A mixed-model moving-average approach to geostatistical modeling in stream networks. Ecology 91:644–651. A distance matrix that contains the hydrologic distance between any two sites in a study area is needed to fit a geostatistical model using the tail-up and tail-down autocovariance functions. However, the hydrologic distance information needed to model the covariance between flow-connected a...

Early life events influence vulnerability to psychiatric illness. This has been modelled in rats and it has been demonstrated that different durations of maternal separation shape adult endocrine and behavioural stress reactivity. One system through which maternal separation may act is the locus coeruleus (LC)-norepinephrine system that regulates emotional arousal. Here we demonstrate that diff...

325 Land hydrologic responses to meteorological forcing involve complicated exchanges of moisture and energy between soil, vegetation, snowpack, groundwater, and the overlying atmospheric boundary layer. These exchanges occur in the form of many interactive natural hydrologic processes, including precipitation, snow and soil water melting and freezing, infi ltration, storage and movement of soi...

In this study both data of land use and cover were compared for selected period time it is obvious that urban area significantly increased in Saline River watershed, Arkansas, USA. For hydrologic studies analysis WMS 8.1 program was used to delineate the watershed other processes. further analysis, HEC-HMS analyze results hydrographs peak flows. Results show there impact processes due urbanizat...

soil and water assessment tool model, swat, uses different layers of watershed data which out of soil layer is the important one. soil layer data should be extracted from detailed soil maps. in most developing countries including iran, these detailed maps are not available except for irrigation districts and rarely for dry land farming areas and also for some strategic places of development pur...

This study was part of a project designed to simulate the long-term landform equilibrium rehabilitated mine site. The utilized event Fine Suspended Sediment (FSS) fluxes in receiving stream following rainfall as an indicator stability. aim this use HEC-HMS determine sediment and discharge quantity upstream how it affects downstream development catchment landform, terms changes geomorphology. Th...

This paper presents a procedure for standard application of hydrologic ⁄water quality models. To date, most hydrologic ⁄water quality modeling projects and studies have not utilized formal protocols, but rather have employed ad hoc approaches. The procedure proposed is an adaptation and extension of steps identified from relevant literature including guidance provided by the U.S. Environmental ...

Although arsenic contaminated groundwater in Bangladesh is a serious health issue, little is known about the complex transient patterns of groundwater flow that flush solutes from aquifers and carry solutes into the subsurface. Hydrologic modeling results for our field site in the Munshiganj district indicate that groundwater flow is vigorous, flushing the aquifer over time-scales of decades to...
