“…Based on these results, this model is suitable for use in simulations of hydrology in the Gilgel Abay watershed. Including the modeling carried out in the Al-Adhaim, Northern Iraq, watershed, the results of R 2 are quite good at 0.92 [18,30]. Similarly, Barbosa [12] has seven different formulas to investigate hydrological performance with the HEC-HMS method: MAE, RSR, RMSE, NSE, R 2 , KGE, and PBIAS, which finally succeeded in obtaining the conclusion that the HEC-HMS model can represent hydrological processes on the distribution of watersheds investigated effectively, efficiently, and with good accuracy.…”

The amount of rainfall can be used to estimate the runoff that enters a reservoir. Runoff is influenced by land use, and soil type greatly affects the amount of runoff that will occur. This study discusses the development of a hydrological model with the application of the Hydrologic Engineering Center (HEC-HMS) in the Karangmumus watershed using soil data that has been verified in the field and divided into soil zones based on soil permeability testing in the laboratory. With the help of Geographic Information System (GIS) and Geospatial Hydrological Model (HEC-GeoHMS) applications, it is possible to identify the flow of the Karangmumus watershed and the Lempake Dam in Kalimantan by simulating the rain runoff process. The hydrological model was developed in the HEC-HMS by recording daily rainfall events from 2009 to 2019. With a daily period, then, the zoning soil type data was entered based on the results of soil permeability testing with the help of the application of the soil conservation curve method (SCS-CN), then discharge transformation, and calculation of water loss, including routing with Muskingum and SCS-Hydrograph applications. Based on the distribution of the CN value, the theoretical runoff is calculated and then calibrated with the observed discharge in 2017 and 2018, and then validated with the observed discharge in 2019, showing good results with a coefficient of determination between 0.89 to 0.92.

“…This provides richer information about the parameter uncertainties and allows for more robust modelling of the δ 2 Hδ 18 O covariance. Because of these advantages, the Bayesian approaches have recently been popular for solving water isotope problems (e. g. Putman et al, 2019;Arellano et al, 2020;Torres-Martínez et al, 2020;Zhang et al, 2020;Kang et al, 2022;Zaryab et al, 2022;Mao et al, 2023). The full benefits of using BLR can be found in Klauenberg et al (2015).…”

Stable isotopes, $\delta^2$H, $\delta^{18}$O, and d-excess, are valuable tools as natural tracers of diffusion processes and phase changes in the global hydroclimatological cycle. The Indonesian Maritime Continent (IMC) is an archipelago area surrounded by very warm waters which induce convective activities as the primary heat source driving global atmospheric circulation. Given the central role of IMC in this hydroclimatological cycle, comprehensive study and data collection on the stable isotopes of precipitation in this region is crucial.In this study, we collected monthly stable isotope data from 62 stations spread throughout the Indonesian archipelago from September 2010 to September 2017. We cleaned the data and conducted quality control activities by comparing the Local Meteoric Water Line (LMWL) to previous studies in a similar climatic region. We shared these data openly on our GitHub repository, making them easier to update and interact with users in the future.

“…The Piper diagram has not been disturbed by human subjective factors [27], and the distribution of water samples is shown in the diagram. This is a common method for identifying the main ion composition of water chemistry [28,29]. Piper plots are made using the main ion data for groundwater in the study area (Figure 2).…”

“…δD and δ 18 O in groundwater are predominantly determined by atmospheric processes and can be used as natural tracers for groundwater sources [30][31][32]. δD and δ 18 O in groundwater are controlled by local hydrometeorological factors, including the origin of the water vapor mass, re-evaporation during rainfall, and precipitation seasonality [29,33]. Yin et al concluded that the local atmospheric precipitation line in the northern Ordos Basin is δD = 6.45δ 18 O − 6.51 with R2 = 0.87 [34].…”

The exploitation of groundwater in arid and semi-arid areas, especially in basins where groundwater is intensively exploited, is likely to have adverse effects on the originally fragile ecological environment, which also greatly alter the hydrogeochemical evolution process. Over-abstraction of groundwater in the Haolebaoji watershed of the Ordos Basin located in the semi-arid regions has led to a series of changes in the groundwater system, which has attracted considerable attention from environmental protection organizations. However, the origin and geochemical evolution of groundwater in the Haolebaoji watershed have not been revealed. In this study, the Haolebaoji watershed is selected as the typical study area to investigate hydrogeochemical evolution under the intensive groundwater exploitation. Groundwater samples were collected and tested for major ions and stable isotopes (δ18O, δD). Various approaches including the ion proportional relationship diagram, chlor-alkali index, saturation index, Gibbs diagram, and principal factor analysis were used to reveal the hydrogeochemical processes regulating the groundwater geochemistry. The groundwater in the study area is divided into five hydrochemical types according to the Piper diagram. It was found that the chemical composition of groundwater in the study area is mainly controlled by the dissolution of calcite, dolomite, gypsum, and halite. The cation exchange intensity gradually increased with the flow of groundwater from the recharge to the discharge area. Rock weathering plays a controlling role in the formation of groundwater geochemistry, but it is also controlled by evaporative crystallization in some runoff and discharge areas. Groundwater is predominantly recharged by modern local atmospheric precipitation, and deep wells receive water supply during cold periods. The study findings provide important information for the development of sustainable groundwater management strategies for the Ordos Energy Base.
