The Existing Condition

Groundwater-Surface Water- Interactions


The analysis of the seasonal variations of groundwater and river water levels represents the conceptual model of the sand river aquifer system and the respective hydrological processes in dry season and flooding season. groundwater discharges into the river throughout most of the dry season. revealing the high permeability of the aquifer, groundwater levels are higher than the river level throughout the dry season. This means that harmful substances in groundwater are very easy to contaminate river water during dry periods. Water level rise during the flood season is extremely fast but temporary.Recharge occurs through quick infiltration from flood waters into very permeable sands, which are directly linked to the natural discharge of the sand river aquifer system to sustain the groundwater-surface water interaction after the rain season. However, after a long-term drought, the weathered sediment is easily washed away by the speed of the water flow, causing the flow and precipitation in the dry season, resulting in the depth of the river gradually becoming shallower in the next drought period,
