Abstract

Fllod often occur if the rainfall is high, the flood-affected areas are downstream areas around the Musi Watershed of Kepahiang. The purpose of the study was to find out the characteristics of the physical parameters that affect the potential for flooding in the upstream river and the Musi Watershed. The method used are in situ measurement and laboratory analysis. The results of research, the characteristics of the river's physical parameters after the rain, the river flow discharge is 14.50 m3/s, floating sediment discharge 1.13 kg/s, bottom sediment discharge 43 x 10-4 kg/s, and total sediment discharge 113 x 10-2 kg/s. While the condition is not raining, the river flow discharge is 5.37 m3/s, the floating sediment discharge is 0.30 kg/s, the bottom sediment discharge is 32 x 10-4 kg/s, and the total sediment discharge is 30 x 10-2 kg/s. The dominant sediment texture is sand, clay and silt with a grain size of 1.4 mm - 600 µm. The river bathymetry has a lower elevation at the confluence of the Gegasan River and Lanang River which causes the river currents to reverse, if there is an increase in rainfall it will cause flooding in the area around the river.

Abstract

The city of Bengkulu is the capital of Bengkulu Province, has a lake called Danau Dendam Tak Sudah (DDTS), which is located in a strategic area due to its potential underground water resources. The purpose of this study was to determine the distribution of aquifers around DDTS, in Surabaya Village, Sungai Serut Subdistrict, Bengkulu City through the geophysical method of Vertical Electrical Sounding (VES) with Schlumberger Configuration. VES measurement points were taken at 21 points. This study was conducted in a residential area to determine whether the subsurface aquifer is connected to water in DDTS. Data acquisition used the MAE X612-EM VHR Multi-Channel Resistivitimeter Geoelectric tool. The results of data acquisition in the field were then processed using Progress, Strater, IP2win and Surfer software. The interpretation results show that the resistivity value, depth and thickness vary as well as the existence of 2 - 5 layers as the geological structure and characteristics of the local lithology with a resistivity value of 2 - 19 Ω.m is groundwater, resistivity value of 19 - 30 Ω.m clay flake, resistivity value of 30 - 70 Ω.m clay, resistivity value of 70 - 100 Ω.m top soil and resistivity value of 100 - 150 Ω.m sandy gravel. Shallow aquifers are estimated to be at a depth of < 20 m, while the deep aquifers are located at > 25 m below the surface and have a thickness of 2 to 78.5 m.
