Supraglacial channel networks link time varying melt production and meltwater routing on temperate glaciers. Such channel networks often include components of both surface transport in streams and subsurface porous flow through near-surface ice, firn or snowpack. Although subsurface transport if present will likely control network transport efficacy, it is the most poorly characterized componen...

a greenhouse experiment was conducted during the growing seasons (2008/2009 and 2009/2010) to investigate the effects of water quality and soil amendments, irrigation methods and rates on tomato (solanum lycopersicon l. cv. red gold) yield and water use efficiency (wue). irrigation management treatments were fresh (0.86 ds m-1) and saline waters (3.6 ds m-1), surface and subsurface irrigation m...

This paper presents the results of research on the antibiotic sensitivity of bacteria inhabiting the surface microlayer (SM) and the subsurface water (SSW) of Lake Jeziorak Mały. It follows from the results that doxycycline, oxytetracycline and nalidixic acid are characterized by the strongest antibacterial effect. For some antibiotics, different strengths of the effect on bacteria isolated fro...

this research was designed to evaluate and compare the applicability of two different types of irrigation including traditionally (surface irrigation) and simple sub-surface drip irrigation (using pricked-pipe covered with plastic cloth). two plots containing 39 pistachio trees with 720 m2 area were selected in rafsanjan, iran. both plots were irrigated using exactly the same quantity and quali...

Subsurface agricultural drainage has allowed for enhanced crop production in many areas of the world including the upper Midwest, United States. However, the presence of nitrate-nitrogen (nitrate-N) in subsurface tile drainage water is a topic of intense scrutiny due to several water quality issues. Many studies have been conducted looking at ways to reduce nitrate-N in tile drainage (Baker et ...

Analysis of subsurface stormflow from 147 storms at the 20 m long trench in the Panola Mountain Research Watershed by Tromp-van Meerveld and McDonnell (2006a) showed that there was a distinct 55 mm precipitation threshold for significant subsurface stormflow production. This second paper in the series investigates the processes responsible for this threshold response. We installed a dense spati...

Introduction: Estimates of the global inventory of water on Mars based on a determination of the amount of water required to erode the outflow channels suggest that a quantity equivalent to a global ocean 0.5 to 1 km deep may be stored in the planet’s subsurface [1, 2]. As this inventory post dates the timing of the most efficient processes that may have lead to its removal, the majority of thi...
