Повний текст джерелаImproved knowledge is required on the quantity and source of water resources, particularly evident during periods of drought currently being faced in South Africa. There is inadequate knowledge with regards to the flood attenuating properties of wetlands, particularly evident in the ungauged catchments of Southern Africa. This study aims to improve the knowledge on the contribution of flow from tributaries with headwaters in mountainous regions to low lying areas and the effects of wetlands on river flow patterns. Several river flow monitoring sites were established along the major upper tributaries of the Nuwejaars River at which daily water levels were recorded and bi-weekly discharge measurements were conducted. Weather data was collected using four automatic weather stations and three automatic rain gauges’ setup throughout the catchment. Rainfall data coupled with rating curves and daily discharges were used to assess the flow responses of these tributaries to rainfall events. Additionally, stable isotope analysis and basic water quality analysis was used to determine the major sources of flow within the major tributaries. The rainfall and river flow data collected, coupled with the characterization of the wetland was used to determine the flood attenuation capabilities of the wetland. Lastly, a conceptual model based on a basic water balance was developed to further explain the role of the wetland and its effects on river flows. The results showed a 27-hour lag time in peak flows from the upper tributaries at the inflows of the wetland to the outflow. Two of the upper tributaries had flow throughout the year and were fed by springs in the upper mountainous regions of the catchment and all tributaries were largely reliant on rainfall for peak flows. The temporary storage of flows within the wetland occurred as a result of the Nuwejaars River bursting its banks, filling of pools, or ponds and the Voëlvlei Lake. It was concluded that the wetland increased the travel time and decreased the magnitude of flows of the Nuwejaars River. However, due to the fact that wetlands are interlinked on a catchment scale and have a collective effect on flood attenuation this study may be improved by looking at the wetlands within the catchment holistically.

The objective of this study was to evaluate the effects of floods and drought on the macroinvertebrate richness, density and composition in two wetland classes (palustrine wetland and oxbow lake) associated to a floodplain system of the Sinos River basin over an annual cycle (2003-2004). The studied area was located in Novo Hamburgo city (Lomba Grande), in the South of the Brazil (Rio Grande do Sul). In each wetland class, twelve collections were carried out during an annual cycle (Apr 16/2003 to Mar 12/2004). In each collection, five samples were collected at random along an transect. The collections were developed using a corer (75 mm diameter) inserted 5 cm into the substratum. A total of 1,229 macroinvertebrates representing 50 taxa was observed in the oxbow lake and 1,930 macroinvertebrates distributed in 48 taxa were collected in the palustrine wetland. The majority of the taxa corresponded to aquatic insects (67.3% in the oxbow lake and 69.4% in the palustrine wetland). The macroinvertebrate richness (

Thesis, Linköpings universitet, Tema Miljöförändring, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-153908.
Повний текст джерелаTropical wetland-adapted trees are recognized as an important source of regional and global methane (CH4) emissions, by transport of soil gas through wetland trees. However, spatiotemporal variability and controls on the magnitude of tree-mediated CH4 emissions remain unknown as fluxes are poorly constrained. Therefore, we aim to optimize sampling efforts to yield representative emission estimates for distinct types of forest ecosystems and improve knowledge on spatial and temporal variability. We examined the variability in tree stem mediated CH4 fluxes in situ, located in three different floodplains (Solimões, Negro and Tapajós) with various characteristics, during different hydrological seasons. The sampling was conducted by measuring fluxes from 36 trees at each location using closed chambers. All the three study sites, situated in the Amazon region, displayed seasonal variability in CH4 fluxes, with the largest contributions observed during the wet season. A significant difference between Solimões and Negro was detected during the wet season and this may be a result of the different chemical and physical characteristics between the sampling locations. As for within the study sites, zones played a significant role for CH4 flux from trees since the water level influences the fluxes. A strong spatial variability (lower fluxes in the land zone, and the highest flux obtained in the zone with greatest variability between dry and wet conditions) was found. This pattern can be addressed by sampling along flooded and non-flooded zones.

Повний текст джерелаFrom September 1999 up to November 2000 a wetland of the right margin of Feijão river floodplain was studied with the objective to verify its activity as an natural filter to retain organic matter making use of a simulation model constructed with the help of the Stella software. Were collected climatological data from an automatic climatological station (air temperature, air moisture, rain, solar radiation, speed and wind direction and atmospheric pressure), from piezometers installed within the wetland (number of 9) and samples collected of river water, limnological data: physical data (water temperature, turbidity, dissolved oxygen, conductivity and depth); chemical data (total phosphorus, total dissolved phosphorus, silicate, total nitrogen, nitrate, nitrite and ammonium), moreover data obtained from literature and papers published of sites near the study area. From the interrelationship of processes occurring within the Feijão river floodplain wetland was constructed the simulation model. The obtained conclusions indicate the good simulation model behavior and show that time scales should be shorter in future wetland studies. Other conclusion refer to wetland conduction as a natural filter where occurred carbon storage (organic matter). Great amplitude of water table diary variation have been verified within the wetland due to evapotranspiration. Is possible to recommend the river preservation because 40% of the surface city supply is from this site.

