Resumen

Methane (CH4) flux was measured from undrained, drained, and ditched portions of treed fen, forested bog, and treed bog sites in the Wally Creek experimental drainage site (near Cochrane, Ontario), from May to October 1991. Drainage for 7 years lowered the water table from between −21 and −49 cm to −41 and −93 cm at the three respective sites. Drainage resulted in a conversion of the peatlands from a CH4 source (0 to 15 mg CH4 •m−2 •d−1) to a small CH4 sink (0 to −0.4 mg CH4 •m−2 •d−1). In contrast, CH4 efflux from the ditches ranged from <5 to >400 mg CH4 m−2 •d−1. The flux data were used to estimate the impact of forest drainage practices on net CH4 emissions from a forest drainage complex. For the treed and forested bogs, there was a net increase in CH4 emissions where ditch spacing was closer than 38 m. Even with very close ditch spacing (>12 m), there was a net decrease in CH4 flux from the treed fen. The results of this study indicate that the combination of low antecedent CH4 fluxes from an undrained peatland, and moderate fluxes from the drainage ditches, will produce a net increase in CH4 emissions from forest drainage.

Resumen

Methane fluxes were measured from ditches on peatlands drained for different purposes in two testing areas in European part of Russia. We used static chamber method and gas chromatography for CH 4 analysis. In Moscow Oblast CH 4 emissions were measured from ditches on milled peat extraction area and on agricultural drainage area (used for haying) during 2005-2011. Ditch spacing for both sites is 40 m, width on water level – 1.5-2 m. Averaged (median) methane flux for summer period was 28.5 and 12.5 mgС-CH 4∙m –2∙h –1, respectively, at these sites. Averaged (median) methane flux for summer period was 28.5 and 12.5 mgС-CH 4∙m –2∙h –1 for these sites consequently. In 2009-2011 methane fluxes were also measured from the ditch on forest drainage area, upstream and downstream the dam built for mire restoration. Simple average CH 4 emission rate was much higher at tail-bay point with flowing water as compared with back point upstream the dam with stagnant water – 14.4 and 2.4 mgС-CH 4∙m –2∙h –1, consequently. We assume water flow rate supports water degassing and increase of CH 4 emission from ditches. In Tver Oblast methane flux was measured in 2010 from ditches on forested bog and on forested fen, both drained for forestry with ditch spacing approx. 100 m, and ditch width on water level – 1-1.5 m. Flux observed at first nutrient-poor site was much lower – 0.31 mgС-CH 4∙m –2∙h –1, as compared with nutrient-rich one – 3.88 mgС-CH 4∙m –2∙h –1. Using methane emission rates from ditches and fractional area of ditches we calculate emission factors from drained peatlands. The results showed rather high values which need to be considered while assessing GHG emissions from drained peatlands.

Resumen

Abstract. Poor maintenance, environmental concerns, land use changes, and adaptation to climate change are creating a growing need for better agricultural drainage. The objectives of this study were to identify ditch properties that can be evaluated visually on-site and related soil erosion processes, and to define parameters requiring more intensive study and estimate these using simplified methods. The study included surveys of ditches in various soils using MADRAS (Minnesota Agricultural Ditch Research Assessment for Stability) to classify ditch status. To explain why some ditch segments were in poor condition, additional field and laboratory studies were carried out. Soil samples were taken for analysis of particle size distribution, unsaturated direct shear strength, and critical stress for erosion. The HEC-RAS data model was used for simulation of hydraulic forces acting at different flow rates. Digital maps of land use in the catchment area in different years were used to estimate changes in runoff conditions over time. MADRAS proved to be a suitable tool for rapid assessment of stability problems in ditches. The HEC-RAS simulations were a good complement to MADRAS in assessing how changes in land use affected the hydraulic load and in highlighting bottlenecks in the system. However, the hydraulic load did not adequately explain the degree of degradation in some ditch segments. Measurements of soil shear strength were a good aid to understanding existing degradation. Thus, assessment of soil erodibility and bank stability is essential in anticipating the risk of future erosion processes in ditches. Keywords: Cohesive strength meter, HEC-RAS, MADRAS, Unsaturated direct shear strength.

