Abstract
:
This study conducted on Baysh Dam Lake in Jazan. The water in the dam lake were investigated in term of quality and lake’s surface area effects. Regarding the quality, the concentration of Chlorophyll in the dam’s lake is an indication of growing Algae. Also, the Nitrogen content in Baysh dam lake is a sign of extensive eutrophication. The Chlorophyll concentration and the Nitrogen content in the lake were estimated by using satellite images from the space. Data from satellite images were adjusted and confirmed by analyzing water samples from the water surface of Baysh dam’s lake. Samples were test at the directorate General of Water in Jazan which is under the ministry of Environment Water and Agriculture. Turbidity, watercolor and Nitrate concentration were requested from the government agency’s laboratory in Jazan through an official letter from the faculty of Metrology Environment and Arid land Agriculture in King Abdul-Aziz University. Regarding area effects, dam lake surface area was estimated from high-resolution satellite images and cross referenced to the dam lake level in order to estimate the water volume in the dam lake. According to Eng. Walled, the operation coordinator at Baysh Dam, the water level of the dam is kept within controlled rang which is lower than 110 m (on the dam’s meter) in order to be prepared with unexpected recharge follow during winter season. Water surface effects identification processes were exercised with low data about the dam lake inflow, evaporation rate and out flow. The infiltration rate was neglected due the rocky bottom of the lake. Baysh Dam’s water quality were analyzed for seasonal variation using a satisfactory forecasting model. Monthly satellite data were used to meet the time series analysis requirements. A satisfactory model was implemented for reliable water quality and quantity forecasting within the designated sturdy area. The change in surface area has a clear effect on the Chlorophyll values, but has inverse relation with the lake’s turbidity The information of water quality data, in this research, gives a unique opportunity to analyze and examine the application of remotely sensed satellite data and that leads to a reliable and faster way to monitor the water quality in Baysh dam lake.
