Bathymetric Mapping for Lake Hardibo in Northeast Ethiopia Using Sonar
Year: 2012
Type: article
Abstract: Lake Hardibo is a remarkable feature in the northeast Ethiopian highlands, with a rich endowment of resource values that need a series of scientific studies. This study adds multi‐temporal bathymetric information on the lake, which is of paramount importance, to indicate environmental changes and understand the effect of land processes on hydrology and sediment development of the lake and its basin in the future. Physical parameters, including depth, volume, area, width and length, were derived. The maximum depth measured was 65.20m, located almost at the geographical centre of the lake. A contour map, composite map and three‐dimensional map were produced. Plot profile curves were drawn. These findings can provide valuable information for lake protection initiatives and can be utilized for various water related resource management systems and environmental impact assessment studies. The bathymetric survey was carried out using a combination of the SonarLite Portable Echo Sounder and Global Positioning System (GPS), to generate XYZ hydrographic data points. Surfer 8.01 and ArcGIS 9.3 computer software were used to finalize data evaluation.
