This paper presents the development of a rainfalltriggered landslide module within an existing physically based spatially distributed ecohydrologic model. The model, tRIBS-VEGGIE (Triangulated Irregular Networks-based Real-time Integrated Basin Simulator and Vegetation Generator for Interactive Evolution), is capable of a sophisticated description of many hydrological processes; in particular, ...

Pesticides applied to turf grass have been detected in surface waters raising concerns of their effect on water quality and interest in their source, hydrological transport and use of models to predict transport. TurfPQ, a pesticide runoff model for turf grass, predicts pesticide transport but has not been rigorously validated for larger storms. The objective of this study was to determine Turf...

Water quality impacts due to non-point source pollution can be significant particularly in environmentally sensitive areas. They may, however, be difficult to quantify, since the magnitude is heavily influenced by climatic, geomorphologic, lithologic and pedologic characteristics. A conceptual model for continuous daily simulation is proposed to reproduce the quali-quantitative response of a Si...

purpose: to assess various aspects of integrating a virtual reality (vr) simulator in the training of ophthalmology residents methods: in this qualitative study, some aspects of the vr eyesi simulator as a health technology were assessed. data was collected using a multiple-choice questionnaire and several deep interviews addressed to users and administrators of simulator training. face and con...

Measurements of chlorothalonil residue on tomato foliage are expensive and time consuming, yet knowledge of chlorothalonil persistence would assist in fungicide application scheduling. The objective of this study was to calibrate an existing chlorothalonil persistence model for processing tomatoes, and to incorporate the predictions of chlorothalonil residue into TOM-CAST. The Bruhn and Fry (19...

Estimation of changes in crop yields is currently based on projections of atmospheric General Circulation Models (GCM) and the use of crop simulators. Crop simulators require daily input of environmental variables. GCMs produce monthly projections of climatic variables. Our objective was to explore the possibility of using monthly weather projections in yield estimates. We considered atmospheri...

Dripping rainfall simulators are important instruments in soil research. However, a large number of non-standardized have been developed, making it difficult to combine and compare the results different studies which they were used. To overcome this problem, is necessary become familiar with design performances current simulators. A search has conducted for scientific papers describing dripping...

Measuring the characteristics of raindrops is essential for different processes studies. There have been many methods used throughout history to measure raindrops. In recent years, automatic image recognition and processing systems with high-speed cameras characterize rainfall by obtaining spectrum droplet sizes their speeds thus being able use this technology calibrate simulators. work, two ph...

A method was developed that employs thin boards (0.56 m) comprising different paving materials (2 asphalt types and concrete) typically used in urban environments. Boards can be placed at various locations of interest within an urban catchment to investigate accumulation of contaminants over specified periods of time. Boards are then placed under a rainfall simulator in order to generate runoff...

Numbers of greenroofs in urban areas continue to grow internationally; so designing greenroof soil to reduce the amount of nutrients in the stormwater runoff from these roofs is becoming essential. This study evaluated changes in extensive greenroof water discharge quality and quantity after adding biochar, a soil amendment promoted for its ability to retain nutrients in soils and increase soil...
