Floods are a trepidation to anyone living in a lowland. This terror should be an existential concern for anyone to whom the lower end of a reservoir or in the expansive lowlands of the Rift Valley, Nyanza, western and central Kenya and the coastal region as well as the drainage basins and dells of large rivers are home.

Floods have both natural and man-made roots. However, the natural fountainheads may have a human linkage. No disaster can occur naturally without some human sway. This encompasses space disasters. A meteorite impacting the earth’s surface, for instance, may be attributed to disturbance of Space by man — through his valiant space exploits.

FLOODS

Of all the floods in Kenya, rain-begotten floods are the most prevalent. Their genesis is simple: All that is needed is bare land, without trees or grass, and abundance of rain. This is a recipe for immoderate overland flow/surface runoff and murderous floods.

The more intensive the rain falling on a barren or semi-barren land is, the more likely a flood will occur, accompanied by other environmental hazards and disasters such as rockfalls, landslides and disease outbreak.

In the towns and cities, a myriad factors are to blame for the frequent urban floods.
