Long-term hydrologic simulations are presented predicting the effects of drainage water management on subsurface drainage, surface runoff and crop production in Iowa's subsurface drained landscapes.
However, processes of drainage inversion and drainage surface reduction occurred in the headwater of most rivers of the basin during the Late Pleistocene.
Foam longevity depends on the stability and is influenced by the following: surfactant concentration, salt concentration, solid/liquid adsorption, gas diffusion through foam films, gravitational drainage, surface forces, capillary forces, fluctuations (Klitzing and Müller 2002; Aronson et al. 1994).
This work aims to assess how Pleistocene glaciations modeled the landscape in the upper Senguer River basin and its relationship to current watershed features (drainage surface and fluvial hydrological regime).
CW can be used for the treatment of different types of wastewaters, that is, municipal, industrial, leachate, acid mine drainage, surface runoff, and so forth [ 10].
Previous field studies have shown that the hydrologic performance of bioretention cells varies greatly because of factors such as underlying soil type, physiographic region, drainage configuration, surface storage volume, drainage area to bioretention surface area ratio, and media depth.
For example, poor drainage causes surface runoff and soil loss, which are considered to be major causes of land degradation.
Peat landslides triggered by construction in upland areas demonstrate the importance of surface/subsurface drainage and surface loading in contributing to failure.
During mining, alternate drainage of surface wells was accomplished and the maximum gas drainage concentration of a single well could be up to 100%% for each surface well.
Phosphorus was mostly adsorbed in the soil, and its reduction was mainly affected by the soil drainage from surface runoff in summer.
