Fee demonstrated that the tumdisi depth is a critical factor controlling the magnitude of primary production in most lakes. We used a sub-routine from the software Didger 3.
The volume and water retention time, for example, are essential for estimating the carrying capacity for fish production, or even to detect the fate of nutrient and contaminants in a lake Sampaio et al. Tunxisi of native fish fauna by alien species: Oivro large data matrix generated by the many sampling points made possible a detailed description of the lake basin. Morphometry of four lakes in the Rio Doce Valley Lakes system and its relationships with primary production of phytoplankton.
The next step was to overlay two different geographic information plans maps: These estimates made it possible to construct a hypsographic curve depth x area lines Figure 4. Identification of partial discharge signals. As well as focussing on the history of Limnology, the first ten chapters focus on water as a substrate, lijnologia origin of lakes and aquatic biota and their interaction with environmental factors.
The lake surface Athe bottom area Ba and the lake volume V were estimated from Surfer 8. Black star indicates the location of maximum depth In this study, each layer was 4 m thick.
Considering the differences observed in lake area and volume between our and the previous study Table 3we also suggest a revision of some aspects of lake function, such as heat content or lake stability and oxygen deficit, that have been published based on the older estimations e.
In Brazil, several lakes have been intensively studied over the past decades. They estimated a volume of only 8. Admirably, the authors have been attentive to introducing into the text information which originates from studies carried out in the Tropics and mainly, from Brazil.

So neither will Limnologia be restricted to the geographical limits of Brazil. In this article, the reader can find a bathymetric chart as livr Acta Limnol. It also brings precious information to those who use knowledge in an applied way, such as water resource technicians and managers. Morfometria de Lagos e Represas. The maximum depth was read directly from the field-data matrix.

This data matrix was processed by the Tundisk program, using the Kriging interpolation method. The process of finding data values for unknown locations between observed data locations is known as interpolation.
Material and Methods 2.
The objective of this investigation was to update existing information on the bathymetry and morphometric features of the lake, using differential GPS DGPS technology for data collection, coupled to a digital echosounder. The lake usually reaches its maximum level just after the rainy season November-March.
Luiz Carlos Rezende e Santos. The most difficult step was to obtain an affordable cartographic basis, since it is crucial limnoloogia calibrate the shoreline for this kind of investigation. Surface interpolation and contour map The spatial data collection of this survey can tudisi considered luvro sampling values, and to obtain regular grid data for the entire area of the lake, the data must be interpolated.
Several authors have proposed that lake area is a determinant parameter to define the depth of the thermocline Acta Limnol. This project selected the Rio Doce lakes as the main study area. This chart corresponds to the beginning of the dry season May, when the lake was at its maximum level Figure 1. However, limnologiia new tools have so far not been applied in most freshwater systems of Brazil.
We also thank the staff of the Parque Estadual do Rio Doce for their collaboration. Acknowledgements The authors thank Dr. These differences are clearer in tundlsi view Figure 3. Because lake volume and lake area are primary morphometric parameters, these parameters are used in the estimations of all other secondary morphometric features of a lake Cole,von Sperling, The park has an area of 36, ha, and preserves the largest remaining fragment of the Atlantic Forest in the state Latini and Petreri, Single depth yundisi were taken where navigation was not possible macrophyte beds or where the maximum depth was less than 1.
The shoreline points were obtained from calibrated high-precision 1: In addition, this new technology must be applied in a scientific context. According to Colethe accuracy of every bathymetric chart is directly dependent on the number of sampling tundsi.

These livgo, in turn, are fundamental to understand the functioning of aquatic ecosystems. The new morphometric information differs substantially from previously published values Tables 1 and 2.
The contours of the lake bottom are surprisingly complex. This is an unquestionably complete, up-to-date and extremely information-dense compendium. The other lake arms are shallower, with depths of 6 to 8 m.
Additionally, this contribution re-evaluated the basic morphometric features and discussed the differences between the new estimates and existing information.
Dozens of scientific articles, research reports and popular brochures have been published, with this lake as the major study area.
Therefore, it is also necessary to develop new research efforts aiming to identify the existence of longitudinal horizontal patterns in different limnological variables such as chlorophyll a, plankton community and fish assemblage. This line is made of many points geographic coordinates that assume the value of Z is zero. Parameters This study Volume x m3 Investigation of physical and bathymetric characteristics of Lakes Abaya and Chamo, Ethiopia, and their management implications.
The transducer of the echosounder and the kinematics antenna of the DGPS were set on opposite ends of the same metal tube, with the goal of reducing errors in positioning due to the inclination of the boat.
