Explanation:
cost
- ongoing maintenance
- initial design and construction
benefit
- protection of infrastructure
- lower insurance costs
- employment opportunities
The flood mitigation projects have initial startup costs and ongoing maintenance costs over the years. However, apart from the costs, these have additional benefits like lower insurance costs due to protected infrastructure and reduced flood damage, along with employment opportunities during building and maintenance.
Further Explanation:
Flooding usually happens when lots of rainfall occurs in relatively short time periods. These are usually enough to cause rivers to overflow their banks and also occur when storms force large volumes of water from the ocean to travel inland. Typically these occur in arid ecosystems, having low average rainfall- the water accumulates in dry regions and saturates the area. This phenomena are majorly destructive and can uproot trees, destroy bridges, buildings and other infrastructure while leading to loss of life.

Answer:
Wolves can also increase tourism.... Wolves were introduced for habitat conservation at Coronation Island, Alaska in 1960, and there they successfully managed deer before the wolf population expanded and then crashed.
Layers of cross-bedded sand can be indicative of a DESERT environment wind is responsible for the formation of these sedimentary structures. Sand dunes preserved in rocks can be quite large. These structures form as a result of the migration of dunes due to the action of the wind. Dunes are not often preserved but a few can be observed in thick sandstone units.
