Integrating the analysis of natural and social systems to achieve sustainability has been an international scientific goal for years (1, 2). However, full integration proven challenging, especially in regard role culture (3), which is often missing from complex equation. To enact policies practices that can sustainability, researchers policymakers must do a better job accounting culture, difficult though this task may be.
Soil erosion from agricultural fields is a fundamental water quality and quantity concern throughout the U.S. Watershed models can help target general areas where soil conservation measures are needed, but they have been less effective at making field-level recommendations. The objectives of this study were to demonstrate method field-scale targeting using ArcSWAT assess impact topography, soil, land use, management source data on results. was implemented in Black Kettle Creek watershed...
For almost 30 years, the Soil and Water Assessment Tool (SWAT) has been successfully implemented to address issues around various scientific subjects in world. On other hand, it reaching limit of potential flexibility further development by current structure. The new generation SWAT, dubbed SWAT+, was released recently with entirely coding features. SWAT+ is designed have far more advanced functions capacities handle challenging watershed modeling tasks for hydrologic water quality...
Stability analysis of gravity‐driven unsaturated flow is examined for the general case Darcian with a generalized nonequilibrium capillary pressure‐saturation relation. With this relation governing equation referred to as Richards (NERE). For special where vanishes, NERE reduces (RE), conventional describing flow. A linear stability RE shows that unconditionally stable and therefore not able produce unstable flows infinitesimal perturbations field. much stronger result unconditional derived...
Freezing of unsaturated soils is associated with the formation a moving freezing zone and liquid water flow toward zone. An equilibrium thermodynamic formulation coupled heat transport in variably saturated partially frozen porous media developed self‐similar solution derived for case semi‐infinite horizontal column constant temperature on one boundary. Solutions to equations are using Runge‐Kutta procedure. The found yield two possible modes distinguished by zones composed different...
<abstract><title><italic>Abstract.</italic></title> Ephemeral gullies (EGs) are incised channels resulting from concentrated overland flow that often form in a similar location every year. These erosional features add to producersâ management efforts and costs. Locating EGs predicting their length is crucial for estimating sediment load planning conservation strategies. Since topography plays an important role the formation of EGs, this study investigated prediction EG two agricultural...
Abstract Alteration of flow regimes due to change in climate and its potential impact on habitat species has become a major cause concern for riverine ecosystems. Areas that are more vulnerable such changes semiarid river systems or regions experiencing intermittent cyclic droughts. Although ecological expected occur with regime alterations, the biological cannot be predicted until is analysed. This study addresses this by providing an analysis basin Central Great Plains from 50 100‐year...
Sustainability has been at the forefront of environmental research agenda integrated anthroposphere, hydrosphere, and biosphere since last century will continue to be critically important for future science. However, linking humans environment through effective policy remains a major challenge sustainability practice. Here we address this gap using an agent-based model (ABM) coupled natural human systems in Smoky Hill River Watershed (SHRW), Kansas, USA. For freshwater-dependent agricultural...
Abstract Ground heat flux ( G 0 ) is a key component of the land‐surface energy balance high‐latitude regions. Despite its crucial role in controlling permafrost degradation due to global warming, sparsely measured and not well represented outputs scale model simulation. In this study, an analytical transfer tested reconstruct across seasons using soil temperature series from field measurements, Global Climate Model, climate reanalysis outputs. The probability density functions ground...
Climate change impacts watershed hydrology and contributes to alteration of hydrologic regimes in streams. However, global climate models (GCMs) operate at spatial temporal scales that are too large capture important watershed-scale shifts. A method disaggregating monthly ensemble GCM data into temperature precipitation series for daily, watershed-specific simulations with SWAT was developed assessed the Soldier Creek northeast Kansas. stochastic weather generator (WINDS) employed produce a...
Watershed models have been widely used to estimate soil erosion and evaluate the effectiveness of conservation practices at different temporal spatial scales; however, little progress has made in applying these theoretical model results practical challenge allocating practice funding meet specific loss objectives.
