Shifting cultivation provided a way of life for most of the ethnic groups of north eastern states. Policy approach to deal with shifting cultivation in Arunachal Pradesh aims to replacing it with permanent forms ofland use by cultivation of oil palm as per availability and suitability of land. In Jhum land area oil palm plantation may be promising in the state. However, as per the requirement of climatic factors and availability of irrigation water, the oil palm cultivation could be practiced in areas where a compact area between 450-500 hectares of land and sufficient rainfall and SUlllly days are available. Since, the minimum land requirement for oil palm plantation, advocated by NRCOp, is 500 ha, a total number of nearly 60,000 nos. plant may be grown in such a composite oil palm garden. In view of non availability of a considerable land area of 500 hectares under single holding and cost involvement, community participation should be encouraged. Since irrigation water requirement of each plant is 200 litres per day, total quantity of 12 million litres or 0.012 MCM of water per day would be required for sustainable growth of such oil palm plantation. Various practices of watershed development can also be applied in the sloping terrain. In the foothill areas of Arunachal Pradesh, with optimum minimum temperature of 6-10°C, shallow aquifers may be tapped with shallow tube wells or dug wells/collector wells with infiltration galleries. Surface water/rain water resources could be developed in and around Jhum cultivation areas through construction of check dams in series with sub surface dams and through construction of ponds.Keywords

Selecting the appropriate small hydropower project site in which to invest is a critical task involving different factors and policies. Small hydropower projects are emerging as a solution for sustainable, green, environment friendly and long term, cost effective source of renewable energy in India for the future. Hence such decision-making can be viewed as a multiple criteria analysis problem with correlating criteria and alternatives. This task should take into consideration several conflicting aspects because of the increasing complexity of the social, technological, environmental, and economic factors. Traditional single criteria decision-making approaches cannot handle the complexity of such systems. Multi criteria methods (MCDA) provide a better and flexible tool. This paper aims to evaluate applicability of multi criteria decision aid to decision makers during the small hydropower project planning and development. To the best of the author‟s knowledge this novel approach for application of MCDA to small hydropower project planning and development scenario is absent in renewable energy literatures due to its assessment complexity.Keywords

Since the British period the Damodar River has been the main source of water supply in Raniganj, Asansol and Durgapur area of West Bengal State in India. Afterwards since nineties, the drinking water demand was increasing rapidly with the population rise. There has been a considerable scarcity in water supply especially in summer months. Recently, to augment the water supply situation, considering future demand and population rise, a hydro-geological study has been carried out during dry period at different locations on the river bed. The observation were undertaken in and around the existing pumping area on Damodar river located in the southern part of Raniganj. This research is aimed at assessing the yield test at exploratory bored wells to find out the minimum quantity of water available to design radial collector wells at three different locations with respect to their drawdown, transmissibility and storativity. Secondly, a field method for the mechanical analysis of bore well log material of the study area was attained to determine the material size and the required artificial gravel packing. On the basis of the field study and investigations, data collection, collasion and analysis, this paper has been prepared highlighting the characteristics of the aquifer, the location of the intake wells and yield of the bed.Keywords

Management measure for Irrigation water by tidal back-water influx is an important issue for the sustainable living of rural communities in the areas where the rainfall is insufficient for rabi crop cultivation. Tidal back-water influx is one of the sources of irrigation water in the lower gangetic planes of West Bengal, India. Based on that concept, a plan is provided for the Magrahat basin of South 24 Parganas district in West Bengal for the augmentation of irrigation facilities through excess amount of tidal back-water entry during the post-monsoon period when the salinity of water is considerably low. In the present study, twenty major canals or khals of Magarahat basin are considered. Volume of available tidal water for irrigation of rabi crops was determined from the gauge data of tidal rivers. Here an attempt has been made to delineate not only the enhancement of the economic return of the people of the Magrahat basin but also to create provision for multi-cropping (rabi crops) pattern of agriculture/horticulture facilities during the dry season for sustaining of their livelihood. Also the tidal backwater surface profiles have been suggested for all the major canals of Magrahat basin using standard step method of gradually varied flow.Keywords

