| Factor | Order of Importance | Argument |
| Slope | 1 | Slope influences dam safety since higher slopes have more risks of landslides and usually give pressure to the foundation of the dam [10] |
| Geology | 2 | The rock type within a certain region influences permeability of the dam [25] which includes the capability of holding water for the dam |
| Soil type | 3 | Different soil types have different infiltration rate which usually influence the runoff flowing to the dam [29] |
| Catchment Size | 4 | A Large catchment will provide sufficient water for the dam [30] |
| Land Cover | 5 | This is useful for examination of land that have different economical cost depending on the land cover type and at the same time land cover influences soil erosion which usually creates a weak foundation for constructing a dam [10] |
| Proximity to River | 6 | A suitable dam site should be within a buffer of one kilometre from the river. This was considered an economically sustainable distance from the river (Experts opinion) |
| Proximity to Roads | 7 | The dam site should be easily accessible, so that it can be economically connected to the required population [17] |
