Schistosomiasis is a parasitic disease mostly found in areas along the Changjiang River, Oncomelanias is the only intermediate host of schistosomiasis. Oncomelania entering into farmland or the residential zones through the flood discharge or irrigation system is the main reason of spreading schistosomiasis. Therefore it is most essential and effective way to control diffusion of oncomelanias a...

This paper is concerned with the quantification of the likely effect of anthropogenic climate change on the water resources of Jordan by the end of the twenty-first century. Specifically, a suite of hydrological models are used in conjunction with modelled outcomes from a regional climate model, HadRM3, and a weather generator to determine how future flows in the upper River Jordan and in the W...

Abstract We describe our work in developing decision support tools to manage large international rivers. This is a complex environmental decision making problem due to the presence of multiple objectives stemming from multiple uses of the reservoirs (energy production, irrigation, flood protection, ), several sources of uncertainty (inflows, water demand, evaporation, ), long-term effects of de...

To estimate the amount of evapotranspiration in a river basin, the "short period water balance method" was formulated. Then, by introducing the "complementary relationship method," the amount of evapotranspiration was estimated seasonally, and with reasonable accuracy, for both small and large areas. Moreover, to accurately estimate river discharge in the low water season, the "weighted statist...

the current study assessed the climate change impacts on land productivity of major food and non-food grain crops in india. we compiled panel data for 30 years (1980-2009) using fifteen crops across thirteen agriculture intensive states. the value of production for each crop is estimated by farm harvest price (at constant prices, 1993-1994). aggregate value of production on per hectare land is ...

While in the field of hydrology remote sensing techniques are often applied and well accepted there is still a deficit in the use of remote sensing techniques in the field of planning, design and operation of water resources systems. It is the aim of this paper to overcome this deficit and encourage water managers to use remote sensing techniques more widely. In order to achieve this, several s...
