flooding + snow + drought

flood hazard

whether an area is prone to flooding or not

flood risk

potential harms or damage that would result from flooding in an area

exposure

potential casualties due to a communities proximity to a natural hazard

vulnerability

characteristics of a community that affects it ability to cope with a hazardous event

dry metamorphism

as snowpack ages, it metamorphoses due to diffusion of water vapor

crystals pack closer together

wet metamorphism

snow metlsand refreezes, forming denser crystals and affecting the stability of the snowpack.

SWE

amount of water contained in snowpack

snow depth * snow density

dought

deficit of moisture relative to normal conditions for location

aridity

semi permanent climatic feature characterized by low precipitation and high evaporation rates.

5 types of drought

meteorological: dry weather

hydrological: low water supply

agricultural: water shortage damage crops

ecological: lack of soil moisture causes damage

socioeconomic: affect supply/demand of water, food grains, fish
