Rainwater harvesting

The objectives of the current study are to develop a methodology to estimate the optimal size of the rainwater tank at a particular location considering the local rainfall, roof area, demand for water and the reliability of supply (supply security) required; to quantify the rainwater volume that could be harvested at site using domestic rainwater tanks to minimise pressure on the potable water supply secured from traditional catchment sources until the desalination plant is commissioned in 2013; to analyse the efficacy of rainwater tanks to reduce the stormwater runoff and improve the quali...

A number of technological and socio-economic constraints are cited for this poor adoption and up-scaling. With climate change posing a major challenge for rainfed agriculture and the constraints in further expansion of irrigated area in the country, rainwater harvesting and efficient water use are inevitable options to sustain rainfed agriculture in future.

One of the easiest and efficient way of water conservation to solve drinking water scarcity is rooftop water harvesting. However, the technology has some limitations with regard to its purification system. The commonly used sand and gravel filter is very prone to clogging and its cleaning is not an easy job. At the same time, the alternative upward flow mesh filter needs further improvement in cleaning efficiency and some hassle free drain cum back washing mechanism. In upward flow mesh filter system, which creates anaerobic condition will give foul smell.

An evaluation was conducted to develop a stochastic time series model, capable of prediction of rainfall and runoff in Karso watershed. The Karso Watershed selected for hydrological studies is one of the sub watershed of the Damoder dam catchment of upper Damodar Valley, comprising a cover the area of 27.41 km2 . The hydrologic sequences data of watershed collected from Soil Conservation Deptt., Damodar Valley Corporation, Hazaribagh, Jharkhand State were analysed. The watershed be capable of be divided into three main landscapes.

The knowledge of crop water requirement and Irrigation scheduling is an important practical consideration for designing and managing an irrigation system. A field study was conducted to find out the irrigation scheduling of Mustard crop by Climatological method and its comparison with CROPWAT model from rainwater harvested through plastic lined pond during the year 2018-19 at PFDCPET farm of the BAU Ranchi Jharkhand.

Groundwater is a dynamic and replenishable natural resource, but in hard rock terrains, availability of groundwater is of limited extent and is depleting in many areas due to its large scale withdrawal for various sectors. Groundwater recharge such as rainwater harvesting is essential in order to improve ground water level and quality. The main objective of the study is to identify suitable sites for groundwater recharge in the study area through Geospatial technology. To attain this Remote Sensing Technology is the good tool in mapping such geological features related to groundwater recharge.

Rural development as an integrated concept of growth and poverty elimination has been of paramount concern in all the consequent Government Schemes. The major challenge for our Governments is to offer solution that enables rain fed farming towards sustainable agriculture. “Krishi Bhagya” is the Government„s flagship programme is a step towards to achive sustainability among rainfed farmers of the state. Government is supporting farmers to make a farm pond with polythene lining (to prevent percolation), install pump and sprinkler irrigation system (for efficient water utilization).

The present investigation was carried out in Dharwad Taluk (Karnataka) during 2007- 2008, to evaluate the influence of weather parameter on ground water level and the impact of Rain Water Harvesting on farming economy. Monthly data on weather parameters and ground water level recorded by District Statistical Office, Main Research Station Dharwad and Department of Mines and Geology Dharwad respectively for 28 years were collected. Primary data were collected from the randomly selected 60 sample farmers of both with and without Rain Water Harvesting Systems.

Water scarcity has many negative impacts on the environment, including lakes, rivers, wetlands, and other fresh water resources. Furthermore, water shortage makes flow management in the rehabilitation of village streams problematic. Owing to poor water resource management system and climate change India faces a persistent water shortage. Indian agriculture accounts for 90% water use due to fast track ground water depletion and poor irrigation systems. Water is a critical input into agriculture in nearly all its aspects having a determining effect on the eventual yield.
