“…Additionally, the topography and geology of the surrounding landscape play a crucial role in influencing water flow, thereby impacting river water levels (Schumm and Spitz, 1996;Detty and McGuire, 2010;Grant, 2012;Rinderer, Meerveld van and Seibert, 2014;Trevisan et al, 2020;Dai et al, 2021). Notably, the topography of the study area, characterised by a slope from the Nida River side to the Smuga Umianowicka branch, contributes to the abnormal increase in water level observed at the Smuga Umianowicka branch during periods of heavy rainfall.…”

The study area of the Nida valley was examined to investigate variations in groundwater and surface water levels, as well as the interaction between them. In the valley, there were three branches. The two actives were the Nida River itself and the Smuga Umianowicka branch while the Stara Nida branch was dry during the measurement session. Over a 12-month period from June 2021 to June 2022, 7 monitoring points were equipped with piezometers, comprising 5 groundwater points and 2 surface water points. The monitoring frequency was set to 30 minutes. The results of this research indicate that there are significant differences in the water level at the same observed point at different times. This study demonstrates seasonal changes in both surface water and groundwater levels with higher levels in autumn and winter and lower levels in spring and summer, which are closely tied to the changes in meteorological conditions during the research period, such as precipitation and air temperature. The study results also indicate that during summer and winter at the Nida River and its riparian area, losing stream is the primary process occurring in the studied reach. Conversely, during autumn and spring, the main process is gaining stream. At the human-maintained Smuga Umianowicka branch and in its riparian area, losing stream is the main process during summer and autumn, and gaining stream is the main process during spring. During winter, losing stream and gaining stream processes can occur simultaneously, and neither process takes place mainly.

“…Daerah kajian berada di lereng Gunungapi Kawi Malang dengan topografi bergunung dan lembah. Kondisi airtanah bebas sangat dipengaruhi oleh topografi (Dai et al, 2021). Pendekatan hidrogeomorfologi yang digunakan pada kajian mempertimbangkan aspek geomorfologi dan litologi yang berpengaruh terhadap potensi airtanah, selain juga mempengaruhi proses aliran permukaan (runoff ), erosi permukaan, dan aliran sungai (Sidle & Onda, 2004).…”

This study aims to identify the potential groundwater in Jedong, Malang, East Java. The hydrogeomorphological approach is a suitable approach to describe the relationship between hydrological and geomorphological processes on and below the earth's surface. The survey of geoelectricity complements the hydrogeomorphological approach. It will give a better description of the groundwater conditions below the earth's surface. Based on the research, there are 2 hydrogeomorphological units in the study area, which are: Volcanic Foot Valley Unit and Volcanic Foot Ridge Unit. The best groundwater potential is in Volcanic Foot Valley Hydrogeomorphological unit, namely Awar-awar Valley and Cokro Valley. The valleys are dominated by gully erosion and landslides. They have surface deposits up to a depth of 7 meters, and lots of outcrops of breccia, pumice, and andesite boulders. The valley’s springs discharge between 56 - 198 m3/day. The average infiltration rate in the valley is 1776 mm / hour, with sandy soil material. The best aquifer consisting of sandy material is more than 10 meters in depth, based on the geoelectrical survey. Water in the aquiclude layer, cannot be exploited because it is breccia and tuff material. The Sawah valley cannot be exploited further because the groundwater potential is very low. This can be identified by the thick water outflow seepage. In the Volcanic Foot Ridge Hydrogeomorphological unit, the groundwater potential is also very small. Hydrogeomorphically, water will flow down the slope to the valley. It will reduce the infiltration rate. In general, the ridge area is only used for settlement, while the slopes are used for dryland agriculture. The geoelectric analysis results show that the groundwater potential is at a depth of more than 45 meters. This research’s results show that the combination of the hydrogeomorphological approach and the geoelectric use will provide a better description of the potential groundwater.

“…Moreover, several studies have demonstrated that employing terrain as a setting for top boundary conditions always result in high fluxes at the top boundary, which may exceed actual local precipitation or evapotranspiration. Some studies suggest that the prevalence of the Tothian pattern of nested groundwater flow systems may not be as widespread as previously assumed within the framework of idealized conceptual models (Dai et al 2021). In this case, mathematical simulations with specified head top boundaries assumed by simplified representations of topography may not depict real groundwater flow.…”
