Precipitation is the most important component and critical to the study of water and energy cycle. In this study we investigated the propagation of precipitation retrieval uncertainty in the simulation of hydrological variables, such as soil moisture, temperature, runoff, and fluxes, for varying spatial resolution on different vegetation cover. Two remotely sensed rain retrievals were explored ...

Achieving compliance with the mandatory standards of the 1976 Bathing Water Directive (76/160/EEC) is required at all U.K. identified bathing waters. In recent years, the Fylde coast has been an area of significant investments in 'point source' control, which have not proven, in isolation, to satisfactorily achieve compliance with the mandatory, let alone the guide, levels of water quality in t...

The impairment of water quality by faecal pollution is a global public health concern. Microbial source tracking methods help to identify faecal sources but the few recent quantitative microbial source tracking applications disregarded catchment hydrology and pollution dynamics. This quantitative microbial source tracking study, conducted in a large karstic spring catchment potentially influenc...

Hydrological conditions determine the distribution of plant species in wetlands, where conditions such as water depth and hydrological fluctuations are expected to affect the interspecific interactions among emergent wetland species. To test such effects, we conducted a greenhouse experiment with three treatment categories, interspecific interaction (mixed culture or monoculture), water depth (...

In an attempt to provide a unified scheme for the simulation of changing behaviours of hydrological systems, a theoretical framework for stationary and non-stationary modelling is presented. The main triggers for hydrological change are reviewed, their impact on the long term properties of the inherent system are analysed and theoretical solutions are proposed for their representation. Model ca...

Targets for improvements in water quality entering the Great Barrier Reef (GBR) have been set through the Reef Water Quality Protection Plan (Reef Plan). To measure and report on progress towards the targets set a program has been established that combines monitoring and modelling at paddock through to catchment and reef scales; the Paddock to Reef Integrated Monitoring, Modelling and Reporting...

Back Propagation (BP) neural network, Widely adopted and utilized in automatic control, image recognition, hydrological forecasting and water quality evaluation, etc., as one of the Artificial Neural Networks, has stronger function and property of mapping, classification, functional fitting. This article takes the water flow of Lanzhou section of Yellow river in China as an example by the way o...

Ecosystem services are the benefits that people obtain from ecosystems (Brauman et al., 2007). Recognizing the importance of the services provided by ecosystems for human wellbeing is not a new idea, going as far as Plato (Feen, 1996) and the economic conceptualization of ecosystem values (Coase, 1960; Feen, 1996). However, the scientific and practical interests in assessing and trading ecosyst...

Qingyu Feng. M.S.A.B.E., Purdue University, December 2013. Biomass Production and Hydrological/Water Quality Impacts of Perennial Crop Production on Marginal Land. Major Professor: Indrajeet Chaubey. Marginal land has been proposed to be a viable choice for biomass production to meet the biofuel development goal set by Energy Independence and Security Act (EISA). However, very little informatio...