Повний текст джерелаThe aim of this study was to verify the spatial and temporal dynamics of natural wetland limnological variables, in Jacupiranguinha river, a micro basin from Ribeira de Iguape Valley, under distinct hydrological pulses. This was made to infer these systems capacity in depurating or retaining potentially polluting nutrients in wetlands. It was selected 11 sample points: 1 and 2 in Jacupiranguinha river; 3 in Serranas brook; 4 to 10 in wetland system and 11 in the exit of the system, next to Jacupiranguinha river. Samples were collected in four different periods for nutrients determination, BOD, COD, fecal and total coliforms analysis. In sediment was determined nitrogen and phosphorus concentrations and organic matter. It was collected aquatic macrophytes too. Temperature, electric conductivity, pH and dissolved oxygen were measured with YSI probe. Topography was determined and a batimetric study was made in floodplain; besides, it was installed hydrometric rulers in the area. Discharge and hydrometric levels of Jacupiranguinha river were positively related with precipitation. The floodplain ponds were not permanently connected with fluvial course; it is necessary values above 2,47 meters to overflow the wetland and connect it with the river. With the software PULSO was observed 5 and 3 complete pulses, with respectively 2,47 m and 2,97 m of topographic level. Duration of pulse phases (potamophase and limnophase) was different, and limnophase had predominated. Pulse regime seems to homogenize the system. Seasonal and spatial differences were observed in water limnological variables. The differences in sediment were not significant; however it showed the higher nitrogen, phosphorus and organic matter concentrations in the two ponds. Higher coliform concentrations were registered in points 1 and 2. The aquatic macrophytes present in the studied wetland were very important in nitrogen and phosphorus cycle and retention of these nutrients in their biomass. In terms of load reduction, nitrogen, phosphorus and BOD were considerable reduced in dry season. Thus, pulse regime maintains the wetland connected with Jacupiranguinha river and guide the biotic and abiotic factors dynamics, very important factors for a better operation of the system, serving as nutrient storage and depurative. However, we recommend the construction of an artificial wetland system to complement the waste treatment in the studied area.

Повний текст джерелаIt is very important to improve our knowledge about the floodplains, which have been proved by studies, since these areas are vital to the maintenance and preservation of the quality of waters and the fluvial ecosystem. This fact, associated with the importance of the wetlands-river system, makes its investigation and preservation to be considered number one priority. The objective of this research is to analyze factors that may influence hydrographs, according to the fluvial ecology of wetlands in micro basin of Baixo Ribeira do Iguape Valley, SP. The work began with the definition of the studied field and its importance to the area. Subsequently, five hydrometric station and one meteorological station were installed, and therefore the rating curve in the entrance of floodplain was calculated along with the uncertainties related to its parameters. With these studies and with the topographic survey, it was possible to find the relation between wetlands, river stage and flow. The climatologically information, the river stage and the superficial covering vegetation are essential factors to determinate the components (precipitation, superficial flow, evaporation and the storage) of the water balance at the micro basis of Jacupiraguinha river. The hydrometric observation of the river along with historical series and the probability-duration curve make it possible to calculate the ecological flow. Finally, conceptual charts integrating the relations between hydrological and limnologicals factors were built showing the strong association with the wetlands-river system.

Повний текст джерелаThe general perception today is that the Shashi-Limpopo Basin in southern Africa is hot and dry and not conducive to human habitation. Today there is no doubt that the Shashi-Limpopo Basin has been home to many communities throughout the pre-historical period. A study of the changing ecological conditions in the Mateke Hills and the Shashi-Limpopo Valley as well as historical and present day land-usage offers an alternative explanation of how prehistoric communities could have interacted with this changing landscape. The archaeological record, historical sources and recent land-use patterns show that settlement location has always been orientated towards the rivers and circumscribed environments. The mosaic of floodplains, wetlands, drylands and circumscribed zones provided the ideal ecological setting for the development of socio-political complexity in southern Africa. The resilience of these semi arid savanna regions together with human innovation and local knowledge ensured that societies continued to derive subsistence even in the face of seasonal variability in rainfall and even climate change.
