A backwater curve refers to the rise in water level upstream of a constriction, such as a dam or bridge, due to the obstruction of flow. This phenomenon occurs when the flow of water is impeded, causing the water to back up and create a gradient that affects the hydraulic profile of the river or stream. It is essential for engineers and hydrologists to analyze backwater curves for flood risk assessment and infrastructure design. Understanding these curves helps manage water flow and mitigate potential flooding impacts.

Does a steep learning curve mean learning fast or slowly?
Actually, it has little to do with the learner and more to do with how much there is to be learned. The steeper the learning curve, the more things one has to learn in a shorter amount of time; or the faster the increase in difficulty of the concepts to be mastered. - - - - - Additional: The metaphor "steep learning curve" originally came as a positive reference. A steep learning curve meant that one became quite proficient with a minimum amount of effort/time. It LATER came to be used in the opposite sense - as a negative reference to something difficult to learn (which actually is a shallow, not steep, curve!). A learning curve is shown as a graph of "amount of learning" in the Y axis and the "amount of time or effort" in the X direction. A relatively 'normal' learning curve would be a sloping 's' curve, with its tail starting at the lower left and progressing to the upper right where the head of the s lies. In common (technically incorrect) usage, "steep learning curve" is meant to indicate that to learn the subject/technique takes a long time and is difficult.

What is backwater flooding?
Backwater flooding happens when there is an obstruction downstream that causes the water further upstream to rise over the banks and into the landscape. An ice jam or channel restriction can cause backwater flooding.
