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 Water meadows have been replaced by arable fields and building developments, altering drainage patterns and causing pollution.
