Groundwater Condition

Opak River Basin is an area with high concentration of settlement. Generally, the settlement use groundwater as a water source. Variation of groundwater condition cause differentiation of water usage in some regions. There are two objectives of this research. First, to determine aquifer system in the research area and second, to calculate the groundwater potential in each aquifer system. To achieve these objectives, aquifer system is determined base on its geology and geomorphology, whereas groundwater potency is calculated by static and dynamic approach. As a result, show that the aquifer system in Opak River Basin can be distinguished into seven aquifer system. There are The Upper Merapi Aquifer System, The Middle Merapi Aquifer System, The Lower Merapi Aquifer System, Baturagung Range Aquifer System, The Aquifer System of Baturagung Range Foot Slope, Sentolo Hill Aquifer System and Sanddune Aquifer System. Among the seventh aquifer system, The Middle Merapi Aquifer System, The Lower Merapi Aquifer System and The Sanddune Aquifer System have high productivity. Sentolo Hill Aquifer System and The Aquifer System of Baturagung Range Foot Slope Aquifer have low productivity, whereas The Baturagung Range is categorized as non akuifer.

Abstract The Hanjiang River Basin serves as the water source for the Middle Route South-to-North Water Delivery Project. Droughts are not uncommon in this region and have affected the water supply directly. This study is designed to gain more in-depth knowledge of spatial and temporal drought variations in the Hanjiang River Basin, and the synchronization of drought variations in upstream and downstream regions of the Danjiangkou Dam. Compared with drought analysis in the upstream or the downstream, respectively, research shows the spatial difference between the upstream and the downstream clearly. The following conclusions can be drawn: Standardized Precipitation Indexes in the Hanjiang River Basin did not significantly decrease; droughts considered moderate or worse occurred most frequently in autumn and winter, but most rarely in summer; the cumulative probability of moderate to severe droughts was highest in October and December. Drought conditions in the upstream region varied in a fluctuating way. The upstream region has become increasingly wet since the turn of the 21st century, while the downstream region has become increasingly dry since the 1990s. The probability of synchronous droughts both upstream and downstream was only 9.8%.

Nueces River

Reliable water sources are central to human and environmental health. In south Texas, USA, the Nueces River Basin (NRB) directly or indirectly plays that important role for many counties. Several NRB stream segments are designated as ecologically significant because they serve crucial hydrologic, ecologic, and biologic functions. The hydrologically significant streams recharge the Edwards Aquifer, an essential water source for the region’s agricultural, industrial, and residential activities. Unfortunately, the semiarid to arid south Texas climate leads to large inter-annual precipitation variability which impacts streamflow, and as a consequence, the aquifer’s recharge. In this study, we used a suite of hydrologic metrics to evaluate the NRB’s hydroclimatic trends and assess their potential impacts on the watershed’s ecologically significant stream segments using precipitation and streamflow data from the National Climatic Data Center (NCDC) and Hydroclimatic Data Network (HCDN) respectively from 1970 to 2014. The results consistently showed statistically significant decreasing streamflow for certain low-flow indicators over various temporal scales, likely due to water rights diversions and minimal land use changes. This research could help decision-makers develop the necessary tools to manage water resources in south Texas, given the NRB’s significance as a source of water for domestic consumption and ecological health.

Gauging Station

Saguling reservoir is one of the three largest reservoirs in the Citarum River Basin. The water source of its reservoir originates from Upper Citarum river basin, with gauging station located in Citarum-Nanjung and local discharge from tributaries around the reservoir. The problem is there is no observation of local discharge from the tributaries, thus its potential is estimated. The purpose of this study is to analyze the potential of local discharge with the Hydrology Engineering Center-Hydrologic Modeling System (HEC-HMS) model. The HEC-HMS Rainfall-runoff method is used for calculating the potential of the local discharge that flows into Saguling resevrvoir. The parameters used in the model are deficit constant (loss parameter), linear reservoir (baseflow parameter), dan lag time (transform parameter). Rainfall-runoff model produced good calibration values for Citarum-Nanjung Gauging Station with R2 of 0.8 and the Nash-Sutcliffe efficiency (NSE) value of 0.788. The verification result carried out in Saguling reservoir gives NSE of 0.8343 and R2 value of 0.83. The simulation shows that the potential discharge from local river contributes about 21.64% of the total discharge that enters  into the reservoir with monthly dependable flow for power plants, Q80 and Q85 values at 8,23 m3/s and 5,69 m3/s, respectively. The average discharge of local rivers can generate electricity of 3.89 MW - 162 MW.Keywords: Local discharge, rainfall runoff, potential discharge, Saguling reservoir

