Seasonal rains produce muddy rivers, with higher sedimentation than northern countries' dams filled with melted snow.

Increased soil erosion and sedimentation rates can also jeopardize the array of ecosystem ser-vices provided by the watersheds.

These factors include high water temperatures, pollution, sedimentation, high light levels, reduced water levels and changes in salinity.

The major issue regarding the viability of the project is going to be the sedimentation rate of the catchment.

The major threats are from coastal development, destructive fishing practices, overexploitation of marine resources, marine pollution and sedimentation from inland deforestation and farming.

In some locations, sedimentation created sufficient pressure to convert -- to cook -- the unoxidized carbon in the organic material into oil, some of which was trapped in reservoirs.

According to the results of the new study, similar processes, including tectonic upheaval, icy lava eruptions, erosion and sedimentation by rivers, may also be factors on Saturn's largest moon.
