“…High proportion of pesticides, linuron, pyrethrin, chlorpyrifos, or carbaryl has been detected in plants that are grown in ditches, but the distinction between adsorption and absorption (plant uptake) was rarely evidenced (Bennett et al 2005;Crum et al 1997;Garcinuño et al 2006;Kröger et al 2009;Moore et al 2011).…”

“…(Nédélec and Gay 2008). Friction mechanisms that are induced by bed shape and roughness may significantly slow the water flow (Boutron et al 2011;Hösl et al 2012;Jarvela 2002;Kröger et al 2009;Wu et al 1999). Methods to design a single ditch or open-channel cross section in order to minimize roughness have been proposed by Das (2007) and Nourani et al (2009) , for highly vegetated ditches.…”

“…These authors explained this difference by both the vegetation type, which was bushy non-aquatic and poorly flexible, and the low water level compared to the vegetation heights, which violates the theoretical assumptions behind the usual empirical hydraulic laws. In vegetated ditches, vegetation is the main source of roughness (Wu et al 1999) and always increases the hydraulic retention time compared to non-or less-vegetated surfaces (Hösl et al 2012;Kröger et al 2009;Rhoads and Massey 2012). Roughness varies with the resistance and flexibility of plants, the blockage factor that is linked to the vegetation density (Nepf 2012), and the water level compared to vegetation height or roughness height of the ditch bed (Boutron et al 2011;Jarvela 2005Jarvela , 2002Nepf 2012;Wu et al 1999).…”

“…Drainage ditches are often regarded as wetlands (Flora and Kröger 2014;Kröger et al 2008Kröger et al , 2009) in lowlands with temperate and humid climates. These ditches also present some physicochemical similarities with small lakes and streams (Verdonschot et al 2011).…”

“…Ditch maintenance is a combination in time of dredging, mowing, chemical weeding, and burning ( Fig. 1) techniques (Needelman et al 2007;Kröger et al 2009;Levavasseur et al 2014). Designing the best ditch characteristics and maintenance practices requires a thorough knowledge of their impacts on the underlying biotic and abiotic processes that are involved in the provision of the expected ecosystem services.…”

Agriculture must now feed the planet with the lowest environmental impact. Landscape management is a means to protect natural resources from the adverse impacts. In particular, the adequate management of ditches could improve crop quality. Here, we review ditch design and maintenance. We found the following major points: (1) ditch networks have been primarily designed for waterlogging control and erosion prevention. Nonetheless, when properly managed, farm ditches provide other important ecosystem services, namely groundwater recharge, flood attenuation, water purification, or biodiversity conservation. (2) All ditch ecosystem services depend on many geochemical, geophysical, and biological processes, whose occurrence and intensity vary largely with ditch characteristics. (3) The major ruling characteristics are vegetative cover; ditch morphology; slope orientation; reach connections such as piped sections and weirs, soil, sediment and litter properties, biota, and biofilms; and network topology. (4) Ditch maintenance is an efficient engineering tool to optimize ecosystem services because several ditch characteristics change widely with ditch maintenance. For instance, maintenance operations, dredging, chemical weeding, and burning improve waterlogging and soil erosion control, but they are negative for biodiversity conservation. Mowing has low adverse effects on biodiversity conservation and water purification when mowing is performed at an adequate season. The effects of burning have been poorly investigated.

Agricultural drainage ditches are common as temporary storages of drainage water and may improve mitigation capacity of pollutants in Sanjiang Plain. Few ditch management practices have been proposed to alleviate nitrogen loads transported to downstream aquatic systems in this area. This study examined the nitrogen variation in overlying and pore water of a planted and natural drainage ditch of equal size and shape, as well as the low and high water levels of a planted drainage ditch in Sanjiang Plain. Results indicated that longer retention time was in favor of nitrogen removal in overlying water, especially for ammonium nitrogen (NH 4 -N); high water level undermined nitrogen removal; there was no significant difference with retention time between the planted drainage ditch and the natural drainage ditch. Conversely, NH 4 -N and nitrate nitrogen (NO 3 -N) concentrations in pore water were lower in the planted ditch and high water level planted ditch than in the natural ditch. At present, farmers and managers keep drainage ditches nearly full of water to expediently irrigate, which may increase pollutant load in downstream receiving systems. Thus, our study is helpful in guidance for pollution control of agricultural nonpoint source in Sanjiang Plain.

The contributions of drainage ditches to the accelerated eutrophication of rivers have rarely been assessed, especially for the Three Gorges Reservoir (TGR) drainage ditches. Forty drainage ditches in the TGR from multiple land use types were extensively investigated for 10 parameters of water quality. The results showed that the concentrations of total nitrogen (TN) and total phosphorus (TP) in the TGR drainage ditches were generally far higher than the internationally recognized eutrophication threshold. Based on this study, both ditch water and sediments from residential land and roadside land had the highest concentrations of nutrients. Possible sources of these nutrients include sewage water and septic tank overflow. Forestland had significantly lower concentrations of nutrients. Residential ditches had higher values of electrical conductivity (EC) and total dissolved solid (TDS) values and lower dissolved oxygen (DO) concentrations. Forestland had lower values of EC and TDS values and higher DO concentrations. The results indicate that the nutrients that have accumulated in the sediments have significant impacts on the water quality in adjacent ditches. A long‐term plan must be developed to more strictly control the external loading of nutrients from surrounding land. Action plans to promote the growth of wetland plants in drainage ditches are important for increasing agrochemical retention in the TGR drainage ditches. TGR drainage ditches from residential zones must be actively managed by cleaning and sediment removal to control the risk of nutrients being released into the reservoir.
