Because of the Lack of water resources and the increasing water quantity used in living and production, the water resources are becoming the restrictive factor of regional economic and social development in in Manas river basin. The exploitation and utilization of conventional water resources has reached more than 95% in the basin,it caused great attention that the development and utilization of non-conventional water resources for agricultural development and ecological environment construction. At present, the exploitation and utilization of the non-conventional water resources(shallow underground salt water,saline water) for agriculture and forestry has become more and more widespread and in-depth. because of the lack of scientific instruction and reasonable exploitation, which not only caused water level falling, leading to degradation of the brittle natural entironment, but also caused SBHCSS and the decline in productivity. With the analysis of the non-conventional water resources actual exploitation and utilization, under the scientific development concept, the aryicle puts forward the sustained strategies of non-conventional underground water resources (salt water, saline water) reasonable exploitation and the irrigation return flow reuse efficient exploitation which is used for ecological restoration and reconstruction.

This paper describes recent developments related to a new return flow algorithm built into the Water Resources Management Model (WRMM) of Alberta Environmental Protection. An earlier return flow allocation method which was used in the WRMM did not always give satisfactory results. It was essential to fix this problem, since correct modelling of the return flows in overall river basin management is of crucial importance. The new return flow algorithm offers more reliable return flow allocation without detrimental effects on the overall model solution. This model is a major river basin planning tool in western Canada used to analyze responses of a river basin to varying operating policies or structural developments. It is a simulation model with a nested optimization subprogram. As a deterministic, steady state, and surface water allocation model, it normally relies on the estimates of natural flows and water demands throughout the river basin. The WRMM can provide quick simulations of any river basin with any number of components within a microcomputer environment. The model is used in ongoing river basin management studies in Alberta and other western provinces in Canada. Key words: water management, computer modelling, simulation, optimization, irrigation.

Natural water cycle is of river-basin characteristic, with obvious river-basin regularity in formation, movement and change. The development and utilization of river-basin water resources are of important significance to solve the shortage of water resources. Dagujia river is the second largest river in Yantai. But with fast development of social economy and population growth of Yantai city, Dagujia river resources have been overexploited, resulting in corresponding environmental effects. Based on the thorough investigation of the current water resources utilization, the paper analyses the production and the change trend of environmental effects and discusses projects and management mode in order to achieve efficient utilization of water resources.

The water resources is the necessary of human life and production, and also the main biological survival factors. In this paper, the Minqin basin water resources utilization, in Shiyang river basin.Minqin basin is one of the most serious areas, in China, the development and utilization of water resources angelica knot, the contradiction of the water and the ecological environment problems. Development and utilization of regional water more than its carrying capacity serious.Support the development of oasis and improve the ecological environment problems in Minqin basin, system analysis for the reasonable exploitation and utilization of groundwater need guarantee of rational use of water resources, and sustainable economic development and ecological environment of the benign circulation.

Water resources in the Yongding River basin (YRB) are one of the important fundamental conditions in supporting regional water conservation and ecological development. However, the historical changes in water resources under recent human activities remain unknown due to very limited observation data. In this study, terrestrial water storage anomalies (TWSA) as well as multiple precipitation and actual evapotranspiration products from satellites were collected, and the accuracy of the data was verified by observed data or pairwise comparisons. The TWSA during 1980-2016 was reconstructed by using the water balance method, and the reconstructed TWSA was verified using GRACE-observed TWSA, the average depth to groundwater in the Beijing Plain from historical document records and the observed runoff from Guanting Reservoir. The reconstructed TWSA data indicated that the significant decrease occurred during 2000–2016 and the average rate of decreasing trend was -11 mm/year, which may have been caused by a decrease in groundwater storage due to agricultural development. However, the reconstructed TWSA decreased slightly during 1980-1999. The establishment of the water storage deficit index (WSDI) showed that there was no drought or mild drought during 1980-1999; however, the water resource shortage during 2000-2016 was more serious due to groundwater storage decreases caused by agricultural development. The WSDI was verified by using the commonly used self-calibrated Palmer drought severity index. The findings are valuable for sustainable water resource management in the YRB.
