| Abstract | Water resources study of the Nang Han Lake in Sakon Nakhon was carried out. Hydrology of the catchment area was studied in evaluating the amount of the inflow to the lake which causes flooding over the area around the lake. The amount of sediment deposited in the lake was measured from sounding survey and compared it with the bed contour of the map prepared in 1942. Outflow routing was performed for checking the capacity of the existing outlet. Soil samples around the lake and sediment samples in the lake were
collected and analyzed to examine their physical and chemical properties. Results of the study indicate that large amount of inflow comes to the
lake during the rainy season and the outflow from the lake is limited by the size of the outlet gate. In the dry season the lake water is retained to be used for water supply of the town and fish culture. When the rain
reaches its peak in the rainy season, the lake water cannot be released on time due to the limiting capacity. of the outlet gate which result in flooding of the land area around the lake. The average depth of the sediments is approximately 24 cm after a 40 years period. Heavy deposition is found
in the middle channel of the lake in the vicinity of the outlet gate. From the analysis of the soil samples and sediment samples it was found that the
major constituents of the sediments are derived mainly from the erosion of the soils around the lake. |
