In 3–5 sentences, describe flood mitigation techniques the federal government might use.

Several flood mitigation techniques can be used by federal governments.

Explanation:

Diversion of flood water and its storage is a method that can be used for flood mitigation. Floodwaters can be diverted to canals, reservoirs, floodplains etc.

Thus water can be kept out of inhabited areas. Federal governments can enact legislation to establish floodwater and storage.  Restoration of streams and floodplains is another method that can be used to mitigate floods.

These methods can prevent bank erosion and reduce the severity of floods. Legislation's regarding the restoration can be passed by federal states.

Low impact development and green infrastructure store water and thus helps preventing floods. This is another method to mitigate floods.  

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
