Two major applications have been used: Treating sludge streams from midsized and large wastewater treatment plants and for industrial wastewater streams containing high concentrations of organic carbon. This paper presents the status of anaerobic digestion of sludge streams in municipal wastewater. The paper highlights both the potentials and limitations of the technology. Further the alternative or complementing HTC-technology is presented and analyzed. The constraints, limitations and options for the reuse of processed municipal sludge is accordingly pointed out. Our usage of water is found more and more complex, along with the addition of a number of synthetic agents, such as pharmaceuticals and other complex polluting agents we find that the traditionally acknowledged sludge treatment stabilization methods are not sufficient. The paper points out that the anaerobic digestion may be combined with for instance the HTC-process. In a longer perspective the HTC may even replace the current anaerobic digestion. However, the HTC-technology will raise further interesting questions: The important points that need further investigations are inter alia: 1) To further clarify the quality of reject water from the hydrochar, with respect to rest pollutants. 2) To evaluate to what extent the HTC process may become a feasible way to disintegrate pharmaceutical remains found in municipal sludge. 3) How to further enhance the ways to recover raw materials from the hydrochar, such as phosphorus and carbon. Nethertheless, the process may allow for some very promising pathways within the future municipal sludge management.","PeriodicalId":127298,"journal":{"name":"Water: Ecology and Management","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128788260","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}

We present a simple, low-cost, and robust approach for forecasting monthly and yearly streamflows during the current hydrological year, which is applicable to headwater catchments. The procedure innovatively combines the use of well-known regression analysis techniques, the two-parameter Gamma continuous cumulative probability distribution function and the Monte Carlo method. Several model performance statistics metrics (including the Coefficient of Determination R2; the Root-Mean-Square Error RMSE; the Mean Absolute Error MAE; the Index of Agreement IOA; the Mean Absolute Percent Error MAPE; the Coefficient of Nash-Sutcliffe Efficiency NSE; and the Inclusion Coefficient IC) were used and the results showed good levels of accuracy (improving as the number of observed months increases). The model forecast outputs are the mean monthly and yearly streamflows along with the 10th and 90th percentiles. The methodology has been successfully applied to two headwater reservoirs within the Guadalquivir River Basin in southern Spain, achieving an accuracy of 92% and 80% in March 2017. These risk-based predictions are of great value, especially before the intensive irrigation campaign starts in the middle of the hydrological year, when Water Authorities have to ensure that the right decision is made on how to best allocate the available water volume between the different water users and environmental needs.","PeriodicalId":127298,"journal":{"name":"Water: Ecology and Management","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133940562","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, it is difficult to use to monitor the ongoing drought characteristics because it cannot be expeditiously related to precipitation deficits. It also does not provide information regarding the drought risk nor the temporal evolution of the droughts. By using the SPI, a copula-based Continuous Drought Risk Monitoring System, CDRMS, was developed aiming to monitor the droughts, including the risk of having a drought event as the rainy season advances. In climates with very pronounced rainy seasons, the absence of precipitation along the same is the fundamental booster of droughts. After presenting the CDRMS, the paper describes its application to Mainland Portugal, which showed that the system has an increased capability of anticipating the drought risk by the end of the rainy season as new precipitation records are known. The good performance of the system results from the ability of the copula to model complex dependence structures as those existing between precipitations in different time intervals. CDRMS is an innovative and user-friendly tool to monitor the precipitation and, consequently, the drought risk, allowing to anticipate mitigation and adaptation measures or even to issue alarms.","PeriodicalId":127298,"journal":{"name":"Water: Ecology and Management","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121387099","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}
