With the continuous development and maturity of artificial intelligence (AI) algorithms represented by neural networks, meteorological departments are attempting to replace or compensate for traditional numerical models with statistical methods. This article designed an AI intelligent meteorological service platform to simulate what happens when people use it. Based on commonly used AI technologies in meteorological research, the temporal data algorithm mentioned in this article is used for prediction. This article selected the actual daily average water vapor pressure and daily average relative humidity data of three meteorological stations over the past 10 days for analysis. The maximum and minimum of the actual daily average vapor pressure for 10 days are 30.2 and 28.1 Pa, respectively, the predicted maximum and minimum values are of 30 and 28 Pa, respectively, and the maximum and minimum values of the actual daily average vapor pressure over 10 days of Cupertino are 30.4 and 28.4 Pa, respectively, which can prove the effectiveness of AI-based intelligent virtual imaging meteorological services.

The soil and water assessment tool (SWAT) is used for predicting integrated inflows into the Hatnur reservoir from the Burhanpur and Purna watersheds of the Upper Tapi River basin, while outflows are simulated using a rule curve. The influence of watershed complexities on hydrological model parameters and the watershed processes are investigated using extensive multisite and multivariable calibration (1998–2007) and validation (2008–2013) approaches, including sensitivity and uncertainty analyses. The sensitive parameters are related to curve number (CN), groundwater, slope, and main channel characteristics. The annual streamflow (m3/km2/mm of rainfall) in the Burhanpur watershed is 568.7, which is 4.2 times higher than the Purna watershed's streamflow of 136.2. The hypsometric analysis, areal rainfall, and flow duration curves revealed a substantially different streamflow pattern and a larger coefficient of variation in the spatial distribution of water balance components over sub-watersheds in the Burhanpur watershed compared to the Purna watershed due to diverse topographic features. The developed model would be useful for planning controlled releases from the terminal reservoir to mitigate hazards in the downstream reaches of the Tapi River basin.","PeriodicalId":23725,"journal":{"name":"Water Supply","volume":"85 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139200523","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}

This study calculates the crop water stress index (CWSI) for four irrigation regimes in semi-arid region, India. Plots 1, 2, 3, and 4 had soil moisture depletion of 50% (drip system), 25% (drip system), unregulated (farmer replicated flood system), and 50% (flood system) with irrigation. In this work, we examined the value of employing a portable infrared thermometer (IRT) to measure wheat canopy temperature (Tc) at two geographical locations. The IRT field of view is 51.28–5,128 cm2, or 10–100 cm from the canopy crown. The field of view change from 10 to 100 cm affects Tc and CWSI in the four irrigation treatments, ranging from 0.65 to 2.71% and 9.2 to 36.4%, respectively. The research found that increasing the IRT from 10 to 100 cm reduced slope by 5.7% and intercept values by 20.6% in lower baselines. The R2 for CWSI and soil moisture was 0.78 (10 cm) and 0.77 (100 cm). Drip-irrigated plots are more sensitive to IRT spatial resolution than flood-irrigated plots. The findings suggest that CWSI studies may benefit from specific sample methods for Tc evaluation.","PeriodicalId":23725,"journal":{"name":"Water Supply","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139218176","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}

They are also important for tracking lead or copper release in the distribution system before, during, and after a treatment strategy is in place. A major debate is whether to use test pieces of pipe harvested from the distribution system or to use conditioned new metal surfaces. Harvested and conditioned new test pieces were studied in multiple types of water systems using analysis of chemical scales, biofilms, and metals release data. It was found that both methods of testing are equally valid if procedures follow certain conditions: (1) apparatus configuration and operation are consistent, (2) properties of distribution system pipe wall accumulations are known, (3) dissolved and particulate metal fractions are determined, and (4) apparatus metal release data are correlated with residential data. The use of conditioned new test pieces, obtainable with relative ease, lowers corrosion control study costs, providing a tool for water systems of all sizes to select the most effective corrosion control strategy and to pro-actively track lead and copper release trends in the distribution system.","PeriodicalId":23725,"journal":{"name":"Water Supply","volume":"373 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139242496","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}

Nine famous aflaj systems in Oman were prioritized based on indicators including length, population, precipitation, discharge, quality, distance from the river network, cultivated area, and soil permeability. A snowball method for selecting participants was used, and a 28-item questionnaire was engaged to assess the relative importance of nine criteria when choosing the prior falaj. A scientific method is applied in a new case in this study to prioritize the aflaj for rehabilitation, and the method applied in this research enables to prioritize them to achieve the desired goal. The AHP method prioritizes the falaj Daris as the first ranking, based on the technical perspectives, with a relative value of 0.222.

