Potencial da bacia do rio Movene para construção da barragem: uma análise quantitativa e qualitativa da água do rio

Abstract

This work is a contribution in the field of hydrology with a view to benefiting from the natural hydrological cycle for hydraulic developments; from the specific case study of the Movene river sub-basin, where the author makes a quantitative and qualitative analysis of the river water for the construction of the dam (Movene II) in the Umbelúzi hydrographic basin. The work presents the antecedents of some studies with a differentiated approach on the subject, where the fundamental concepts of water quality analysis are included; and some models in the study area were analyzed and tested, such as “River Basin System WAFLEX”, Qualitative Parametric Water Model, Based on Criteria or Standards (for agriculture and human consumption). The results obtained show that the spatial and temporal variation of precipitation, within the natural geographic limits, physically determines the flow of the Movene river, where the annual average over 40 years (1954-1994) is 2.5 m3/s ( 78 Mm3/s), acceptable for the construction of the projected dam (Movene II), with a storage capacity of approximately 28 M m3/s; and the water quality in the Movene basin presents acceptable levels for the development of activities economical.(TRADUÇÃO NOSSA)