Resumen

Abstract. Roadside ditches serve an important role for draining storm water. Over time vegetation growth, natural sediment deposits, and other debris can change grade of ditches. Effectively monitoring and identifying these changes to prioritize ditch maintenance is important from both a pavement preservation perspective and prevention of localized flooding. This study evaluates the performance of two mobile LiDAR systems for mapping the cross-section of roadside ditches in the presence of vegetation. The geometric quality of data collected by two different wheel-based LiDAR systems were investigated. The mapped ditches were reported and visualized in 2D images as well as 3D point clouds. The cross-sections of man-made drainage ditches were extracted and the quality of mapped ditches was assessed against Real-Time Kinematic Global Navigation Satellite Systems (RTK-GNSS) survey. The overall point cloud accuracy was 4 cm for the medium-grade system, and 1 cm for the high-grade system. The mapping accuracy is 2 cm (medium-grade system) and 1 cm (high-grade system) for solid surface. For rough mowed areas and areas with significant vegetation, the vertical accuracy was found to be 7 cm and 11 cm, respectively, for both wheel-based systems.

Resumen

Objective: To obtain analytic dependences for proﬁle cubage volume calculation of subgrades (side hill ﬁlls), ditch cuts (side hill cuts), as well as borrow pits, soil banks, drainage ditches and other structures. Methods: Integral calculus and stereometry was applied. Results: New analytic dependencies for proﬁle cubage volume calculation of subgrades (side hill ﬁlls), ditch cuts (side hill cuts), borrow pits, soil banks and drainage ditches were deducted. Relative errors of calculating the given proﬁle cubage volume were determined in comparison with conventional methods for calculating the values in question. Mathematical demonstration of the given analytic dependencies, as well as the analysis of the latter was carried out. Practical importance: Computational accuracy of proﬁle cubage volume of subgrades (side hill ﬁlls), ditch cuts (side hill cuts), borrow pits, soil banks and drainage ditches may be improved based on the examined dependencies. Research results may be applied in the design of information systems. The latter promptly implement the introduced analytic dependencies of more effective calculation indices and test planning of large earthwork volumes.

Resumen

Within a drainage system, drainage ditches are designed to improve existing natural drainage. Although drainage ditches are mostly engineered, they can also be part of natural watercourses. For environmental sustainability, in many places there are guidelines to establish vegetative buffer strips along the boundary of drainage ditches. In this landscape planning study, a geospatial modeling framework was established to identify these drainage system landforms and the boundary that separates these landforms from their surrounding areas across Waseca County in south-central Minnesota. By employing almost 2000 GPS spot elevation measurements from five ditch systems and one-meter Light Detection and Ranging (LiDAR) derived digital elevation model (DEM) data, the drainage ditch berm polygons were delineated. Eight low light angle hillshade rasters at 45-degree azimuth intervals were used to construct the model. These hillshade rasters were combined to form a composite raster so that the effect of multiple azimuths can be captured during ditch berm delineation. The GPS points identified as the top of the berm were used to extract cell values from the combined hillshade. These cell values were modeled further using statistical distribution graphs. The statistical model derived +0.5 and +1 standard deviation values (cell values 812 and 827, respectively) of the combined hillshade raster were utilized to obtain complete berm polygons. In this semi-automated method, between 67.30% to 79.80% of ditch berm lengths were mapped with an average error that is less than the resolution of the DEM. Demarcation of these boundaries are important for local governments in Minnesota and throughout the world, as it could help guide land–water management and aid sustainable agriculture.

Resumen

Berm drainage ditches may fail due to frost heave in cold and snowy areas like Hokkaido. Many of these failures are regarded to be caused by damage due to frost heave in the ground or freeze-thaw, but no sufficient measures are being taken, as construction guidelines and procedures do not describe any established countermeasures for the damage. Therefore, it was decided to study countermeasures by utilizing berm drainage ditches that can change form in response to frost heave, rather than by trying to reduce the level of change caused by frost heave. A drainage ditch made of flexible asphalt sheets was constructed on site, and the soil temperature, frost penetration depth, frost heave amount, and other parameters were measured. As a result, it was found that a drainage ditch made of asphalt sheets is more effective when ground conditions including moisture and temperature are severe in relation to frost heave.

Resumen

The ditch pattern reflects the distribution characteristics of an agricultural drainage system and needs to be detected to enrich the data source before map generalization. Due to several breaks, the connectivity of the ditches is destroyed between ditches and rivers in map representation, making its structure complex. Previous studies have primarily focused on extracting parallel ditches, paying less attention to complex ditches with breaks. The pattern recognition of ditches does not merely involve the extraction of parallel relation. It involves the extraction of different level relations, which is a great challenge. Therefore, this study proposes a novel model to describe the complex structure of ditches. Our work consisted of the following three main contributions: (1) the collinear relation was defined to detect the groups of ditch segments separated by breaks, (2) the detection method of parallel relation was improved throughout the multi-parameter combined constraints, and (3) the main-tributary relation was proposed to build a connection between parallel groups and rivers. The experimental results showed that the proposed method was solved effectively in complex ditch pattern recognition.

