What is the main topography of the Rhone River basin? What is terrain?

Both the Rhone River and the Alvo River originate from the Alps, but the high temperature in summer and the melting of snow in alpine glaciers lead to large river runoff. Due to mountainous terrain, undulating terrain, rapid water flow and strong scouring, the river has a large sediment concentration. However, there is a lake in the upper reaches of the Rhone River at the intersection of the two rivers, so the sediment carried from the upper reaches of the Rhone River is deposited in the lake, which leads to the decrease of sediment concentration after the Rhone River leaves the lake. This river is relatively clear. The sediment carried by the Alvo River flows from upstream to downstream, and the river is turbid. Therefore, at the intersection of the Rhone River and the Alvo River, the water of the Rhone River is relatively clear, while the water of the Alvo River is relatively turbid, resulting in a distinct phenomenon.

(2) Reading the map, we can see that the Rhone River flows into Lake Geneva. For Lake Geneva, the injection of the Rhone River provides water for Lake Geneva. The main disadvantage is that the Rhone River enters the river course, and it also brings sediment deposition, which leads to the high riverbed and reduces the storage function of the lake. The water in Lake Geneva is discharged through the Rhone River downstream.

(3) The topography of the Rhone River Basin is mainly mountainous, with large relief, large river drop, fast flow rate and abundant water resources, which is suitable for dam building, hydropower development and rafting. The basin has beautiful environment, beautiful scenery and charming scenery, which can develop tourism.

So the answer is:

(1) Summer. Reasons: The sediment transported from the upper reaches of the Rhone River is deposited in the lake, which greatly reduces the sediment content when the river leaves the lake and makes the river clear; The source of the Alvo River comes from the Alps. In summer, the amount of ice and snow melting is large and the runoff is large. Due to the great difference in topography, the rapid flow and strong scouring, the river has a large sediment concentration and the river is turbid.

(2) The Rhone River is the main recharge source of Lake Geneva; Sediments deposited in the lake raised the lake bed, which is also the downward passage of Lake Geneva.

(3) Power generation and drifting (tourism). Switzerland is mainly mountainous, with large river drop, large flow, rapid water flow and abundant hydropower resources, which is suitable for hydropower development; The beautiful scenery in China is attractive to tourists.
