MAP BASE LEGEND Topography: ASTER digital elevation model and topographic base maps of scales 1:5,000 and 1:10,000 prepared by the Scale 1 : 50,000 TROPICAL CYCLONINDUCED STORM SURGE Main Road EEE Province Boundary Department of Survey, Sri Lanka. 20 10 0 20 40 60 80 100 HAZARD MAP - SHEET 03 Bathymetry: GEBCO data of 30 arc-second resolution supplemented with data from nautical charts. Minor Road EEEE District Boundary Other Roads Kilometre MAP INFORMATION LIMITATIONS µ D.S.Div. Boundary Railway One limitation is that the resolution of the numerical computations is no greater or more accurate than the bathymetric and Balangoda Village Name Origin of the grid system is 200,000 metres South and 200,000 metres West of Pidurutalagala. METHOD OF PREPARATION topographic data used. The resolution of the model also constrains its ability to resolve some small-scale features of the onshore LOCATION Storm surge inundation shown on the map is based on a static projection of storm surge levels near the shoreline derived from a terrain including narrow waterways, lakes and interiors of lagoons and no warranties are made regarding the accuracy of the map Bridge / River / Stream / Canal NAGODA D.S.Div. Name computer model of tropical cyclone induced forcing on the sea-surface. The simulated storm surge corresponds to a probable nor the data from which the map was derived. The present hazard analysis is essentially deterministic, and therefore, this map Strom Surge Map (Wind Speed 270 km/h) 10 Bathymetrical Contour / Value cyclone of maximum wind speed 270 km/h originating in the Bay of Bengal. The mean recurrence interval for this cyclone scenario includes no information about the probability of any cyclone generated storm surge affecting any area within a specific period of Tank Published by is expected to be of the order of 300 years. Given the considerable uncertainty on the probable track of the cyclone including its time. The non-linear interaction of the tide and surge is not included in the numerical simulations; however, a conservative location of landfall, storm surge simulations were carried out for a large set of synthetic tracks that are in statistical agreement with 01 Index Contour superposition of the high tide has been incorporated in keeping with the purpose of hazard mapping. While this storm surge hazard Temple the historical database in order to derive a composite of the maxima of surge levels. The model used is MIKE21-HD of the Danish 02 Coastal Research and Design, map has been compiled with the best currently available scientific information and base data, users are invited to notify JAFFNA 20 Intermediate Contour/ Value Hydraulic Institute (DHI), which solves the vertically integrated, non-linear equations of conservation of mass and momentum using CCCRMD/DMC of any map discrepancies.
