Brief_description
Sabaki River Mouth is where the Athi-Galana-Sabaki river system empties into the Indian Ocean some 5 km north of Malindi. Due to the combined action of ocean currents and freshwater flow from the highlands bringing high levels of silt, a diverse array of habitats have been formed. These include open sandy beach, sandbanks, mudflats, salt marsh, vegetated and bare sand dunes, seasonal and permanent fresh water pools, mangroves, grassland and coastal scrub. Since the mid-1970s a high level of silt deposition has taken place that has extended the river mouth into the ocean and created the wide, open mud and sand flats which are the key attraction for large numbers of waders. Until c. 2000 there was only some degraded patches of mangrove forest slightly upstream. With the siltation, however, conditions became ideal for mangroves to become established and an area of over 12 ha of mangrove forest has grown on the northern banks of the river mouth. Seasonal wetlands form during seasons of good rain on the extension of low sand dunes between the beach and the old, high sand dunes and provide breeding habitat for some birds such as Black-winged Stilts. The sandflats and beach are regularly used as a roost for often large numbers of gulls and terns which forage out at sea and come to the relative safety of the river mouth to rest.
Physical_features
A series of high (up to c. 25 m) wind-blown sand dunes extend about five km north and three km south of the river. These dunes form an important aquifer and as a result among the dunes are pools and wells of fresh water filtered by the sand and separ
Hydrological_features
"Sabaki" is the name of the final few kilometres of the river that starts in the Ngong Hills west of Nairobi as the Athi River and is known as the Galana River through Ukambani and Tsavo East National Park. At its mouth it is c. 150 m wide broadening
