I am trying to measure the effectiveness of flood mitigation in a river using ArcGIS 10.2. Data available to me are the left and right bank polyline of 4 years , settlement data and point data where the mitigation is applied. We have applied river mitigation measures at the end of first year so that its effect is seen at the end of 2nd, 3rd and 4th year.(Like the shift of river, change in the area of river and effect on the settlements near the banks of river).
Is there any way I can measure the effectiveness of the mitigation applied using ArcGIS Desktop tools?
