While travelling for work from Dhaneri (3100) to Marwada (3197) along the metalled road, Sahil crossed over a number of 'causeways'. Why are causeways present in the area shown on the map extract?
Show Hint
Solution and Explanation
The terrain in the area might have areas that are subject to seasonal flooding or waterlogging. A causeway helps in providing a stable route across such areas by elevating the road above the level of surrounding water, ensuring that vehicles and pedestrians can cross without being affected by water.
Step 2: Natural Watercourses.
Causeways are often constructed across natural watercourses, such as streams, small rivers, or seasonal drains, to keep the road accessible year-round. In areas where these watercourses fluctuate with the seasons, causeways provide a means of maintaining road access even during high-water periods.
Step 3: Infrastructural Necessity.
Given the importance of road transport for local movement and connectivity, constructing causeways ensures that transportation infrastructure remains operational during all seasons, preventing the road from being washed out or submerged in the rainy season.
