One of the most important factors for appropriate performance of subsurface drainage systems is having adequate discharge for drains. For this purpose, knowledge about effect of drainage parameters change on drain discharge is essential in subsurface drainage systems. In this article, using change all of the drainage parameters by EnDrain software, changes of drains discharge has been investiga...

in tunisia, kalâat el andalous irrigated district is one of the most affected areas by salinization. the objective of this study was to predict the root zone salinity (over 10 years) in this area using the saltmod simulation model for subsurface drainage system. saltmod is based on water balance, salt balance model, and seasonal agronomic aspects. in the pilot area, irrigated vegetables crops s...

Objective] Recently, the effectiveness of closed wound drainage has been evaluated for various types of orthopedic surgery. Some studies showed insufficient evidence to support the routine use of a drain. In the current analysis, the efficacy of closed suction drainage in anterior spinal fusion for lumbar spinal tuberculosis was retrospectively evaluated. [Patients and Methods] Ninety-one conse...

INTRODUCTION: Chronic subdural hematoma (CSDH) is a cause of significant morbidity and mortality which is often amenable to surgical drainage. The majority of patients recover rapidly after surgical intervention, but 5% to 30% experience recurrence. Although the use of drains after burr hole evacuation may lower recurrence, they are not used routinely because of a lack of evidence showing effic...

Marine protected areas worldwide limit harvest to protect sensitive fisheries, but rarely do they address water quality goals that may have equally demonstrable impacts. California has over 500 coastal shoreline miles of marine protected areas designated as Areas of Special Biological Significance (ASBS), but receives untreated wet weather runoff discharges from over 1600 storm drain outfalls. ...

Background/Introduction Pneumothorax can be a complication following chest drain removal. In thoracic surgery, access to the pleural cavity involves a pleurotomy. A chest drain is inserted to allow re-expansion of the lungs post-pleurotomy. This also prevents a tension pneumothorax. Some patients have a residual pneumothorax post-chest drain removal noted on chest radiography. Rates of pneumoth...

This paper presents results from an extensive experimental study on hydraulic performance of new rectangular bridge deck drains developed by the Texas Department of Transportation (TxDOT) Bridge Division. It fits between the deck reinforcement with the top of the drain flush with the bridge surface and does not interfere with the structural connection of the bridge rail to the deck. Experiments...
