A landslide is a very localised event, it will have little direct effect on the greater environment. Locally a landslide can cause a lot of damage. If it is big enough and gains enough speed it can envelope and flatten anything that stands in its way, from houses to forestland. If it were to end in a river or stream I suppose it would lead to raised water levels, but flooding is not a common result of landslides (to the best of my knowledge). Landslides occur when a piece of ground becomes unstable and is on a gradient. If it is gorged with water this can become a massive slide of mud pouring down the hillside. If it is dry this does not mean it will flow any slower, there are sites where it can be shown that landslides flowed down one side of the valley and back up the other side....granted I don't think that happens too often though.

When landslides occur, the soil will flow into the rivers and lakes. This causes the water level to rise. Floods would occur.
