Netwaye peyi a ak pwojè konstriksyon ka chanje modèl drenaj natirèl yo, sa ki lakòz dlo dous, eleman nitritif, ak sediman ekoulman sou resif adjasan. Sedimantasyon ka dirèkteman toufe yon resif oswa ogmante toruite nan dlo yo bò lanmè, ki diminye limyè ki disponib nan koray ak senbyot yo. zooxanthellae. Koray depann de zooxanthella yo pou jenere manje fotosentetik, kidonk privasyon limyè ka lakòz koray ap mouri grangou. Pandan ke kèk resif koray boujonnen nan dlo turbid, resif yo tipikman mwens divès epi yo gen plis restriksyon nan chenn pwofondè pase sa ki nan dlo klè.ref Konbinezon sediman ki sispann, re-sispann, ak depoze ka limite kwasans koray, modèl manje, fotosentèz, rekritman, ak sivivan.

Land clearing and construction projects may change the natural drainage patterns, resulting in freshwater, nutrient, and sediment runoff onto adjacent reefs. Sedimentation can directly smother a reef or increase turbidity in the coastal waters, which reduces light available to corals and their symbiotic zooxanthellae. Corals depend on their zooxanthellae to generate food photosynthetically, therefore light deprivation can cause corals to starve. While some coral reefs thrive in turbid water, the reefs are typically less diverse and are more restricted in depth ranges than those in clear water.ref The combination of suspended, re-suspended, and deposited sediment can limit coral growth, feeding patterns, photosynthesis, recruitment, and survivorship.
