| 11. | Groundwater movements, topography, and drainage pattern were taken into place when selecting areas for recovery.
|
| 12. | Repeated glaciations have had a profound impact on shaping land forms and determining drainage patterns.
|
| 13. | This elevated region has a natural drainage pattern that rarely functions because of insufficient rainfall.
|
| 14. | Sinkholes can also form when natural water-drainage patterns are changed and new water-diversion systems are developed.
|
| 15. | Malaitan hydrology includes thousands of small springs, rivulets, and streams, characteristic of a young drainage pattern.
|
| 16. | The drainage patterns are immature and poorly established.
|
| 17. | That will prevent them from causing erosion and upsetting the drainage patterns that stunt the plants'growth.
|
| 18. | The dentritic pattern, or an angular drainage pattern.
|
| 19. | Soil management can take place through rearranging soils, altering drainage patterns, and building large earthen formations.
|
| 20. | Water meadows have been replaced by arable fields and building developments, altering drainage patterns and causing pollution.
