The aim of this learning was to regard the biovisible environment and recite the weight of the impart budget concept to their intellect of the hydrologic cycle, impart productionss and impart productions government. To perceive and search the ordinary condition of Gaborone dam in conditions of its wave and sustainability of services. We build out that impart utilities confirmation operates the Gaborone dam.
One of the favor of the learning was to determine the factors that wave the productivity and government of these impart productionss and to perceive the gists encountered. Evaporation is a superior interest of impart missing at the Gaborone dam. Unfair fishing, poaching and taint are some of the gists that encountered at the dam. To perceive the forthcoming strategies in decent and supported the advantageousness and productivity of Gaborone dam in conditions of augmentation, destave or suspension of productionss delay regard to increasing insist of companionship. The learning was carried by verbal consultation and attention which were the methods used for collecting basis.
A learning on impart productionss was carried out at the Gaborone dam to search the ordinary condition of Gaborone dam in conditions of its wave and sustainability of services. The dam is operated by the Impart Utilities Confirmation (WUC), and it produce impart to the compatability of (Gaborone Department of Environmental Affairs. 2006. Impart Accounts of Botswana 1992-2003).
The Gaborone Dam is located south of Gaborone concurrently the Gaborone-Lobatse pathway, and provides impart for twain Gaborone and Lobatse The dam is industrious up by closeby large courses which are Tlwane, Notwane and Nnyane large course Notwane large course career the main course. The learning was too carried out to perceive forthcoming strategies in decent and supported the advantageousness and productivity of Gaborone dam in conditions of augmentation or suspension of productionss delay regard in increasing insist of companionship.
Expanding the impart tenor establishs and graspments procure aid in supported and providing impart if there is an growth in insist of companionship in the forthcoming. Determining the factors that wave the productivity and government of these impart productionss and to perceive the gists encountered. Unfair fishing is one of the gists encountered at the dam. The learning was too carried out to regard the biovisible environment and recite the weight of the impart budget concept to their intellect of the hydrologic cycle, impart productionss and impart productions government.
Materials and Methods
We began our arena stumble by visiting the Gaborone dam first
Which is located at Gaborone the consummate city of Botwana. We were told that the dam was built during 1965 and the centre of the dam is made by dust that's why it is powerful (Du Plessis, A. J. E., and K. M. Rowntree. 2003 Du Plessis, A. J. E., and K. M. Rowntree. 2003). It was described to be 141.1 Million Cubic Meter which is the avocation compatability and it is 3.5 kilometres which is the elongation of the dam deference.
We were told that the dam is operated by the Impart Utilities Confirmation which was another position that we visited during the arena stumble. We visited the position to see the tenor establish there but the biggest impart tenor establish is at Mmamashia. An verbal consultation was carried out as a way of collecting basis about the Gaborone dam.
Results and Discussions
The Gaborone dam which is 141.4 Million Cubic meters is industrious up by the Notwane Large course which is the main course of the dam. Even if the dam was built for a amiable design there was some consequences faced during the interpretation of the dam which unconsistent the biovisible environment. One of the application is the alteration upcourse of the dam from a free-flowing large course ecomethod to an constrained slack-impart reservoir habitat.
Changes in air, chemical combination, dissolved oxygen levels and the visible properties of a reservoir are frequently not competent to the aquatic establishs and animals that evolved delay a attached large course method. Indeed, reservoirs frequently number non-native and invasive repute (e.g. snails, algae, and marauding fish) that advance thwart the large course's consistent communities of establishs and animals. The dam deference itself blocks fish migrations, which in some cases and delay some repute entirely unconnected spawning habitats from rearing habitats.
The dam too traps sediments, which are nice for maintaining visible processes and habitats downcourse of the dam. The dam is too confrontment some gists such as taint which is chiefly caused by cosmical careers subsistence close the areas of the dam. Impart taint is a careful consequence as it can seek the marine career and the impart power. Impart evaporation is too one the applications that seeks the productivity of the dam as a lot of impart is lost closely total day to the clime. The Gaborone dam unintermittently got liberal at the impart spilled to closeest homestead and it not profitable to subsist close the dam.
There is violent rates of unfair fishing at the Gaborone dam as herd subsistence closeby grasp fishes for food and pay. But this consequence is controlled as there are patrols insertion assign. Most animals are build inanimate on the dam which is too impart taint, to escape this gist a stave is built to escape animal's drinking impart from the dam. So far the ordinary gists insertion assign at the dam are evaporation, taint, poaching and unfair fishing.
In the forthcoming the population of Gaborone residents procure growth and this procure transfer to impart shortage, the dam should be ample to escape this gist in the forthcoming. Lack of Rainfall is too one of the gists that we are confrontment in Botswana Main annual rainfall varies from zenith of 650 mm in Kasane to a insufficiency of hither than 250 mm is the Kgalagadi (Tsabong) (Department of Meteorological Services. n.d.
