C-165447
Quality of groundwater has not been a major constraint in the State of Kerala due to the frequent flushing of the phreatic aquifers by the prolific monsoon rains. However, there is considerable spatial variation in the concentrations of all the chemical constituents in the aquifers, caused by a host of factors including soil type, land use, geology, geomorphic set up and human activities. The hydrochemical characteristics of groundwater in different rock formations in Kerala have been interpreted from the analytical results of 505 groundwater samples collected from the phreatic aquifers. The hydrochemical characteristics, of the phreatic aquifers in River Alluvium, Coastal Alluvium, Laterites and Crystalline Rocks have been evaluated. Microbial contamination of freshwater is prevalent in the State due to shallow water conditions, high population density and associated sanitation issues. Fluoride and iron are two geogenic contaminants in the State, though mostly within negligible concentrations. The water quality and pollution by the inorganic constituents in groundwater are mainly discussed in this paper.
Water Resources Development and Conservation in Lakshadweep Islands, India
SKU:
C-165444
Groundwater is the major source of domestic water in most of the inhabited islands of the Union Territory of Lakshadweep. Groundwater occurs as thin freshwater lens floating over saline water. There is remarkable temporal variation in the thickness and areal extent of the freshwater lens, depending on contributory factors of which the mode of groundwater draft, diurnal tidal fluctuation, and the intensity & distribution of rainfall are of significance. In some of the very small islands, the freshwater lens is almost absent except during the rainy season. The islands are made of highly porous coral sand as topsoil, forming the aquifer material, resulting in almost entire rainfall on the ground percolating down, with negligible surface runoff even during intense rainfall. Thus there is not much scope for traditional artificial recharge into groundwater. Instead, direct harvesting of rainwater and conservation will reduce the stress on the fresh groundwater lens. The paper discusses the groundwater occurrence, resource availability in each of these Islands, its development prospects, and viable water conservation methods for freshwater sustainability.

Goa is drained by several rivers like Terekhol, Mandovi, Zuari, etc. and their tributaries, many of which show tidal influence and related saltwater intrusion. The surface water resources of the state have been assessed at about 8570 Mcum with 1465 Mcum utilizable resources (1125 Mcum surface water, 340 Mcum ground water). Presently, surface storages available are to the tune of 335.87 Mcum in the tanks, diversion structures such as bandharas, weirs, etc. The macro level surveys indicate ground water available is to the tune of 43.83 Mcum and utilization is to the tune of 33% which is considered as safe. Major and medium schemes like Salaulim, Tillari, Anjunem and minor irrigation schemes like Chapoli, Panchawadi, and Amthane irrigation projects cater to the agricultural needs of Goa State. The Sal-Amthane, Salauli-Kalay River Inter Linking Projects in Goa augmented the source to a tune of 156 lakh cubic meter. The paper discusses the water requirement and water resources management of Goa by 2051.

Water is essential for sustenance of life on earth. But the problem is unequal distribution of water in space and time. Ancients developed innovative ways to manage water resources to meet their essential needs like drinking water supplies and irrigation. Many parts of India, especially Rajasthan have been practicing water conservation and rainwater harvesting since historical times. Arwari water shed in Alwar district of Rajasthan has brought to focus traditional techniques of integrated water management with community participation. This paper attempts to briefly present the water management scenario in India since Vedic times.
Water Resources of Odisha ? Present and Future
SKU:
C-164715
Water is a major input in food grains production. The state of Odisha is bestowed with plenty of water resources. It receives 231 BCM of rainfall per annum, and the total annual flow through the river basins comes around 96 BCM. The present water requirement of the state is 55 BCM, which may increase upto 85 BCM in 2051 leaving a narrow gap between demand and availability. Unless the groundwater resource is developed to the optimum level, the state may face water scarcity situation in 2051. This needs appropriate land and water management adopting traditional techniques of water conservation, educating end users on scientific water use and increasing water use efficiency. The paper suggests several strategic actions in this regard.

C-164712
Odisha has 11 major river basins having a total annual flow of 84.815 BCM (75% dependable), out of which 19.136 BCM is from outside the state. Hirakud on the Mahanadi and Rengali on the Brahmani are the two largest multipurpose projects designed for irrigation coverage, hydropower generation and flood moderation. In addition to 11 major projects there are 50 medium projects completed or under construction. Because of increasing irrigation and other uses in Chhattisgarh, the flows in Odisha are diminishing. A careful planning may ensure irrigation coverage of 80% arable land in Odisha benefiting 40% SC/ST population. The paper discusses the water resources scenario in Odisha.