Resumen

Abstract. Localized and artificial groundwater recharge is an important water management strategy in arid regions. However, artificial recharge is limited by the hydraulic characteristics of surface soil which control downward water percolation to the aquifers. In heavy soils with low infiltration and hydraulic conductivity rate, water percolation can be enhanced by constructing deep ditches filled with highly permeable materials, such as sand. Laboratory experiments were conducted to examine the effect of constructing a deep sand ditch across the slope of a soil box (50 × 20 × 25 cm3) on runoff and deep percolation to the drainage outlet of the soil box. A sandy loam soil packed in two bulk densities (1200 and 1500 kg/m3) was used for the experiments. The experiments were carried out using simulated steady runoff of about 300 mL/min for a duration of 60 min. Experimental results showed that sand ditches greatly enhanced water deep percolation in soils but their relative effect was more profound in compacted high-density soil compared to soil having low-density. The drainage water collected from compacted soil boxes in the presence of sand ditches increased by 10 times compared to control soil without sand ditches. In the case of low-density soil, the presence of sand ditches eliminated the runoff but the increase in drainage water was about 18% compared to control. The experimental results clearly revealed that creating high infiltration zones within the soil matrix, such as sand ditches, significantly increased water deep percolation and herewith groundwater recharge in drylands, especially in heavy soils. Keywords: Arid regions, Groundwater recharge, Percolation, Rapid infiltration.

Resumen

Equilibrium analysis is essential to evaluate sorption capacity and to determine whether sediment acts as a source or sink of phosphorus (P). This study was carried out to determine whether or not the sediment in drainage ditches acts as a source or sink of P, evaluate phosphorus sorption kinetics, and determine the potential P sorption by using the Langmuir isotherm sorption model. Surface sediment (0–10 cm) and the overlying water were collected from three drainage ditches for the experiments. Results showed that the drainage ditch that was the most contaminated with P had the highest sediment zero-equilibrium phosphorus concentration (EPC0). Because sediment EPC0 of the three ditches was higher than water P concentration, they acted as a sink of P across the sediment interface. The kinetic sorption of sediments consisted of two stages that were quick and slow, regardless of the sampling sites. The amounts of P sorbed to sediments at equilibrium (Qe) ranged from 50.8 to 77.5 mg kg−1. Phosphorus sorption capacity (Qmax) of sediments ranged from 447.0–493.8 mg kg−1 with the constant related to binding energy (K) (0.140–0.171 L mg−1). The results from this study indicate the importance of ditch sediment in controlling P dynamics in discharge from agricultural farms.

Resumen

Wetlands have been heavily affected by human-alteration, this is done to drain thewetland so that the ground can be used for other purposes such as forestry oragriculture. With high accuracy data available now, it is possible to use differentmethods automatically to identify these ditches in wetlands or other areas. Fourdifferent methods were applied to two areas to delineate ditches. To compare the different methods, the results were quantified by comparing with amanually created map of the ditches. Drainage density and an agreement index wereused. The results indicate that the methods of impoundment index and map gullydepth are best able to distinguish the ditches in wetlands. The former gave a betterresult on areas inside wetlands while the latter gave a better result with non-wetlandareas. The other two methods make mistakes and misjudgements that givemisleading results, they ignore ditches partially or completely, or finds ditches inareas without them. Even so, all methods are at least a clear improvement over thecurrently available property map's water flows, but not in the same class as the timeconsumingmanual method.
Våtmarker har påverkats mycket av människan genom dikning, detta görs för attdränera våtmarken så att marken kan användas för andra syften som skogsbruk ellerjordbruk. Med höjddata i hög noggrannhet som nu finns tillgänglig är det möjligt attanvända olika metoder för att urskilja dessa diken i våtmarker. Fyra olika metodermed applicerades på två olika områden för att undersöka möjligheten att urskiljadiken. För att jämföra de olika metoderna kvantifieras resultaten genom att jämföras meden manuellt skapad karta över diken. Dränerings densitet och ettöverensstämmelseindex användes. Resultaten pekar på att metoderna fördämningsindex (impoundment index) och ravindjupskartering (map gully depth) klarar bäst avatt urskilja diken i våtmarker. Där den föregående ger ett gav ett bättre resultat inomvårmarker och den senare gav ett bättre resultat generellt över området. De tvåandra metoderna gör missar och felbedömningar som ger missvisande resultat.Oavsett det, så är karteringen av dikena i nuläget en klar förbättring överFastighetskartans vattenflöden, men inte i samma klass som den tidskrävandemanuella metoden.

