An unexpected side effect of the 2010 flooding in parts of Sindh, Pakistan, was the trees cocooned in webs.
It is not clear if the spiders and other insects that created these coccons climbed in the trees to escape the rising flood water, or if the floods produced huge numbers of flies and a feeding frenzy by spiders and insects that led to a population explosion.
The unusual cocoons were a mixed blessing: The huge webs ultimately killed many of the trees they covered, perhaps by reducing the amount of sunlight reaching their leaves. But for a while, the webs also seemed to help trap more mosquitoes in the region, thereby reducing the risk of malaria.

With a very high density of river systems, large parts of Bangladesh remain submerged during five months of monsoon.
A nonprofit initiative has introduced solar-powered floating schools, running a fleet of almost a hundred boats that offer education to kids and their parents, as well as access to libraries, health care, and information about agriculture and financial management.
The Nilometer in Roda Island, Cairo, Egypt - an elaborate version of Roman and ancient Egypt Nilometers - dates back to 715 AD.
The Nilometer measured the water level of the Nile, and depending on the season, predictions to the water levels for the coming season could be issued. The central column is the measuring device, divided and graded into cubits.
An ideal flood filled the Nilometer to the 16 cubit mark; less could mean drought or famine and more could mean a catastrophic flood.
In many ways Egypt was ruled from this spot, it determined so much of Egypt’s economy, tax revenue and ultimately its governance. Because of this special status of this device in Egyptian society and economy, it was the site of one of the medieval world’s most lavish celebrations
In 1910, Paris experienced an extreme flood with water 30 feet above the normal level of the Seine River. It’s expected a flood of this magnitude will occur once every century, so in anticipation of the flood’s 100th anniversary a pseudo-documentary was released describing Paris’ 2011 great flood.
The documentary can be seen on Dailymotion
ARTWORK OF THE WEEK
Two Sisters, 1998
Two Sisters was a 6-metre high, 2.5-metre diameter and 70-ton column of chalk bonded by plaster installed on the silt bed of the Minerva Basin, Hull. The work was continually modified by the tidal flow of the River Humber until it finally eroded and collapsed.

Installed along the North East coastline of Japan, tsunami stones served as warnings and information points indicating the dangers and destruction of tsunamis. Dating back hundreds of years, the stones have since been replaced by more technological warning and defence systems but remain as reminders of the effect tsunamis have had on Japan’s history.

The Resilient Tunnel Project (RTP) is a giant inflatable plug designed to contain flooding or dangerous gases in mass transit tunnels. Developed by the US Department of Homeland Security’s Science and Technology Directorate, the RTP is a 35,000 gallons (about the same capacity as a medium-sized backyard swimming pool) tunnel-shaped plug with rounded capsule-like ends, that can be filled with water or air in minutes to seal off a section of tunnel before flooding gets out of control.
Once a month in Paraty, Brazil, the streets closest to the sea are flooded by the rising tide.
The 19th Century Portuguese engineers deliberately constructed Paraty so that the high tide could enter the streets through openings in the seawalls.
It is said that it was intentionally designed to clean the streets and take the garbage out to sea, but the flooding started after the course of the rivers were altered.
