SWS comprise of various intelligent well and sensor configurations for different hydrogeological aquifer conditions. They can be combined for aquifer storage, (treatment), and recovery (AS(T)R), managed aquifer recharge (MAR), and various water reuse options including rainwater harvesting or treated waste water usage. To date, pilot SWS are implemented in the Netherlands, where they demonstrate highly beneficial applications for the above-mentioned purposes. This report presents the technology transfer to other coastal regions by utilising a participatory co-design approach with key stakeholders and institutions. The methodology developed mainly consists of two missions, which were applied to four target regions: Brazil, Mexico, Vietnam, and Cyprus. In these regions stakeholders were identified, framework conditions were assessed, and public events and project development workshops were conducted aiming to adapt the technology and implementation approach to the specific local requirements. General drivers and barriers were identified for institutional, political, legal, and socio-economic aspects. The report provides an outline of general implementation concepts, region-specific prerequisites, and ideas for follow-up projects.","PeriodicalId":354216,"journal":{"name":"Journal of Water Security","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115895035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, because of unequal demand of electricity during the day large hydropower plants are adapted to work in hydropeaking regime, which causes rapid water level and discharge fluctuations and has impact on the environment. To assess the extent of this impact in this study 2D numerical hydrodynamic modelling was carried out to reveal the dewatered or flooded stream channel areas at the Nemunas River downstream Kaunas Hydropower Plant. Such estimation of dewatered or flooded areas, considering different operating modes of hydropower plant, was carried out for the first time in Lithuania. It was revealed that largest areas are flooded when Kaunas hydropower plant starts its operation with two and four turbines and accordingly are dewatered when the plant stops such operations. During this study the impact of water level and discharge fluctuations on river ecosystems was not analysed, however the obtained results will be the initial data for more detailed assessment of fish habitats quality under impact of hydropeaking.","PeriodicalId":354216,"journal":{"name":"Journal of Water Security","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114283991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water samples were randomly collected from the groundwater and surface water sources across the study area. Samples were analyzed for physical (temperature, pH, electrical conductivity and turbidity), chemical (hardness, chloride, ammonia, and nitrate), and microbiological ( E. coli and total coliform bacteria) parameters using standard methods. The results demonstrated that the water samples were contaminated mostly with E. coli and total coliform (TC) bacteria. The bacterial population enumerated for E. coli (100 CFU/100 ml) and TC (300 CFU/100 ml) exceeded the National Drinking Water Quality Standard (NDWQS). Physical and chemical parameters analyzed for temperature, pH, conductivity, hardness, chloride, ammonia, and nitrate were within the acceptable limit of the NDWQS. However, the turbidity and ammonia was 34.6 NTU and 3.6 mg/l, were within the maximum values recommended by the NDWQS. This study exhibits that the groundwater and surface water quality of Bhaktapur district is contaminated with E. coli and TC bacteria hence, is vulnerable to drink. The water contaminated with bacteria ( E. coli and TC), presence of ammonia and turbidity more than the limit of NDWQS may pose health risks and cannot be accepted for drinking purpose without purification following appropriate scientific methods.","PeriodicalId":354216,"journal":{"name":"Journal of Water Security","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122853273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimizing the border width under varying soil moisture contents prior to irrigation was attempted. The border of length 25 m required 30.2 minutes (min) to 78.1 min for irrigation for a fixed cutoff length of 15 m. The water front advance time up to cutoff length was 10 min and 27.3 min for border widths varying from 2 to 5 m; respectively corresponding to the selected stream discharge of 1.5 l/s. The water front advance time was inversely proportional to the initial soil moisture contents. The travel time to cutoff point of 15 m for three soil moisture contents namely q 1:14.2, q 2:16.5 and q 3:17.2%; varied from 10.0-11.7 min for the border size (width) of 2.0 m, 14.0-15.6 min for the border size of 3 m; 20.0-23.4 min for the border size of 4 m whereas, it took 24.5- 27.3 min for 5 m border size. The best border size was identified as 4 m without any yield penalty. The effect of the stream discharge was not pronounced based on yields. Due to uniform cutoff ratio there was no significant difference in the amount of water use. Hence, the border size of 4 m was rated the best.","PeriodicalId":354216,"journal":{"name":"Journal of Water Security","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129181204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long Island (LI), New York, rests on a system of aquifers created by prehistoric glacial activity. These aquifer systems are the only source of drinking water for LI. Water quality issues are pervasive in the region due to nitrate pollution, caused by antiquated septic systems in much of the Island, as well as the prevalence of environmental clean-up sites. Using the Watertraq database, we searched for levels of select compounds that were present in wells above acceptable levels on LI. We then collected demographic data from the U.S. Census, including income, ethnicities, poverty levels, number of children, senior citizens and renters for towns in parts of two counties on LI to determine whether there was a relationship between the presence of above standard levels of compounds and income. Using an Ordinary Least Squares (OLS) regression we found a statistically significant negative impact (at the p < 0.01 level) of income on the presence of contaminants in untreated water. In other words, the lower the income of the region, the greater the chance that above standard levels of volatile organic compounds were present.","PeriodicalId":354216,"journal":{"name":"Journal of Water Security","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126246408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapidly growing population in these towns has put increasing stresses on limited water resources. The inverse relationship between supply and demand of water has created challenges to the water security in these towns. In the absence of elected local government, decision making processes, including the management and governance of water at local level were directly affected. There were some unanswered questions – who are the leaders? who sets agendas? How do they formulate and implement strategies and make decisions? This paper aims to analyse the context of water governance in rapidly urbanising small town in Nepal, focusing on actors and institutions. Primary data were collected through semi-structured interviews, focused group discussions and key informant surveys from Dhulikhel municipality and its upstream communities. This paper argues that the local level water governance practices in rapidly urbanising small towns in Nepal are still evolving. During the political transition and vacuumed local jurisdictions, the real decisions to manage and govern water were made in an informal way. The formal course of making decisions by authorised actors and institutions has been curtailed significantly.","PeriodicalId":354216,"journal":{"name":"Journal of Water Security","volume":"6 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132581636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
