A project designed to gain access to all usable data to aid construction of 3D geological models for southern Manitoba has included signifi cant effort to appropriately utilize lithological data of variable quality in the Provincial water well database known as “GWDrill”. In order to use the data, it was necessary fi rst to assign x, y, and z coordinates to each site on the basis of the existin...

In this paper we consider system identification of irrigation channels. The results in this paper extend previous work in several important aspects. Both undershot and overshot gates are treated, and the overshot gates operate under both free and submerged flow. The models are estimated and validated on operational data from the Coleambally Main Channel in Australia, and the obtained system ide...

AQPs are water channel proteins. In particular, AQP1 was demonstrated to be involved in cell migration. According to the model proposed by Verkman and collaborators, AQP drives water influx, facilitating lamellipodia extension and cell migration. Investigating the possible connection between AQP1 and cytoskeleton, our group showed that such a water channel through Lin7/beta-catenin affects the ...

We compare the use of multi-criteria decision analysis (MCDA)-or more precisely, models used in multi-attribute value theory (MAVT)-to integrated assessment (IA) models for supporting long-term water supply planning in a small town case study in Switzerland. They are used to evaluate thirteen system scale water supply alternatives in four future scenarios regarding forty-four objectives, coveri...

People’s participation is a buzz word in the development agenda of the national and international agencies. In the governance of water also this concept has got central role in planning, implementation and running of the projects. The process is not a linear one rather than a pluralistic strategy including the state, civil society and the local community, to include the ‘people’s voice’ in deve...

The small size of Na(+) and Cl(-) ions provides a bottleneck in desalination and is a challenge in providing alternatives for continuously depleting fresh water resources. Graphene by virtue of its structural properties has the potential to address this issue. Studies have indicated that use of monolayer graphene can be used to filter micro volumes of saline solution. Unfortunately it is extrem...

In Ethiopia, the most common method of disposal of waste water is by land spreading. This treatment method has numerous problems, namely high labor requirements and the potential for eutrophication of surface and ground waters. Constructed wetlands are commonly used for treatment of secondary municipal wastewaters and they have been gaining popularity for treatment of agricultural wastewaters i...

An adequate method for the safe disposal oi human excreta is perhaps the most important problem which confronts rural sanitarians and public health workers. With the recognition of water as the carrier of many of the filth-borne diseases, more emphasis has been laid in recent years on the extent of soil and ground water pollution in deciding the sanitary and health protective values of these me...

This is a clear and well written paper that provides a detailed account of laboratory experiments of water vapor release from a collection of different biomass fuel types. The results from 16 experiments conducted in a combustion chamber show the amount of water vapor released as a ratio to the CO/CO2 combustion efficiency. This paper provides a nice contribution to the fire sciences community ...

Spaceborne radar interferometric delay measurements were used to infer high-resolution maps of integrated atmospheric water vapor, which can be readily related to meteorological phenomena. Maps of the water vapor distribution associated with a precipitating cloud, a partly precipitating cold front, and horizontal convective rolls reveal quantitative measures that are not observed with conventio...
