Tidal Estuaries: Forecasting by Model Experiments*

Rías and Tidal-sea Estuaries

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Asymptotic behavior of tidal damping in alluvial estuaries

[1] Tidal wave propagation can be described analytically by a set of four implicit equations, i.e., the phase lag equation, the scaling equation, the damping equation, and the celerity equation. It is demonstrated that this system of equations has an asymptotic solution for an infinite channel, reflecting the balance between friction and channel convergence. Subsequently, explicit expressions f...

Forecasting Experiments Using the Regional Meteorological Model and the Numerical Snow Cover Model in the Snow Disaster Forecasting System

The Snow and Ice Research Center (SIRC) of the National Research Institute for Earth Science and Disaster Prevention (NIED) of Japan has been developing a snow disaster forecasting system. This system consists of an atmospheric mesoscale model NHM, the numerical snow cover model SNOWPACK, and three diagnostic models of snow disasters. In this paper, the performance of NHM and SNOWPACK is invest...

Tidal Flow Forecasting using Reduced Rank Square Root Filters

A selection of these reports is available in PostScript form at the Faculty's anonymous ftp-Abstract The Kalman lter algorithm can be used for many data assimilation problems. For large systems, that arise from discretizing partial diierential equations, the standard algorithm has huge computational and storage requirements. This makes direct use infeasible for many applications. In addition nu...
