Abstract Unsaturated flow is an important factor that affects groundwater motion. Among various drainage models, the nonlinear Hillslope‐storage Boussinesq (HSB) model has been commonly used to predict water flux along a slope. In this study, we improved by considering lateral in unsaturated zone. Using modified van Genuchten functions, analytically expressed concept of equivalent propagation thickness vadose This analytical expression was then incorporated into HSB reflect two different...
Abstract Recession flow analysis is usually conducted to infer hydraulic parameters of hillslope aquifers. Various Boussinesq equation‐based models, both linear and nonlinear, have been used analyze the recession curves for sloping aquifers, with a focus on long‐time behavior. Based modified equation capillarity incorporated, we demonstrate significant effect unsaturated curve, which result in three (instead two) power law regimes two transition points one) corresponding formation fully zone...
This article explores the cause of substrate clogging in absence suspended solids or very low (<<10mg/L, Water quality integrated wastewater discharge standard (GB189918-2002) level 1A emissions standards) influent during operation process. Both growth and detachment biofilm were found to play positive roles process under commonly used hydraulic loading vertical constructed wetland. In addition, existence enabled combine much easier, which accelerated settlement interception solids. The...
A conceptual model has been developed by using the parameter of influent suspended solids (SS) concentration to estimate clogging time in constructed wetlands (CWs). The depth layer is estimated through effective porosity vertically along CWs. basis predict lies fact that, when occurs, pore spaces were reduced and thus infiltration rate was reduced. group laboratory scale CWs employed develop validate its utilization. Good agreement between experimental data predicted obtained. This...
Abstract This paper presents an alternative Boussinesq equation considering hysteresis effect via a third‐order derivative term. By introducing improved moisture–pressure retention function, this describes, with reasonable precision, groundwater propagation in coastal aquifers subject to Dirichlet boundary condition of different oscillation frequencies. Test results confirmed that it is necessary consider horizontal and vertical flows unsaturated zone, because their variable influences on...
AbstractThis study analyzes the influence of a pre-dam reservoir on quality agricultural nonpoint source pollution. The results clearly indicated that under significantly improved water flowing through pre-dam. greatest reduction in pollutant concentration, particularly for suspended solids, NH4-N, and chlorpyrifos was observed settling area reservoir. this indicate pre-dams may be successfully applied to reduce pollution Taihu Lake basin. However, not able completely eliminate all...
Coastal wetlands are hotspots for nitrogen (N) cycling, and crab burrowing is known to transform N in intertidal marsh soils. However, the underlying mechanisms remain unclear. This study conducted field experiments used indoor control test devices investigate seasonal response of disturbance at sediment–water interface coastal tidal flat wetlands. The results showed that exhibited significant seasonality with large differences cave density depth. Due disturbance, fluxes were much greater...
Zhao, Z.; J.; Xin, P.; Jin, G.; Hua, G., and Li, L., 2016. A hybrid sampling method for the fuzzy stochastic uncertainty analysis of seawater intrusion simulations. The traditional requires hundreds or even thousands simulations to obtain a statistically stable result, which is significant challenge some nonlinear problems, such as simulating intrusion. (HS) was developed based on Monte Carlo (MC) whose input parameters are characterized by both variables numbers. HS restricted that fully...
