A pond ecosystem is a composition of plants, animals, microorganisms, and the physical environment in which they live and has different elements that work to maintain ecological balance. Tripura is known for its abundant pond ecosystem, which the community manages for its livelihood purpose. In this study, three different-sized ponds were selected from the Khowai district of Tripura. The water physic-chemical properties and plankton diversity of three different sized ponds were assessed as per the standard procedure. It was observed that the biochemical oxygen demand (BOD) is high in the large pond, whereas the level of dissolved oxygen (DO) was found to be less in this category of the pond. However,the DO level was higher in small ponds, and the medium pond is also within the acceptable limit. The pH results also revealed that the water has become chiefly alkaline in a large pond and moderately acidic in a medium pond. During the study, 43 species of phytoplanktons from 4 families were identified. Maximum species (31) were recorded from small ponds followed by medium (17 species) and a large pond (15 species). The most dominant phytoplankton families were Chlorophyceae (37%) and Eugleanophyceae (26%) in pond ecosystems. Though the small-sized ponds are more diverse and suitable for aquatic life, however, the large-sized ponds are economically viable for this region. So, the people and Government should take some initiatives for conserving those pond ecosystems for the betterment of society.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"500 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":"132162061","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 Irrigation management faces issues of less capacitated water distribution systems than its apex requirement, has irregular supply rate, low inundation efficiency, and consistency. It is important to measure the delivered water supply with required water delivery in proportion to its demand. The auto water elevated gauges which are fixed at the back and front segments of each inundation canal at the left bank channel of the Godavari river assess the discharge of supplied water during the irrigation period. In the current research, the computation would be conducted for the water delivery performance indicators such as competency, productivity, prominence, and rectitude, which are fundamental for the assessment of the irrigation and drainage system management. According to the water supply performance indicator, the inundation ability is calculated with an automatic water gauge. It is measured from the structural and transient channeling of water discharge to examine the inefficiency of water supply management. The cumulative results of the performance indicator demonstrate the enhanced methods to develop water management policies that will facilitate the irrigation planners with improved temporal consistency and reasonable water distribution.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"8 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":"125149701","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 paper presents a study of the dynamics of changes in channel planform and measurement of the erosion and accretion of the Kankai river in Bihar, India from 2000 to 2018. Spatial data were processed in GIS to determine the changes in sinuosity, centreline migration rates, and extent of erosion, and deposition of sediment. The maximum river shift was obtained as 800 to 1600 m and the minimum river shift varied from 6 to 70 m. With a sinuosity ratio for the whole reach of the river of 1.45, the Kankai river is considered a sinuous river and needs river training works at the erosion sites.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"20 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":"124965241","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 groundwater’s geochemical control and hydrogeochemistry were evaluated using the Piper plots and water quality index (WQI). The hydrochemical analysis reveals that the groundwater is predominantly of CaNaHCO3 type, Water quality index (WQI) indicates that 33% and 2% of groundwater samples fall in poor and very poor categories for drinking purposes. This study reveals that groundwater quality is unfit for drinking purposes at a few places. The effective leaching, dissolution process and rock-water interaction process are the main sources for degrading the groundwater quality.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"42 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":"130171654","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, the system is active and it must be well examined before any infrastructure is planned, to avoid harm from natural processes like degradation, sedimentation, and sometimes sea-generated natural disasters. Numerical modelling of the coast to forecast the area’s natural parameters is an important technique for assessing these systems. Coastal regions are of critical importance to most of the world’s citizens with a significant bearing on economic activities. In the present study, a well-calibrated mathematical model of Vengurla, Maharashtra, has been developed using MIKE 21 flexible mesh software, with the latest prototype data and also carried out 2-D hydrodynamic studies for the proposed 500m breakwater and approach channel. The simulated model will be tangled with the sediment transport model to ascertain the likely pattern of siltation in the area. After studying the Hydrodynamic model, it was observed that in existing conditions, currents varied in the range of 0-0.02 m/sec inside the Vengurla creek and 0-0.15 m/sec in the seawater and currents under the proposed condition varied in the range of 0-0.029 m/sec inside the Vengurla creek and 0-0.22 m/sec in the seawater. No severe circulation or eddies were observed near the beach area in the existing condition as well as in the proposed condition, hence no siltation has occurred in that area. From the sediment model, it was observed that there is not much siltation/erosion after the construction of the proposed breakwater and deepening of the approach channel.