- The Tana river is the most important river in Kenya in view of its role in national development.
- Five HEP dams in the Upper Tana Basin - Kindaruma, Kiambere, Kamburu, Gitaru and Masinga.
- The Masinga Dam is the most significant in terms of regulating the hydrology of the Tana river due to its size.
- Studies on the effects of soil erosion and impacts in the Upper Tana Basin (e.g. Dunne and Ongwenyi, 1976; Ongwenyi, 1978; Edwards, 1979; Ongwenyi, 1985; Brown et
al., 1996; Schneider and Brown, 1998; Pacini et al., 1998; Maingi and Marsh, 2001; Maingi and Marsh, 2002).
- Studies on the effects of landuse change and water abstraction on streamflow in the Upper Tana basin (Njogu et al., 2018) and Mwendwa et al 2019).
- Studies on the environmental impacts of the hydrologic alterations of the flow of the Tana river on the riverine forests (Pacini et al., 1998; Maingi and Marsh, 2001; Maingi
and Marsh, 2002).
- Few studies on the hydrology of the Tana river in the Lower Tana Basin (Kitheka et al., 2003 and 2005)
