Water Harvesting Structures

It is a well-known fact that it is not all possible to avoid droughts, but droughts can be managed to minimise the hardships of the local population. For this purpose, understanding of the supply-demand scenario is of utmost importance to understand the overall hydrology and planning needs of any watershed. It is in this direction, the comprehensive water balance analysis has been performed for the Sajnam watershed in Lalitpur district of Bundelkhand which is susceptible to regular and continuous droughts. The detailed water balance has been carried out after identification of important components and their quantification using the advance tools of Remote Sensing and GIS alongwith standard estimation techniques of individual components. It was observed that the runoff at the outlet of Sajnam basin is influenced by the water storage in the irrigation project located on the main river. The higher surface runoff of 668.53 MCM, 406.17 MCM, 343.46 MCM and 214.00 MCM is generated only during 2013-14, 2008-09, 2012-13 and 2010-11 respectively. During the remaining years, the runoff varied between 89.35 MCM and 209.81 MCM. Efforts can be initiated towards exploring the possibility of more water harvesting structures onthe lower order tributaries as well as artificial recharge measures depending on the hydro-geology of the watershed..

Abstract. Water management is a fundamental issue in post-conflict planning in Syria. Based on historical water balance assessment, this study identifies the drivers of the profound changes that took place in the Lebanese and Syrian parts of the Orontes River basin since the 1930s. Both drastic effects of the conflict on the hydro-system and the strong uncontrolled anthropization of the river basin prior to the crisis have to be considered in the design of recovery interventions.

Abstract The Water Balance Assessment is a methodological approach developed and applied by Eni for the identification of improvements in water management at site level. The approach is based on three steps. The following report describes each step and the application of the approach to a real case study in Tunisia. Water is a vital resource for our planet and for humankind. Biodiversity and ecosystems’ preservation, human health, and food security as well as energy production, industrial development and economic growth are all dependent on water. The consequences of climate change and the actual projections of increasing water demand will affect water availability and quality in the coming years. About the Oil & Gas sector, this industry consumes and produces significant volumes of water. For this reason, energy companies must consider sustainable options for the use of this resource, especially in water stress areas. This can be achieved through:A deep knowledge of the site water streams and of the context where the site is located.Identification of improvements and initiatives that could reduce the water risk of the site. About water safeguarding, Eni is committed to pursue the following practices:Water Conservation: Upstream Oil & Gas operations need significant quantities of water; a key element for its conservation includes the reduction of withdrawals and the efficiency in water use.Water Reuse and Valorization: Upstream Oil & Gas operations must manage large volumes of wastewater, mainly Produced Water. Design solutions shall introduce and maximize the recycle of water with the adoption of suitable treatments, to make discharges compatible with the reuse in the same production cycle or by third parties (e.g., other plants, local communities), and pursue the opportunity to reuse industrial water, instead of discharging it as wastewater. For their deployment, Eni has defined and applied a methodological approach to support the definition of improvement and optimization initiatives of water management at the site level. The approach represents an application of a "convergence approach" which, starting from an overall view of the site, identifies opportunities, further and more detailed areas of analysis, and design projects that can improve water use, management, and reuse. The methodological approach is based on the following steps:A country-based framework study on water resources, and water-related risks analysis at country and local level.A Water Balance Assessment, gathering water qualitative and quantitative information and site framework details.Definition of site initiatives for wastewater reuse and valorization, and for the optimization of water withdrawals, based on the above steps and considering local legislation. Through this approach, operational water risks exposure is analyzed in detail, allowing to address a wide range of opportunities for the improvement of water management, also through the development of new synergies with local communities.

<p>Ljubljana field aquifer is an important source of drinking water for the Ljubljana city and surrounding areas. Knowledge of the water balance and of the water flow dynamics through the unsaturated zone and recharge of Ljubljana field aquifer is crucial. The water balance assessment of the upper unsaturated zone provides an insight into groundwater recharge and renewal. With the help of build-in monolith weighing lysimeter in Kleče in Ljubljana we have assessed the water balance for hydrological year from March 2014 to February 2015. Water balance parameters, precipitation and evapotranspiration were determined from the changes in the mass of lysimeter and outflow tank. Precipitation events were evaluated based on their duration, intensity and the amount of precipitation. Evapotranspiration and the duration of precipitation were estimated based on the changes of the lysimeter mass. Results show that the chosen period was extremely wet. In the selected hydrological year, precipitation contributed to positive water balance of the upper unsaturated zone, as well as to the recharge of the aquifer.<strong></strong></p>