The heterogeneity of the karst aquifer medium makes it vulnerable to external influences. Here, samples of surface water and groundwater in a typical karst groundwater system of Jinan (China) were collected in December 2021, and the sample data were analyzed to further elucidate the hydrogeochemical processes. Results showed that the predominant water chemical type is HCO3-Ca, with a lesser proportion of type HCO3 · SO4-Ca and SO4-Ca. The dominant water–rock interactions comprise the dissolution of carbonate minerals, gypsum, and halite and ion exchange. Dissolution/precipitation of calcite, dolomite, and gypsum determines the concentrations of Ca2+, Mg2+, HCO3-, and SO42-. In terms of spatial distribution, the indirect and direct recharge areas are dominated by calcite dissolution, followed by dolomite dissolution, and are prone to ion exchange. The hydrogeochemical formation mechanism of the discharge area is more complicated by other hydrochemical processes and anthropogenic activities. These results provide guidance for global karst groundwater resource management and pollution prevention.","PeriodicalId":23725,"journal":{"name":"Water Supply","volume":"115 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139245272","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 short, low utilization rate and severe pollution of water resources are increasingly becoming important reasons hindering sustainable social development. To relieve environmental stress on water resources and promote stable socio-economic development, this article combined input–output models to analyze water resource utilization and development and classify economic benefits. Based on this, an in-depth study was conducted on the economic benefits of water resources. Taking Hubei Province as an example, from the perspective of industrial structure, an empirical analysis was conducted on the water use benefits of various industries through input–output of water resources. The results showed that the mechanical industry and the transportation industry had the highest relative output coefficients, reaching 12.17 and 15.21, respectively. According to the results, the economic benefits of water resources in the secondary and tertiary industries of Hubei Province were relatively ideal. In practical development, industry-leading advantages could be utilized to optimize water resources management, innovate water use models and technologies, promote the improvement of agricultural water utilization rate and thus promote sustainable development of water resources.","PeriodicalId":23725,"journal":{"name":"Water Supply","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139245526","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}

According to this aim, the water system was equipped with remote sensing (RS), networked sensors, advanced modems, and data loggers. The study showed how to control hydraulic parameters by the Internet of things and RS. The higher retention time led to the probability growth of rebar oxidation in concrete in the presence of chlorine and increased the possibility of water loss. This work also showed how to decrease the probability of water leakage in reservoirs. The computational fluid dynamics analysis results showed that the two baffles case led to the emergence of three eddy currents in the three zones created. The better fluid interpenetration caused the reduction in retention time. In the areas where the vortex was formed, the number of eddy currents decreased and the retention time increased. Regression analysis showed that the P value was 0.998 and 0.977 for the inlet flow and outlet flow for the reservoir, respectively (two baffles case perpendicular to the flow direction). The curve estimation showed that the power function had a suitable correlation on the scatter diagram and with the best curve fit.","PeriodicalId":23725,"journal":{"name":"Water Supply","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139256064","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}

This article aims to plan the two objectives of water supply and reducing the environmental effects of nitrates in rice cultivation and analyzing the maximum and minimum benefits. By modifying the methods of fertilization and water distribution, the amount of production can be gradually increased by taking into account the harmful effects on the environment. Water and nitrate have a synergistic effect on the growth of paddy rice. However, the amount of runoff that is affected by nitrates is directly related to the pollution of aquatic environments. The results confirmed the correlation between nitrate concentration and production and reported the reduction of its negative effects depending on the management of inflow and outflow to rice fields. Changing the outflow according to the fertilization time and the inflow rate is an effective solution in the fertilizer nitrogen uptake and reducing the nitrate concentration in surface water sources in the long term.","PeriodicalId":23725,"journal":{"name":"Water Supply","volume":"22 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139255840","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}

Field studies were conducted over two seasons (2017–2019) to evaluate the effects of drip irrigation (DI) and surface irrigation (SI) methods coupled with three irrigation regimes on agronomic parameters of carrot crops. Irrigation regimes consisted of water replacements of cumulated crop evapotranspiration (ETc) at levels of 100% (I100), 70% (I70), and 40% (I40) when the readily available water in I100 treatment was depleted. Results showed a reduction in carrot yield by 13–22% and 22–32% with I70 and I40 treatments compared to I100, respectively. Yield is affected by the irrigation method with a reduction of around 6–7% under the surface method for both years. The water productivity (WP) was found to significantly vary among regimes and methods, where the highest values were observed for the I40 regimes and drip method. Drip and I100 irrigation techniques seem to optimize carrot production.
