To this end, the climate data were first assessed by the Mann–Kendall test to determine trends. Then, changes in temperature and precipitation were simulated using HadGEM2-ES in the Long Ashton Research Station Weather Generator (LARS-WG) under two representative concentration pathways (RCPs) of 2.6 and 8.5 over the periods 2021–2040 and 2041–2060. CROPWAT8 was used to calculate the crop water requirement and irrigation hydromodule, and the turnout flow in the considered canal was calculated next. Finally, the canal was simulated and assessed. The results showed that the maximum temperature, evapotranspiration and turnout flow increases are 3.7°C, 1.45 mm/day and 39 L/s, respectively, related to the base timescale. Additionally, the adequacy performance decreased to 0.768 from 0.986, leading to a maximum extra water requirement of 15.1 million m3/year in the Aghili east canal under a pessimistic scenario.","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"961-973"},"PeriodicalIF":1.6,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139621699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the suitability of land for irrigated sugar cane cultivation and crop water requirements in the Kuraz Irrigation Scheme, Ethiopia. To accomplish this, the geographic information system–analytical hierarchy process (GIS–AHP) tool combination was employed to identify land suitability classes and aid in decision-making using various factors, such as soil pH, texture, temperature, rainfall, land use–land cover and slope. The AquaCrop model simulated the current and future scenarios for biomass, canopy cover, yield, maximum evapotranspiration and evapotranspiration water productivity for sugar cane crops. AquaCrop was calibrated for irrigated sugar cane in the 2015–2016 crop season, and the results showed that most of the study area is highly suitable for sugar cane cultivation. Highly suitable areas cover 28%, moderately suitable areas 38%, marginally suitable areas 21%, and unsuitable areas 13%. The findings indicate the potential for expanding sugar cane cultivation and increasing yields and profits. However, it is crucial to consider the potential environmental degradation caused by water usage and soil degradation resulting from agricultural expansion. Furthermore, the social implications of expanding sugar cane cultivation should also be considered, including labour practices and the possible displacement of local communities.","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"1080-1101"},"PeriodicalIF":1.6,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139626904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a suitability analysis of irrigable areas for irrigation using spatial techniques. The focus of this paper was to examine regions that may be viable for irrigation for four small reservoirs constructed under the ‘One Village One Dam’ (1V1D) initiative. The thematic factors used were distance to water, soil type, soil depth, slope, pH, electrical conductivity, hydraulic conductivity, land use–land cover, organic carbon and organic matter. The land cover was classified using high-resolution imagery from SAS Planet because of the small land size. The pairwise ranking found soil type to have an overall higher weight of approximately 15% and electrical conductivity to have the lowest weight. The highly suitable areas were found very close to the dam, and the permanently not suitable areas were located at the far end of the dam. From the area computation, it was found that the highly suitable regions in Kataa, Degri, Napaadi and Zansibulga were 10.52, 55.41, 1.01 and 3.77 ha, respectively. In conclusion, it was found that the majority of irrigable land was within the marginally to highly suitable class.","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"1030-1051"},"PeriodicalIF":1.6,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139446285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We applied Mann–Kendall, linear regression and Pettit tests to statistically determine trends of SWRs in terms of water level, total water volume and rainfall in 1996–2020. The findings show that high water level trends decrease significantly after 2011, and this reduction has been due to climate variability and dam development upstream of the Mekong River. Moreover, rice yield data analysis from 1996 to 2020 indicated a decreasing trend in the yield of the winter–spring rice crop in the An Phu district of An Giang Province after 2011. Our interviews with 33 water experts and 90 local farmers revealed 80% agreement that the decline in water resources has affected rice yield.

The objective of this study was to evaluate the water requirements and WUE of banana, lemon and mango crops in the irrigated perimeter region of Jaíba using satellite images and meteorological data. Landsat 8 satellite images from 2020 and 2021 were used to estimate the local Kc of these crops. Three methodologies for estimating local Kc were adopted: METRIC, NDVI and NDVI 2. The Kc NDVI method stood out when compared with the standard method (FAO Bulletin 56), with RMSEs of 0.11, 0.16 and 0.20 for banana, lemon and mango, respectively, showing the potential of this methodology. The overall average WUE values for banana, lemon and mango crops were 2.19, 1.58 and 1.58 kg m−3, respectively.

