“…Hydrological models developed for watersheds usually ignore the exchange of water and nutrients between micro-and macropores. In this study, the MACRO model was used as some authors [7] have indicated the presence of macropores in peat soils.…”

“…Some authors [4][5][6] have reported that drainage of peat soils leads to decomposition of peat and increases fluxes of nutrients to watercourses. Drainage of peatlands results in peat oxidation and significantly changes their physical and chemical properties [7,8]. This can result in high nitrate-nitrogen (NO3_N) concentrations in the pore water of drained peatlands that is caused by the aeration of peat and subsequent mineralization and nitrification of organic N [9].…”

Abstract:Investigations have indicated that in addition to traditional sources, drained peat soils can be considered as a significant source of nitrogen in Estonia. This changes the measures to improve water quality in rivers. At present modelling of nitrogen in rivers has been concentrated on influence of agricultural activity. However, drained peat can increase nitrogen concentrations even without fertilization and farming activities. This investigation describes the attempt to model water quality in the watershed with large share of drained peat soils. A good alignment between measured and modelled nitrate concentrations using the MACRO and the SOILN for MACRO models was shown.

“…The Hula Valley, which is approximately 70 m above sea level, occupies the northernmost segment of the Jordan-Arava rift valley (see Fig. 1) (Litaor et al 2008). The precipitation period in the Hula Valley is relatively long compared to the rest of the country.…”

“…These flows were augmented from local springs, contributing approximately 63 hm 3 of water, out of the 448 hm 3 flowing in the Jordan River at the south end of the lake in an average year (Fohs 1936). The stronger and perennial western branch, the Jordan River, crossed the swamps and emptied into the lake Orshansky 1947, Hambright andZohary 1998), then continued through the basin, and emptied into the Sea of Galilee (Litaor et al 2008).…”

“…Following drainage, the peat exposed to air started decomposing and large environmental problems started to occur, including the release of large quantities of nutrients downstream (Avnimelech 1999). During the 1970s, a first series of water management steps were elaborated and implemented to prevent nitrate leakage from the Hula Valley (Litaor et al 2008), which led to reduction of both nitrate leakage from the region and influx into Lake Kinneret (Avnimelech 1999). The incessant decline in soil quality and fertility initiated a multi-disciplinary study that was conducted to stop the degradation of the peat soil and protect the Sea of Galilee from nutrient loads (Shaham et al 1990).…”

Response of water and energy exchange to the environmental variable in a desert-oasis wetland of Northwest China

et al. 2013

View full text Add to dashboard Cite

A case study on a desert-oasis wetland ecosystem in the arid region of Northwest China measured the seasonal and interannual variation in energy partitioning and evapotranspiration to analyse the response of water and energy exchange on soil moisture, groundwater, and environmental variables. Energy partitioning showed a clear seasonal and interannual variability, and the process of water and energy exchange differed significantly in the monthly and interannual scales. The net radiation was 7.31 MJ m À2 · day À1 , and sensible heat flux accounted for 50.42% of net radiation in energy fluxes, 40.56% for latent heat flux, and 9.02% for ground heat flux. The parameters in energy fluxes were best described by a unimodal curve, whereas sensible heat flux followed a bimodal curve. Variations in the daily evapotranspiration and crop evapotranspiration also exhibited a single peak curve with annual values of 569.84 and 644.47 mm, respectively. Canopy conductance averaged 20.77 ± 13.75 mm s À1 and varied from 0.16 to 83.96 mm s À1 during the two hydrological years. The variation in water and energy exchange reflected environmental conditions and depended primarily on vapour pressure deficit, net radiation, soil moisture, and water depth. Although the effects of precipitation on evapotranspiration showed that the response of this ecosystem to climate changes was not obvious, the variation of air temperatures had a strong influence on evapotranspiration, resulting in a significant increase in evapotranspiration (R = 0.730; P < 0.01). μ 2 , wind speed at 2-m height; ℧, decoupling factor 6102 B.
