This vast, critical reservoir supports a diversity of life and helps regulate Earths climate. One of the models calibration parameters is Mannings Roughness, a friction coefficient based on the topography of the riverbed and floodplain. .table_d2e36 { border-color: #000000; Letting the River Run You may obtain hunting season overnight mooring privileges via a 5-year lease or lottery. Thanks @m_cizek Jul 31, 2014 erod 0. Current conditions of GAGE HEIGHT are available. 2010-23 Atchafalaya National Heritage Area.

You run it for a number of roughness values and when the value matches the satellite height to the model height, you get your calibrated model. About 16,000 acres of subaerial land exist today in the Lower Atchafalaya River and Wax Lake Outlet deltas in Atchafalaya Bay. The Atchafalaya Basin is unique among the basins because it has a growing delta system with nearly stable wetlands.
