The importance of rainfall in arid and semi-arid regions is more apparent. Due to the important role of rainfall trend assessment in the proper management of water resources, in the present study, Khorasan Razavi province, the second-most populous province of Iran located in the northeast of the country, for this purpose was studied. Currently, this region is facing water shortage problems. In this study, the non-parametric Mann-Kendall method was used to evaluate the annual rainfall trend over a thirty-year period from 1989 to 2019. On the other hand, Sen's slope estimator method was used to determine the magnitude of the rainfall trend in the studied synoptic and rain gauge stations. The results showed that the root of water shortage problems is not due to drastic changes in rainfall. Therefore, water shortage problems in Khorasan Razavi province are mainly due to a lack of proper management (i.e., mismanagement). The present study, by examining the rainfall trend using an appropriate framework, tried to take an effective step towards improving the management of water resources in the northeast of Iran.","PeriodicalId":39478,"journal":{"name":"Journal of Water Law","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80991460","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}

Were analyzed the variables temperature, pH, total dissolved solids, electrical conductivity, DO, BOD, ammoniacal-N, nitrite-N, nitrate-N, phosphate, sulfate and total hardness in four sampling campaigns in the year 2011. This amazon rivers presented physicochemical characteristics well heterogeneous, but similar behaviors for the variables pH, temperature and DO in the extensions evaluated, that is, increase in the source-mouth direction, with variations from 4.77 to 7.33 and 5.51 to 7.3, 25 to 31°C and 27 to 32°C and from 4.4 to 7.98 mg.L-1 and 1.17 to 6.55 mg.L-1 for the Arienga and Murucupi rivers respectively. In addition to these characteristics, the Arienga River also presented an increase for ammoniacal-N, nitrite-N, nitrate-N and hardness in the dry period, with variations from 0.014 to 6.336 mg.L-1, 0.005 to 0.334 mg.L-1, 0.009 to 4.818 mg.L-1 and 1.146 to 14.389 mg.L-1 respectively. In general, Murucupí River presented different physicochemical characteristics that are coherent with the local scenario, where the launch domestic effluents and the environmental impacts caused by industrial waste are visible and recurrent respectively.","PeriodicalId":39478,"journal":{"name":"Journal of Water Law","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77628161","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}
