The Nile, for example, is considered to be an arcuate delta because of its arc shaping. As it is waves that shape it into an arc, it also falls under the category of a wave-dominated delta. The word delta is derived from the Greek letter delta, which, like arcuate deltas, is roughly triangular.
Arcuate delta, a type of river delta; Arcuate pocket a type of pocket used in clothing, especially jeans made by Levi Strauss; Arcuate rack, a curved rack gear
This causes erosion on the upstream side of the obstruction and deposition on the downstream side. The deposition that occurs on the downstream side can create a central bar, and an arcuate bar can be formed as flow diverges upstream of the obstruction. [1] Continuous deposition downstream can build up the central bar to form an island ...
The Suez Canal is east of the delta and enters the coastal Lake Manzala in the north-east of the delta. To the north-west are three other coastal lakes or lagoons: Lake Burullus, Lake Idku and Lake Mariout. The Nile is considered to be an "arcuate" delta (arc-shaped), as it resembles a triangle or flower when seen from above.
For example, to calculate the dynamics of a billiard ball being struck, one can approximate the force of the impact by a Dirac delta. In doing so, one not only simplifies the equations, but one also is able to calculate the motion of the ball, by only considering the total impulse of the collision, without a detailed model of all of the elastic ...
The delta potential is the potential = (), where δ(x) is the Dirac delta function. It is called a delta potential well if λ is negative, and a delta potential barrier if λ is positive. The delta has been defined to occur at the origin for simplicity; a shift in the delta function's argument does not change any of the following results.

Simple examples. A simple example of a regular surface is given by the 2-sphere {(x, y, z) | x 2 + y 2 + z 2 = 1}; this surface can be covered by six Monge patches (two of each of the three types given above), taking h(u, v) = ± (1 − u 2 − v 2) 1/2. It can also be covered by two local parametrizations, using stereographic projection.
