River delta slope offshore, waves will make river deltas smoother. Waves can also be responsible for carrying sediments away from the river delta, causing the delta to retreat. For deltas that form further upriver in an estuary, there are complex yet quantifiable linkages between winds, tides, river discharge, and delta water levels. Erosion is also an important control in tide-dominated deltas, such as the Ganges Delta, which may be mainly submarine, with prominent sandbars and ridges. This tends to produce a "dendritic" structure. Tidal deltas behave differently from a river- and wave-dominated deltas, which tend to have a few main distributaries. Once
Delta Meadows River Park Delta Meadows River Park Delta Meadows River Park (DMRP) is a state park property of California, USA, preserving an undeveloped piece of the Sacramento–San Joaquin River Delta. At present it is officially closed to the public and has no visitor services. The park encompasses sloughs, wet meadows, and an island between the Sacramento and Mokelumne Rivers. It is located near the historic Chinese American town of Locke, equidistant from Sacramento and Stockton. The property was established in 1985. Delta Meadows preserves a river delta much as it appeared 150 years ago, crowded with stands of oak, tule, walnut, willow, and