Backpropagation Method

Water treatment plants (WTPs) in Kuantan river basin abstracts water from the blue water source, which is the Kuantan river. Therefore, by accounting the blue water footprint (WFb), the overall water consumption for all five WTPs  namely; Sungai Lembing, Bukit Sagu, Panching, Semambu, and Bukit Ubi can be obtained. In order to predict the value, Backpropagation method is the best method to be used due to the historical data obtained from the WFb accounting for all five WTPs above. The objective of this study is to predict the overall blue water consumption for water treatment plants located along Kuantan river basin using Backpropagation method in artificial neural network. In this study, WFb has been accounted throughout all water treatment plants by using reference from water footprint manual. Then, the WFb will undergo a series of testing using application in MATLAB software in order to predict the future value based on historical data from 2015 until 2016. As a result, the total WFb accounting obtained was 190,543,378.2 m3/day, while the total maximum capacity of the WTPs was 189,654,000 m3/day. Hence, the prediction value that kept increasing will not be able to cater the future demand due to unstoppable urbanization.

The 60-mile-long Delaware and Raritan Canal in New Jersey, USA, serves a major interbasin water source receiving water from the Delaware River and runoff from some S3 sq. miles of land in New Jersey discharging to the Raritan River Basin. Approximately 78 million gallons of water per day are withdrawn for treatment and distribution to soine 600,000 people. The water and the sediments contain some halogenated organic compounds. The study was that of the significance of these compounds in the water supplies. The sediments in the Canal are to be removed, in part, and disposal of the dredge spoils depends on the chemical pollutants.

Spatio-temporal change of land use and land cover from 1985 to 2005 in Chao River Basin, the important water source to Miyun Reservoir, was analyzed based on GIS technology. The results showed that woodland was the main land cover type in the basin, and then the arable land and grassland. During 1985-2005, the area of woodland increased, while the area of grassland greatly reduced. Changes of land use and land cover were more violent from 1985 to 1995 than that from 1995 to 2005. There were obvious regional differences in land use change in the basin. The conversion from grassland to woodland was the dominant process of LUCC in the basin, and this was relevant to the national ecological construction policies on water resources conservation.

 The Una River and its basin constitute an important water source for public supply in the municipality of Taubaté (SP, Brazil). The present work aimed to investigate biochemical markers of environmental pollution in the Una river basin using enzymes extracted from the kidneys, gills and brains of Astyanax bimaculatus, a fish commonly found in this basin. Tissue levels of superoxide dismutase (SOD), catalase (CAT), malate dehydrogenase (MDH), lactate dehydrogenase (LDH) and acetylcholinesterase (AChE) were determined in tissues of A. bimaculatus collected in water bodies localized at Fazenda Piloto of the University of Taubaté (P1), the Remédios municipal road (P2) and at a small lake near the neighborhood of Ipiranga (P3), all located in the municipality of Taubaté. The lowest activities of renal and gill SOD were found in fish collected from P2 and P3, respectively. Renal and branchial CAT, renal MDH and LDH, as well as the activity of cerebral LDH were not affected by collection site. The activities of brain MDH and AChE were higher in fish from P3 in comparison with P1. These results along with earlier published findings, indicate that the hepatic SOD and CAT, gill SOD and LDH, muscle MDH and brain MDH and AChE are sensitive to contamination in the environment and hence can be considered as good candidate biomarkers of environmental change in the Una River basin.
