The conventional practices of urbanization significantly increase the flooding and water pollution. This is due to reduction in pervious areas. To minimize the problem, various concepts of low impact development have been implemented such as underground bioretention cells. The main intention of this research was to review different aspects of Low Impacts Developments (LIDs) especially bioretention cells and develop a hydraulic model to predict the distribution of runoff throughout the bioretention cell under different scenarios. In this study, the hydraulic simulation model was developed in Matlab in order to attain better understanding of bioretention systems. The hydraulic model was used to investigate the impacts of different design options on the distribution of flows over the entire bioretention cell. Understanding the effect of design options can be beneficial to improve the performance of bioretention systems and improving the water quality and quantity in developed areas.

Ganjiang River Basin

Using the contingent valuation method and the Heckman two-stage model, we explore residents’ willingness to accept (WTA) compensation and their WTA level for ecological conservation compensation in the upstream of the Ganjiang River Basin in China. The findings reveal that 86.26% of the respondents are willing to accept compensation, and the average compensation level is ¥789.60/household per year. The residents’ gender, annual disposable income, residential location, decision on whether or not the watershed environment is important, and their satisfaction with water quality and quantity are significantly related to their WTA. The influencing factors that significantly affect compensation level are residents’ occupation, educational background, annual disposable income, family size, residential location, decision on whether or not the watershed environment is important, and their satisfaction with water quality and quantity. The results of this empirical research have important policy implications: the government should strengthen advocacy and education of watershed ecological environment protection, intensify farming and other agricultural activities, establish a differentiated and diversified compensation strategy, so as to protect and improve the ecological environment of the Ganjiang River Basin.
