Authors: Reddy, M. T. Maruthesha; Prabhakar, B. C.; Brungesh, K. V.; Akshatha, M. R. Abstract: Hosakote is a Taluk in Bangalore Rural District. It’s headquartered at Hosakote town, 25 km away from Bangalore City. Currently, Hosakote depends on ground water (bore wells) as the main source of water supply. Due to depletion of rainfall year by year, overexploitation and less recharges, the yield from the borewells are diminishing considerably. In summer season, the water table goes much below thus creating scarcity of water. Hence, the ground water source is not dependable and there is an inevitable need to develop a project for alternate source of water supply. And as such this paper presents the water problems in the Taluk, the reasons for the problems and remedies to correct the problems. The scope of this paper includes: i. Profiling of Hosakote Taluk and understanding their water requirements and demands. ii. Identifying environmental and social impacts of the suggested remedies and to suggest mitigation measures to overcome these impacts. A preliminary feasibility report entitled, Integrated Water Supply project. 2016-01-01T00:00:00Z http://13.232.72.61:8080/jspui/handle/123456789/453 Title: Occurrence of Droughts in Hoskote Town, Bangalore Rural District, Karnataka, India Authors: Maruthesha Reddy, M.T.; Sirisha Reddy, Y. C. Abstract: Hoskote Taluk is one of the eight Taluks of Bangalore Rural District in Karnataka with a current approximate population of 3, 03, 428; the total water demand comes out at around 49.5 MLD @ 135 LPCD, (WHO Standard). However with increasing population and depleting water resources, the people there do not get water even @ of 80 MLD (GOI standard for urban areas). With no surface water and declining water table below the ground, the greatest challenge the Taluk is currently facing and will face in the future is to meet the water demand of the population. There are five rain gauge stations in the area and are located in Hoskote, Hindiganala, Sulibele, Jadigenahally and Anugdanahally. In view of the scantiness and the variability in duration of these rainfall data, only data of Hoskote station, which is incidentally the taluk head quarter station, has been considered for the present study. For suggesting any remedies to solve water shortage and to help improve the current water resources, rainfall data from different sources for past 43 years is collected and analysed. And as such this report presents the rainfall data collected from Hoskote rain gauge station. Long term mean annual rainfall and its seasonal variability, trends of rainfall and probability studies with respect to drought, etc. Graphs are then prepared from these collected data and used for analyzing the data and to project the assumed future data. Statistical analysis of data yields rainfall pattern of the study area, rainfall pattern can be used to predict future rainfall quantity in Hoskote Town. 2015-11-01T00:00:00Z http://13.232.72.61:8080/jspui/handle/123456789/452 Title: Change Recognition in Land-Cover Dynamics for Bangalore City due to Rampant Urbanization, using Quantum G.I.S. Authors: Ramya, R.; Gopinath, Rajesh; Soren, Jayant Kumar; Chourasia, Rohit; Izhar, Md.; Shetty, Anush M. Abstract: The present research engages Quantum G.I.S. as a tool in order to reflect on land-cover pattern changes of Bangalore region for the past 15 years, with the aid of satellite imageries that were downloaded and pre-processed as a part of the exercise. Training sets were marked that included different land-use patterns in the imagery and then the images were subsequently classified leading to the determination of area. The research unveiled that water-cover was worst affected with 69% loss, followed by green-cover at 5.2% loss. While there was meagre shift in loss of barren land, all these had subsequently contributed to a multi-fold rise in built-up spaces by 125% gain. The study inferred that the rampant urbanisation of Bangalore in the name of development has to be brought to a standstill and alternate plans needs to be devised with minimal environmental disturbance in terms of land-use pattern, and this can be achieved only if a tool such as Quantum G.I.S. is incepted in the planning stages itself. 2015-01-01T00:00:00Z http://13.232.72.61:8080/jspui/handle/123456789/451 Title: Status of Ground water Quality, Hoskote Taluk, Bangalore Rural District, Karnataka, India. Authors: Maruthesha Reddy, M.T.; Prabhakar, B. C.; Akshatha, M. R. Abstract: The quality of groundwater in nature is determined by quantum and nature of recharge, chemical composition of the soil cover and its thickness, mineralogical make up of the aquifer, residence time of the water which is governed by the transmissivity of the formation. The two important characteristics of the crystalline terrain, which covers practically the entire Taluk, are the heterogeneity and preferred flow paths. They have a dominant role to play in determining the quality of the ground water with the result; large variations are noticed in short distances. Thus it is not uncommon to get varied quality of water even in a small village. This fact is to be borne in mind while locating sources of water supply for various uses. Quality data in respect of 14 parameters of all the drinking water sources in the villages is available with PRED. Summaries of bore well sources, Gramapanchayat wise which is presented in Table 1.1. The same has been collected and analysed. The range of value in respect of 14 parameters are given in table 1.2 Table 1.3 summarizes the number of wells with a quality problem in the Taluk. As seen the most commonly observed problems relate to the total dissolved solids, Total hardness, Turbidity, Calcium, Iron and Fluoride. The strategy to be adopted in providing solutions to these villages is discussed. As for the irrigation requirement, the two important quality parameters are Sodium adsorption ratio and total dissolved solids are indicated by the Specific conductance of the water These determine the Salinity and Sodium hazard from the irrigation water. These determined from the results available in the records of DMG. Considering the fact that large areas of the Taluk are covered by red soils and mixed soil, it is very important to study the soil water inter relationship before undertaking irrigation practice. It can be safely concluded that in red soil areas, the quality of ground water is safe for irrigation and has low to medium salinity-low sodium hazard. 2016-03-01T00:00:00Z
