RESUMO:

The anthropic use of soil in waterfront zones causes reduction of its quality, increasing the vulnerability of the soil to erosion and consequently increasing the acting's potential as a diffuse source of nutrients and contaminants to the superficial water bodies. The soil formation process is influenced, among other factors, by the climatic characteristics of the regions. Due to the low pluviometric regime, the soils in the semiarid regions are plain, little structured and have a rough texture. In tropical regions, due to high temperatures and increased availability of water, the soils are structured, deep and have a thinner texture formed from the high degree of weathering. The tropical soils present a lower flow rate and soil loss compared to semiarid that are plain and thick textured. This work's goal is to study the soil response from different regions to the use and anthropic occupation of the waterside zone and its relation with water quality in aquatic ecosystems. This work hypothesis is that soil covered with natural vegetation in waterfront zones preserves the soil and water quality. This study will rate eleven waterfront zones located in counties of different regions of Rio Grande do Norte. In the semiarid, the waterside zones of  Boqueirão de Parelhas tank, Cruzeta, Dourado, Engenheiro Armando Ribeiro Gonçalves, Itans, Marechal Dutra (Gargalheiras) and Passagem das Traíras will be evaluated. On the coast, the waterfront zones of the Lagoas de Boqueirão, Extremoz, Bonfim and Jiqui. This study will bring attention to the classification of waterfront causing better use and occupation of these soils. Each class of soil use and occupation will be analyzed soil physical and chemical attributes (soil density, grain size, pH, organic matter and organic carbon) and limnological water data (dissolved oxygen, phosphorus, chlorophyll a, nitrogen and turbidity). In order to identify which soil characteristics dictate the alteration of its quality and which anthropogenic uses have the greatest potential to provide nutrients to aquatic ecosystems, Principal Component Analyzes (PCA) will be carried out with soil physicochemical attributes and limnological data. This study hopes to gain a broader understanding of how the various anthropogenic uses influence soil degradation in waterside zones and increase its performance as a source of diffuse pollution for surface water bodies.