This study revealed the effects of biochar application on the physical and mechanical properties of a clay-type soil at different irrigation levels. Soil was treated with three levels of biochar application: B0 (0 t ha⁻¹), B1 (25 t ha⁻¹) and B2 (50 t ha⁻¹), and three levels of irrigation: T0 (1.2 pan evaporation Ep), T1 (1.0 Ep) and T2 (0.8 Ep). The results indicated that other treatments reduced the soil bulk density compared with the control treatment (CK) (B0T1). Compared to CK, the highest reduction in soil bulk density was 18%. Irrigation did not improve the soil bulk density and porosity at the same biochar application in the short term. Biochar enhanced the stability of the soil aggregates. Compared to CK, the largest MWD (mean weight diameter) was enhanced by 9%. The addition of biochar and decreasing irrigation could decrease soil cohesion. The addition of biochar and increasing irrigation could increase the soil internal friction angle. The soil cohesion first increased and then decreased as the soil water content increased. According to the fitting formula, the soil cohesion was found to be minimum at B2T2, which was a decrease of 39% compared to B0T1. At the same irrigation level, the soil internal friction angle decreased with increasing soil water content. Soil penetration resistance showed a decreasing trend with the application of biochar. The more irrigation there is, the larger the soil penetration resistance.","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"866-881"},"PeriodicalIF":1.6,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139387245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process uses a random data matching method to obtain operational management methods and system features using remote sensing data and water resource management optimization to evaluate different management methods. Regional modelling was performed, using the SWAP model under deterministic–stochastic conditions. Inputs such as sowing dates, irrigation procedures, soil characteristics, groundwater depth and water quality were treated as distributed data. To estimate these data, residual minimization was used between the field-scale evapotranspiration distributions modelled in the SWAP model and two Landsat 8 ETM+ images, as well as the Surface Energy Balance Algorithm for Land (SEBAL). The investigation of water management methods using distributed data as input was performed, and optimization of water management and data assimilation was achieved by applying the improved coyote algorithm. The case study was conducted in Mashhad during the dry season of 2018–2019. The results suggest that simultaneous consideration of crop and water management methods, rather than an independent evaluation, can lead to further improvement in regional wheat yield under water shortage conditions.","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"1010-1029"},"PeriodicalIF":1.6,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139141999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two lining materials were considered, cement concrete (CC) and CC with low-density polyethylene (LDPE) film. A cost analysis was performed to explore the feasibility of the proposed lining materials. Moreover, a parametric study was conducted by the Slide2 model to investigate the effect of canal geometry and liner properties on seepage losses. An artificial neural network (ANN) model was developed based on the Slide2 model scenarios to estimate the seepage losses from lined irrigation canals. The results showed that reach the discharge calculated from the FLOW-3D model increased by 92%–97% and 149%–156%, while the calculated seepage losses from the Slide2 model decreased by 81%–87% and approximately 97% under CC and CC with LDPE film liners, respectively. Cost analysis revealed that the overall cost of CC with LDPE film was higher by 14% than CC. Relying on the importance of saving irrigation water and conveying water to the last reaches, CC with LDPE film is recommended for lining irrigation canals. A parametric study showed that the seepage losses were reduced by more than 96% when the ratio between liner and soil hydraulic conductivities was less than 0.01. A thick liner could maximally decrease the seepage losses by 68%, regardless of the canal geometry. As the developed ANN model showed a close agreement with the Slide2 results with coefficient of determination (R2) and mean squared error values of 0.99 and 0.05, respectively, the ANN model is recommended as a robust and rapid tool for estimating seepage losses from lined irrigation canals.","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"910-927"},"PeriodicalIF":1.6,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141537061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
