Doce River

Despite the growing literature and empirical research on citizenship participation in the elaboration of water resources plans (WRP), little attention has been paid to the Terms of Reference (ToR) for such plans. Such a technical contract sets the targets, stages and activities to be met as part of the development of the WRP. Thus, any analysis of the participation impacts and results must follow the previously agreed terms but the ToR development may not, in itself, be participative. Examined herein are the ToR for the WRP of the Doce River Basin (Brazil) and the Catalonia Fluvial District (Spain), with focus on (i) proposals for democratising debates and decisions and (ii) the very process of ToR development. Historical and institutional aspects of both regions were analysed, which comprised participation mechanisms established by the corresponding national policies and recommended by the relevant international bodies. Despite the distinct features of the two regions, they both share the challenge of implementing a new governance model involving various stakeholders with the common goal of defining the water usage rights in a sustainable way. A comparative analysis of the two approaches revealed different approaches to tackle this challenge and highlighted advantages and disadvantages of each model.

This research seeks to identify the development stage of the cooperation to manage the resources employed in the Rio Doce River Basin restoration, analyzing strategies for improving the results of such cooperation. This qualitative and quantitative descriptive research used semi-structured and structured interviews. The study applied a model of analysis of cooperative relations among agencies responsible for managing resources destined for the basin’s restoration, identifying the cooperation’s development stage.

Macrophytes are plant organisms that live partially or totally submerged in water, being fixed and free. The Doce River is one of the main rivers in southeastern Brazil and, in 2015, it was hit by ore tailings from the Fundão dam burst in Mariana, Minas Gerais. This work aims to provide a floristic survey of macrophytes in the lower Doce River basin and to compare the species composition between lentic and lotic environments. Expeditions were carried out monthly from October 2018 to September 2019, in five stations in lotic and six in lentic environments. A total of 105 species belonging to 33 families of vascular plants were recorded, among them 14 are new occurrences for Espírito Santo state. Richest families were Poaceae (23 spp.) and Cyperaceae (22 spp.). Amphibious/emerging plants were the most representative (46 spp.). NMDS analysis revealed that the composition of the lotic and lentic environments are different.

ABSTRACT This study aimed to develop a methodology based on multivariate statistical analysis of principal components and cluster analysis, in order to identify the most representative variables in studies of minimum streamflow regionalization, and to optimize the identification of the hydrologically homogeneous regions for the Doce river basin. Ten variables were used, referring to the river basin climatic and morphometric characteristics. These variables were individualized for each of the 61 gauging stations. Three dependent variables that are indicative of minimum streamflow (Q7,10, Q90 and Q95). And seven independent variables that concern to climatic and morphometric characteristics of the basin (total annual rainfall – Pa; total semiannual rainfall of the dry and of the rainy season – Pss and Psc; watershed drainage area – Ad; length of the main river – Lp; total length of the rivers – Lt; and average watershed slope – SL). The results of the principal component analysis pointed out that the variable SL was the least representative for the study, and so it was discarded. The most representative independent variables were Ad and Psc. The best divisions of hydrologically homogeneous regions for the three studied flow characteristics were obtained using the Mahalanobis similarity matrix and the complete linkage clustering method. The cluster analysis enabled the identification of four hydrologically homogeneous regions in the Doce river basin.
