- 2014. Groundwater and river water interaction to solve water shortage: a case from Tasikmalaya, Indonesia. PeerJ PrePrints 2:e720v1 https://doi.org/10.7287/peerj.preprints.720v1
Water shortage is a common problem in the high density settlement along the riverbank of Ciromban and Cibeureum River, Tasikmalaya, as the quality of the water also decreases. One of the solution is to maximize the use of river water. This study aims to investigate the interaction between river and groundwater along the riverbank as a function of land use impact. A river water and unconfined groundwater level mapping has been conducted to make water flow map, assuming both waters are in the same flow system. Physical parameters, temperature, TDS, and pH were measured at each stations to understand water characteristics. Based on observations at 50 dug wells and 12 river stations on July-August 2014, a close interaction between both water bodies has been identified with two flow systems: effluent flow (or gaining stream) at Cibereum river segment and influent flow (losing stream) at Ciromban river segment. Physical parameters show a high correlation in temperature, pH, and TDS. Hence, further evaluation from health point of view should be taken before using river water as raw water supply in Tasikmalaya area.
The very early part of this work has been presented as an abstract in the International Conference on Math and Natural Sciences (ICMNS), Institut Teknologi Bandung, in November 2014. Up to this point, we have developed the abstract with some new and additional data for further analysis.
