The downstream end of a glacier is known as the glacier's terminus or snout, where the ice begins to melt and calve into water bodies or break apart. At this point, the glacier can flow into a body of water, forming icebergs, or it may deposit sediment, contributing to landforms like moraines. The dynamics at the terminus are influenced by climate, with warmer temperatures accelerating melting and retreat. Monitoring these areas is crucial for understanding climate change and its impact on sea-level rise.
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.
Water
Glaciers are the most erosive force in nature due to their ability to transport vast amounts of rock and sediment across the landscape as they move. The immense weight and pressure exerted by glaciers can pluck, scrape, and grind rocks, creating deep valleys, sharp peaks, and U-shaped valleys. Additionally, the meltwater from glaciers can further erode the land by carrying sediment and debris downstream, shaping the landscape over time.
Glaciers or moving, shifting and melting constantly. The worst that could happen is if too meltwater was created by the melting glacier it would cause a flood downstream.
Glaciers can cause significant damage through processes like glacial erosion and flooding. As they move, glaciers can carve out landscapes, erode rock, and transport large debris, reshaping valleys and creating hazards. When glaciers melt rapidly, they can trigger catastrophic flooding, leading to the destruction of infrastructure and ecosystems downstream. The impact of a glacier's movement and melting can be profound, affecting both the environment and human settlements.
glaciers move them downhill and scratch the surface of the valley from a river 'v' to a glacial 'u' they also move lots of rocks. rivers move rocks downstream the higher upstream the more rough and sharp edged they are, downstream they are smoother and rounder due to erosion.

Water
When glaciers melt, you could observe an increase in the volume of water in rivers and lakes downstream. Also, you might notice the retreat or disappearance of the glacier's front edge, leading to changes in the landscape.
The lower parts of glaciers melt and the water flows to fill the rivers downstream. If global warming causes the whole glacier to melt, then the rivers will lose their mountain supply and the lives of people downstream, who rely on water for living and agriculture will be threatened.
Close to the glacier, it will be quite a milky grey colour due to the rock flour. And your system does not tolerate well this contaminant. A little further downstream, it will be drinkable.
Yes, melting glaciers can supply water for people by contributing to the flow of rivers and streams. Glaciers act as important sources of freshwater for downstream communities, especially in regions where they are a primary water source. However, the impact of melting glaciers on water availability can vary depending on factors such as location, season, and rate of melt.

At the end of the last Ice Age, many glaciers began to retreat and melt due to rising global temperatures. This led to the formation of meltwater lakes and contributed to rising sea levels. Some glaciers continue to retreat today due to ongoing climate change.

The last glaciers retreated from Michigan approximately 10,000 years ago at the end of the last glacial period.
Glaciers play a critical role in shaping landscapes by eroding and transporting large amounts of rock and sediment. They also store significant amounts of freshwater in the form of ice, which contributes to sea level regulation and supports ecosystems downstream. Additionally, glaciers are important indicators of climate change, as their melting rates can provide insights into environmental conditions.
