Samples were collected in 4 rainfall events in Jinan from May 2007 to Aug 2007.The purpose of this study is identification and characterization of hydrological process of urban runoff, as well as concentration variation of pollutants variation of pollutants in it .Hydrology and pollution of the rainfall-runoff process were analyzed on roof and road. Study results show that runoff coefficients of roof are 0.80~0.96, while 0.88~0.96 of road in Jinan. The shapes of hydrological curves of runoff are similar to rainfall curves but a milder tendency. The research that calculated the correlation between the slope of the pollutants come to the rainwater runoff of pollutants.So can have a detection of COD and SS and other major pollutants of storm water runoff in Jinan city to represent contents of other pollutants, greatly simplifies the rain run-off water quality testing and quantitative analysis.

Abstract: Firstly, the theory of groundwater quality set pair analysis and evaluation and the relative degree calculation methods were studied. Secondly, groundwater quality set pair analysis and evaluation model was built and applied to the groundwater quality evaluation in Taiyuan. Based on the measured data ,the groundwater quality classification was calculated. It is shown through comparison analysis that the present results are the same as the results from other methods. Moreover, the present method has the advantages of simplification, reliability and high calculation efficiency.

The irrigated area should be considered in the design of a drip irrigation system (DIS) because it pre-eminently influences the DIS investment and running cost. The effects of the irrigated area on the working discharge and head of upstream installations of the DIS, system operation cost, field management for rotation irrigation, and water safely supply for crops were analyzed in this paper with the theory of design DIS. The results indicated that with the expansion of irrigated area, the working discharge and head of the upstream installations would be increased as well as the system operation cost, and the rotation irrigation management became difficult due to a short time for water application for crops, furthermore, the crops couldn’t be ensured in irrigation.

Based on two dimension hydraulic design code PCAD2004, the method on three dimension parameter sculpting of double channel pump impellers is researched. With the Pro/TOOLKIT flat roof and using VC++6.0, the second development is done on Pro/E and the three dimension parametric software of double channel pump impellers is successfully developed for the first time. The practical application indicates that the program runs well and the results can meet the engineering needs.

Numerical simulation of cavitation in axial-flow pump under large-flow condition has been conducted by calculation Eulerian-Eulerian homogeneous model and Navier-Stokes equation with RNG turbulence model in this paper. The analysis of simulation results explains the main sources of bubble in flow of axial-flow pump and predicts the assembly and region that happened cavitation and cavitation erosion and opens out the relationship beween pressure and cavitation areas of the back of impeller. Respective comparation of the head and efficiency confirms the stage of cavitation and this is good for the operation of axial-flow pump running.

The emulation analysis on the temperature and stress field during the construction of U aqueduct is made with the transient analysis of 3-D FEM for the simulation of the actural placement of U aquecuct in layers. The results manifest: because the layer is thin, the temperature quickly arrived at steady temperature field. The stress due to temperature is mainly external restraint and result is little, so it is difficult to create crack on the aqueduct.

Water price is a basic tool in water management, and the key point is how to “get the price right”. In this paper, we analyses the formation of water price under different water demand and supply. And found that different pricing methods have different performance in cost compensation, social benefit and benefit distribution. The results show, when water market is equilibrium, the water suppliers’ benefit and users’ benefit is maximum as long as the water price is equal to marginal cost, which is also equal to marginal benefit of water. If the water market is unequilibrium, the price be tween the marginal cost and marginal benefit would achieve social benefit maximum, but the benefit distribution between suppliers and users would be different as price changing. When come to the cost compensation, things are different, when the demand for the water is low, or the water market is unequilibrium, the price, which could achieve the social benefit maximum, may not compensate the cost of water supply. Without regard to the government regulation, the cost of water supply must be compensated, or there is no water supplier, and also the suppliers want to maximize their own benefit. From this perspective, the final price of water is equal to the marginal benefit of water when the implementation cost is not considered.