The three-dimensional flow field at a flat plate (side facing the approaching flow) under clear water equilibrium scour regime was experimentally measured using an acoustic Doppler Velocimeter (ADV) in a laboratory tilting flume. Reynolds stresses at different azimuthal planes are computed. The bed shear stresses are determined from the Reynolds stresses and velocity gradients at different azimuthal planes (0°, i.e., at the upstream axis of symmetry, 45° and 90°). The critical bed shear stresses on the sloping beds are also computed with the help of Shields' diagram. The findings of the present study were also compared with the results obtained by previous researchers.Keywords

Mechanism of erosion along a riverbank is full of complexity in nature. Among many forces on the sediment particles along a riverbank, cohesive and viscous forces are predominant. A family of similar particles surrounds every particle and they are bound together under the action of cohesive and viscous forces. In this paper, sediment particles are arranged according to the truncated pyramid model and a general equation for the escape velocity of a particle has been suggested. It is observed that this escape velocity is very much dependent on the inter-particle separation distance for a given liquid bridge volume between a pair of adjacent particles. Determination of the escape velocity is an approach to quantification of volumetric erosion rate. In this paper, a comparison has been made between the values of the escape velocity obtained from a previous study considering only cohesive force and the values of the escape velocity obtained considering both cohesive and viscous forces for a particular liquid bridge volume. All the other parameters remain the same for both the cases. It has been shown that the values of the escape velocity obtained in the present study considering both cohesive and viscous forces increase a considerable amount than the values obtained in the previous study considering cohesive force only for the same input parameters.Keywords

In this paper it has been shown that the cohesive force binds the particles on a riverbank. The escape velocity of the particles is a function of the inter-particle distance, the mean radius of the particles and the volume of water entrapped between them. The escape velocity is the velocity required by a particle to get separated from the riverbank. It helps in determination of other relevant parameters like volumetric rate of bank erosion, entrainment rate and so on. Unlike the previous research here light has been thrown on the cohesive force between the adjacent particles in a deterministic manner. The influence of a gradual increase in the volume of water bridge on the escape velocity of a particle has also been studied.
An analysis of the data has been made to find the level of significance of the input parameters. This includes a regression analysis for calculation of the residual values between the predicted and the calculated escape velocities. Corresponding graphs have also been plotted to present these variations pictorially.

A particle on a riverbank is subjected to a number of forces. Among them, cohesive and viscous forces are predominant, hi this present work, an analytical model called the Truncated Pyramid Model has been used to quantify the effect of the viscous force on the particles on a riverbank and the dynamic influence of water entrapped between the particles. For this, the existing model has been suitably modified to incorporate the viscous effect. The whole mechanism involves a good number of variables namely inter-particle distance, separation speed, liquid bridge volume, radius of the sphere particle and radius of the wetted area. In this work, cohesive and viscous force components have been resolved along horizontal and vertical directions and two separate differential equations have been established for horizontal and vertical components of separation speed that is varying with time. Variation of separation speed with separation distance for a particular liquid bridge volume at different times has been evaluated thereafter.

The phenomenon of erosion of a riverbank is extremely complicated and various forces act on bank sediments. Cohesive force between these grains and the force due to seepage of water play an important role among those forces. The present work uses the ‘‘Truncated Pyramid Model (TPM)’’ for the arrangement of grains and proposes generalized equations for calculating escape velocity under cohesion and seepage. The effect of seepage force along with the cohesive force has been studied for different degrees of exposure (fully exposed, half exposed and fully submerged) and compared with the previous study where only the force of cohesion was taken into account. The change in escape velocity due to seepage force for different degrees of exposure has been determined in this paper for three different grain sizes (300 µm, 400 µm and 500 µm of radius) along with different inter-particle distances.Keywords

A laboratory experiment was conducted by placing a 50 mm diameter horizontal cylinder across the flow and a 50 mm wide vertical plate at 55 mm downstream of it in a flume to observe and compare the surrounding flow fields past these structures. The cylinder vertical position was altered from 0.3 to 0.4 times of flow depth of water. Around these structures, the obtained flow fields, vortex formation, and turbulent characteristics are analyzed, compared and discussed.Keywords
