Does nonstationarity in rainfall require nonstationary intensity–duration–frequency curves?

Nonstationarity in Intermittent Rainfall: The ‘‘Dry Drift’’

A particular aspect of the nonstationary nature of intermittent rainfall is investigated. It manifests itself in the fact that the average rain rate varies with the distance to the surrounding dry areas. The authors call this fundamental link between the rainfall intensity and the rainfall occurrence process the ‘‘dry drift.’’ Using high-resolution radar rain-rate maps and disdrometer data, the...

Analysis of Recorded Rainfall Information for the Purpose of Huff Curves Extraction in the Dez Dam

Identifying the rainfall characteristics and understanding the rainfall-related processes is one of the key factors in the scientific management of water resources. Selection of the design storm is the first step in the estimation of the design flood. Determining temporal rainfall patterns is very important as one of the design rainfall properties in flood estimation and the design of drainage ...

Does intelligence require a body?

Our brain controls our body—every movement we make is guided by neuronal activity. But how about vice versa? Does the body influence our brain; does it have an impact on how we think? This question might seem odd. We usually stick to a simple ‘sense– think–act’ paradigm: we hear the phone ring (sense), we recognize that we should answer it (think) and grab the receiver (act). This is a one-way ...

Does Privacy Require True Randomness?

Most cryptographic primitives require randomness (for example, to generate their secret keys). Usually, one assumes that perfect randomness is available, but, conceivably, such primitives might be built under weaker, more realistic assumptions. This is known to be true for many authentication applications, when entropy alone is typically sufficient. In contrast, all known techniques for achievi...
