Abstract:China is the largest country in terms of population and its booming urbanization has exerted negative effects on ground-surface hydrological processes at different spatial scales, land-use types, and water balance, such as surface runoff, groundwater recharge, and evapotranspiration. However, it is not yet well understood as to how the modifications of the spatial patterns of landscapes affect the water balance on a regional scale. In this study, the water and energy transfer among soil, plants, and atmosphere (WetSpass) model was applied to evaluate the urbanization effects on the water balance on a regional scale by using Beijing as the case city for this current study. The relationships among impervious surfaces, landscape pattern indices, and water balance components were also quantified. Results indicated built-up land in 2012 was 673 km 2 larger than it in 2000, mostly converted from croplands. WetSpass model also indicated the variation rates of annual average surface runoff, evapotranspiration and groundwater recharge were 7%, 0.4% and −2% in the whole Beijing area, while they reached 52%, 6% and −24% in the urban area of Beijing from 2000 to 2012, respectively. At a city scale, four districts-Dongcheng, Xicheng, Chaoyang, and Haidian-were characterized by higher impervious percentage, as reflected by lower groundwater recharge and higher surface runoff than other districts. At quadrat scale, however, groundwater recharge (surface runoff) was negatively (positively) correlated with impervious percentages. For landscape indices, the Aggregation Index was positively correlated with surface runoff and negatively correlated with groundwater recharge while Patch Density Index, Splitting Index, Patch Richness Density Index, and Shannon's Diversity Index presented opposite relationships. The results of this study can help to develop human knowledge about the impacts of urbanization on hydrological cycles on a regional scale.

Since the Open Geospatial Consortium (OGC) proposed the geospatial Web Processing Service (WPS), standard OGC Web Service (OWS)-based geospatial processing has become the major type of distributed geospatial application. However, improving the performance and sustainability of the distributed geospatial applications has become the dominant challenge for OWSs. This paper presents the construction of an elastic parallel OGC WPS service on a cloud-based cluster and the designs of a high-performance, cloud-based WPS service architecture, the scalability scheme of the cloud, and the algorithm of the elastic parallel geoprocessing. Experiments of the remote sensing data processing service demonstrate that our proposed method can provide a higher-performance WPS service OPEN ACCESSSustainability 2015, 7 14246 that uses less computing resources. Our proposed method can also help institutions reduce hardware costs, raise the rate of hardware usage, and conserve energy, which is important in building green and sustainable geospatial services or applications.

“…Bacu et al (2013) developed gSWAT application which allows many users to access and use the computational resources provided by Grid infrastructure in the calibration process of a complex Soil Water Assessment Tool hydrologic model using a web-based environment. Additionally, some researchers focused on designing WebGIS-based systems such as a hydrograph analysis tool (Lim et al, 2005), a rainfall-runoff model (Jia et al, 2009) and a flood-forecasting system (Al-Sabhan et al, 2003;Kulkarni et al, 2014). These web-enabled applications certainly provide a lot of supports to the users.…”

Abstract:The objective of this study is to develop an open access web-based conceptual Xinanjiang model for supporting calibration process with user-friendly interfaces. This makes it possible to calibrate the model for any user irrespective of the location, resource availability or technical capability. This interface not only allows the user to run the model in a user-friendly environment, but also provides useful support for better calibration by suggesting parameter settings based on observed hydro-climatic data, calculating Nash-Sutcliffe efficiency at daily, monthly and annual scales using time series of observed and simulated discharge data for every successful model run and hydrograph visualization. Moreover, the user can further verify the agreement between the observed and simulated discharge by visually inspecting the hydrograph. The interface allows rendering hydrographs using simulated and observed discharge for a respective model run or group of model runs. The user can perform repeated model runs with different parameter sets until it achieves a satisfactory accuracy. The user can download the result and parameter files for all or any specific model run.
