crimean status referendum.

Novorossiysk Sea Port (Russian: Новороссийский морской порт, NSP) is one of the largest ports in the Black Sea basin and the largest in Krasnodar Krai. At 8.3 km, the NSP berthing line is the longest among all the ports of Russia. The port is located on the Northeast coast of the Black Sea, in the Tsemes Bay (also called Novorossiysk Bay). The bay is ice-free and open for navigation all year round. However, in winter the navigation occasionally stops due to the hazardous northeastern bora wind. The Tsemes Bay allows deep-draft vessels up to 19 m, and the inner harbour up to 12.5 m. The liquid bulk terminals depth range from 8.4 to 15.6 m, suitable for tankers with a deadweight of up to 250,000 tons, like Suezmax-class vessels.
