Hello people in the list,
I am new to R and I am trying to simulate a simple flood model using a digital
elevation model and water height data.
The idea is to find the neighbor pixels of a river and assign to them the
values of the DEM, comparing them with the water height data, and were it
exceeds the height, this pixel is starting to get flooded, the flood continues
to its neighbors taking into account the height from the DEM.
These happens until the water height is again below the DEM.
I need some idea to start, and mainly how to loop inside a SpatialGridDataFrame
or SpatialPixelDataFrame and be able to compare between different
SpatialGridDataFrames in my case DEM and Water Height.
I hope the explanation is clear
Thanks in advance for your help
Best,
Jorge
PD: I am a windows user R version 2.14
