Abstract:

In many areas of India, increasing groundwater use has led to depleted aquifers. Rainwater harvesting (RWH), the small scale collection and storage of runoff to augment groundwater stores, is seen as a solution to the deepening groundwater crisis in India. However while the social and economic gains of RWH have been highlighted, there has not yet been a thorough attempt to evaluate the impacts of RWH on larger catchment hydrological balances.

Abstract:

Rainwater harvesting (RWH) in the UK has seen a low level of uptake relative to similar settings such as Australia and Germany. The relatively low cost of municipal water in the UK limits the financial savings associated with RWH systems, especially in a domestic setting. Although financial benefits can be relatively low (in terms of reduced water bills), academic and practitioner studies have demonstrated the potential for RWH to significantly reduce potable water demands at typical UK houses. Hence, increased uptake of RWH has potential to contribute to mitigating droughts in water scarce re

The approach to rural water supply and management in developing countries is a concern for world organisations and national governments. There is an increasing need for a shift from a centralised infrastructure, which often are not functional to decentralised systems such as rainwater harvesting. With increasing water demand and flood risks, the value of RWH is gaining more recognition worldwide within the academic and policymakers. However, in Nigeria, recognition of RWH as a reliable source of water within government circles is not strong enough to prompt policy statements or actions to prom

Abstract:

Att samla in regnvatten för att använda till olika syften har under de senaste åren blivit allt vanligare i flera länder. Denna metod är fördelaktig ur flera miljömässiga och samhällsekonomiska aspekter då den bidrar till minskad dricksvattenförbrukning och förbättrad dagvattenhantering. I Sverige är tekniken relativt obeprövad men flera stora byggnader där det ska implementeras är nu under byggnation. En av dessa är Celsiushuset i Uppsala där regnvatten ska samlas in på taket för att användas till toalettspolning. I dagsläget finns bristfällig kunskap om sådana system inom sektorn för samhäll

Abstract:

Construction sites are among the most common areas to experience soil erosion and sediment transport due to the mandatory foundation tasks such as excavation and land grubbing. Thus, temporary sediment barriers are installed along the perimeter to prevent sediment transport from the site. Erosion and sediment transport control measures may include, but not limited to, physical and chemical processes such as the use of a silt fence and polyacrylamide product. Runoff from construction sites and other impervious surfaces are routinely discharged into ponds for treatment before being released into

Abstract:

India is a country with progressing technical and economical development, but the development is not evenly distributed. Farmers in the Indian rural areas are struggling. There are worries that climate changes could have a negative impact on agriculture. This study was performed in Kancheepuram with support from the non-governmental organization Hand in Hand. The aims of this study were to analyze effects on agriculture due to watershed management in a village and to describe the crop patterns in a village and compare the yield with a village without watershed management. Data was collected by

Abstract:

Vattenbesparing och alternativa lösningar för att tillgodose vattenbehovet har blivit mer aktuellt de senaste åren med torka. Regnvatteninsamling för hushållsanvändning används redan på många platser runtom i världen men är begränsad i Sverige idag. Syftet är att dels undersöka en lämplig dimensionering av ett system för regnvatteninsamling för hushåll i Jälåsa och att identifiera olika drivkrafter och hinder. Metoden i denna studie har varit dels massbalans- och effektivitetsberäkningar för att se hur mycket regnvatten som kan samlas in och dels intervjuer med två teknikleverantörer och fem k

Abstract:

>Magister Scientiae - MSc<br>Previous studies have shown that the use of chloride mass balance (CMB) method is a suitable and practical approach to estimate groundwater recharge. This enables the prediction of groundwater availability to inform practical strategies for managing groundwater resources. However, such studies have largely applied the chloride mass balance method on national and catchment scales with limited focus on quaternary catchment level (QCL). Neglecting the chloride mass balance method at quaternary catchment level limits practical management and utilization of water resou

Abstract:

Infield rainwater harvesting (IRWH) technology has been used in arid and semi-arid parts of the world and promising results have been achieved in terms of increasing yield. The main aim of this study was to identify socio-economic factors determining the adoption of IRWH technology for enhancing household food security by smallholder farmers. The specific objectives were to assess the level of adoption of IRWH technology using descriptive statistics (mean, frequency and percentages). To determine socio-economic factors influencing adoption of IRWH technology, the binary logistic regression mod
