Irrigation and Hydropower of Goa
Goa is situated within the Konkan region and is that the smallest state in India. Substitutable with tourism in India, Goa remains one among the favourite traveller destinations for millions across the world. Bordered by the Arabian Sea on its west, Goa is blessed in terms of topographic beauty. Goa is split into 2 districts North Goa and South Goa. This small state is set on the western coastal region of the Indian ground. Geographically it bears a hanging alikeness to its neighbour states of Maharashtra and Karnataka. It lies between 15°48’00” north to 14°53’54” north latitudes and 74° 20’13” east to 73° 40’33” east longitudes. The one distinctive feature regarding the geography of Goa is that it’s a seamless concoction of mountainous, highland regions and coastal plains.
Panaji virtually suggests that land that never floods. It is the capital and most well-liked town in Goa. Goa, a petite state placed on the West Coast of the peninsular India, is presented with 9 major rivers of that the Mandovi and therefore the Zuari Rivers are the key and important rivers from irrigation and hydropower purpose of read. Spatial and temporal variation of precipitation in these basins has nice influence on water resources of the state. visible of this, on the idea of accessible monthly precipitation knowledge from 1901-2012 and daily precipitation knowledge for the amount of 2001-2012 for the stations placed in north and south districts of Goa were analysed to review the mean monthly, seasonal and annual precipitation intensity, trends and its spatial distribution; severe rainstorms and their rain depths for various durations. The analysis are going to be vital in water designing comes particularly, for irrigation, hydropower and control, etc. for the Goa state.
Goa being a small state depends on its neighbouring states for milk, poultry and vegetables. Rice which is cultivated within the rains from June to Sept is that the major crop followed by cereals like pulses and tiny millets. The betel nut, coconut, cashew are the opposite major plantation crops here and therefore the garden crops embrace pineapple, mango, bananas and jackfruits. Conjointly from the forest varied kinds of barks and bamboo canes are harvested.
Goa holds quite forty estuarial, eight marine and just about ninety reverie islands. There are 9 major rivers in Goa flowing from East (Western Ghat) to West (Arabian Sea) except Sal River. Terekhol, Baga, Zuari, Sal, Chapora Saleri, Talpona, Mandovi Galgibag are the most 9 rivers of Goa. Among these rivers, Mandovi and Zuari drain 2553 Sq. km, regarding 70th of the full geographic area of Goa. Out of the 9 rivers, six originate and flow completely at intervals the state boundaries and don’t have any interstate implications. However, watercourse Terekhol and Chapora originate in geographical area state whereas Mandovi originates in Karnataka. These rivers kind an integral a part of Goa life thanks to their movableness, irrigation facilities, agriculture and coastal resources, transportation of mining ores, etc. Most of the rivers are passable and of vast economic importance as ores ar transported through these rivers to Mormugao port for export. There are 2 major lakes viz. Mayem and Carambolim. For any hydraulic project connected with irrigation, hydro-power generation, control and drain, it’s necessary to get the spatial and time distribution of precipitation related to the storm and to gauge the common depth of precipitation yielded by it over a specified space throughout the storm amount. A storm is outlined as a spatial distribution of serious rainfall, yielding average depth of precipitation that equals or exceed a precise threshold price over a neighbourhood in association with some meteorological phenomena viz. low pressure areas, depression or cyclonic storms etc.
The Tillari irrigation project may be a joint venue of government of Goa and Governm
ent of Maharashtra. It envisages the development of a stuff dam across watercourse Tillari, a west flowing river originating from Sahyadri Mountains in Chandgad taluka of Kolhapur district of Maharashtra state, crosses Maharashtra state close to village Maneri to enter Goa state wherever it is popularly referred to as Chapora.
Irrigation cum power outlet tunnel has been planned on the left facet of the saddle waste weir for cathartic the water into neighbourhood canal through the ability house with 10 MW put in capacity.
Canal system: Left Bank main canal takes off from ICPO tunnel and runs 18.379 kms in Maharashtra state and thirty seven.40 kms in Goa state. It carries a discharge of thirty two.56 cumecs at head. It commands a region of 1698 ha in Maharashtra and 19971 ha in Goa. Neighbourhood main canal flies from the Terwanmedhe devour weir and runs 24.692 kms in Maharashtra and 23.75 kms within the Goa state. The discharge capability at the pinnacle is 2.89 cumecs and its additional increased t 14.50 cumecs through the link canal at Ch 14.775 kms in Maharashtra. It commands a region of 4978 ha in Maharashtra and 5007 ha in Goa. Link canal flies from LMBC at 13 kms and runs 3.53 kms to affix with RBMC close to village Parma, when organic process Perma watercourse through the conduit. It carries a discharge of twelve cumecs for augmenting the discharge of RMBC. Banda branch flies from RBMC at Ch 6.02 kms (Goa portion) and runs for a length of 57 kms within the Maharashtra state with a designed capability of 6.5 cumecs to cater the needs of Maharashtra. Sanquelim branch canal takes off from LMBC at Ch 1.700 kms (Goa portion) and runs for a length of 14.00 kms with a style capability of 4.46cumecs.
Benefits of the project and also the value estimates are delineated within the paper. The project can go an extended means in irrigating a significant chunk of land in north Goa, and can additionally satisfy the growing wants of drinking and industries within the state for an extended time to come. Considering the water resources scenario of Goa, the project can play a significant role within the development of the state.
