Description: A delta is the deposit of sediment formed at a stream or river mouth, or other location where the slowing of water flow results in sediment deposition. The River Delta Strategy aims to protect and restore freshwater input and tidal flow processes where major river floodplains meet marine waters. These analyses are intended to serve as a durable framework, allowing us to evaluate a proposed action and its ability to restore or protect ecosystem dynamics and services in the context of a site, a sub-basin and the region, providing a powerful basis for planning and prioritization.
