Model of Ground Water Elevation around Mud Reservoir in Coastal Area of Porong Sidoarjo

Abstract:

The previous research got several difference curves of the water level in the large scale from the coastal line perpendicular around 20 km to the land direction over the reservoir area . These curves were caused by both variation of precipitation and sea water level fluctuation of tide. The purpose of this research is to estimate the physical characteristics of water level of ground water around the mud reservoir. The numerical modeling of D-F theory is has be implemented. The idea is to take the solution of discharge equation for well from the ground water level. The model includes the shape of the infiltration mud-volcano from the reservoir to the natural water level of ground water. The field records will be used to make confirmation and validation. The result of this research is to support the result of the previous research, the level of water table around mud reservoir about 2 km perpendicular to the coastline direction (East direction) is full-filled by mud-volcano. On the other hand, for the opposite direction i.e.West direction from mud reservoir about 1.5 km is also full-filled by mud-volcano. The error between numerical model and field records is around 1%.
