Read the text and put 3 questions to it:

Rivers carry sediment down their riverbeds, allowing for the formation of depositional features such as river deltas, alluvial fans, braided rivers, oxbow lakes, levees and coastal shores. The construction of a dam blocks the flow of sediment downstream, leading to downstream erosion of these sedimentary depositional environments, and increased sediment build-up in the reservoir.

While the rate of sedimentation varies for each dam and each river, eventually all reservoirs develop a reduced water-storage capacity due to the exchange of "live storage" space for sediment. Diminished storage capacity results in decreased ability to produce hydroelectric power, reduced availability of water for irrigation, and if left unaddressed, may ultimately result in the expiration of the dam and river.

travel broadens the mind- путешествие расширяет кругозор

Travel is the most available and interesting  way to extend your horizon

 Firstly,  Books and the Net give you information,  but you can't get emotions through them. Travelling ensure this opportunity to you. Secondly, Not every source of information is trustworthy and it distorts the reality. However, while you're travelling, you can separate the truth from fakes. Finally, travelling is the easiest way to discover the world, because instead of books it doesn't require high-level thinking skills.

 Thus Travelling will be a convenient way to broaden your mind
