No, a flood can not be destructive and constructive, but it can be destructive.I think Egyptians would disagree. The country of Egypt flourished for millennia because the annual flooding of the Nile deposited fertile soil on top of the Saharan sand.A small flood, like a river one, will only damage basements. Things stored there will get wet and waterlogged, the floors will get really really yucky. Big things like tsunamis make people drown and destroy houses.
An increase in gradient will generally increase stream velocity.
The jet stream
Stream terraces and incised meanders
All streams meander to some extent. The most likely time is when flow is consistent and gradient is uniform. See Braided Stream. When a stream has eroded the steep valleys to genteler slopes, the stream flows more slowly.Now water in the stream erodes along the sides of the stream bed rather than along the stream bottom. === ===

Once a cave passage is abandoned by its formative stream, it can become: - Choked with sediments deposited by the dying floods of that stream or brought in by glacial thaw (Gaping Gill, in NW England, holds vast quantities of glacial till out of erosive reach of the present stream). - Richly decorated with stalagmites and stalactites (these won't grow under water). - Filled with boulders falling from roof and walls as ground-water seeping through the joints in thelimestone above it, dissolves the rock enough to weaken the structure: a destructive rather than constructive act of the same process that initiated the cave.
A mature stream.
A gulf stream is water ,and a jet stream is air.
A stream bed is the bottom (floor) of the stream.
Art stream
The stream reach is the length of the stream you have selected for monitoring.
The Limpid Stream was created in 1935.
It is occasionally called a sinking stream or a disappearing stream, but geographers and geologists normally call it a stream, just like another stream.
Lowering a stream's base level will cause the stream to do what?
The mouth of a stream is where the stream flows out into a larger body of water.
an old stream is a deep wide and curvy river stream
