The water from the Vaal Dam is purified at two purification stations in Vereeniging and This was because the dam's catchment area had remained dry for the previous four monsoons, resulting in a complete stoppage of supply to the city on July 14, 1999. 75 2 Department of Water 1.3 Catchment details 1.3.1 Physiography The Kirup Dam Catchment Area (KDCA) is located within the Darling Plateau which consists of an undulating, dissected peneplain. Administratively it is located within Theewaterskloof Local Municipality. erosion in the catchment area. Life span of a reservoir in case of a seasonal storage dams and barrages is greatly reduced due to erosion in the catchment area. Natural and human systems such as rivers, bushland, farms, dams, homes, plants, animals and people can co-exist in a catchment.” Kirup Dam Catchment Area Drinking Water Source Protection Plan Water Resource Protection, Report No. The catchment area is the total area of land that contributes runoff into the dam. 1.Catchment area A river drains the water collected from a specific area, which is called its catchment area 2.Watershed The land area that drains runoff( rain or snow) into a lake, river , or a stream is called watershed. Primarily the catchment area management includes ground water recharge, knowing terrain characteristics i.e. I have a DEM of my study area, and polyline shapefile of the Dams in that area. > Methods. A total of 55 … Following precipitation of 138 mm in the catchment areas of Papanasam dam, water level in the second largest dam of the district rose by 9.70 feet in 24 hours. Objective. I know that you can find the Watershed contributing to a pour point, but how do you use the Damlines, to get the catchment Area contributing water to the dam's reservoir? Abstract— The catchment and command area management of a dam includes various parameters to be studied. The developmental projects, particularly construction of dams, result in permanent changes of terrestrial ecosystems through inundation. The catchment area intercepted at the diversion structure of Kangtangshiri barrage site is 810 km2. This is Catchment area: 500 km 2: Surface area: 5 059 ha: Theewaterskloof Dam is an earth-fill type dam located on the Sonderend River near Villiersdorp, Western Cape, South Africa. Catchment Area. catchment areas into the Vaal Dam catchment. For relatively small catchments it may be possible to determine their area from farm plans, aerial photos of the farm or by actually measuring it out on the ground with a vehicle or global positioning system (GPS). I have run the standard Hydrology tools on it (Fill, Flow Direction & Flow Accumulation). The present study was undertaken aiming at documenting useful plant species in Ntabelanga dam catchment area that will be impacted by the construction of the proposed dam. “A catchment is an area where water is collected by the natural landscape. In a catchment, all rain and run-off water eventually flows to a creek, river, lake or ocean, or into the groundwater system. In order to calculate the annual inflow into the dam, a surface runoff of 10mm was assumed for these relatively flat catchment areas. The catchment area of the various dams is indicated by small dashes/circles/crosses in figures 1 through 3, and quantified in km2 in table 1. slope of the ground, finding water logging areas etc. These schemes are the Thukela Vaal Water Transfer Scheme and the Lesotho Highlands Water Project. Soils are predominantly gravels with Background. This is important because of the growth of Gauteng in terms of industry and the amount of people.
