The aim of this learning was to recognize the biospontaneous environment and narrate the weight of the steep budget concept to their discernment of the hydrologic cycle, steep media and steep expedients conduct. To understand and ponder the general plight of Gaborone dam in stipulations of its act and sustainability of services. We base out that steep utilities confirmation operates the Gaborone dam.
One of the presentation of the learning was to indicate the factors that rule the productivity and conduct of these steep media and to understand the drifts encountered. Evaporation is a senior solicitude of steep forfeiture at the Gaborone dam. Unfair fishing, poaching and defilement are some of the drifts that encountered at the dam. To understand the coming strategies in seemly and supported the profit and productivity of Gaborone dam in stipulations of enlargement, deprotect or deprivation of media after a while honor to increasing ask-for of collection. The learning was carried by traditional consultation and study which were the methods used for collecting axioms.
A learning on steep media was carried out at the Gaborone dam to ponder the general plight of Gaborone dam in stipulations of its act and sustainability of services. The dam is operated by the Steep Utilities Confirmation (WUC), and it anticipation steep to the accommodation of (Gaborone Department of Environmental Affairs. 2006. Steep Accounts of Botswana 1992-2003).
The Gaborone Dam is located south of Gaborone parallel the Gaborone-Lobatse course, and provides steep for twain Gaborone and Lobatse The dam is assiduous up by neighboringby large tides which are Tlwane, Notwane and Nnyane large tide Notwane large tide animation the main tide. The learning was to-boot carried out to understand coming strategies in seemly and supported the profit and productivity of Gaborone dam in stipulations of enlargement or deprivation of media after a while honor in increasing ask-for of collection.
Expanding the steep tenor sets and lay-hands-onments get succor in supported and providing steep if there is an growth in ask-for of collection in the coming. Determining the factors that rule the productivity and conduct of these steep media and to understand the drifts encountered. Unfair fishing is one of the drifts encountered at the dam. The learning was to-boot carried out to recognize the biospontaneous environment and narrate the weight of the steep budget concept to their discernment of the hydrologic cycle, steep media and steep expedients conduct.
Materials and Methods
We began our scope 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 kernel of the dam is made by clay that's why it is secure (Du Plessis, A. J. E., and K. M. Rowntree. 2003 Du Plessis, A. J. E., and K. M. Rowntree. 2003). It was picturesque to be 141.1 Million Cubic Meter which is the tenure accommodation and it is 3.5 kilometres which is the extension of the dam embankment.
We were told that the dam is operated by the Steep Utilities Confirmation which was another assign that we visited during the scope stumble. We visited the assign to see the tenor set there but the biggest steep tenor set is at Mmamashia. An traditional consultation was carried out as a way of collecting axioms environing the Gaborone dam.
Results and Discussions
The Gaborone dam which is 141.4 Million Cubic meters is assiduous up by the Notwane Large tide which is the main tide of the dam. Even if the dam was built for a good-natured-natured design there was some consequences faced during the fabric of the dam which fictitious the biospontaneous environment. One of the impression is the alteration uptide of the dam from a free-flowing large tide ecomethod to an pretended slack-steep reservoir habitat.
Changes in temperature, chemical commutation, dissolved oxygen levels and the spontaneous properties of a reservoir are repeatedly not convenient to the aquatic sets and animals that evolved after a while a attached large tide method. Indeed, reservoirs repeatedly army non-native and invasive nature (e.g. snails, algae, and plundering fish) that elevate counteract the large tide's spontaneous communities of sets and animals. The dam embankment itself blocks fish migrations, which in some cases and after a while some nature liberaly different spawning habitats from rearing habitats.
The dam to-boot traps sediments, which are exact for maintaining spontaneous processes and habitats downtide of the dam. The dam is to-boot confrontment some drifts such as defilement which is for-the-most-part caused by civilized animations buildation neighboring the areas of the dam. Steep defilement is a grave effect as it can interest the marine animation and the steep attribute. Steep evaporation is to-boot one the impressions that interests the productivity of the dam as a lot of steep is obsolete almost entire day to the temperature. The Gaborone dam uniformly got liberal at the steep spilled to neighboringest homestead and it not prudent to feed neighboring the dam.
There is exalted rates of unfair fishing at the Gaborone dam as crowd buildation neighboringby lay-hands-on fishes for buildation and proceeds. But this effect is inferior as there are patrols importation assign. Most animals are base deserted on the dam which is to-boot steep defilement, to elude this drift a protect is built to elude animal's drinking steep from the dam. So far the general drifts importation assign at the dam are evaporation, defilement, poaching and unfair fishing.
In the coming the population of Gaborone residents get growth and this get direct to steep shortage, the dam should be large to elude this drift in the coming. Lack of Rainfall is to-boot one of the drifts that we are confrontment in Botswana Main annual rainfall varies from zenith of 650 mm in Kasane to a incompleteness of hither than 250 mm is the Kgalagadi (Tsabong) (Department of Meteorological Services. n.d.
