Suitability of Water Harvesting in the Upper Blue Nile Basin, Ethiopia: A First Step towards a Mesoscale Hydrological Modeling Framework

Table 5

The suitability levels for water harvesting of the total basin area (in percent) according to different weight combinations of influencing variables: suitability levels 1-2: low suitability, suitability level 3: moderate suitability, and suitability levels 4-5: high suitability.

Suitability level	Condition 1	Condition 2	Condition 3	Condition 4	Condition 5
5	0.00	0.00	0.00	0.00	0.00
4	23.68	11.92	8.26	10.15	6.49
3	57.72	61.41	61.21	62.99	61.55
2	16.43	23.50	28.34	23.71	29.75
1	0.00	0.97	0.00	0.97	0.00

Note: condition 1 is with equal weighting among all factors; condition 2 places highest weight on rainfall and slope; condition 3 has highest weight assigned to rainfall; condition 4 has highest weight assigned to slope;  and  condition 5 differentiates among all four factors, with rainfall being the most important.
