Since we have no idea what "this" might be, we can't answer the question properly.
If mountain glaciers disappear there will be no source for many mountain streams, which will then dry up. Many rivers will be reduced in size as a result.
From streams and rivers, rain puddles

Mountain streams and rivers of the eastern states.
How could each of these changes affect erosión and streams
Rivers and streams are the genesis of life in an ecosystem. Without these rivers and streams, the chain of life cannot be extended. All human and animal life and their derivatives depend on these bodies of water.
They reduce flow, and create a backpool which reduces flow downstream
Water is from snow packs, rivers, lakes, ponds, and streams.
Usually at the top of mountains, they start off as streams. Then the streams join together and get bigger, wider, and eventually they turn into rivers.
Clear mountain rivers and streams, mainly in the higher mountains.
Rivers in the Himalayas originate primarily from the melting of glaciers and snow in the mountain ranges. As temperatures rise, glacial meltwater flows down the slopes, forming streams and tributaries. Additionally, heavy monsoon rains contribute to river formation by increasing water flow from the mountains. These rivers often carve deep valleys and canyons as they journey downstream.
Streams and rivers cause erosion by carrying sediment and rocks downstream, gradually wearing down the land over time. When the velocity of the water decreases, sediments are deposited along the riverbanks and the riverbed, leading to the formation of riverbanks and floodplains.
