As soon as a tsunami approaches the coast, its speed decreases considerably. This is because the speed of a tsunami depends on the depth of the water; the lesser the depth of the water, the lesser the speed of an approaching tsunami. However, there is no change in the overall impact of a tsunami.
Water stress refers to economic, social, or environmental problems caused by unmet water needs. Lack of supply is often caused by contamination, drought, or a disruption in distribution. In an extreme example, when Côte D’Ivoire split four years ago between the rebel-led north and government-ruled south, the conflict led to unpaid water bills, which precipitated a dangerous health threat in the region, increasing the risk of water-born diseases such as cholera. Some analysts believe the disruption of distribution was a political ploy to put pressure on the rebel-led north.

Answer:
Drought is a condition, not a hypothesis. Drought is the lack of rain, or evaporation in excess of precipitation.
The CAUSE of drought is a multi-pronged hypothesis. It can be due to cyclic changes in ocean temperature (El Niño/La Niña). It can be due to rain shadow downwind of a mountain range. It can be due to fluctuations in the sun’s brightness. It can be the result of urban sprawl and resulting shifts in upwind evaporation/transpiration. It can be the result of climate bands shifting in response to changing atmospheric composition. It can be the result of agricultural practices upwind. It can be just bad luck, with a location consistently not being the whatever-percent chance of where it’s raining.
