{"title":"Water Resource Assessment and Optimization for the Hill Watershed of Southern China","authors":"","doi":"10.29011/2577-0640.1001198","DOIUrl":"https://doi.org/10.29011/2577-0640.1001198","url":null,"abstract":"This study introduces a water resource assessment and optimization system aimed at improving water supply and optimizing irrigation in the hill area of southern China. Focused on addressing drought vulnerability, hill flash flood prediction, and reservoir operation optimization by integrating Geographic Information System (GIS), Building Information Modeling (BIM), hydrology and hydraulic modeling (H&H modeling), and Supervisory Control and Data Acquisition (SCADA) technologies. The system’s structure involves a GIS model for reservoir watershed identification, a BIM model for essential reservoir data integration, and hydraulic modeling for flow simulation and storage optimization. Real-time data from strategically positioned SCADA sensors contribute to a continuous simulation database, enabling real-time monitoring of flow and depth, along with spatial and temporal rainfall forecasts. During drought events, the system transforms into a decision-support tool. The developed system was implemented in a southern Chinese village spanning 15 km ² of irrigated land with eight years of continuous precipitation records. The watershed has 22 on-stream reservoirs with varied storage volumes and irrigation demands. The project follows three phases: data collection and assessment, GIS and BIM model creation for daily operational analysis, and SCADA installation for engineering analysis. The third phase integrates a hydraulic model to predict, simulate, and optimize the irrigation system. Anticipating future progress, Genetic Algorithms and machine learning will be integrated for enhanced optimization and reduced management costs. Overall, this research embodies a comprehensive approach, merging advanced technologies and data-driven methodologies to provide practical solutions for agricultural resilience in the face of water scarcity.","PeriodicalId":92803,"journal":{"name":"Journal of earth and environmental sciences","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136378023","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}

Data were collected to study the morphological features of sheep of two Barind based upazillas; Paba and Godagari under Rajshahi district of Bangladesh through close observation, measuring and record keeping. Characteristics of body weight, wither height, rump height, body length, sternum height, Chest girth, bi-coastal diameter, ear length, rump width, head width, rump length, head length, heart girth, cannon bone circumference and muzzle diameter were collected from 508 (458 female and 50 male) sheep stratified into age categories of <1year, 1-1.5 year, 1.5-2 years, 2-2.5 years and >2.5 years by dentition. The average body weight of sheep was 18.03±1.91 kg irrespective of sexes and was significantly (p<.01) higher in male. The body weight of sheep was increased gradually with the advancement of age. The wither height (cm), rump height (cm), body length (cm), sternum height (cm), Chest girth (cm), bi-coastal diameter (cm), ear length (cm), rump width (cm), head width (cm), rump length (cm), head length (cm), heart girth (cm), cannon bone circumference (cm) and muzzle diameter (cm) were 52.75±2.56, 52.70±2.90, 55.61±3.04, 26.89±2.28, 61.65±3.38, 11.27±.88, 7.28±3.17, 13.57±1.03, 11.44±.85, 11.40±1.32, 19.02±1.47, 70.15±6.79, 8.56±.77, 20.04±1.52 respectively. The wither height, sternum height, body depth, bi-coastal diameter, head width, head length, cannon bone circumference and muzzle diameter were significantly differed (p<0.001) between male and female and value of all mentioned characters were higher in male. The results indicated that the rump height, body length, bicoastal diameter, head width, rump length, head length and muzzle diameter were non-significantly differed among different age categories but all of these were higher at aged sheep. Heart girth was differed significantly (p<.01) among ages and highest in full permanent teethed sheep. Cannon bone circumference differed significantly (p<0.05) among different ages and also highest at aged sheep. Though Heart girth did not differ significantly between sexes, it was higher in female probably for their pregnancy. Introduction Bangladesh is a sub-tropical country, favorable for sheep rearing, as they can be maintained under rural conditions because of their ability to adapt to harsh environment, poor management and feeding practices. There are about 3.537 million sheep in Bangladesh (DLS, 2019). Most of the sheep are indigenous, with few crossbreds [1] and are capable of bi-annual lambing and multiple births. Native sheep are extremely resistant to infectious diseases including PPR [2]. Under traditional feeding systems, the sheep are raised on harvested or fallow lands, roads, and canal sides [3] and also graze on aquatic weeds a","PeriodicalId":92803,"journal":{"name":"Journal of earth and environmental sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69471269","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}

Modern Environmental Management systems requires effective ways for the diagnosis of problems and identification of issues that affect coastal zones, in order to be able to handle diverse data and information about specific coastal zones. The application of Remote Sensing and Hydrography provide strong vertical as well as horizontal integration for Coastal Zone Management, specifically issues related to Ecosystem and Environmental Management, as well as economical and developmental issues. Bathymetric Remote Sensing provides capabilities of seamlessly addressing issues related to land cover, land use for coastal or near shore zones. Integrating this data with data from Singlebeam and Multibeam echo sounder can provide detailed water depth information that are useable as bases for building 3D models for underwater environments. 3D coastal models are of great benefit in coastal development activities, such as infrastructure construction, as well as facilities establishments. This report will provide a general overview of the key benefits from Remote Sensing and Hydrography integration for coastal zone management.","PeriodicalId":92803,"journal":{"name":"Journal of earth and environmental sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69470987","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}

Several urban ponds in the Northern Kentucky, USA area were monitored for algal community (algae and cyanobacteria) from October 2012 to September 2013. Many of the harmful algal blooms observed during this study were composed primarily of the cyanobacteria genus, <i>Microcystis.</i> No correlations were observed between basic water quality parameters (dissolved oxygen, pH, conductivity, temperature, nitrate and soluble reactive phosphate) and the presence of cyanobacteria and/or microcystin cyanobacterial toxin levels. Furthermore, levels of microcystin toxins did not always coincide with high <i>Microcystis</i> cell counts. Harmful algal blooms in small urban ponds are common which pose risk to human and ecological health due to proximity of dense human population including pets and wild animals. Because harmful algal blooms were detected throughout the year in this study, adaptation of universal guidelines for the design, construction and maintenance of urban ponds may be necessary to protect watershed aquatic ecosystems, and lower health risks from exposure to such harmful blooms.</p>","PeriodicalId":92803,"journal":{"name":"Journal of earth and environmental sciences","volume":"25 ","pages":"704-726"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6865815/pdf/nihms-983331.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49686117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