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"194 7 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":"127562909","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}

Rapid growth of population is a major cause of harassing the natural resources and groundwater is one of them. The methodology for groundwater resources assessment in India is mainly based on Ground Water Resources Estimation Committee,1997 and it involves assessment of annual groundwater resources recharge, annual groundwater draft (utilization) and the percentage of utilization with respect to recharge (stage of development). The assessment units (blocks/watersheds) are categorized based on stage of groundwater development (utilization) and the long term water level trend. This study estimates the recharge and draft of Groundwater in Arwal District due to uses for irrigation, domestic and industrial uses, etc. The characteristic of annual rainfall, monsoon rainfall and non-monsoon rainfall were analyzed. The average annual rainfall of Arwal district is 743.05 mm, monsoon rainfall as 654.18 mm and non-monsoon rainfall was recorded as 66.87 mm. Groundwater recharge was estimated at 49766.15 ha-m and draft was determined as 52973.15 ha-m. Population study of district was forecasted using Geographical Increased method. Based on this study results, the total annual demand of water for Domestic purposes was estimated at 41.09 MCM. Draft of groundwater was observed more than recharge of groundwater. This needs proper planning and management of existing groundwater resources.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"27 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":"133225410","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}

Rejuvenation of the water structure leads to the creation of storage or increase in the storage capacity of the existing structure, eventually aiding to groundwater recharge.\u0000“Sujalam Suphalam” is a District level time-bound program that focuses on the improvement of village water resources by undertaking the restoration of existing water bodies, and watershed treatments for the augmentation of groundwater. It is an effort to make a parched village 'water abundant' by creating water infrastructure that\u0000instils the notion of ownership amongst the stakeholders which is an important element in arriving at a sustainable solution for drought frequented regions in a short period of time. Sujalam Suphalam (SS) takes a multi-stakeholder approach to arrive at village water security. The multi-stakeholder design of the programme involves the Government (State and District Administration) – Bharatiya Jain Sanghatana (BJS) -Community/Farmers Group – like-minded civil society organisations and advocacy groups (public representatives and newspaper & electronic media) as the stakeholders. Where Government authority provides necessary sanctions and takes full ownership of the programme, BJS provide their services of heavy machinery and support the Government in programme execution, implementation, community mobilisation, data\u0000management and monitoring. This program promises rejuvenating water structures that store run-off generated during monsoons, which recharges groundwater, these earthen works also provide an essential resource to the farmers which is silt to enhance individual farmer's productivity. SS has helped in increasing the agricultural\u0000income by bringing the larger area under irrigation and enhanced the income from agro-allied diversified activities. By desilting percolation tanks, water harvesting tanks and village nalas (rivulets) BJS has not only enhanced the storage capacity of these structures but also increased the period of water availability in the parched\u0000villages. It increased the number of days of drinking and domestic water availability accessible to all habitations within a village. The approach promises to reduce the gap between demand and supply of both, water and silt, in a short period. It also garners active participation from the farmers that leads to effective management of community water resources by enhancing the capacity of Panchayati Raj Institutions and individual farmers. Since the implementation of IWRM projects back in the 1970s, many water storage structures were created in drought-prone villages. But often it was found that very few programs were concentrated on rejuvenation or repair of these water bodies. Often the Gram Panchayat was given charge of these water bodies who lacked the necessary guidance and resources to rejuvenate or repair.
