+The module can work only if direction map, streams map and region have the same

 This is checked by default. If resolutions differ, the module informs about 
 it and stops. Region boundary and maps boundary may differ but it may lead 
 to unexpected results. The elevation map is not affected by this restriction 
 and can have whatever resolution.
