In a certain area of the city, the drains were overflowing and a flood-like situation was created. After a close look at the drains, it was found that the drains were full of plastic bags.
How do you think the plastic bags might have lead to the flood-like situation in the area?
Answers
Cities, utilities, reservoir operators, agriculture, and other industries depend on accurate forecasts of water availability. Hydrologists (water-system scientists) use snow data, river gauges, evaporation rates, precipitation forecasts, radar, and other data to produce forecasts that allow water managers and others to plan efficient and safe use of this natural resource.
Water managers use this information to make decisions about water allocation, such as how much water should be released from a reservoir during spring runoff. These decisions can reduce flooding threats, limit the impact of droughts, and influence fish migrations. Cargo ship and barge captains on large rivers use information on the current and forecasted river level, and flow rate for navigation. Hydroelectric dam operators use similar information to produce electricity efficiently. Fishermen, whitewater paddlers, others who use water recreationally use these river predictions to plan safe outings.
