Transport and communication infrastructure is the backbone of economy to say the least. It has a direct linkage to every sector of economy – the primary sector, secondary sector and tertiary/service sector. An American economist Walt Whitman Rostow in his famous Rostow’s Stages of Economic Growth recognises good transportation infrastructure to be a pre-requisite to take-off. Taking a cue from this, one can perhaps relate as to why the North-east India in general hasn’t been able to tap into the rapid economic growth despite having immense potential – the answer could be poor transportation infrastructure.

So much so that almost three months in one financial year is rendered useless every year. Floods poses a series of challenges to the roadways in Assam. To start with, it is very difficult to construct roads during floods. Floods also damage existing road infrastructure to a large extent. For instance, roads in Assam have a large number of submersible stretches and also a large number of semi-permanent timber bridges. These structures frequently gets damaged during the floods and hamper all weather connectivity in the state.
The presence of numerous rivers in the floodplains necessitates construction of a large number of bridges. The rivers in Assam grow as big as ocean during monsoons and it makes it very difficult for roadways to operate. Many of the bridges are washed away while there are none at many stretches. Coupled to this is the huge pressure on the road network owing to the fact that Assam is the gateway to northeast. Also, of the total rural road network, only around fifty percent are black surfaced roads. Non surfaced roads are almost unusable when there is heavy rainfall.
The roads of a country can be related to the veins and arteries as they allow the connection of the major organs which would be major cities and ports. Without road infrastructure, a country is considered undeveloped and poorly built. The national road, also called the Cumberland road, was a road that stretched from Vandalia, Illinois to Cumberland, Maryland. Vandalia was the capital of Illinois at the time. This road stretching from east to west not only promoted immigration but also connected the markets of the east and west.
There are several things that can result in floods. Rain, obviously, but believe it or not, droughts can, too. A drought is a long period of dry weather, especially one injurious to crops. Droughts can result in floods because during prolonged spells, especially, they will deplete the ground’s source of water, leaving the top layer extraordinarily dry. Then, when it rains, that top layer acts as a natural barrier, preventing the water from soaking in.

The US went through revolutionary advancements in transportation from 1800 to 1840. The transportation improvements had substantial effects on the economy and also individual development. People could now buy goods that were made in places faraway because access was easier to towns and cities and people’s experiences grew as they were able to be more mobile (309). The roads were inadequate in 1800, so the federal government funded the National Road in 1808 to establish its dedication to improve the roads in the nation and so then by 1839 the East and West would be tied together (309). Commerce was still inadequate even with the National Road funded which improved transportation.
The Infrastructure of North Carolina Roads Richard Suggs Western Carolina University Steven Anthony Sciara The Infrastructure of North Carolina Roads North Carolina is one of the fastest growing states in the United States. More than 12.5 million additional people are expected to call North Carolina home by 2040. That is an increase of 32% expected between 2010 and 2040. North Carolina maintains 80,000 miles of roads.
However, the rivers in the Indus valley commonly changed course, more often in times of flooding. This made them unreliable. Rivers
This is due to the river growing larger, as it travels downstream. Most rivers and creeks grow larger as they flow downstream. The difference with the Mississippi is the amount of water being transported through it. The Mississippi has more tributaries than most. What this means for flooding is that it will be increased, the lower you travel.
The building of roads, canals and railroads played a large role in the United States during the 1800s. They served the purpose of connecting towns and settlements so that goods could be transported quickly and more efficiently. These goods could be transported fast, cheap and in safe way through the Erie Canal that was built to connect the Great Lakes to New York. Railroads were important during Civil War as well, because it helped in the transportation of goods, supplies and weapons when necessary. These new forms of transportation shaped the United States into the place that it is today.
As a result, they added important details to the roads to keep them long lasting. Each road was constructed with multiple layers of different types of stone that would hold up under the demand of many people using them. The roads were also designed to remain passable through rain. The roads were equipped with drainage systems that included small ditches throughout the roads and curved surfaces of the roads called cambers that helped the water flow into the ditches and keep the surfaces from flooding (Doc
The water carried the debris through the Sacramento Valley, the Delta, and the San Francisco Bay. Rivers, clogged with sediment, would overflow into the floodplains of the lowland. Floods were destructive for the environment and for residents especially in the Central Valley. Recognizing the importance of managing the water levels, residents along the river attempted to build levees. These levees proved ineffective in solving the flooding problem.
They also include the replacement of undersized structures such as bridges. These works are necessary, as the original channels have become undersized as a result of the increase in flood flows caused by development. Flash flood also can be overcome with storage ponds of flood attenuation. Ponds such as disused mining pools can be used for flood storage. The objective is to divert the flood water through such ponds and thus regulate the outflow so that the flood peaks are attenuated.
When it rains, the water will flow from the hills to the lower area and then stagnant. Eventually the water will increase and flash floods will occur. 2.8.3 River Erosion River
The Elephant and the Dragon by Robyn Meredith highlights China’s and India’s industrial growth and worldwide. Meredith describes China’s and India’s history and how both countries went from being poor to worldwide powers. Meredith shows how each of the country’s leaders influenced the fall of the economy and how future leaders led to the rise of economic growth. In each economy Meredith states that the leaders of both countries found themselves with no choice but to change and she describes the inspiration that both countries deprived their ideas from with lead to great change for the government and the people.
The formation of the main reason is due to flood alluvial. When floods occur, especially in mountainous areas, the following
An introduction to highway building: Although there are many methods to constructing a road, all are based on the principle that geographical objects are removed and replaced with harder and more wear-resistant materials. The pre-existing rock and earth is removed by digging or explosions. Tunnels, embankments and bridge are then added when necessary. The material that the road is being constructed from is then laid by various pieces of equipment, which will be looked at in greater detail in this assignment. The construction management of roads has become increasingly more difficult as larger structures are constantly being required in increasingly short amounts of time.