Resumen

Subsurface solute transport is a major mechanism that contributes to the contaminant load in both surface and ground waters. Among these contaminants are plant nutrients that if transported in excessive amounts to surface waters can cause adverse effects on humans and animals, as well as negative impacts on aquatic life. The general objective of this study was to conduct a field evaluation of subsurface solute transport in the capillary fringe (CF) and shallow ground water (SGW) and their contribution to nutrient load in the ditches prior to restoration of a Carolina Bay. Specifically, this study was aimed at evaluating: a) the horizontal flow of bromide (Br-) in the CF and SGW under field conditions, b) the fate of nitrate (NO3-) in the CF and SGW in a sandy field site drained by ditches, and c) the possible contribution of subsurface flow to the increased nutrient load in drainage ditches at a drained Carolina Bay following storm events. The study was conducted in Juniper Bay, a drained Carolina Bay in Robeson County, NC. A solute transport experiment was conducted at a sandy site in the Bay where a solution containing Br- and NO3- was applied into an auger hole dug to about 10 cm above the CF during the time of application. The transport of Br- and NO3- in the CF and SGW was monitored by frequently collecting soil water samples using tension lysimeters installed at depths of 45, 60, 75, 90 and 105 cm at lateral distances of 20, 60, 120, 220 and 320 cm from the auger hole along the general direction of the ground water flow. A representative monitoring site from each of the Bay?s mineral and organic soil areas was also chosen for a year-long monitoring of fluctuations in nutrient concentrations in water samples from the Bay?s main ditch exit as well as from the vadose zone, ground water and lateral ditches. Soil solution from the vadose zone and ground water samples were collected using tension lysimeters installed at 15-cm depth intervals from 15 to 120, and 30 to 180 cm depths at the mineral and organic soil sites, respectively. Ground water samples were collected from three fully perforated wells. Seven piezometers installed at each site also allowed collection of ground water samples from different depth intervals below the water table The direction and magnitude of the subsurface hydraulic gradient at the monitored sites were also determined using the three-point technique. Lateral transport of Br- in the CF was observed in the direction of ground water movement up to 320 cm from the auger hole where solutes were applied. The Br- plume from the unsaturated zone that entered into the CF tended to stay and move horizontally in the CF until it was partially moved into the ground water by the fluctuating WT following rain events. The normalized concentrations (concentration in soil solution/concentration in the applied solution) of both NO3- and Br- in water samples collected from CF were comparable for all distances from the application spot. However, in the groundwater, the normalized concentration of NO3- was substantially lower than the normalized Br- concentrations. We believe the reduction in NO3- concentration in the ground water was due to denitrification. Results from the nutrient monitoring experiment reveal that the sample taken from the main ditch exit following a 5 cm d-1 storm event had higher concentrations of total organic carbon (TOC), phosphates (PO4-P), calcium (Ca) and magnesium (Mg) compared to the average of samples collected during baseflow conditions. The same was also observed for samples collected from the vadose zone especially at depths closer to the soil surface where organic carbon and extractable Ca, Mg and PO4-P contents were higher. Higher concentrations of these solutes in the ditches and vadose zone coincided with observed increase in the magnitude of the groundwater hydraulic gradient. In addition, it was observed that following the storm events, the direction of the ground water hydraulic gradient tended to become more perpendicular to the nearby lateral ditch suggesting that the route taken by the water as it moves in the subsurface towards the ditch is shortened. We believe that the increase in concentration of PO4-P, Ca, Mg and TOC in the soil solution at certain depths in the soil profile coupled with their higher rate of movement in the subsurface towards the ditch following the storm event should have contributed to the increase in concentration of such nutrients in the ditches.

Resumen

Soil erosion is regarded as a major and widespread soil degradation process. The consequences of soil erosion occur both on- and off-site. On-site consequences are particularly important on agricultural land where the redistribution of soil within a field, the loss of soil from a field, the breakdown of soil structure and the decline in organic matter and nutrients result in a reduction of the cultivable soil depth and a decline in soil fertility (Morgan, 1996). Off-site problems result from sedimentation downstream which reduces the capacity of rivers and drainage ditches, enhances the risk of flooding, blocks irrigation canals and shortens the design life of reservoirs (Verstraeten and Poesen, 1999). Sediment is also a pollutant in its own right, and through the chemicals absorbed it can increase the levels of nitrogen and phosphorus in water bodies and result in eutrophication (Steegen et al., subm.). The rate of soil loss is normally expressed in units of mass or volume per unit area per unit time. Young (1969) quotes annual rates of the order of 0.0045 Mg ha-1 for areas of moderate relief and 0.45 Mg ha-1 for steep relief. For comparison, rates from agricultural land are in the range of 5 to 500 Mg ha-1 (Morgan, 1996; Van Rompaey et al., 2000).
