The Shire River flows from Lake Malawi into the Zambezi River in Mozambique. In the southern Malawi, the Shire is an important water resource for irrigation, water supply, ecological functioning of several protected areas, including the Majete Wildlife Reserve, and electricity production. A new 350 MW hydropower project (HPP) is proposed in the Middle Shire, at Mpatamanga Falls. As every dam, Mpatamanga dam will have an impact on sediment continuity and therefore, on the channel morphology of the Shire River upstream and downstream of the dam. Sediment studies are fundamental to identify and quantify those future sediment impacts by improving our understanding of the sedimentary functioning of the river system. This paper describes the several sources of information and tools available to support the baseline understanding of the Shire River. The tools described include field visits, sediment yield and soil erosion models, geomorphological analysis and sediment budget. Although there are considerable uncertainties in the available data to support quantitative sediment budget estimations, deposition and erosion trends were identified and lessons learnt from the operation of existing dams in the Shire River.
