This paper analyzes the evolution of the concept of Integrated Water Resources Management (IWRM) at international conferences over the past three decades and addresses the prospects of IWRM in resolving the current water crisis. It also identifies seven crucial challenges to implementing IWRM. Our rivers and aquifers are the life-blood of the planet. To achieve sustainable development, we must ...

A dual frequency ground-based radiometer operating in the 1 to 1.4 cm wavelength range can provide continuous measurements of integrated water vapor and cloud liquid water. Using climatological data, the accuracy of the vapor and liquid determinations is estimated as a function of cloud amount. Limiting factors in the water determination are uncertainties in water vapor absorption coefficients ...

Ozonation-biofiltration as an integrated process for low pressure membrane (LPM) pre-treatment appears quite promising. It has recently been demonstrated to successfully reduce membrane fouling and the combined process is able to produce high quality water, provide robustness, and produce water which consistently meets strict regulations. However, this integrated technology is neither commonly ...

In large canal irrigation project areas, integrated management of surface and groundwater resources can improve water use efficiencies and agricultural productivity and also control water logging. Such integrated management requires an estimation of spatial distribution of recharge and ground water flow in the underlying aquifer. Recharge occurs both as percolation losses from fields and seepag...

irrigated agriculture is an important contributor to the expansion of national food supplies and is expected to play a major role in food security of developing countries. such countries face water crisis for securing the food staples. well designed water resource policies potentially can improve the water allocation and use efficiency as well as the food security objectives. this paper present...

Decision support tools that aim to assist efficient integrated water resources management should integrate the multiple, interdependent uses of water. There exist, however, few models that assess the trade-offs between environmental and socio-economic impacts of water management changes in an integrated framework. This paper presents a model that integrates hydrological, ecological and economic...
