Irrigation land suitability assessment and mapping play an imperative role for sustainable utilization of scarce physical land resources. The objectives of this study were to prepare spatial data base of physical land resources for irrigated agriculture and to assess land suitability for irrigation and developing suitable area map for the study area. The study was conducted at Fogera catchment,...

Hyperspectral imagery (HSI) of the ocean-land interface, known as the littoral zone (LZ) can provide a valuable source of information for identification of underwater objects and materials, determination of water depth, and retrieval of water composition. The first step in the analysis is removal of atmospheric effects, resulting in surface reflectance spectra. The atmospheric removal is accomp...

This paper presents the performance of a water-to-refrigerant type ground source multi-heat pump (GSHP) system installed in a school building in Korea. The evaluation of the performance has been conducted under the actual operating conditions of the GSHP system. Ten units with the capacity of 10 HP each were installed in the building. Also, a closed vertical typed-ground heat exchanger with 24 ...

[1] We seek a better understanding of the distribution of subsurface ice on Mars, based on the physical processes governing the exchange of vapor between the atmosphere and the subsurface. Ground ice is expected down to 49 latitude and lower latitudes at poleward facing slopes. The diffusivity of the regolith also leads to seasonal accumulation of atmospherically derived frost at latitudes pole...

In coastal regions, the study of karst aquifers and the ground water resource exploitation require a specific methodology and exploration and monitoring techniques. Two directions are investigated, leading to new technological and methodological developments. The first investigation axis deals with the exploration of fresh water plumes from submarine karst springs. An Autonomous Underwater Vehi...

the paper presents the case study of the current formation of a brazilian pit lake from an iron ore mining activity. the water used for the filling of the lake comes from rain, ground water and the complementary pumpage from a close river. at its final stage, which will be reached around year 2018, lake aguas claras will have a surface area of 0.67 km2 and the depth of 234 m, which will make it...

sugarcane, which has high water requirements, is grown in khuzestan province (iran). climate and optimizing the use of water is very important to sustainable cultivation of sugarcane. studies of water requirements for sugar cane in khuzestan show that in parts of sugarcane agro-industry, the water applied is more than the actual water requirement of the plant. the present study was conducted to...

Humans are faced with serious problems due to the unfit fluoride levels in potable water, which cause skeletal and dental fluorosis. Therefore, correct information regarding fluoride level in water resources is important in community dentistry, however this data is missing at national level. The aim of this descriptive-analytical study was to explore and map fluoride dispersion patterns of grou...
