Catchment classification is an efficient method to synthesize our understanding of how climate variability and catchment characteristics interact to define hydrological response. One way to accomplish catchment classification is to empirically relate climate and catchment characteristics to hydrologic behavior and to quantify the skill of predicting hydrologic response based on the combination ...

Evolution of the concentration of aerosols with a diameter less than 10 µm (PM 10) measured in central Rondônia in a pasture site during September to No-vember 2002. The arrows indicate the first significant rainfall on October 7 and the onset of regular rainfall in the beginning of November. Data from LBA/Smoke, Aerosols, Clouds, Rainfall and Climate (SMOCC) Project. See article on page 4. Rat...

The transferability of hydrologic models is of ever increasing importance for making improved hydrologic predictions and testing hypothesized hydrologic drivers. Here, we present an investigation into the variability and transferability of the recently introduced catchment connectivity model (Smith et al., 2013). The catchment connectivity model was developed following extensive experimental ob...

The main intent of this paper is to present a review on the application of time series analysis techniques in hydrology and climatology. An overview of various statistical tests for detecting and estimating the hydrologic time series characteristics (i.e., homogeneity, stationarity, trend, periodicity, and persistence) is presented, together with their merits and demerits followed by comprehens...

This paper outlines and demonstrates a strategy for coupling of integrated hydrologic model and Geographic Information System (GIS) to meet pre/post processing of data and visualization. Physically based fully distributed integrated hydrologic models seek to simulate hydrologic state variables and their interactions in space and time. The process requires interaction with a range of heterogeneo...

[1] Many current metrics of drought are derived solely from analyses of climate variables such as precipitation and temperature. Drought is clearly a consequence of climate anomalies, as well as of human water use practices, but many impacts to society are more directly related to hydrologic conditions resulting from these two factors. Modern hydrology models can provide a valuable counterpart ...

Hydrologic regime plays a major role in structuring biotic diversity within river ecosystems by controlling key habitat conditions within the river channel and floodplain. Daily flow records from seven hydrological stations and the range of variability approach were utilized to investigate the variability and spatial pattern of the hydrologic alterations induced by the construction of the Three...

Interactions between surface and groundwater systems are well-established theoretically and observationally. While numerical models that solve both surface and subsurface flow equations in a single framework (matrix) are increasingly being applied, computational limitations have restricted their use to local and regional studies. Regional or watershed-scale simulations have been effective tools...

Middle and lower Hanjiang River (MLHR) basin, China. Changes in streamflow are often due to intertwined factors like climatic variability, land use change, hydraulic constructions, whose relative impact is however poorly understood. In this study, we disentangled these effects by comparing real data modelled scenarios of catchment behaviour. Modelled employ the soil water assessment tool (SWAT)...

[1] The ability to map relationships between ecological outcomes and hydrologic conditions in the Everglades National Park (ENP) is a key building block for their restoration program, a primary goal of which is to improve conditions for wading birds. This paper presents a model linking wading bird foraging numbers to hydrologic conditions in the ENP. Seasonal hydrologic statistics derived from ...
