Possible Roles of Artificial Neural Networks in Hydraulic and Hydrological Models

This paper presents 2 past and 1 on-going works on the applications of Artificial Neural Networks (ANN). The 2 past works are river flow forecasting in Bangladesh (a country with vast delta and severe floods perennially) and forecasting of maximum wave height and its time of arrival of the devastating Aceh tsunami in 2004. The on-going work is on deriving a cost effective and high accuracy Digital Elevation Model (DEM) from publicly accessible satellite data.
