EGU2009 第三天會議行程-2

EGU2009-13415

D. Yu and S.N. Lane

Interactions between sub grid-scale resolution, feature representation
and grid-scale resolution in flood inundation modelling

Flood risk
FRMRC
RIVER Eden river risk mapping

資料中存在著 uncertainty
雨量轉換為水位的過程中也存在著不確定性

10GPRS level sensors

EGU2009-3764

R. Moussa, J. Ghesqui?re, and D. Hallema

On the use of the diffusive wave for modelling extreme flood events
with overbank flow in the floodplain

使用1D進行模擬

2540 km 集水區

利用洪水痕(FLOOD MARK)

DEM cell : 1 ~100 sqKM
使用歷史事件模擬
使用斷面資料

小集水區
pipes :11KM
236channels

MHYDAS model
ditch in a floodplain

EGU2009-1437
G. Schumann, G. Di Baldassarre, L. M. Stephens, and P. D. Bates等
Augmenting the direct use of remote sensing in flood management

使用SAR :
Dry soil Wet soil Urban

idea : SAR 適合大區域

uncertainty in mapping flood
SAR 12.5m
ENVISAT-ASAR 75M

利用兩種影像進行比對
資料間的差異性 VIS

Flood frequency estimation by hydrological continuous simulation and
classical methods

Design storm Method
CRRM continuous raunfall runoff method
Soil water balance model
event based raunfall runoff method


EGU2009-11719
H. Zwenzner
Improved mapping of flood extent and flood depth using space based
SAR data in combination with very high resolution digital elevation
data

WAQUA MODEL 2d
Model uncertainty
在資料輸入 模式計算 等
Quantification of uncertainty
Different MODEL Purposes have different uncertainties ,which is often forgotten

QGIS Raster to Vector use Python console step2

資料處理步驟: 1.讀取 Raster 並計算 25 等級等值線級距 2.用 GDAL 產生等值線(Contour Lines) 3.Polygonize:Raster 轉等值面多邊形 4.將多邊形圖層載入 QGIS 5.為每個 polygon 計算其 VALUE 所屬級距(LE...
