Have you ever wondered what the numerology of the name Deltha is? Did you know that the name is a combination of several alphabet numbers? In numerology, every letter of the name represents a certain number. For example, the name Deltha possesses the number five as its destiny number. The meaning of this number is "good fortune."
The delta develops from the accumulation of sediments, which are called forests. These sediments are larger and more variable than the bottom set beds. They form the bed load of a delta, which rolls over its front. Typically, foreset beds occur in parallel bands and indicate different stages of delta formation. The angle of repose of forests determines the outer edge of a delta. This process has occurred in seven deltas on the Mississippi River over the last 5,000 years.
A tide-dominated delta is an estuary with an end-member system. Its width is determined by the tidal discharge at the mouth of the river. The number T is strongly related to the Canter-Cremers estuary number (CCR), which measures the ratio of freshwater discharge to saline water discharge. This type of delta is also known as a tidal bay.
Recent studies have shown that the morphometry of modern wave-dominated deltas is relatively symmetric. Fanos et al. examined the promontories of the Nile River Delta, while Jimenez et al. studied the lobes of the Ebro River Delta. Bortoluzzi et al. studied the Tiber River Delta. Despite this symmetrical nature, wave-dominated deltas can be quite complex.
Sediment transport processes are important for determining the formation and evolution of the Gilbert delta. A tilting flume constructed in the Water Laboratory of the Delft University of Technology measures 14.4 meters, 40 cm wide, and 45 cm high. The flume contains a flow regulation device and a weir at the downstream end. An in-house-built sediment feeder supplies the flume with sediments. In this study, sediment transport processes were modeled using a numerical model developed by Blom and Kleinhans (2006).
An estuarine delta is a coastal inlet formed by natural processes, such as river discharge, sediment inflow, and tides. It is different from a river delta, which is dominated by sediment dynamics constrained by geology. Most coasts have gently sloping coastal plains. However, some coastal systems exhibit the same morphological features and processes. In these cases, the watershed may be considered an estuarine delta.
